Modular Body Support Structure for Adjustable Working Postures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for supporting the human body in various positions, such as standing and sitting, are not comprehensively integrated and lack extensive adjustability in height and depth, making them unsuitable for multifunctional working systems like production lines, where ergonomic and anatomical requirements vary significantly.
Innovation Solution
A device comprising multiple support elements connected to longitudinal bars, allowing for adjustable positioning in height and depth, with eccentric rotation capabilities and interchangeable cushion surfaces to accommodate different body parts, enabling comprehensive support for the feet, knees, back, and head, and featuring a floor element that can be rotated and secured for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing support devices are used, then they provide basic support function, but they lack comprehensive adjustability in height and depth and cannot accommodate multiple body positions
Solution Approach 1:
The device is divided into multiple support elements (fundament support, back support, knee support, head support, foot support) that can be independently adjusted. Each support element is connected to longitudinal bars through adjustable mechanisms, allowing individual positioning without affecting other supports. This segmentation enables comprehensive adaptability while maintaining manageable structural complexity through modular design.
Solution Approach 2:
The device integrates multiple support functions into a single system that can accommodate various body positions (sitting, standing, kneeling, lying). The longitudinal bars and support elements work together to provide universal support for different anatomical regions, making the device suitable for multifunctional working systems in production lines rather than requiring separate devices for each function.
2Adaptability or versatility
If support elements are fixed in position, then the structure is simple, but the device cannot accommodate different user sizes and ergonomic requirements
Solution Approach 1:
The device incorporates adjustable mechanisms that allow support elements to be dynamically repositioned along the longitudinal bars. Users can modify height and depth positions according to their body dimensions and ergonomic needs. The adjustable design transforms a static structure into a dynamic system that adapts to different users while maintaining operational simplicity through intuitive adjustment mechanisms.
3Adaptability or versatility
If only fundament support is provided, then the device structure is simple, but it cannot provide comprehensive ergonomic support for multiple body parts
Solution Approach 1:
The support system is segmented into distinct functional elements (fundament support, back support, knee support, head support, foot support), each targeting specific body parts. This segmentation allows comprehensive ergonomic support for multiple body parts while keeping each individual support element relatively simple in design, managing overall complexity through functional decomposition.
