Telescopic Strap Mechanism for Wearable Sensor Donning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable physiological signal detecting devices are inconvenient for users to put on and take off due to their fixed size and design.
Innovation Solution
A wearable physiological signal detecting device featuring a telescopic structure within a strap that allows the first and second surfaces to move from a contacting state to an angled state, expanding the wearable space for easy donning and doffing, utilizing a fixing member, telescopic members, recovery members, and a limiting structure to manage the angle and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the strap has a fixed size design, then the device structure is simple and stable, but the user finds it inconvenient to put on and take off
Solution Approach 1:
The strap incorporates a telescopic structure that allows dynamic adjustment of its size. The strap can transition between a compressed state for easy putting on and an expanded state for comfortable wearing, making the device adaptable to different user needs while maintaining operational convenience
Solution Approach 2:
The strap is divided into multiple telescopic members that can slide relative to each other. This segmentation allows the strap to change its effective length and volume, enabling easy putting on and taking off while maintaining structural integrity when worn
2Ease of operation
If the telescopic structure allows large angle movement, then the wearable space expands for easy donning, but the recovery members may deform excessively
Solution Approach 1:
The limiting structure is designed to prevent excessive angle movement before it can cause damage to the recovery members. By establishing a maximum angle constraint in advance, the system protects the recovery members from over-stretching and deformation while still allowing sufficient movement for easy putting on and taking off
Solution Approach 2:
The system changes the parameter of maximum allowable angle through the limiting structure. By defining a specific angle threshold, the system optimizes the balance between expanding wearable space for ease of donning and preventing recovery member deformation, adapting the geometric parameter to protect component integrity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device allows for convenient and easy placement and removal, enhancing user experience by adjusting the wearable space size, while ensuring the recovery members do not deform excessively and maintaining medical and hygienic safety through detachable components.
Implementation Method 1
The plurality of recovery members are respectively connected between two adjacent telescopic members and continuously provide elasticity so that each of the first surfaces and the corresponding second surface which are adjacent to each other assume the first state

AI summary
A wearable physiological signal detecting device includes a device main body and a telescopic structure. The device main body has a strap which surrounds to form a wearable space. The telescopic structure is disposed in the strap and has first surfaces and second surfaces. Each of the first surfaces faces the corresponding second surface. Each of the first surfaces and the corresponding second surface continuously move close and contact each other to assume a first state. The strap can be forced so that each of the first surfaces and the corresponding second surface move away from each other and have an angle to assume a second state. The size of the wearable space when the first surface and the corresponding second surface assume the second state is greater than the size of the wearable space when the first surface and the corresponding second surface assume the first state.
