In-Grade Light Fixture Modular Housing for Easy Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor light fixtures are often difficult to repair and maintain, especially in environments exposed to environmental hazards like moisture and dirt, due to their complex designs and the need for specialized technicians.
Innovation Solution
The design of an in-grade light assembly with an inner housing assembly that includes a body and a clamp configured to slide relative to the body, creating an interference fit with the inner surface of a structure, allowing for easy installation and removal, and facilitating repair by enabling the interchangeability of inner housing assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional outdoor light fixtures are designed with complex structures to ensure reliability in harsh environments, then the reliability improves, but the ease of repair deteriorates
Solution Approach 1:
The light fixture is divided into modular components: an outer housing, an inner housing assembly, and a removable light module. The inner housing assembly can be independently removed from the outer housing, and the light module can be replaced without removing the entire fixture. This segmentation enables easy repair and maintenance while maintaining system reliability through protected components.
2Stability of the object's composition
If light fixtures are designed with secure mounting mechanisms to remain stable in harsh environments, then the stability improves, but the ease of installation and removal deteriorates
Solution Approach 1:
The mounting mechanism transitions from a static fixed connection to a dynamic adjustable connection. The inner housing assembly includes mounting ears with slots that accommodate mounting pins, allowing the assembly to be easily inserted and removed while maintaining stable positioning when installed. The clamp mechanism provides adjustable securing force to ensure stability during operation while enabling simple installation and removal.
3Reliability
If specialized technicians are required to repair light fixtures in harsh environments, then the reliability of repair improves, but the loss of time and cost increases
Solution Approach 1:
The modular design with tool-free or minimal-tool replacement capabilities enables end-users to perform maintenance and repairs themselves without requiring specialized technicians. The light module can be easily removed and replaced by the user, and the inner housing assembly can be accessed and serviced with minimal technical expertise, reducing both time and cost while maintaining repair quality through standardized components.
