Wearable Seat Unit with Rotatable Connection for Posture Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable sitting posture assisting devices do not adequately adjust to individual anatomies and postures, leading to discomfort and limited versatility in sitting and walking modes.
Innovation Solution
A wearable sitting posture assisting device with a self-adjusting seat unit featuring rotatable and displaceable connections, a flexible sitting element, and a restoring mechanism, allowing the seat surface to adapt to different sitting angles and positions, providing a comfortable and stable seating experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed seat unit design is used, then the device structure is simple, but the wearing comfort and adaptability to different postures are poor
Solution Approach 1:
The seat unit incorporates a rotatable connection between the sitting means and frame means, allowing the seat surface to dynamically adjust its orientation based on the user's posture. This enables the seat to adapt between walking posture, sitting posture, and partly sitting posture, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The seat unit is divided into separate components: frame means, sitting means, and rotatable connection. This segmentation allows each component to be optimized independently while maintaining overall adaptability, enabling the seat surface to rotate relative to the frame to match different user postures.
2Adaptability or versatility
If the seat surface is fixed relative to the frame, then the manufacturing is simple, but the adjustment to individual anatomy is not adequate
Solution Approach 1:
The rotatable connection enables the seat surface to dynamically reorient itself according to the user's anatomy and posture rather than requiring multiple fixed-size options. This single dynamic structure replaces what would otherwise require multiple manufactured variants, maintaining ease of manufacture while improving anatomical adaptation.
3Ease of operation
If the sitting means is rigidly connected to the frame, then the structural stability is high, but the wearing comfort in different positions is reduced
Solution Approach 1:
The rotatable connection provides conditional stability: the seat surface can rotate to maintain optimal alignment with the user's body during posture transitions, while the frame means remains stable for weight bearing. This dynamic adjustment enhances wearing comfort without compromising the overall structural stability of the device.
