Isolating Switch Dual Energy Storage for Larger Output Shaft Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing single energy storage mechanism in isolating switches limits the rotation angle of the output shaft, resulting in insufficient opening when in the switching-off position, affecting electrical and mechanical performances.
Innovation Solution
A dual energy storage mechanism is introduced, comprising a first energy storage mechanism between the input wheel and the housing, and a second energy storage mechanism between the input wheel and the output wheel or output shaft, with a limiting mechanism that allows simultaneous energy storage and release, enhancing the rotation angle and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single energy storage mechanism is used, then the structure is simple, but the rotation angle of the output shaft is limited and insufficient opening occurs
Solution Approach 1:
The patent divides the single energy storage mechanism into two separate energy storage mechanisms (first and second). The first energy storage mechanism is connected between the input wheel and housing, while the second energy storage mechanism is connected between the input wheel and output wheel. This segmentation allows each mechanism to contribute independently to the rotation angle, thereby increasing the total rotation angle without significantly complicating the overall structure.
2Length of moving object
If a dual energy storage mechanism is introduced, then the rotation angle of the output shaft is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges the functions of two energy storage mechanisms into a single integrated system. Both the first and second energy storage mechanisms are driven by the same input wheel, and their combined energy release is coordinated through the limiting mechanism to produce a unified rotational output. This merging approach maximizes the rotation angle while minimizing the increase in complexity by sharing common components and control structures.
Solution Approach 2:
The limiting mechanism serves as an intermediary between the two energy storage mechanisms and the output wheel. It controls the release of energy from both mechanisms, ensuring they work in coordination rather than independently. This intermediary component manages the complexity by providing a single point of control for the dual mechanisms, thereby enhancing the rotation angle without proportionally increasing the overall system complexity.
3Stability of the object's composition
If the energy storage mechanism releases limited energy, then the structure is stable, but the opening becomes insufficient in switching-off position
Solution Approach 1:
The patent employs preliminary action by having the first and second energy storage mechanisms store energy in advance during the switching-on position. The input wheel, driven by the operating handle, winds both spring mechanisms before the switching-off operation. This preliminary energy storage ensures that when switching-off is required, both mechanisms can release their stored energy simultaneously or sequentially to provide sufficient opening force, thereby improving ease of operation while maintaining structural stability through pre-planned energy accumulation.

AI summary
A dual energy storage operating mechanism of an isolating switch is provided. A first energy storage mechanism and a second energy storage mechanism are provided between an input wheel and a housing and between the input wheel and an output wheel or a first output shaft, respectively. The output wheel is provided with a limiting mechanism. The limiting mechanism forms a locking effect on the output wheel when the first energy storage mechanism stores energy, thereby enabling the second energy storage mechanism to store energy at the same time. When the first energy storage mechanism starts to release energy, the locking effect of the limiting mechanism is released, so that the output wheel and the first output shaft can rotate, and the first energy storage mechanism and the second energy storage mechanism release energy at the same time, forming a dual energy storage boosting effect.
