Magnetic-Mechanical Locking Device for Textile Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices struggle to provide a flexible, simple, and cost-effective connection between rigid and flexible assemblies, particularly when the flexible assembly is a textile component, as they often require direct attachment that can be costly and complicates production and recycling.
Innovation Solution
A closure device with a connecting part that includes a fastening device for attaching the second closure part to the assembly, allowing for a bayonet connection that can be securely fixed and easily detached, enabling flexible adaptation to the assembly's shape and facilitating recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second closure part is directly attached to the flexible assembly, then the connection is secure, but the production cost increases and recycling becomes difficult
Solution Approach 1:
The closure device is divided into separate components: a connecting part that attaches to the flexible assembly and a closure part that provides the magnetic closure function. This segmentation allows the closure part to be detached and recycled while the connecting part remains with the assembly, resolving the contradiction between secure connection and recyclability.
Solution Approach 2:
The connecting part serves as an intermediary component between the flexible assembly and the closure part. It provides a standardized attachment interface that secures the closure part while allowing for easy detachment and recycling, thus maintaining connection security without compromising manufacturability or recyclability.
2Stability of the object's composition
If the second closure part is firmly connected to the assembly, then the connection is stable, but the magnetic elements may be damaged during assembly production
Solution Approach 1:
By separating the closure part containing magnetic elements from the assembly integration process, the magnetic elements are protected from damage during production. The connecting part without sensitive magnetic elements is attached to the assembly first, then the closure part is secured to the connecting part, ensuring magnetic element protection while maintaining connection stability.
Solution Approach 2:
The connecting part is attached to the flexible assembly before the closure part with magnetic elements is secured. This preliminary attachment of the non-magnetic connecting part creates a stable base that protects the magnetic elements from damage during subsequent assembly operations.
3Strength
If a rigid connection is used between the closure part and assembly, then the connection is strong, but the adaptability to flexible assembly shapes is reduced
Solution Approach 1:
The connection system is segmented into a flexible connecting part that adapts to the assembly shape and a rigid closure part that provides strong magnetic closure. The connecting part's flexibility allows adaptation to various assembly shapes while the closure part maintains strong connection strength through magnetic attraction.
Solution Approach 2:
The connecting part is designed with flexible characteristics that allow it to conform to the shape of the flexible assembly. This flexibility in the connecting part enables strong overall connection while adapting to varying assembly geometries, without requiring the closure part itself to be flexible.

AI summary
A locking device (1) for connecting two assemblies (5, 6) comprises a first locking part (2) associated with a first of the assemblies (5, 6) and having a first magnetic element (24), and a second locking part (3) having a second magnetic element (34). The first locking part (2) and the second locking part (3) can be attached to one another along a closing direction (X) by magnetic attraction between the first magnetic element (24) and the second magnetic element (34), are held together mechanically and/or magnetically in a closed position, and can be separated from one another to open the locking device (1). A connecting part (4) has a fastening device (41) for attaching the second locking part (3) to the connecting part (4) and an integration section (42) for fixing the connecting part (4) to a second of the assemblies (5, 6).
