Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection devices for assemblies are not space-saving, cost-effective, and do not facilitate a reliable connection between assemblies, often requiring complex and bulky mechanisms.
Innovation Solution
A magnetic connection device with integrated sewing areas on the connecting parts, allowing for a seam connection that positions the seam close to the magnetic elements, enabling a compact and robust attachment that can withstand forces while allowing for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection devices are used, then connection reliability is achieved, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple functions into the connecting parts: magnetic attraction for connection force, engagement projections for mechanical interlocking, and integrated sewing areas for permanent attachment to assemblies. This merging of functions reduces overall device complexity while maintaining connection reliability.
Solution Approach 2:
The connecting parts are segmented into distinct functional elements: magnetic elements for attraction, engagement projections for locking, and sewing areas for attachment. This segmentation allows each element to be optimized independently while working together to provide reliable connection.
2Strength
If conventional connection devices are used, then connection strength is achieved, but the area and volume of the connection device increase
Solution Approach 1:
The patent concentrates the connection functions in localized areas on the connecting parts. The magnetic elements, engagement projections, and sewing areas are all positioned in specific local zones, allowing strong connections without increasing the overall area of the connection device.
Solution Approach 2:
The engagement projections are designed to nest into corresponding recesses on the opposing connecting part, creating a compact interlocking structure that provides strong mechanical connection without increasing external dimensions.
3Ease of operation
If the sewing area is positioned far from the magnetic element, then engagement projection engagement is facilitated, but the seam distance to magnetic element increases reducing force transmission efficiency
Solution Approach 1:
The patent positions the sewing area, magnetic element, and engagement projections in a three-dimensional arrangement where the sewing area is offset in one dimension while the magnetic element and engagement projections operate in another dimension. This spatial arrangement allows both the sewing area to be close to the magnetic element for force transmission and the engagement projections to engage properly.
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 solution provides a reliable, space-efficient, and cost-effective connection between assemblies, with a seam that maintains close proximity to the magnetic elements, facilitating force transmission and allowing for emergency separation if needed.
Implementation Method 1
The first and second magnetic elements attract each other magnetically to facilitate the connection of the first and second connecting parts
