Orthopedic Seat Support with Spring-Locked Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthopedic seat supports require labor-intensive adjustments and take up significant space when folded for transportation or storage, making them inconvenient for use and storage.
Innovation Solution
A support system for orthopedic seats featuring a pivotally mounted body with a locking mechanism, comprising pins, guides, and compression springs, allowing for quick folding and unfolding of the supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the support is designed to be folded for transportation, then the storage space is reduced, but the adjustment process becomes labor-intensive and time-consuming
Solution Approach 1:
The support system incorporates compression springs that automatically push the support body during the unfolding process, enabling the support to assist its own adjustment without requiring significant manual effort. The springs store mechanical energy during folding and release it during unfolding, making the system self-serving.
Solution Approach 2:
The support transitions between static locked positions (folded and unfolded) through a dynamic unlocking mechanism. The pin-and-opening locking mechanism allows the support to be quickly released from the folded position, enabling rapid transition between storage and operational states.
2Stability of the object's composition
If the support uses a locking mechanism to maintain position, then the stability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a pin mounted on the support body, an opening in the mounting element, and compression springs in separate guides. This segmentation allows each component to perform its specific function independently while maintaining overall system simplicity.
Solution Approach 2:
The locking function is extracted as a separate mechanism from the main support structure. The pin-and-opening locking system operates independently from the support body's primary functions, allowing the locking mechanism to be simplified and focused solely on its locking purpose without interfering with other support functions.
