Disconnect Terminal Coupling Device for Switching Lever Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing isolating terminals require separate adjustment of switching levers, which is inconvenient and only possible when the connecting element is removed, lacking a simple and quick reversible switch connection with a compact structure and minimal components.
Innovation Solution
An arrangement comprising at least two isolating terminals with a coupling device that connects and separates switching levers in different coupling positions, allowing independent adjustment of each lever and providing a clear switching status display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If switching levers are connected using a fixed connecting element, then the switching levers can be operated together, but the connection cannot be easily changed and requires removal of the connecting element for separate adjustment
Solution Approach 1:
The coupling element is designed to be movable between a first coupling position (connecting the switching levers) and a second coupling position (releasing the switching levers). This dynamic design allows the connection state to be changed simply by moving the coupling element, enabling both joint operation and independent adjustment without permanent fixation or complex disassembly procedures.
2Productivity
If multiple disconnect terminals are operated independently, then each terminal can be adjusted separately, but quick joint operation of multiple terminals is not possible
Solution Approach 1:
The coupling device is designed to couple multiple switching levers simultaneously through a single coupling element that can engage with multiple levers. This allows all connected switching levers to be operated together in one motion, significantly increasing productivity when joint operation is needed, while the modular design maintains ease of independent adjustment when the coupling element is in the release position.
3Ease of operation
If a coupling device is added to allow quick connection, then joint operation becomes possible, but the compact structure and minimal components may be compromised
Solution Approach 1:
The coupling element is integrated with one of the switching levers, merging the coupling function into the existing lever structure rather than adding a completely separate coupling mechanism. This reduces the total number of components and maintains a compact structure while still providing reversible coupling capability. The coupling element utilizes the existing pivot mechanism of the switching levers, combining multiple functions into a unified design.
