Integrated Lighting Device for Vehicle Lifts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices lack adequate workspace illumination and clear indication of operating states, compromising worker safety and requiring separate lighting systems that increase complexity and costs.
Innovation Solution
Integration of a single lighting device providing both workspace lighting and operating status display lighting, controlled by a central device, using LED lights with adjustable geometry and color to indicate different operational states, along with an energy storage system for self-sufficiency, and optional acoustic signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate lighting systems are used for workspace illumination and operating status display, then each function can be optimized independently, but device complexity and costs increase
Solution Approach 1:
The patent combines workspace lighting and operating status display lighting into a single integrated lighting device. The lighting device includes a housing with a light source that can emit different colors (e.g., white for workspace lighting, red/yellow/green for operating status indicators). This merging eliminates the need for separate lighting systems while maintaining both functions, thereby reducing device complexity and costs without compromising workspace safety
Solution Approach 2:
The lighting device is designed to perform multiple functions: it provides workspace illumination and simultaneously displays operating status information through color-coded signals. The single device serves as both a general lighting source and a visual indicator system, making the lighting system universal and multi-functional rather than requiring specialized separate systems for each purpose
2Ease of operation
If multiple separate lighting devices are installed for workspace lighting and status indication, then functional requirements are met, but production costs and installation complexity increase
Solution Approach 1:
By merging workspace lighting and status indication into one device, the patent reduces the number of components that need to be manufactured, stored, and installed. The single lighting device with multi-color capability is more cost-effective to produce than multiple separate devices, while still providing clear visual information to workers about operating status and workspace illumination
3Device complexity
If a single lighting device provides both workspace lighting and operating status display, then device complexity and costs are reduced, but the lighting device must perform multiple functions simultaneously
Solution Approach 1:
The lighting device is designed with universal functionality to handle both workspace illumination and operating status display through a single light source that can emit different colors. This multi-functional design allows the device to adapt to different operational states (e.g., powered on, powered off, fault conditions) while maintaining structural simplicity and avoiding the need for multiple specialized devices
