Wearable Resizing Structure for Secure Fit on Varying Body Shapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices often struggle to maintain a secure fit on varying body parts due to differences in thickness and shape, leading to discomfort and potential detachment during use.
Innovation Solution
A wearable device with a resizing structure that includes an elastic member and a supporting member, which is deformable according to the shape of the body part, and a fastening member that applies pressure to secure the device in place, allowing for adjustable sizing to accommodate different thicknesses and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size wearable device is used, then the device structure is simple, but it cannot accommodate varying body part thickness and shape
Solution Approach 1:
The wearable device incorporates a resizing structure that transitions from a static configuration to a dynamic one, allowing the device to change its dimensions and shape in response to pressure from the body part. The elastic member enables the device to expand or contract, adapting to different thicknesses and contours while maintaining structural integrity.
Solution Approach 2:
The device utilizes an elastic member that changes its physical parameters (length, shape, rigidity) in response to applied pressure. This parameter change allows the device to accommodate varying body part dimensions without requiring multiple fixed-size configurations, thereby reducing overall device complexity while improving adaptability.
2Adaptability or versatility
If a resizing structure with elastic member is added, then adaptability to body shape is improved, but device complexity increases
Solution Approach 1:
The wearable device is divided into distinct functional segments: a frame providing structural support, a resizing structure with an elastic member for adaptation, and a fastening member for securing. This segmentation allows each component to perform its specific function efficiently, reducing the complexity that would arise from a monolithic design while achieving customizable fit.
Solution Approach 2:
The elastic member acts as a flexible element that can deform to match the contours of the body part. This flexible component enables the rigid frame to adapt to various shapes without requiring the entire device to be complex and flexible, thus achieving customizable fit with minimal added complexity.
3Ease of operation
If the resizing structure is made more movable, then comfort and fit are improved, but stability and security of the device decrease
Solution Approach 1:
Different parts of the wearable device have different degrees of movability and rigidity. The elastic member and resizing structure provide local flexibility for comfort and fit adjustment, while the frame and fastening member maintain local stability and security. This distribution of qualities across different locations resolves the contradiction between movability and stability.
Solution Approach 2:
The device employs a dynamic system where the resizing structure can move and adapt during the putting-on process to ensure comfort and proper fit. Once adjusted, the fastening member locks the resizing structure in place, transitioning the system from a dynamic state to a stable state, thereby maintaining both comfort and security.
4Reliability
If a fastening member is added to press the elastic member, then device security is improved, but device complexity increases
Solution Approach 1:
The fastening member is integrated with the existing frame and resizing structure, merging multiple functions into a unified system. The fastening member works in conjunction with the elastic member and frame to provide both security and adaptability, reducing the need for separate, additional components and thereby minimizing the increase in device complexity.
