Automatic Arc Reduction Actuator for Electrical Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical systems require manual actuation of arc reduction assemblies, leading to potential damage during maintenance due to failure in enabling the technology, necessitating an automatic and passive actuation mechanism.
Innovation Solution
An automatic actuator assembly comprising a passive actuator and detection system that moves the arc reduction assembly between disengaged and engaged configurations based on proximity communication, such as user presence or housing door movement, ensuring the arc reduction assembly is engaged without user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual actuation of arc reduction assembly is used, then device complexity is reduced, but reliability deteriorates due to user failure to enable protection
Solution Approach 1:
The arc reduction assembly actuates itself automatically through the passive actuator assembly when the detection assembly senses user proximity or door opening, eliminating the need for manual user action and ensuring reliable activation without adding complex control systems
Solution Approach 2:
The patent replaces manual mechanical actuation with an automatic system using detection assembly (sensors) and passive actuator assembly (mechanical linkage), substituting human operation with an automated sensing and response mechanism
2Reliability
If automatic actuator assembly is added, then reliability of arc reduction activation is improved, but device complexity increases
Solution Approach 1:
The automatic actuator assembly is divided into separate functional modules: detection assembly (sensors) and passive actuator assembly (mechanical linkage), allowing independent optimization and simplified integration into the existing arc reduction system
Solution Approach 2:
The passive actuator assembly serves as an intermediary mechanical component that translates detection signals into physical actuation of the arc reduction assembly, bridging the sensing and protection functions without requiring complex control electronics
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Automatically engages the arc reduction assembly when a user is near or accessing the electrical system, enhancing safety and reducing equipment damage by eliminating the need for manual activation.
Implementation Method 1
The detection assembly is structured to detect at least one of the presence of a user adjacent a housing assembly or movement of a housing assembly door. The detection assembly is further structured to provide a proximity communication to the passive actuator assembly.
