Solution Overview

Problem

Conventional rotary switches require a reset button that occupies panel space and compromises sealing performance, making remote reset of a tripper in circuit breakers inefficient and inconvenient, especially in photovoltaic systems where remote switching is necessary.

Innovation Solution

A rotary operator with a handle, fastening base, and pressing component that allows for the tripper of a circuit breaker to be easily reset by sliding the pressing component relative to the fastening base, enabling contact or separation from the tripper, thereby facilitating remote reset without the need for a separate reset button.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a reset button is provided on the mounting panel to reset the tripper, then the tripper can be reset after switching operation, but panel space is occupied and sealing performance deteriorates

Engineering Contradiction:
Improvereset operationVSAvoidpanel space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent combines the reset function with the rotary operator itself by integrating a pressing component into the rotary operator structure. The pressing component can press the tripper reset button through the mounting panel without requiring a separate reset button hole, thus merging the reset function into the existing rotary operator assembly and eliminating additional panel openings.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rotary operator is designed to perform multiple functions: it can both rotate to control circuit breaker switching and simultaneously press the tripper reset button through its pressing component. This multi-functionality eliminates the need for separate reset mechanisms and panel openings dedicated solely to reset operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If a reset button is provided on the mounting panel to reset the tripper, then the tripper can be reset after switching operation, but sealing performance of the rotary switch and cabinet deteriorates

Engineering Contradiction:
Improvereset operationVSAvoidsealing performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The pressing component is integrated into the rotary operator structure and can press the tripper reset button through the mounting panel without creating additional sealing vulnerabilities. By reusing the existing rotary operator assembly rather than adding separate reset buttons with additional holes, the patent maintains the original sealing integrity while enabling reset functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If the pressing component is sleeved on the transmission end of the handle and slidably connected to the fastening base, then the tripper can be reset without occupying panel space, but the structure becomes more complex

Engineering Contradiction:
Improvepanel spaceVSAvoidrotary operator structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The rotary operator is segmented into distinct functional components: a handle for rotation, a transmission end for force transfer, and a pressing component for tripper reset. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural organization and manageability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pressing component is designed with slidable connection to the fastening base, allowing it to move dynamically between pressed and unpressed positions. This dynamic design enables the pressing component to engage the tripper reset button only when needed while remaining integrated with the rotary operator structure, balancing functionality with structural simplicity.

Inventive Principle:
Principle #15Dynamics

AI summary

A rotary operator and a rotary switch are disclosed, relating to the technical field of switches. The rotary operator includes a handle, a fastening base, and a pressing component. The fastening base is provided with an accommodation cavity. A transmission end of the handle is inserted in the accommodation cavity and is capable of relatively rotating in the accommodation cavity. The pressing component is sleeved on the transmission end of the handle and is slidably connected to the fastening base. The handle is pushed to move along an axis of the accommodation cavity, so that the pressing component moves relative to the fastening base to be in contact with or be separated from a tripper of a circuit breaker. The rotary operator can reset the tripper of the circuit breaker easily after a switching operation is completed.
