Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional button operation mechanism is used to lock the transmission cable, then the cable can be secured to the socket, but the operation becomes difficult because the button is large compared with the user's fingers
Solution Approach 1:
The locking mechanism is segmented into multiple functional components: locking clips (first and second), a locking band, a tension stopper, and a handle. This segmentation allows each component to perform a specific function, with the handle providing leverage for easy operation while the clips provide secure locking. The segmented design resolves the contradiction by making the operation easy through the handle's mechanical advantage while maintaining security through the distributed locking clips.
Solution Approach 2:
The locking band acts as an intermediary element that connects the locking clips and transmits tension forces between them. This intermediary component allows the system to achieve secure locking without requiring a large button, as the locking band distributes the locking force across multiple clips. The tension stopper serves as another intermediary that controls the tension in the locking band, enabling easy operation through the handle while maintaining secure fixation.
2Reliability
If an outer spring is used to lock the transmission cable with a button, then the cable can be secured, but noise is generated during operations and play or backlash is formed between the locking button and the spring
Solution Approach 1:
The invention extracts and eliminates the outer spring from the locking mechanism, replacing it with a tension stopper and locking band system. This removal of the spring eliminates the source of noise generation and backlash while maintaining the secure locking function. The tension stopper provides controlled tension without the play and noise associated with spring-based mechanisms, directly resolving the contradiction between reliable fixation and noise reduction.
Solution Approach 2:
The invention replaces the expensive outer spring with simpler, more durable components including the tension stopper and locking band. These components are designed to be robust and long-lasting, eliminating the need for expensive spring elements that generate noise and require maintenance. The simplified components reduce cost while improving reliability by eliminating the harmful effects of spring-based mechanisms.
3Ease of operation
If an outer spring is used to lock the transmission cable, then the cable can be secured, but the operation becomes difficult and play or backlash is formed between the locking button and the spring
Solution Approach 1:
The locking mechanism incorporates dynamic elements including the rotatable locking clips and the tension stopper that responds to operational forces. The locking clips can rotate to engage and disengage from the socket, providing smooth operation without backlash. The tension stopper dynamically adjusts to maintain optimal tension in the locking band, ensuring reliable fixation while enabling easy operation. This dynamic design resolves the contradiction by allowing smooth, backlash-free operation while maintaining secure locking.
Solution Approach 2:
The locking band serves as an intermediary that transmits forces smoothly between the locking clips and the tension stopper, eliminating the play and backlash associated with spring-based mechanisms. This intermediary component ensures continuous, smooth force transmission during operation, making the mechanism easy to operate while maintaining reliable fixation. The tension stopper acts as another intermediary that controls the locking band's tension, ensuring both ease of operation and fixation stability.
