Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lighting solutions for wet locations, such as agricultural barns, often require complex installations and are not easily adaptable to existing incandescent fixtures, lacking efficient watertight and tool-less connection methods.
Innovation Solution
A modular LED lighting system featuring a fluidically-sealed light component with a heat sink, fan, and O-ring sealed junction box that can be retrofitted into existing sockets without screws or connectors, using a twist-and-lock mechanism for easy installation and watertight sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional incandescent fixtures with threaded glass jars are used, then watertight sealing is achieved, but installation complexity and time increase due to screw connections and multiple components
Solution Approach 1:
The patent combines the jar, lid, and sealing mechanism into a single integrated LED light unit that twists directly into the socket. This merging eliminates the need for separate glass jars, lids, and screw connections, achieving both watertight sealing and tool-less installation.
Solution Approach 2:
The LED light unit is designed as a universal replacement that combines multiple functions: it serves as the light source, the watertight enclosure, and the installation mechanism all in one component. This single unit can replace various existing fixture types without requiring separate components for each function.
2Adaptability or versatility
If multiple enclosure sizes are used to fit different fixture types, then adaptability to existing fixtures is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The patent designs a single universal LED light unit that can be installed in various existing fixture types (Edison sockets, junction boxes, etc.) without requiring different enclosure sizes. The unit's standardized threading and compact design enable it to adapt to multiple fixture configurations while maintaining a single product design.
Solution Approach 2:
The LED light unit is designed as a modular component that can be independently installed in different fixture environments. Its segmented design allows it to function as a complete replacement unit in various socket types and enclosure configurations without requiring the enclosure itself to change sizes.
3Productivity
If tool-less twist and lock mechanism is implemented, then installation speed and ease are improved, but connection reliability and watertight sealing may be compromised
Solution Approach 1:
The twist-lock mechanism is designed to be self-sealing and self-locking. As the LED unit is twisted into the socket, the O-ring seal is automatically compressed and locked into position, creating a watertight connection without requiring additional tools or steps. The mechanical action of twisting simultaneously achieves both mechanical connection and sealing.
Solution Approach 2:
The patent uses material properties and geometric design to ensure that the twist-lock action automatically achieves the required sealing pressure. The O-ring material and groove geometry are designed so that the twisting motion naturally compresses the seal to the optimal degree, transforming the installation action into both connection and sealing functions.
