Optic Support with Biasing Member for Light Fixture Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optic supports for light fixtures lack effective mechanisms to securely couple and seal optics like lenses to the housing, leading to potential dust, water, and particle ingress.
Innovation Solution
The use of a biasing member, such as a leaf spring, coupled to the optic support, which engages with the housing's internal surfaces to securely retain the lens and create a seal by pressing it against gaskets, preventing external particles from entering the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing optic supports are used without effective coupling mechanisms, then the device complexity is reduced, but the reliability deteriorates due to potential dust, water, and particle ingress
Solution Approach 1:
The patent combines the optic support function with the sealing function into a single integrated structure. The optic support is designed to both hold the lens in place and create a seal against the housing, eliminating the need for separate sealing components while maintaining reliable protection against dust and water ingress.
Solution Approach 2:
The optic support structure is designed to perform multiple functions simultaneously: mechanical support for the lens, sealing against the housing, and providing a mounting interface. This multi-functional design improves reliability without proportionally increasing device complexity, as one component accomplishes what would otherwise require multiple separate elements.
2Reliability
If a biasing member is added to securely couple the optic support, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The biasing member is designed to automatically apply sealing force and secure the optic support to the housing without requiring additional actuators or complex adjustment mechanisms. The spring-loaded or弹性 biasing structure self-regulates to maintain optimal contact pressure, providing reliable coupling while keeping the overall system simple through self-service functionality.
3Object-affected harmful factors
If the optic support presses the lens against gaskets to create a seal, then the protection against particles is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The optic support incorporates a dynamic biasing mechanism that automatically adjusts the sealing pressure based on assembly conditions and thermal expansion. This dynamic adjustment ensures consistent sealing performance without requiring precision pre-adjustment during manufacturing, thereby improving particle protection while maintaining ease of manufacture through self-adjusting functionality.
