PROBLEM STATEMENT

Kimberly currently suffers from Ushers Syndrome, impacting her vision, hearing, and sense of touch. She can only recognize objects when they are in high contrast to each other, and she finds trouble cooking food which splashes when in contact with oil and high temperatures. A team of engineers have come together to create a product which aids her while cooking, which is easy to apply, clean, and operate. The product must take into consideration her impaired vision, lack of feeling on her fingertips, and her limited hearing. It must also fall under the budget of 100$.

04. Product Description & Use

Designed to enhance safety and convenience in the kitchen
Features an interchangeable attachment at the base
Equipped with a sturdy handle for easy stabilization and transportation
Thoughtfully designed steam hood on the top facilitates steam release
Important features are coloured differently for easy visibility and orientation.

To use, simply place on top of the pot, lining up the markings on the underside to secure it. Using the handle, turn the spinner to mix the food!

Spray bottle to simulate oil splashing
0L of water passed through lid

Contrast:

9.18:1 contrast ratio of relative luminance

Ability to clean:

Point out of 10 taken off for each difficult to clean component
8/10

Ease of use:

User feedback: 9/10

Stirring Smoothness:

User feedback: 7/10

05. DESIGN REFINEMENTS

The testing plan highlighted flaws in the mechanism including:

Wobbling stirring mechanism
Uncomfortable handles
Difficult to clean/use sliding vent

Refinements/Iterations after testing:

Tolerances between the axle and stirring handle were changed re-printed

Extension was printed for handle on pot lid

Sliding vent was replaced with open vent

Handle to keep pot in place before testing refinement

Handle to keep pot in place after testing refinement

Stirring mechanism

The pot lid features a manual stirring tool, giving the user complete control over their cooking.

Detachable Parts

The end of the stirring rod can be switched to different stirrers, dependant on the cook’s needs…

Ridged Edges

To use it on a variety of pot sizes, the edges were engraved with creases to fit on all your favourite pots!
