Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility devices for amputees are often cumbersome, unstable, non-adjustable, difficult to maneuver in tight spaces, and lack sufficient storage capacity, posing challenges for users with different body shapes and preferences, and can discourage users due to their unattractive appearance.
Innovation Solution
A mobility device with an articulating frame, steerable wheels, a cushioned support member, and adjustable features such as a pocket for receiving an amputated leg, foldable design, and optional outriggers for protection, allowing for stable and versatile use across various surfaces and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing mobility devices are designed with fixed structure, then manufacturing is simpler, but adaptability to different body shapes and preferences is poor
Solution Approach 1:
The seat is designed with adjustable height and angle capabilities, allowing it to adapt to different user body shapes and preferences. The backrest can be adjusted to different angles and the seat height can be modified, transforming a static structure into a dynamic one that responds to user needs.
Solution Approach 2:
The mobility device incorporates multiple functions including seat adjustment, storage compartments, and adjustable handlebars, making it suitable for a wide range of users with different body types and needs, thereby achieving universality.
2Ease of operation
If mobility devices have fixed width, then structural design is simpler, but maneuverability around corners and through narrow spaces is poor
Solution Approach 1:
The frame is divided into modular sections that can be adjusted and reconfigured. The handlebars are separable and adjustable, and the overall structure can be adapted to different width requirements, improving maneuverability in tight spaces.
3Adaptability or versatility
If mobility devices lack storage capacity, then device structure is simpler, but ability to transport items is limited
Solution Approach 1:
Storage compartments are integrated into the overall device structure, combining the transportation function with storage capability. The compartments are built into the frame and seat structure, merging multiple functions into a unified design.
4Adaptability or versatility
If mobility devices are not adjustable, then device complexity is lower, but ability to accommodate different users is poor
Solution Approach 1:
The device incorporates multiple adjustable features including seat height, seat angle, and handlebar height, transforming a static device into a dynamic one that can adapt to different users through mechanical adjustment mechanisms.

AI summary
An amputee mobility device includes a wheeled frame, and seat with webbed pocket for receiving an amputated leg. The seat is adjustable height adjustable, as is the pocket for customizing to individuals. Adjustable handles allow amputees to move themselves, or allow a helper to push like a wheelchair. In one form, the frame includes front and rear articulated subframes. In another form, the wheeled frame forms an elongated rigid frame, with two fixed-axle wheels and two rear-located steerable wheels and one front-located steerable wheel. In another form, the frame includes two fixed-axle wheels and two steerable wheels arranged to function somewhat like a wheeled walking cane. Optional features include outriggers for leg protection, a foldable frame for compact storage and shipment, bicycle-like lockable hand brakes, a seat without aperture for supporting a lower leg extending horizontally, storage shelves, and cup holders.
