Multi-button Waterway Switching Mechanism Synchronous Valve Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-button waterway switching mechanisms cannot drive two valve cores to slide synchronously, limiting simultaneous operation of water diversion channels.
Innovation Solution
A multi-button waterway switching mechanism with three buttons, where two first buttons are connected to valve cores and a second button is connected to a transmission member, allowing the two valve cores to slide synchronously through the transmission member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two valve cores are driven alternatively using existing switching mechanisms, then the structure is simple, but the two valve cores cannot be driven to slide synchronously at the same time
Solution Approach 1:
The transmission member is segmented with two separate abutting portions, where each portion can independently abut against a respective valve core. This segmentation allows the transmission member to transmit force to both valve cores simultaneously when the second button is pressed, enabling synchronous operation while maintaining a relatively simple overall structure.
Solution Approach 2:
The transmission member acts as an intermediary between the second button and the two valve cores. When the second button is pressed, the transmission member mediates the force transmission to both valve cores simultaneously, enabling synchronous operation without requiring direct connection between the button and both valve cores, thus avoiding excessive complexity.
2Ease of operation
If two first buttons are pressed at the same time to drive two valve cores, then synchronous sliding can be achieved, but it is inconvenient to press
Solution Approach 1:
The functions of two separate control buttons are merged into a single second button. When this single button is pressed, it drives the transmission member which simultaneously actuates both valve cores. This merging eliminates the need to press two buttons simultaneously, greatly improving operational convenience while maintaining the capability for synchronous valve core operation.
Solution Approach 2:
The second button is designed with multi-functionality: it can independently control the first valve core through direct connection, independently control the second valve core through the transmission member, and simultaneously control both valve cores through the transmission member. This universal control mechanism allows a single button to perform multiple functions, improving ease of operation.
