Symmetrical Belt Buckle Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt buckle designs are complex and difficult to lock and unlock, posing a risk of accidental operation and increased production costs due to non-symmetrical and non-identical components.
Innovation Solution
A belt buckle arrangement featuring identical or symmetrical first and second belt buckles with matching locking devices and hooks, allowing for a simple and secure connection that requires simultaneous actuation of both locking devices for detachment, and enabling cost-effective production by using identical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex locking mechanisms are used to prevent unintentional opening, then reliability is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The locking device features an asymmetrical design where the locking direction is enabled while the unlocking direction is blocked by a blocking element. This asymmetry prevents unintentional opening while maintaining a relatively simple mechanical structure, resolving the contradiction between reliability and device complexity.
Solution Approach 2:
A blocking element is introduced as an intermediary component that prevents the locking element from disengaging in the unlocking direction. This mediator ensures reliable prevention of unintentional opening without requiring a complex multi-component locking mechanism.
2Reliability
If complex locking mechanisms are used to ensure secure connection, then reliability is improved, but ease of operation worsens due to difficulty in locking and unlocking
Solution Approach 1:
The locking mechanism uses asymmetrical geometry where the locking movement is freely enabled while the unlocking movement is blocked. This allows secure connection through simple insertion without requiring complex operational steps, improving ease of operation while maintaining reliability.
3Reliability
If non-identical and non-symmetrical components are used for locking, then reliability may be improved through differentiated design, but ease of manufacture deteriorates due to increased production complexity and cost
Solution Approach 1:
The locking device is designed with universal symmetry so that identical components can be used for both locking and unlocking functions. This symmetrical design allows a single component type to perform multiple functions, significantly simplifying manufacturing and reducing production costs while maintaining reliable locking functionality.
Solution Approach 2:
The patent employs homogeneous materials and identical symmetrical components throughout the locking mechanism. This homogeneity simplifies the manufacturing process by reducing the variety of parts that need to be produced, assembled, and quality-checked, thereby improving ease of manufacture while preserving locking reliability.
