Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connection is used for coupling objects, then the coupling strength is improved, but the ease of separation deteriorates and assembly becomes cumbersome
Solution Approach 1:
The fastening apparatus is divided into separate components: a base unit and a clasp body that can independently engage and disengage. The clasp body is further segmented into a body portion and a locking portion that can move relative to each other, enabling quick release without affecting the entire fastening system.
Solution Approach 2:
The locking portion is designed to be movable relative to the body portion, transitioning between locked and unlocked positions. This dynamic mechanism allows the clasp to quickly engage and disengage from the base, providing ease of separation while maintaining coupling strength when locked.
2Strength
If screw connection is used for coupling objects, then the coupling strength is improved, but the assembly time increases
Solution Approach 1:
The clasp body is pre-configured with the locking mechanism and elastic member, so that when engaged with the base, the coupling is automatically secured without requiring additional assembly steps. The limiting portion and locking portion are pre-positioned to ensure proper alignment and engagement.
Solution Approach 2:
The elastic member automatically returns the locking portion to the locked position after engagement, and the limiting portion self-aligns with the base during assembly. This self-servicing mechanism eliminates the need for manual adjustment or additional fastening steps, reducing assembly time while maintaining coupling strength.
3Ease of operation
If movable clasp mechanism is used for quick coupling, then the ease of operation is improved, but the coupling strength may deteriorate
Solution Approach 1:
The elastic member changes its force parameters based on the engagement state, providing strong holding force when locked and allowing easy release when the release mechanism is activated. The limiting portion changes its positional parameters to control the movement range of the locking portion, ensuring proper engagement depth for maximum coupling strength.
4Adaptability or versatility
If repeated coupling and separation is required, then the versatility is improved, but the reliability of the connection may deteriorate
Solution Approach 1:
The elastic member automatically returns the locking portion to the locked position after each engagement cycle, ensuring consistent coupling strength without manual intervention. This self-resetting mechanism maintains connection reliability across repeated coupling and separation operations.
Solution Approach 2:
The limiting portion recovers its original position after each engagement cycle, and the elastic member recovers its original shape and force. This recovery mechanism ensures that the fastening apparatus is ready for the next coupling operation, maintaining both versatility and reliability over repeated use.

AI summary
A fastening apparatus includes a base, a clasp body, and an elastic body. The base is configured to be arranged at a first object. The clasp body is movably disposed at the base, and movably couples or separates the second object. The elastic body is disposed between the base and the clasp body and pushes against the clasp body, such that the clasp body is normally located at an engaging connection position or normally located at a disengagement position. Thus, the base can be assembled with the first object and can be engaging connected with or disengaged from the second object using the clasp body, so as to complete quick coupling and separation of two objects, further achieving effects of repeated quick coupling and separation.
