Safety Switch with Integrated Light for Emergency Equipment Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency lighting systems require separate components for testing battery backup systems, which are inefficient, prone to vandalism, and difficult to inspect, especially in smoke-filled environments where visibility is compromised.
Innovation Solution
A safety switch with an integrated light that replaces the test push switch, utilizing a push momentary switch, LED bezel light source, and switch logic circuit with AC to DC converter, microprocessor, and monitoring device to provide a single, efficient, and visible testing mechanism for AC voltage and battery backup functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate test push switch and light indicator are used, then testing functionality is achieved, but device complexity increases and vulnerability to vandalism increases
Solution Approach 1:
The patent combines the test push switch and light indicator into a single integrated safety switch assembly. The momentary push button switch is housed within the same bezel as the light emitting diode, creating one unified component that performs both testing and indication functions. This eliminates the need for separate test switches and light indicators, thereby reducing device complexity while maintaining full testing functionality.
Solution Approach 2:
The integrated safety switch assembly serves multiple functions: it acts as both a test initiation mechanism and a power status indicator. The same housing and mounting structure support both the push button switch for initiating battery tests and the LED for displaying AC power presence. This multi-functional design reduces the number of separate components needed in the emergency lighting system.
2Reliability
If separate test push switch and light indicator are used, then testing functionality is achieved, but ease of operation deteriorates due to difficulty in smoke-filled environments
Solution Approach 1:
The patent utilizes the light emitting diode to provide visual feedback through light emission. The LED serves as a clear visual indicator of AC power presence, making it easily distinguishable in smoke-filled environments during emergencies. The integrated design ensures that both the test button and light indicator are positioned together, allowing operators to quickly locate and interact with the controls even when visibility is compromised.
3Reliability
If protruding test push button is used, then testing functionality is achieved, but object-generated harmful factors increase due to vandalism
Solution Approach 1:
The patent integrates the push button switch within the same bezel structure that houses the light emitting diode. This unified assembly is mounted on the emergency lighting fixture housing, creating a single protected enclosure. The integration reduces the number of separate accessible components that could be targeted for vandalism, while the sturdy bezel structure provides physical protection for both the switch and light elements.
