Self-heating Tumbler Design

in Product Design held by Topi
Contest Ended, Winner(s) have been selected.
We are a new venture specializing in the creation of Self-Heating Tumblers. Our tumblers (travel mugs) are quality made with precision and self-heat themselves by the press of a button. The button initiate a reaction inside the tumbler chambers, causing the interior to heat up.

We are looking for a concept/prototype design in 3D. We have attached design specifications and photos describing the product.
Has to be modern, slender, simple, and delicate culminating in an eye-catching fancy quality product. Preferably the exterior to be made of aluminum or heat-resistant metal.

The product is a hot cup system. The system has a generally cylindrical exterior member with a cylindrical side wall and with an open upper end and an open lower end. The exterior member is molded from a thermally insulating heat-resistant metal. The system also has a generally cylindrical interior
member with a cylindrical side wall with an open upper end and a lower end With a generally planar circular lower portion. The lower portion is formed with laterally spaced
downwardly extending parallel projections. The interior member is fabricated of a thermally conductive metallic material. A circular base is next provided With a central
section extending downwardly therefrom. The base is fabricated of a resilient clear elastomeric material and is coupled to the interior surface of the exterior member adjacent to the lower end thereof a chamber is formed between the interior member and exterior member and base. A heat generating fluid is located Within the chamber. A generally hemispherically shaped trigger is formed of a exible metallic material located above the central section of the base.

We are looking for a concept that looks similar to the Starbucks 2012 Stainless Steel Tumbler. **A photo has been attached**

#24 Tumbler v3 by DaBu
This is my concept with vacuum chamber.
Assembly goes like this:
1. Bottom plate is glued to the bottom of the vacuum chamber.
2. You put inside the previously assembled trigger mechanism (trigger disk, spring and support). The support has the following advantages:
- eliminates the protruding elements from the bottom of the
liquid chamber (difficult to manufacture)
- holds the spring and the trigger disk
- centers the trigger disk at assembly point.
3. Mount the ring on the liquid chamber
4. Mount the above assembly inside the vacuum chamber
Notes: bottom plate and ring should be glued to assure sealing for the hot liquid chamber.
5. External coat is added - you can use different materials, markings, logo and then just switch them
6. Top (lid) has two additional elements that can be easily assembled: silicon seal and sliding cover.
If there are any questions please don't hesitate to ask.

Redesigned the top according to your specs. I separated the cutout from where you drink from the area where you control the cover: I consider being more hygienic this way. The sliding piece is easy to assembly and its shape prevents from falling inside the tumbler. I hope that the image is suggestive enough. I attached the STEP file wich is standard for 3D model and can be opened in most modelling programs. I can provide detailed dimensional drawings and STL files for 3D printing as well. The ratio between reservoir volume and heating liquid chamber volume can be easily adjusted once you know what your needs are. If there's anything else that I missed please tell.

Hey robhare, an explanation list for the numbered parts is provided within the attachments. Dimensions are open-ended, however preferably if you follow something similar to below.
Dimensions: 2.7” wide at the widest point of the lid x 7.0”H x 2.6” at middle point of mug x 2.5” diameter at base.

Also, preferably it should look very similar to the "Starbucks 2012 Black Stainless Steel Tumbler".

hi do you have dimensions and names list for your numbered parts.
For Don't Wants , Do you want a complicated look or a non complicated look ?

Animal Hideaway
I would like to design a more moden hideaway for guinea pig, hamsters, rabbit etc. I would like to keep still wood pine house since these animals will bite it up. I would like it to be more of a luxury look but still in the same sizing because most customers will buy a small starter cage to fit it in. I will post an example in the pictures of sizing of cage. Guinea Pigs have an issue pulling there food and water bowls in there hide aways and spill everything. I would like the food and water bowls to be attached to the house with a bowl holder where I can remove the bowls on and off to fill up. I would like the food and water bowl to be ceramic. A window can be made where the animal sticks there head out the window to the bowl drink and eat the food easily while inside there home. Attached are pictures of a hideway would like it around that same size. Food and water bowl would like it to be more that shape. Animal Cage picture the hide away would have to fit in that cage size.
Stylish Case for a Car Key
We are looking for some concept sketches for a key case. An innovative key case design which can hold a typical car key (attached picture). The case itself should be able to fit on a key ring. The key should be completely hidden inside the case until the case is opened (by some creative means or mechanism) to reveal the key, either in whole or part – at least, so the user can press the buttons on the key itself. We are looking for a high-end, upscale design, which combines smooth-functionality with luxury and desirability. A pleasure to look and feel, a pleasure to simply hold in your hand. A status object and a pleasure to use, again & again - perhaps damped - with an extremely desirable finish, perhaps piano black, brushed steel or rose gold ... following an interface design associated with the modern iPhone-types. However all design finishes will be considered.
Macbook Pro case design
The case will be 2 parts. A top and a bottom. We'll use this design as the basis for a case we plan to manufacture. See attachments for dimensions and measurements. The design should be able to easily scale to fit both the 13" and 15" models, but the 15" is our priority. You must have a retina Macbook to determine the exact curve of the case and to make sure there are holes on the sides near the bottom for the vents ( These cases are both similar to what we're looking for: Any of the following file formats are acceptable: .stl .3ds .dae .blend
Control-box with display, fitting on a DIN rail
This is about a first product draft, which shall later be turned into a production ready design. I need an enclosure for a custom made electronic part. The rough form-factor should be similar to a navigation system (see attached files) with a display in front and parallel enclosure boundaries, slightly rounded edges. The display is 4.3 inches wide (see technical details attached) and should be included in the rendering. The enclosure should be 4 cm deep. As a bonus, the display shows attached bar diagram. At the back, there should be the possibility for a DIN rail mount, top hat rail EN 50022 – 35 × 7.5 but also for direct wall mount using screws or mounting to a bar with cable ties. At the front left side of the enclosure, I need a C14 inlet to add a power cable and a Schuko socket: or CEE 7/3 socket. See attached figure of the design. The material should be dark grey with a bit reflective surface. Please add our logo to the upper left corner of the front, below the display. If it fits optically, it could glow a bit in green.
Innovative Hearing Protection for Dogs
Please help me design an innovative hearing protection system for dogs! Dogs, much like people, have sensitive hearing that may be damaged by continuous, loud noises. I would like to design a product that will provide passive noise reduction for dogs who adventure - ride on airplanes, go to the shooting range, and attend concerts. The main goals of this product are to (1) provide hearing protection, (2) be secure on the dog's head, (3) be comfortable for the dog, and (4) be highly adjustable. Existing hearing protection products have noise-cancelling ear muffs secured around the dog's head with straps (see Attachment #1). However, this style is easily removed by the dog and tends to shift when the dog moves. Further, the chin strap may choke the dog. Please provide an innovative, improved product design that reduces harmful noises and comfortably secures to the dog's head so that it stays in place when the dog moves. It need not have "earmuffs". Feel free to bring a never-before seen solution!
