Problem
Conventional chairback support structures face difficulties in adjusting the position, height, and curvature of the human back resting portion, limiting their effectiveness in providing optimal support.
Innovation Solution
A chairback support structure featuring a back element with insertion holes and resilient bend plates that can be adjustably mounted to facilitate user-controlled adjustments in position, height, and curvature, combined with lateral support elements and a pad for comprehensive back support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional chairback support structure is used, then the structure is simple and easy to manufacture, but adjustment in the position, height and curvature of the human back resting-portion is difficult
Solution Approach 1:
The back element is divided into multiple segments including a central back board, two lateral back boards, and multiple resilient bend plates. Each segment can be independently adjusted and positioned using insertion holes and positioning posts, enabling customized adjustment of position, height and curvature while maintaining a modular structure that is relatively easy to manufacture.
Solution Approach 2:
The resilient bend plates are designed to be bendable and adjustable, allowing the curvature of the back support to be dynamically changed according to user needs. The plates can be inserted at different positions and bent to different degrees, providing dynamic adaptability rather than a fixed structure.
2Adaptability or versatility
If resilient bend plates are made bendable and adjustable, then customization of back support is enabled, but manufacturing precision and assembly complexity increase
Solution Approach 1:
The system uses multiple discrete resilient bend plates with standardized insertion portions that fit into pre-drilled insertion holes. This segmentation allows for easier manufacturing of individual components with standard tolerances, while the assembly provides precise customization through the selection and positioning of specific plates.
Solution Approach 2:
The resilient bend plates are designed with self-positioning capabilities through their insertion portions and abutting portions that fit into corresponding holes and against the back element. This self-service design reduces the need for high-precision manual assembly while still achieving accurate positioning and customization.
