Auxiliary Moving Device Cushion Positioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary moving devices for disabled individuals are unsafe and difficult to maneuver during daily activities like bathing, as the seat is locked to the chair legs, making it hazardous to move the person.
Innovation Solution
An auxiliary moving device featuring a first cushion with support members and a positioning mechanism, where the cushion moves on the support members using a post inserted into holes, allowing for secure fixation and easy movement with the aid of a spring, stopping piece, and pull ring mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the seat is locked on legs of the auxiliary chair, then the stability of the device is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent applies the dynamics principle by implementing a movable positioning mechanism where the post can be inserted into different holes on the support members. This allows the device to transition between fixed (stable) and movable (easy to operate) states, resolving the contradiction between stability and ease of operation. The positioning mechanism enables dynamic adjustment of the cushion's position on the support members.
2Reliability
If the seat is locked on legs of the auxiliary chair, then the reliability of the device is improved, but the ease of operation deteriorates
Solution Approach 1:
The positioning mechanism with multiple holes and a post allows the device to achieve reliable fixed positions when needed while maintaining ease of operation through simple insertion and removal actions. The spring-loaded stopping piece ensures reliable positioning once the post is inserted into a hole, while the overall mechanism remains easy to operate.
Solution Approach 2:
The post acts as an intermediary element between the cushion and the support members, enabling reliable connection when inserted into the holes. This intermediary mechanism provides a simple yet effective way to achieve both reliability and ease of operation, as the post can be easily inserted or removed to secure or release the cushion position.
3Stability of the object's composition
If the cushion is fixed on support members, then the stability of the device is improved, but the adaptability deteriorates
Solution Approach 1:
The positioning mechanism with multiple holes at different positions on the support members enables the cushion to be fixed at various locations, providing both stability when fixed and adaptability through repositioning. The spring-loaded stopping piece allows the post to engage with different holes, enabling the device to adapt to different positioning requirements while maintaining stability at each position.

AI summary
An auxiliary moving device contains a first cushion and two support members disposed on two sides of the first cushion. The first cushion is allowed to move on the support members, with one of the two support members including a plurality of holes. A positioning mechanism is fixed on the first cushion and includes a post. The post is inserted into one of the holes of the one of the two support members to fix the support member.
