Posture support device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing posture support devices lack the ability to adjust the position and angle of the support member in multiple directions, leading to inadequate adaptation to individual differences in skeletal structure and muscle strength, resulting in discomfort and posture instability.
Innovation Solution
A posture support device featuring a fixing plate separately attached to the seat back, allowing the support member to be positioned and angled freely in various directions, with a design that minimizes movement during use and incorporates protruding surface portions for enhanced contact area and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the support member is fixed to the seat back with limited adjustment capability, then the device complexity is reduced, but the adaptability to individual differences in skeletal structure and muscle strength deteriorates
Solution Approach 1:
The support member is designed with adjustable mechanisms that allow dynamic repositioning in multiple directions (up-down, right-left, front-rear) and angle adjustment. The fixing plate provides a stable base while the support member can be positioned at various locations and orientations to adapt to different user anatomies, transforming a static structure into a dynamically adjustable system that accommodates individual variations in skeletal structure and muscle strength.
Solution Approach 2:
The device is divided into separate functional components: a fixing plate that attaches to the seat back and a support member that can be independently positioned and angled on the fixing plate. This segmentation allows the support member to be adjusted relative to the fixing plate without affecting the overall attachment stability, enabling fine-tuned adaptation to individual user needs while maintaining structural integrity.
2Adaptability or versatility
If the support member position and angle are adjustable in multiple directions, then the adaptability to individual differences is improved, but the device complexity increases
Solution Approach 1:
The fixing plate serves multiple functions: it provides a stable attachment point to the seat back, serves as a mounting surface for the support member, and enables multi-directional adjustment capabilities. By consolidating these functions into a single universal component, the design achieves high adaptability without proportionally increasing overall device complexity.
Solution Approach 2:
The fixing plate acts as an intermediary between the seat back and the support member. It provides a stable interface that allows the support member to be adjusted in multiple directions and angles while maintaining secure attachment. This intermediary component simplifies the adjustment mechanism by decoupling the attachment function from the positioning function, reducing overall system complexity.
3Ease of operation
If the fixing plate is easily movable with respect to the seat back, then the ease of operation is improved, but the stability of the support device deteriorates
Solution Approach 1:
The fixing plate is designed with dynamic attachment characteristics that allow easy adjustment during installation and repositioning, but provide stable fixation during use. The attachment mechanism enables operators to easily move and reposition the fixing plate on the seat back, yet once positioned, it maintains stable attachment that prevents unintended movement during normal use, achieving both ease of operation and operational stability.

AI summary
It has at least one fixing plate arranged on the seat back and at least one support member arranged on the fixing plate, and the support member can be arranged at an arbitrary angle at an arbitrary position on the front surface of the fixing plate. Therefore, the position of the support member can be adjusted not only in the vertical direction but also in the horizontal direction with respect to the seat back, but also in the angle. Therefore, it is possible to increase the degree of freedom in the position and the angle of the support member as compared with the related art.
