Sliding Magnetic Fastener for Non-Parallel Vehicle Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic fasteners struggle to maintain a secure connection between vehicle parts due to manufacturing tolerances that result in non-parallel surfaces and varying distances between parts, leading to inconsistent contact and connection failure.
Innovation Solution
A magnetic fastener design incorporating a magnetic connector, a support bracket with a hole, a bottom support with a neck that is slidably connected to the support bracket, and an elastic member, such as a spring, which allows for dynamic adjustment to accommodate different spacings and angles between vehicle parts, ensuring a robust and stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnetic fastener is used to connect two vehicle parts, then the connection is simplified and easier to install, but the connection reliability deteriorates when manufacturing tolerances cause non-parallel surfaces or varying distances between parts
Solution Approach 1:
The support bracket is designed with a sliding mechanism that allows it to move dynamically along the magnetic connector's axis. This dynamic adjustment enables the support bracket to accommodate varying distances between vehicle parts caused by manufacturing tolerances, maintaining reliable magnetic connection without requiring precise parallel alignment
Solution Approach 2:
The invention changes the positional parameter of the support bracket relative to the magnetic connector by allowing sliding movement. This parameter change enables the system to adapt to different spacing conditions while maintaining connection reliability, resolving the contradiction between ease of installation and connection reliability
2Ease of manufacture
If a fixed magnetic fastener design is used, then the structure is simple and manufacturing is easy, but the adaptability to different spacings and angles between parts deteriorates
Solution Approach 1:
The support bracket incorporates a sliding mechanism that provides dynamic adjustability while maintaining a relatively simple overall structure. The sliding feature allows the bracket to adapt to different spacings and angles without requiring complex mechanisms, thus preserving ease of manufacture while significantly improving adaptability
Solution Approach 2:
The magnetic fastener is divided into separate components: a magnetic connector and a support bracket that can slide relative to each other. This segmentation allows the support bracket to independently adjust its position to accommodate manufacturing tolerances, enhancing adaptability without substantially complicating the manufacturing of individual components
