Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting solutions for wet locations, such as agricultural barns, often require cumbersome and inefficient installation methods, and lack the ability to seamlessly integrate with existing fixtures, particularly in terms of watertight seals and tool-less assembly.
Innovation Solution
A modular LED lighting system that includes a fluidically-sealed LED lamp capable of being retrofitted into existing Edison socket fixtures, featuring a twist and lock mechanism for tool-less installation and a junction box with an embedded O-ring for a watertight seal, allowing for efficient and secure installation in wet locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional threaded glass jar fixtures are used in wet locations, then watertight sealing is achieved, but installation becomes cumbersome and time-consuming
Solution Approach 1:
The lighting assembly is divided into separate modular components including a base portion with external threading, a jar portion with internal threading, and an LED light source module. This segmentation allows pre-assembly of watertight components at the factory while enabling rapid field installation by simply screwing the modular sections together, resolving the contradiction between achieving reliable watertight seals and reducing installation time
Solution Approach 2:
The watertight sealing components, including gaskets and O-rings, are pre-installed on the jar portion during manufacturing before the product reaches the installation site. This preliminary action ensures that when the fixture is installed in wet locations, the watertight seal is already in place and functional, eliminating the need for complex sealing procedures during installation and thereby reducing installation time while maintaining reliability
2Use of energy by moving object
If LED lighting is integrated into existing fixtures, then energy efficiency improves, but compatibility with existing socket fixtures becomes limited
Solution Approach 1:
The base portion of the lighting assembly is designed with external threading that universally fits into existing Edison socket fixtures and other standard mounting locations. The LED light source module can be configured to accept various bulb types and socket configurations. This universal design enables the energy-efficient LED technology to be integrated into diverse existing fixtures without requiring fixture replacement, thereby maintaining high adaptability while achieving improved energy efficiency
3Productivity
If modular components are used for LED lighting, then installation efficiency improves, but the number of parts and assembly complexity increases
Solution Approach 1:
The modular components are designed to combine into a single integrated lighting assembly through simple threaded connections. The base portion, jar portion, and LED module merge together to form a complete fixture that functions as a unified system. This merging approach allows the benefits of modular installation efficiency while minimizing the perceived complexity, as the components are few in number and connect through straightforward mechanical interfaces rather than complex assembly procedures
