Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation assemblies are distributed at different sides of the isolation switch to enable diverse use scenarios, then the adaptability and ease of operation are improved, but the transmission member is prone to excessive movement and separation from the operation assembly, resulting in transmission failure and jamming
Solution Approach 1:
The patent introduces an elastic assembly that allows the transmission member to dynamically adjust its position. The elastic assembly can be compressed or extended to accommodate movement differences between multiple operation assemblies, preventing the transmission member from separating or jamming while maintaining synchronized operation across different sides of the isolation switch.
Solution Approach 2:
The elastic assembly acts as an intermediary between the transmission member and the operation assemblies. It mediates the force transmission while absorbing movement variations, ensuring that the transmission member remains engaged with the operation assemblies without excessive movement or separation, thus resolving the reliability issue while maintaining adaptability.
2Ease of operation
If the transmission member is used to synchronize multiple operation assemblies, then the ease of operation is improved, but the transmission member moves excessively and separates from the operation assembly, causing transmission failure
Solution Approach 1:
The elastic assembly provides dynamic compliance to the transmission system. When operation assemblies are actuated, the elastic assembly compresses or extends to accommodate the movement, ensuring continuous engagement of the transmission member without excessive movement or separation. This maintains ease of operation while preventing transmission failure.
Solution Approach 2:
The elastic assembly is pre-configured to provide cushioning force that prevents the transmission member from moving excessively. By having the elastic assembly ready to absorb movement variations before they cause separation or jamming, the system maintains reliable transmission engagement while allowing easy operation.
3Ease of operation
If operation assemblies are positioned at multiple sides for flexible operation, then the ease of operation is improved, but the transmission member is prone to jamming and transmission failure
Solution Approach 1:
The elastic assembly introduces dynamic flexibility to the transmission system, allowing it to adapt to operation inputs from multiple sides without requiring complex control mechanisms. The elastic assembly automatically adjusts to maintain proper transmission engagement, simplifying the overall control complexity while enabling multi-side operation.
Solution Approach 2:
The elastic assembly provides self-adjusting capability to the transmission system. When operation assemblies are actuated from different sides, the elastic assembly automatically compensates for movement variations to maintain engagement of the transmission member, eliminating the need for complex external control mechanisms and reducing device complexity.

AI summary
Provided in the present application are an operation mechanism capable of being operated at multiple sides, an isolation switch and a switch appliance, relating to the technical field of low-voltage appliances. A user can perform corresponding operation on the operation mechanism capable of being operated at multiple sides on different sides of the isolation switch, so as to achieve switching-on and switching-off control of the isolation switch. On the basis, each operation assembly in the operation mechanism capable of being operated at multiple sides can keep a stable and reliable transmission relationship with a transmission part, and then the problem of transmission failure or even jamming caused by the fact that the transmission part moves excessively and is separated from the operation assembly is avoided.
