Description:
I am looking for an experienced mechanical CAD engineer / vehicle packaging designer to develop an ultra-compact electric wheelchair platform vehicle in Fusion 360.

This is NOT a styling contest.

I need a technically plausible engineering concept for a compact outdoor-capable platform that allows a wheelchair user to drive in:
- supermarkets and tight indoor environments
- roads and sidewalks
- gravel paths, forest trails, mountain paths
- fields and uneven terrain

IMPORTANT:
This is a PLATFORM — not a buggy, not a vehicle with a roof, not a large chassis.

NO roof
NO cabin
NO unnecessary body panels

The design must act like a “second skin” around the wheelchair:
- extremely compact
- tightly packaged
- stable and robust
- outdoor capable

Core requirements:
- Fusion 360 ONLY
- realistic mechanical concept (no renders only)
- max width: 750 mm
- max length: 1200 mm
- wheelchair width reference: 650 mm
- rear entry mandatory

Rear entry must be solved via:
- automatic ramp OR
- lowering rear chassis OR
- equivalent realistic mechanism

Outdoor capability:
- must handle rough terrain
- proper wheel size (no tiny wheels)
- real suspension concept
- stable center of gravity
- realistic ground clearance

Speed requirement:

Speed requirement:

This platform should NOT be limited to slow indoor speeds (e.g. 3–6 mph / 5–10 km/h).

The design must be engineered with the potential for higher speeds in mind (e.g. 12–25 mph / 20–40 km/h), depending on drivetrain configuration.

This has direct impact on:
- stability
- suspension design
- chassis rigidity
- center of gravity
- wheel size and geometry

The concept must reflect this and be structurally plausible for higher-speed operation, not only low-speed indoor use.

This must NOT be designed only for smooth indoor floors.

A gyroscope stabilization idea is welcome but optional (must be technically explained if used).

What I expect in submissions:
- top view
- side view
- chassis layout
- wheel & suspension concept
- drivetrain packaging
- wheelchair integration
- rear entry solution
- explanation of engineering logic

Fusion 360 native files preferred.
STEP optional, but Fusion source required.
The design does NOT have to be created in Fusion 360.

Other CAD software such as SolidWorks or similar is fully acceptable.

IMPORTANT:
Final deliverables must include a STEP file (.STEP / .STP) that is fully usable and editable.

Native CAD files are welcome but optional.

This contest is to find a serious engineer for a paid follow-up project.
Wants:
1. Technical plausibility (MOST IMPORTANT)
2. Real outdoor capability (not just visual)
3. Compact packaging around wheelchair
4. Realistic wheel and suspension design
5. Rear entry solution quality
6. Stability and center of gravity
7. Maneuverability in tight spaces
8. Engineering understanding (not styling)
9. Fusion 360 experience
10. Potential for follow-up project collaboration
Don't Wants:
- AI-generated images
- render-only concepts
- Blender-only work
- pure styling / industrial design sketches
- generic buggy concepts
- oversized vehicles
- ANY design with a roof
- cabin or body-heavy designs
- unrealistic wheel sizes
- no suspension logic
- ignoring rear wheelchair entry
- ignoring size constraints
- sci-fi / fantasy concepts
- designs that are clearly not buildable

If your submission is not a real engineering concept, it will be rejected.
Ask for Sample:
Please provide: 1. Examples of Fusion 360 mechanical CAD work 2. Experience with chassis / suspension / vehicle design 3. Short explanation of your approach 4. Confirmation that you can deliver editable Fusion 360 files 5. Confirmation that your submission is NOT AI-generated Samples should be shared via private message if required.
Software:
  1. Autodesk Fusion 360
  2. SolidWorks
Additional Information
IMPORTANT ADDITION / CLARIFICATION:

The platform must be electrically powered and controlled via joystick (wheelchair-style control).

Outdoor capability is a mandatory requirement.

This means:
- Proper wheel size suitable for rough terrain (no small wheels)
- Real suspension concept is required
- Stable and robust chassis

Submissions with:
- small wheels
- no suspension
- concepts only suitable for smooth indoor floors

will be ignored and not considered.

Please ensure your design is truly outdoor-capable and mechanically realistic.

Hello,

I am submitting a fully engineered concept for the ultra-compact electric wheelchair platform as requested.

This is a mechanically realistic design developed in Autodesk Fusion 360, focusing on true outdoor capability, compact packaging, and structural feasibility — not styling.

Key highlights:
- Fully compliant with size constraints (≤ 750 mm width, ≤ 1200 mm length)
- Independent suspension on all four wheels for real terrain use
- Dual motor drivetrain for maneuverability and redundancy
- Low center of gravity with underfloor battery placement
- Hybrid rear entry system (active lowering + ramp)
- Wheelchair-integrated docking system for safety and stability

The design is engineered with scalability for higher speeds (up to ~40 km/h), with proper consideration of stability, suspension geometry, and chassis rigidity.

Deliverables included:
- Editable Fusion 360 file (.f3d)
- STEP file for compatibility
- General arrangement and mechanism drawings

This submission is a genuine engineering concept and not AI-generated or render-only.

I would be glad to further refine this into a production-ready design or collaborate on the next stage.

Best regards,
Shekhar Chandra Biswas

Do you want each part to be designed separately and then assembled together, or do you prefer that the entire system is built all at once as a single piece?
This project is the same one that was posted at least one week ago.

I noticed that there are specific design constraints in this contest. Will the previous submission be closed or not evaluated?

Design for mini-WiFi Router - Product in Big Box Retail Q1 2016
This project is for a small WiFi router plastic injection mold that needs to look like a "shield". The PCB (circuit board) is: 2.5 inches in length 1.5 inches in width .5 (half an inch) at its highest point We have included three screenshots of the current injection mold which needs to be redesign. These are JUST for reference to see what the current plastic mold looks like: current-injection-mold-1.jpg current-injection-mold-2.jpg current-injection-mold-3.jpg We have also included a screenshot of the PCB (circuit board) titled: pcb-1.jpg Please note that on that pcb-1.jpg screenshot there are two antennas or wires with green rectangles. Those will be "stuffed" into the mold and have no requirements as far as plastic pieces that need to house or hold them. We will just be pushing them into the hollow area of the mold between the PCB and plastic. What we are trying to do is change our current mold into a plastic shield. Our request is to have a plastic "shield" designed that can house the PCB. This may require the design of the shield to be thicker in height to properly hold the PCB. What we are looking for is AutoCAD design comps of what the new injection mold could look like as a shield, using the very basic dimensions we have outlined above. In regards to the design, we have attached a PDF titled: concept-shield-spec-sheet.pdf This is a VERY basic spec sheet and "concept" design of a shield that we created in house. You do not need to make the design look exactly like this. This spec sheet is just "ideas" we had for a design that would look like a shield and fit the PCB. Designers have full creative freedom to come up with some designs that fit the PCB. We have attached four screenshots of shield designs we like from a company called Vmoda: http://v-moda.com/over-ear-shields/ On that link, the designer can find MANY more ideas on shields V-moda's website all of which we like. Please note that V-moda is just an example of shield designs we like. We know they are a headphone company and have nothing to do with us other than we like their designs. The screenshots are titled: shield-ideas-1.jpg shield-ideas-2.jpg shield-ideas-3.jpg shield-ideas-4.jpg We LOVE these designs and think they could easily work with our PCB which would be underneath the shield. Designers have creative freedom when it comes to the texture on top of the shield, color and most everything else. If the designer so desires, we would even be open to adding additional "non-plastic" elements to the shield design such as "chrome inlays" or "metal edging" etc. This is not a requirement. We just want everyone to know that they can add other materials to the design if they think it will really make the product standout. We do also ask that the designer incorporates our logo into the design of the shield. Our logo is attached in both PSD and PNG format and titled: abox.png abox.psd If there are any questions, please don't hesitate write us. Thanks!

Open Air Photo Booth
To design an "open-air" photo booth that is modern and clean in appearance as well as minimal and compact in function. The design can either be modular or as one piece but absolutely must be light weight, very durable and very portable. In terms of appearance, think apple products such as the ipad, imac, etc. If the design is modular, there will need to be cases designed to go along with the pieces or the modules must fit in commonly available cases. In terms of materials, I am open to any and everything but again, they most be light, strong, durable, not show a lot of wear and not too expensive to work with. Wants: All designs must incorporate these necessary components: - A Ring Flash (10" diameter, 9.5" depth, weighs aprx. 5lbs) Photo attached - A DyeSub Printer (10.7" W, 6.6" H, 13.3" D, weight 24 lbs.) Photo attached - An Ipad or touchscreen monitor of similar size - A secondary monitor any size from 10"-19" - A Mac Mini (7.7" W, 1.4" H, 7.7" D, 2.7 llbs) - A second ipad For the camera element / user interface, the ring flash and one ipad/touchscreen monitor must be facing the customer and combined into one module/unit. (The actual DSLR camera mounts to the ring flash with the lens sitting in the center of the ring flash.) This unit would also house the Mac mini and possibly the secondary monitor. The mac mini should be hidden from view. The secondary monitor can be on the side or back of the camera module but in full view to the customer. The lens of the camera will need to sit at 43" from the ground (at it's lowest setting) and be able to be raised to 53" and 58" off the ground (at its highest setting.) This can be an adjustable height mechanism that allows for any height desired in between those specs or by using 2-3 different length adjustments that can be interchanged. It must be on a stable design that will not easily be tipped over. There will need to be a hidden door/access in order to power on the internal components, adjust camera settings, etc. For the printer, it can be housed in the same unit as the camera but if you decide to go this route, the entire unit must be as small and light weight as possible. Otherwise, if you go the modular route, it can be in it's own module or combined with the secondary ipad into it's own module. The printer must be at least 22" off of the ground when being used. The printer is the most delicate of all components so where ever it's placed, it absolutely must be secured and safe from being knocked over. It also must be easily accessed from the front since it has a sliding drawer that opens when the paper and ink are changed. The printer has to be physically tethered via usb cable to the mac mini, so keep that in mind. The secondary ipad's purpose is for customers to be able to use and interact with it. It will need to be at a comfortable height for the average adult user. It can be paired with the printer or if with the camera, the camera module must be 100% stable and able to take the abuse from customers using the ipad without affecting the front components. With all of these components, they need to look seamless. No hinges or screws or other hardware or cables visible. Ideally the entire set up would be primarily white with accents of red and/or aluminum. Very clean, very modern, very simple. It's imperative that the design can withstand countless drunk customers, be very stable, not get damaged or scratched (beyond repair) and all break-down/packed up to easily fit into the trunk/boot of a mid-sized car. It can pack down to one easily transportable case or 3 modules maximum. If one, it must be easy and secure to move, ideally with wheels. These components will be set up in all sorts of different locations from private residences, ballrooms, lobbies, back yards, etc. hence the reason it needs to be light weight, compact and durable as well as adjustable. I have attached a pdf showcasing several different versions of "open-air" photo booths to give you some ideas of what's being done and how much of it could be improved upon.
Revolutionary Meditation Bench
A standard meditation bench made of wood gets a makeover. We are looking to create a fully-adjustable, lightweight, travel version of a wooden meditation bench for manufacture via injection molding (plastic). Here is a reference for what it usually looks like (not what we are making): http://www.samadhicushions.com/Meditation-Bench-Seiza-Kneeling-Bench-p/C-564.htm?Click=9556 The bench consists of 2 legs, of the same size, 7.5 inches tall. Atop is a main sitting piece, which is at right angles to the legs and is 18 inches long and 7 inches deep. All parts are ½ inch thick, or thinner. The bench needs to be able to support the weight of an adult. The main sitting piece (piece “A” in the sketch) needs to be rotational such that it can be tilted forward in order to create an angled seating platform. This adjustment is to conform to the seating angle of the meditator to create comfortable sitting position. The piece must lock out once in place at the desired setting, in order to provide stability while sitting on it (aka it does not move). The legs must also be retractable, such that they fold in towards the main sitting piece in some manner, in order to make the bench small and practical for travelling or storage. When folded, teethe assembly should ideally be no more than 1 inch thick.
Ice Sphere Storage Tray
-Our company is looking to develop a unique Ice Sphere Storage Tray for 60mm Ice Spheres -The Storage tray will be sold as an Accessory item to our main Ice making unit. (See rendered image attached) -We would like concepts for a Single holder and a 4 sphere holder (combined bottom portion and individual but identical top pieces) -You can see a couple simple concepts we have made, These should be elaborated on, although we would like to keep the release feature on the top portion (method for pressing out the ice sphere with no contact necessary). (See example holders attached) -Feel free to draft preliminary ideas for feedback before refining. We will be monitoring the project regularly throughout the work week to help provide timely feedback. Contest will run for 14 days.
