Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional spring leaf lock catches or spring lock catches are used, then the lock catch structure is simple, but the style is single, elasticity decreases over time, and spring leaves may break
Solution Approach 1:
The lock catch is divided into separate components: a buckle body, a buckle sleeve, and a spring assembly. This segmentation allows each part to be optimized independently - the buckle body can be designed in various styles while the spring assembly provides reliable elastic function, resolving the contradiction between style variety and reliability.
Solution Approach 2:
The lock catch uses a dynamic spring mechanism that maintains constant elastic force through proper spring design and positioning. The spring is housed in a dedicated chamber with a stopper to prevent over-compression, ensuring consistent reliability while allowing the buckle body to vary in style.
2Ease of operation
If magnetic lock catch is used, then the lock catch operation is convenient, but it is easily opened by chance or small external force
Solution Approach 1:
The patent replaces magnetic locking mechanism with a mechanical spring-based locking system. The spring provides controlled elastic force to secure the buckle, and the addition of a stopper prevents over-compression and accidental release, maintaining ease of operation while significantly improving security against accidental opening.
Solution Approach 2:
The stopper is positioned beforehand in the spring chamber to limit the compression distance of the spring. This prevents the spring from being over-compressed and accidentally releasing, providing beforehand cushioning against potential failure modes while maintaining the convenient push-to-lock operation.
3Volume of stationary object
If threaded lock catch is used, then the lock catch volume is small, but threads at both ends are not easily butt-jointed while in use
Solution Approach 1:
The patent extracts the threading function from the lock catch body itself and relocates it to the buckle sleeve and connecting mechanisms. The lock catch body focuses on the spring-based locking function, while the buckle sleeve with its inlet and connecting mechanisms handles the thread attachment, separating concerns and improving ease of operation.
Solution Approach 2:
The buckle sleeve acts as an intermediary component between the lock catch body and the jewelry chain threads. It provides a dedicated interface with an inlet for inserting threads and connecting mechanisms for securing them, making thread attachment much more convenient than direct threading through the lock catch body.
4Ease of manufacture
If lock catch body shape is fixed, then the manufacturing is simple, but the style is single and lacks molding change
Solution Approach 1:
The lock catch is segmented into a standardized buckle body with spring mechanism and a separate buckle sleeve. The buckle body can be manufactured in standard configurations for simplicity, while the buckle sleeve and connecting mechanisms can be varied in design to create different styles, allowing both easy manufacturing and style variety.
