Remote Control Unit With Detachable Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control units for sink drain valves often lack reliable closure due to the mechanism returning to its initial position, and maintenance is complex, requiring replacement of the entire unit when damaged, which is costly and inconvenient for retrofitting.
Innovation Solution
A remote control unit with a detachable locking mechanism that allows for easy maintenance and retrofitting, featuring a latching mechanism with defined locking positions and a flexible Bowden cable for improved reliability and ease of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a firmly connected switching device with a latching mechanism is integrated into the force transmission element, then functional reliability is improved, but ease of repair deteriorates because the entire remote control unit must be replaced
Solution Approach 1:
The remote control unit is segmented into separate functional components: the force transmission element (Bowden cable) and the switching device with latching mechanism. This segmentation allows the switching device to be replaced independently without replacing the entire remote control unit, resolving the contradiction between improved reliability and ease of repair.
2Reliability
If the entire remote control unit is replaced when damaged, then reliability is maintained, but loss of time and cost increase due to complex and expensive replacement procedures
Solution Approach 1:
By segmenting the remote control unit into replaceable components, particularly the switching device, the patent enables targeted replacement of only the defective part rather than the entire unit, significantly reducing replacement time and cost while maintaining reliability.
Solution Approach 2:
The patent enables selective discarding of only the defective switching device component while recovering and retaining the functional force transmission element (Bowden cable), reducing waste and replacement costs while ensuring reliability through replacement of the faulty component.
3Stability of the object's composition
If a fixed connection is used between the force transmission element and switching device, then structural stability is improved, but adaptability deteriorates for retrofitting applications
Solution Approach 1:
The segmented design allows the switching device to be detached and adapted to different force transmission elements or installation locations, providing retrofitting flexibility while maintaining structural stability through proper connection interfaces.
Solution Approach 2:
The switching device is designed as a universal component that can be adapted to work with different force transmission elements and installation configurations, enabling retrofitting applications while maintaining structural stability through standardized connection mechanisms.
