Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple lanyard connection is used, then the device structure is simple, but the hanging object is prone to fall off and replacement is inconvenient
Solution Approach 1:
The locking device is divided into distinct functional components: a locking member with groove, a resilient member, and a hanging member with protrusion. This segmentation allows each component to perform its specific function while maintaining overall structural simplicity and secure attachment.
Solution Approach 2:
The locking member's groove is pre-configured to receive and retain the hanging member's protrusion through gravitational engagement. This preliminary configuration prevents accidental detachment by requiring deliberate upward force to disengage, thus providing security before any release action occurs.
2Reliability
If a secure locking mechanism is implemented, then the hanging object is securely attached, but the operation and replacement become more complex
Solution Approach 1:
The resilient member is pre-loaded to exert continuous elastic force on the hanging member, maintaining it in a locked position within the groove. This preliminary action ensures secure attachment while allowing simple release by overcoming the elastic force, making operation convenient.
Solution Approach 2:
The resilient member provides dynamic elastic force that automatically adjusts to maintain the locked state. When the hanging member is inserted, the resilient member dynamically engages it into the groove; when release is needed, the same elastic force can be easily overcome, enabling simple operation.
3Ease of operation
If a resilient member is added to improve ease of operation, then the replacement becomes easier, but the device complexity increases
Solution Approach 1:
The resilient member serves multiple functions simultaneously: it provides the locking force to secure the hanging member in the groove, enables easy release by storing elastic energy that can be easily overcome, and acts as a shock absorber. This multi-functionality justifies its inclusion despite adding one component.
Solution Approach 2:
The resilient member automatically performs the locking and unlocking functions without requiring additional mechanisms or complex operations. It self-regulates the engagement and disengagement of the hanging member through its elastic properties, making the system self-sufficient.

AI summary
A locking device includes a sleeve, an actuator, and a stopper. The sleeve defines a receiving cavity and an outlet communicating with the receiving cavity. An inner wall of the receiving cavity defines a sliding groove and a stopping groove. The actuator is provided in the receiving cavity. One end of the actuator is inserted in the outlet, and another end of the actuator extends out of the receiving cavity. The stopper is provided on the actuator. The actuator is configured to be rotated to switch the stopper between the sliding groove and the stopping groove. When the stopper resists in the stopping groove, the actuator is fixed in the sleeve. When the stopper is switched to the sliding groove, the actuator is pressed to slide along the sliding groove and extend out of the outlet.
