Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a motor-driven mechanism is used to control the rotary switch, then the switching function can be achieved, but the response time becomes slow and the device size becomes large
Solution Approach 1:
The patent extracts and removes the motor component from the switching mechanism, replacing it with a spring-driven release mechanism. This eliminates the complex motor structure while achieving rapid switching through the energy storage and release of the spring system, directly resolving the contradiction between switching speed and device complexity
Solution Approach 2:
The spring is pre-loaded and energized before the switching event occurs. The energy storage spring is compressed or twisted in advance, storing potential energy that is rapidly converted to kinetic energy when the release mechanism is triggered, enabling fast response without requiring a motor during the actual switching action
2Extent of automation
If a motor-driven mechanism is used to control the rotary switch, then the switching function can be achieved, but the device cost becomes high
Solution Approach 1:
The patent replaces the expensive motor component with a simple, inexpensive spring mechanism and release component. These mechanical parts are much cheaper to manufacture and assemble, while still providing the required automated remote switching function through the tripping mechanism that releases the stored spring energy
Solution Approach 2:
The patent substitutes the electromechanical motor system with a purely mechanical spring-driven system. This replacement eliminates the need for electrical motors, power supplies, and control circuits, significantly reducing manufacturing costs while maintaining the automated switching capability through mechanical energy storage and release
3Speed
If a motor-driven mechanism is used to control the rotary switch, then the switching function can be achieved, but the device size becomes large
Solution Approach 1:
The patent employs a dynamic spring mechanism that can store and rapidly release energy, enabling fast switching in a compact form. The spring system provides the necessary force and speed for switching without requiring the bulky motor structure, achieving both high speed and small size through dynamic mechanical energy storage and release

AI summary
The present invention discloses a remote switch-off mechanism and a rotary switch, and relates to the field of electrical technologies. A housing, an energy storage component, and a tripping component are provided. The energy storage component includes a latch, an energy storage spring, a rotating shaft, and an energy storage panel connected to the rotating shaft, an abutting portion is disposed on the energy storage panel, a first end of the energy storage spring is clamped to the housing, and a second end of the energy storage spring abuts against the abutting portion. The latch includes a hinged portion hinged to the housing, a limiting portion for limiting the second end of the energy storage spring, and a tripping portion that cooperates with the tripping component, and an elastic member is disposed between the latch and the housing, so that the tripping portion has a trend of moving toward the tripping component. The tripping component is configured to enable the limiting portion to release limiting on the second end of the energy storage spring, so that the rotating shaft rotates to a switch-off position. According to the remote switch-off mechanism and the rotary switch in this application, response time during switching of the rotary switch can be improved.
