Wearable Device Strap Connector for Tool-Free Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable devices require a special tool for disassembly, making it inconvenient to replace components such as batteries or sensors, as they typically need to be disconnected using a housing from a cover.
Innovation Solution
A wearable device design featuring a housing with a locking pin and cover hook system, where a strap with a connector allows for latching and unlatching by bending, eliminating the need for a special tool by applying pressure to disengage the cover from the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a special tool is used to disconnect the housing from the cover, then the device can be disassembled, but it requires buying a special tool and is inconvenient
Solution Approach 1:
The strap serves a dual function: it secures the device during use and acts as the disassembly tool when bent. The connector on the strap directly engages with the locking pin to release the housing cover, eliminating the need for external special tools. The device uses its own components (strap and connector) to perform the disassembly function.
2Stability of the object's composition
If the housing and cover are securely latched, then the device is stable during use, but it requires a special tool to open
Solution Approach 1:
The locking mechanism transitions from a static locked state during use to a dynamic release state when the strap is bent. The connector can move between engaged and disengaged positions relative to the locking pin, allowing the system to adapt between providing secure connection during use and enabling easy opening when needed.
3Strength
If a connector secures the strap to the housing and cover, then the strap is firmly attached, but it requires bending the strap to apply pressure for disassembly
Solution Approach 1:
The strap system is divided into functional segments: the strap body for securing, the connector for engagement with the locking pin, and the bending zone that applies mechanical pressure. This segmentation allows each part to perform its specific function while keeping the overall disassembly mechanism simple and intuitive.
