Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic buckles have an unstable connection between the buckle base and clamping head due to unreasonable structure design, limiting their ability to rotate 360° and making them inconvenient to use, as they require two hands and can only be fastened and separated at a single angle.
Innovation Solution
An automatic magnetic buckle design featuring a clamping head with a cavity containing a buckle subassembly and a buckle base with matching magnetic subassemblies, along with a fastener unfolding device and pressure spring, allowing for secure connection and 360° rotation, enabling easy separation and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a magnetic subassembly is added to the buckle, then the automatic connection function is improved, but the connection stability between buckle base and clamping head deteriorates
Solution Approach 1:
The buckle is divided into separate magnetic connection components (magnetic blocks in clamping head and buckle base) that can automatically attract and connect. The segmentation allows independent optimization of each component's magnetic properties while maintaining overall connection stability through distributed magnetic forces across multiple contact points.
Solution Approach 2:
The magnetic subassembly integrates magnetic blocks, elastic components, and clamping structures into a unified system. The magnetic attraction force merges with mechanical elastic force and physical clamping to create a multi-mechanism connection that overcomes the instability of magnetic-only connection.
2Device complexity
If the buckle is designed in a flat shape with single-angle fastening, then the structure is simple, but the ease of operation deteriorates as it requires two hands and cannot rotate 360°
Solution Approach 1:
The buckle transitions from a static flat design to a dynamic structure where the clamping head can rotate 360° relative to the buckle base. The elastic components and magnetic subassembly enable dynamic movement during fastening and separation, allowing one-handed operation and flexible positioning while maintaining structural simplicity.
3Extent of automation
If the clamping head and buckle base are magnetically attracted, then the automatic magnetic connection is improved, but the separation capability deteriorates as they cannot be easily disconnected
Solution Approach 1:
The elastic components are pre-loaded to create a mechanical separation force that counteracts the magnetic attraction force. When separation is needed, this pre-stored elastic energy is released to push the clamping head away from the buckle base, overcoming the magnetic hold without requiring excessive manual force.
Solution Approach 2:
The magnetic blocks and clamping surfaces are designed with curved geometries that allow for easy disengagement. The spherical or rounded contact surfaces reduce friction and enable smooth separation motion, allowing the magnetic connection to be broken with minimal force applied at any angle during rotation.
