Description:
We're looking for small and sleek aesthetic designs for a hard-hat clipable safety notification system for construction workers to improve their work safety.
Wants:
1.) Aesthetics
2.) Unique and effective method for attachment to hard-hat.
3.) Manufacturable: build to standards for plastic mold injection.
4.) Meet size constraints
5.) Slim design (does not obstruct field of view when wearing hard hat)
Don't Wants:
I don't want a large/fat design. Please design to the minimum tolerances allowed for plastic mold injection.
Software:
  1. AutoCAD (Latest)
Additional Information
Additional Wants:
- Water-resistance
- Front-case and button fused. We'll use a multi-material plastic injection mold. Button will be a rubber-like material with a column that makes contact with the PCB snap-dome.

Score Breakdown:

Aesthetics (25 pts) | 25/25: Design is pleasing to the eye.

Manuafaturability (25 pts) | 25/25 : The design can easily and cost-effectively be adapted for plastic injection molding.

Housing Attachment (20 pts) | 20/20 : The design features a unique and effective method for attachment to the brim of a hard-hat.

Design Novelty (10 pts) | 10/10: The design does not reflect any characteristic design features of earlier entries or current available products.

Designer Interactions (10 pts) | 10/10: Designer actively engages with Buyer.

Water Resistance (10 pts) | 10/10: The housing is water-proof.

Hello Everyone,

Congratulations to HandSketcher for 1st place prize with a small, thin, and attractive design!

I'm attaching a score sheet in the attachments for everyone to see how they were graded.

Thank you to all participants! We really loved everyone's input and the great submissions.

Please go check out our 2nd Project "Hard-Hat Clipable Safety Notification System ()" focused more on manufacturability and building around a specific PCB.

Hi Everyone,

We're closing the competition at 11:59 pm (Pacific Time Zone) Saturday April 8th, so please submit your final designs before that time.

We'll be hosting another competition very soon focusing more on designing a housing around a specific PCB instead of conceptual like we did this time.

As this this was our first project Cad Crowd, we'll do a better job this second time with awarding 1st,2nd,3rd prizes, funding the project upfront, and keep the project time down to 10 days.

Thank you all for you submissions, we've very happy with the results we've gotten so far, and we're happy to work with you guys on future projects!!

@Samadoni: only the user needs to see the LEDs, but it's ok if both see the LEDs.

Do the lights have to be visible only for the the person wearing the hat, or for other coworkers? or both?

Hi SL:

We didn't provide that information since we'd like to see some creativity in aesthetics and safety-hat placement. The PCB design is open to change. Please focus more on coming up with a creative, aesthetic, and novel housing for this application. We've provided PCB specifications and images just for an example reference so you can get an idea of the basic components and basic size the housing should be.

So to summarize, this is more of a concept-design competition instead of designing a housing for one specific PCB.

Hi Ux,

I'll prepay the project once we get 5 quality design entries.
Wed, 29 Mar 2017 02:54:39 +0000
I think payment for the contest must be completed for getting good designs as it gives confidence for all the CadCrowd designers. I hope all the CadCrowd designers would agree with me.

Thanks,

I apologize for not including that information.

PCB Thickness: 0.6 mm

Please feel free to post any further questions.

Hi John, could I have the assembled pcb height. I'll have what you need complete fairly soon.
Many thanks

@Abid:
Please forgive me for not explaining it better, this is our first project posting on Cad Crowd. The safety notification system is accomplished with the internal electronics already developed. You will be designing the outer casing to house and protect the printed circuit board. All that is important is that there are LEDs on the curved portion of the case to display threats, there is a push-button in the center of the case, there is a micro-USB charging port on the side and the case will be clipped somehow to the underside of a hard-hat.

Hope that helps.

Hey there,
what all do you want to include in the safety notification system, it will be helpful if you can tell me the field of work where the hat will be used.
Are you sure you don't want a 3D simulated model and just an Auto CAD file.

I understand perfectly.
Sounds good.

Hi Samadoni:
All I'm allowed to say is: the device has internal sensors to notify construction workers of nearby dangers.
If we like your design concepts, we can issue a mutually protective "Non Disclosure Agreement" and spill our beans.

Could you please explain what a "safety notification system" is ...
please specify the function in more detail ...

300 sqm 3D floorplan sketch
I have a land and I'm planning to make a 4 floor building for a residential purpose . The design should be a modern style apartment .the land size is 700 sqm but the allowed space for building is 300 sqm . I need to see 2 different designs as this : First design : The floor should consists of 2 apartments , first apartment to have 3 bedroom and the second apartment to have 2 bedroom . Both apartments must have at least 1 master bedroom , a living room and a hall with setting and dining area . I suggest the size to be 170 for the 3 bedroom and 130 for the 2 bedroom . There should be built in wardrobes . Second Design : Should consist of 2 apartments , first apartment to be a 3 bedroom apartment with all masters and a small clothing room in one of the master rooms. it should have also a big hall , living and children playing room if possible . The size of the apartment should not exceed 230 - 240 sqm . The other studio apartment should not exceed 60-70 sqm . I have attached 3d designs that I really liked but it doesn't fit my land plan . I also have attached an autocad floorplan that has been mad by one of the local designers but it didn't meet my expectations but I attached it for your understanding . Please note that the ground floor apartments should have 2 Entrance , one entrance is the Main stairs entrance that leads to other top floors and the elevator and the other one is a side entrance for each apartment in the ground level . You may notice that the setback area is shown in one of the designs attached which should be mined .

iPhone Audio Accessory - Music Booster
This product provides an added volume boost to iPhones. Ultimately, we'd like to create an audio booster accessory that plugs directly into an iPhone. You would then be able to plug your headphones into this accessory so you can listen to your music at louder levels. We'd like to have it so you can control the volume/bass/treble levels through a mobile app. If not, then it could be something like this FiiO product (http://fiio.net/en/products/53) but wireless. It would also be similar to this product, but also wireless. https://www.kickstarter.com/projects/1746450443/uamp-soul-shaking-audio-for-your-ears/description No firm dimensions. At most, it would be as wide as the iPhone itself. Design should look like something Apple would have designed. Something sleek. For colors, use the same colors as the iPhone 6S. There needs to be a Power button, Vol+ button, Vol- button, and either a battery indicator or battery light.
