Magnetic Wearable Strap Link for Secure Sliding Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable electronic devices face challenges in easy and secure attachment to the user's body, particularly due to the difficulty in operating small levers or buttons for detachment and the need for replacing straps, which often requires purchasing the entire link assembly.
Innovation Solution
A wearing member for wearable electronic devices featuring a strap, cover assembly, and a link assembly with magnetic members that allow for easy detachment and attachment by sliding a button member, utilizing magnetic forces to secure the connection to the device housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional lever or button mechanism is used for attachment/detachment, then the connection is secure, but the operation becomes difficult and inconvenient
Solution Approach 1:
The patent replaces the traditional mechanical lever or button system with a magnetic field-based attachment mechanism. The magnetic members (permanent magnets or electromagnets) create magnetic attraction forces that securely hold the wearable electronic device to the wearing member, while allowing easy attachment and detachment without complex mechanical operations. This substitution of mechanical system with magnetic field system directly resolves the contradiction by providing both ease of operation and reliable connection.
2Adaptability or versatility
If the entire link assembly is purchased for strap replacement, then the attachment mechanism remains intact, but the cost and complexity increase
Solution Approach 1:
The patent divides the link assembly into separate, independent components: the magnetic members are integrated into the housing, while the attachment mechanism on the wearing member is designed as a separate component that can be independently replaced. This segmentation allows users to replace only the strap or wearing member without needing to replace the entire link assembly, reducing both cost and complexity while maintaining the integrity of the attachment mechanism.
3Ease of operation
If magnetic members are used for attachment, then ease of operation improves, but the magnetic force control becomes critical
Solution Approach 1:
The patent addresses magnetic force control by carefully selecting and positioning magnetic members with specific magnetic field strengths and orientations. The design incorporates multiple magnetic members at different locations and orientations to create a balanced magnetic field that provides sufficient attachment force while allowing easy detachment. This parameter optimization (magnetic field strength, distribution, and orientation) resolves the contradiction by ensuring both ease of operation and controllable magnetic force.
