Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Arc accidents in distribution boards are difficult to recognize and manage, as existing arc eliminators lack a clear indication of their operational state, leading to potential power disruptions and safety risks.
Innovation Solution
An arc eliminator with a movable rod and an indicator mechanism that visually indicates the opening or closing state through a rotating indicator, allowing for easy external recognition without the need for a power source, reducing power consumption and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a mechanical indicator mechanism is used to indicate the operational state, then the ease of detecting and measuring the state is improved, but the device complexity increases
Solution Approach 1:
A mechanical indicator mechanism serves as an intermediary between the movable rod's operational state and the external observer. The indicator rotates to display different states (open/closed) visually, mediating the transmission of state information without requiring complex electronic systems or direct observation of internal components.
Solution Approach 2:
The patent replaces potential electronic indication systems with a purely mechanical indicator mechanism. The indicator is driven mechanically by the movable rod's motion, eliminating the need for motors, sensors, or power sources, thereby simplifying the overall system while maintaining clear state visibility.
2Reliability
If an indicator mechanism is added to show operational state, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The indicator mechanism is designed to be self-driven by the movable rod's own motion during operation. As the movable rod moves between open and closed positions, it directly or indirectly rotates the indicator through mechanical linkage, eliminating the need for separate power sources, actuators, or control systems. This self-service approach enhances reliability by reducing failure points while adding minimal complexity.
3Use of energy by moving object
If a mechanical indicator mechanism is used instead of an electronic system, then the use of energy is reduced, but the device complexity increases
Solution Approach 1:
The patent substitutes electronic indication systems with a mechanical indicator mechanism that operates entirely through mechanical energy transfer from the movable rod's motion. This eliminates the need for motors, batteries, or electrical power sources, achieving zero power consumption for the indication function while maintaining a relatively simple structural design through direct mechanical coupling.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables straightforward identification of the arc eliminator's state, minimizing arc accidents and reducing power consumption by using a mechanical indicator mechanism that operates without a motor, thus enhancing safety and efficiency.
Implementation Method 1
an indicator rotating mechanism interworking with the moving rod when the moving rod moves, to rotate the indicator
Data Source
AI summary
An arc eliminator includes a housing having a space formed therein and including an opening, an arc extinguishing part installed in the housing and including a moving rod disposed to be movable to the space, an indicator rotatably installed within the housing and seen through the opening, and an indicator rotating mechanism interworking with the moving rod when the moving rod moves, to rotate the indicator. A closing state and opening state of an arc extinguishing part may be easily recognized through an indicator and an arc accident may be minimized.
