Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility devices for individuals with limited mobility require arm or hand use, lack speed control, and are not height adjustable, posing safety and support issues.
Innovation Solution
A hands-free mobility device with adjustable height, swiveling wheels, and a hands-free braking system using paddles to control speed, allowing users to maneuver safely and independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional walkers or stability devices are used, then they provide basic mobility support, but they require arm or hand use which limits accessibility for individuals with limited upper extremity functionality
Solution Approach 1:
The device enables self-service mobility through body weight activation. The user's body movement automatically activates the braking and propulsion mechanisms without requiring manual operation, allowing individuals with limited upper extremity functionality to independently control the device
Solution Approach 2:
The patent replaces traditional manual mechanical control systems with a body-weight-activated mechanical system. The braking mechanism is triggered by the user's natural body movement rather than requiring hand operation on traditional walker handles
2Reliability
If traditional mobility devices are used, then they provide basic movement capability, but they lack speed control and braking mechanisms which creates safety issues
Solution Approach 1:
The braking mechanism is merged with the propulsion mechanism into a single integrated system. The same body-weight activation that propels the device forward also triggers the braking function, eliminating the need for separate control components and reducing overall device complexity
Solution Approach 2:
The braking system operates automatically through body weight activation without requiring separate manual control. When the user applies body weight to the activation mechanism, it simultaneously controls both propulsion and braking functions
3Adaptability or versatility
If traditional walkers are used, then they provide stability support, but they are not height adjustable which limits adaptability to different users
Solution Approach 1:
The device incorporates dynamic height adjustment capabilities that allow the frame height to be modified according to different user requirements. The adjustable support members can be positioned at multiple height levels to accommodate users of various statures

AI summary
A stable walking apparatus can be used to allow the elderly, disabled, injured, or infirmed to move for day-to-day activities and exercise. The apparatus supports the individual at an upper body portion, such as under the arms of the user. This allows use of the arms and legs of the individual, such as better balance and move with the device, while also controlling aspects of the device. The support is height adjustable, and also includes a braking system to both slow down and stop the user-apparatus. The braking system can be used with limited extremity functionality for greater use of the apparatus by a wide range of individuals. Swiveling wheels provide for additional functionality to use the device for more purposes and in increased locations.
