Emergency Lighting Converter Interface Using Switch Pins for Log Readout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency lighting converters lack an efficient method to access internal log data storage without physically opening the housing, making data reading cumbersome and costly.
Innovation Solution
The emergency lighting converter uses existing connecting elements for both test switch and status indicator light interfaces to also facilitate data communication, eliminating the need for additional connectors and allowing external access to the log data memory without opening the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional connectors are added for log data access, then data accessibility is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies multi-functionality by enabling existing connecting elements (designed for test switch and status indicator light interfaces) to serve dual purposes: their original functions plus log data communication. The connecting elements are configured to provide both electrical connections for control functions and data transmission paths for log access, eliminating the need for separate dedicated connectors.
Solution Approach 2:
The patent merges the log data communication function with existing control interfaces. The data transmit and data receive connections are integrated into the same connecting elements that handle test switch signals and status indicator light signals, combining multiple functions into unified interface structures.
2Ease of operation
If housing is opened for data access, then direct memory access is enabled, but ease of operation deteriorates and time loss increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring the connecting elements with dual functionality during manufacturing. The connecting elements are designed and assembled to provide both control signal paths and log data communication paths from the outset, so that log data accessibility is immediately available through existing interfaces without requiring subsequent housing opening or reconfiguration.
3Ease of manufacture
If existing interfaces are used for data communication, then manufacturing cost is reduced, but interface functionality complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling existing connecting elements (designed for test switch and status indicator light interfaces) to serve dual purposes: their original functions plus log data communication. The connecting elements are configured to provide both electrical connections for control functions and data transmission paths for log access, eliminating the need for separate dedicated connectors.
