Elevator Maintenance Push-Button Panel With Integrated LED Inspection Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control push-button panels for elevator maintenance operations lack sufficient lighting to reliably inspect the elevator shaft and pit, making it difficult for maintenance personnel to ensure safety and visibility, especially in poorly lit or humid environments.
Innovation Solution
A control push-button panel with a prismatic body featuring a hollow second portion that houses LED lighting components, which are hermetically integrated and powered by the panel's switches, providing high visibility and resistance to water and dust, allowing the light source to be moved closer to inspection areas and used as a portable torch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If small-size lamps are arranged on the control push-button panel to indicate activation status, then the panel can show whether push-buttons have been depressed, but the lighting is insufficient to illuminate the elevator shaft and pit for inspection
Solution Approach 1:
The patent combines the control push-button panel with a high-intensity lighting system into a single integrated device. The panel housing contains both the control elements and the lighting member with high-power LED, merging the functions of control and illumination into one portable unit that can be moved to different inspection locations.
Solution Approach 2:
The control panel is designed to serve multiple functions: it acts as both a control device for elevator operations and as a portable lighting source for inspection. The lighting member can be used to illuminate the elevator shaft, pit, and surrounding areas, making the panel a multi-functional tool for maintenance personnel.
2Reliability
If high-power LED lighting is integrated into the control panel, then the elevator shaft and pit can be properly illuminated for inspection, but the panel becomes more complex and requires hermetic integration
Solution Approach 1:
The patent employs a hermetic seal or protective barrier within the panel housing to enclose the lighting member and its electrical connections. This creates a protected environment that prevents water and dust ingress while maintaining the functionality of the high-power LED lighting system in harsh elevator pit conditions.
3Illumination intensity
If emergency lights and elevator bottom lighting are used, then some illumination is provided, but the capability to light the elevator shaft and pit for thorough inspection remains poor
Solution Approach 1:
The lighting system is designed as a portable, movable unit that can be dynamically positioned by the operator to different locations within the elevator shaft and pit. Unlike fixed emergency lights, this integrated panel can be moved closer to specific inspection areas, providing dynamic lighting that adapts to the operator's needs.
