Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buckles, especially the closed type, are difficult to lock and unlock due to complex structures, have weak fastening force, and can be easily released unintentionally, posing safety risks and manufacturing cost challenges.
Innovation Solution
A buckle design featuring a male and female buckle member with integrated magnets and sliding locking/unlocking mechanisms, including a releasing rotation plate and elastic member, allowing for easy one-handed operation and secure fastening with rapid release capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional closed type buckle is used, then the fastening force is maintained, but the buckle is difficult to lock and unlock due to complex structure
Solution Approach 1:
The buckle is divided into distinct functional components: a body member with locking protrusions, a strap member with locking grooves, and a pressing member. This segmentation allows each component to perform its specific function independently, simplifying the overall operation while maintaining structural integrity and fastening force.
2Reliability
If a conventional closed type buckle is used, then the fastening force is maintained, but the buckle can be easily released unintentionally
Solution Approach 1:
The pressing member acts as an intermediary mechanism that mediates between the user's action and the locking/protrusions. When pressed, it transfers force to slide the strap member relative to the body member, enabling controlled release. This intermediary ensures the buckle only releases when intentional pressure is applied, preventing accidental release while allowing easy release when needed.
Solution Approach 2:
The buckle employs a dynamic sliding mechanism where the strap member can move relative to the body member along the pressing direction. This dynamic interaction between the locking grooves and protrusions allows the buckle to transition between locked and released states based on applied force, providing reliability during normal use and ease of release when pressed.
3Reliability
If magnets are integrated into the buckle members, then secure fastening is achieved, but the manufacturing complexity increases
Solution Approach 1:
The magnets are integrated directly into the body member and strap member structures, merging the magnetic fastening function with the mechanical structure. This combining approach eliminates the need for separate magnetic components or additional assembly steps, thereby maintaining secure fastening while avoiding increased manufacturing complexity.
