Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED lamps used in dusty or chemically reactive environments face issues with material buildup on the outer window, leading to reduced light intensity and uniformity, requiring manual scraping or chemical cleaning, which is time-consuming and can damage the window, and there is a need for a solution that allows easy replacement and monitoring of the window by non-technical personnel.
Innovation Solution
A novel LED lamp design featuring a replaceable window system with a hinged clamp for easy removal, integrated sensors, and a light pipe to detect material buildup on the outer window, allowing for real-time monitoring and notification of intensity and uniformity issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If manual scraping or chemical cleaning is used to remove material buildup on the outer window, then the light intensity and uniformity are restored, but the window may be permanently damaged or the system downtime is excessive
Solution Approach 1:
The patent incorporates sensors that continuously monitor the outer window surface for material buildup and provide feedback signals when cleaning is required. This automated detection system eliminates the need for manual inspection and enables timely maintenance before severe buildup occurs, restoring light intensity proactively while preventing window damage through non-contact monitoring.
Solution Approach 2:
The system performs self-monitoring through integrated sensors that automatically detect material buildup on the outer window. The sensor system serves itself by continuously assessing its own operational condition without external intervention, triggering maintenance alerts when cleaning is needed, thus maintaining light intensity through self-awareness of its state.
2Loss of time
If the outer window is made easily replaceable for quick maintenance, then the system downtime is reduced, but the securing mechanism becomes more complex
Solution Approach 1:
The patent divides the lamp assembly into separable modules, with the outer window designed as an independent replaceable component. This segmentation allows the window to be removed and replaced without affecting the rest of the lamp structure, enabling quick maintenance with minimal system downtime while keeping the securing mechanism relatively simple through modular design.
Solution Approach 2:
The outer window is extracted as a separate, independently replaceable component from the main lamp body. This extraction allows the window to be removed quickly for cleaning or replacement without disassembling the entire lamp, reducing system downtime while maintaining a straightforward securing mechanism through simple attachment and detachment interfaces.
3Illumination intensity
If sensors are integrated to monitor material buildup in real-time, then the light intensity and uniformity can be maintained, but the device complexity increases
Solution Approach 1:
The patent merges the sensing function directly into the lamp structure by integrating sensors that monitor the outer window surface. This consolidation combines the monitoring capability with the existing lamp components, enabling real-time detection of material buildup to maintain light intensity while minimizing additional complexity through integrated rather than separate sensor systems.
Solution Approach 2:
The sensor system is designed to perform multiple functions: detecting material buildup on the outer window, monitoring light intensity variations, and providing maintenance alerts. This multi-functionality allows a single sensor integration to address multiple operational parameters, maintaining light quality while reducing overall device complexity compared to separate specialized sensors for each function.
