Y-Shaped Key Handle for Limited-Dexterity Turning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with limited manual dexterity face difficulties in handling and manipulating keys due to the unique properties required for their proper use, such as picking up, inserting, and turning, which existing devices fail to address effectively.
Innovation Solution
A Y-shaped handle, potentially made from antler or wood, is attached to a key, providing the necessary geometric and structural requirements for picking up, inserting, and turning the key, with a curved design and a lanyard for wrist retention, allowing users to exert the necessary forces for key operation.

Engineering Contradiction Analysis
1Reliability
If the handle is made with extensive friction surfaces for secure gripping, then the user can maintain grip on the device, but the device becomes more complex and harder to manufacture
Solution Approach 1:
The lower gripping portion of the handle incorporates porous or textured surfaces that increase friction and grip retention. These textured surfaces can be created through simple molding or casting processes, providing enhanced grip without requiring complex assembly or additional components.

AI summary
A device attachable to a utensil that allows an individual with limited dexterity to handle the utensil and use it according to its ordinary function. The device provides a Y-shaped handle, such as that structured by a section of antler, that attaches to a utensil and provides the geometric and structural requirements necessary for the user to pick up the utensil from a flat surface, direct the utensil near the material to be manipulated, and manipulate the utensil once positioned. The Y-shaped component is curved across its height and provides a wedge engagement structure to permit holding the device with utensil to exert a force directing the utensil into the material to be manipulated, and by a combination of forces exerted by the palm and the thumb, to grasp and manipulate the device combination in order to make appropriate use of the utensil for its intended purpose.
