Light Blade Fixture In-Place Component Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blade type light fixtures require total removal from their mounting surface for maintenance or repair, making it inconvenient to change or replace components like the PCB, driver, or lens.
Innovation Solution
A system and method allowing the PCB, driver, and lens to be replaced without removing the fixture from its mounting surface, by attaching a power supply to the upper housing, connecting cables, and using fasteners to detach and reattach the lower housing, enabling easy access and replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the fixture is designed as a single integrated unit, then the structural integrity and simplicity are improved, but the ease of repair and component replacement deteriorates
Solution Approach 1:
The fixture is divided into three main segments: upper housing (containing driver), lower housing (containing PCB and LEDs), and lens assembly. Each segment can be independently accessed, removed, or replaced while the fixture remains mounted, resolving the contradiction between repair ease and structural integrity
Solution Approach 2:
The patent implements a nested structure where the lower housing containing PCB and LEDs is inserted into the upper housing containing the driver. The lens assembly is nested within the lower housing. This nested design allows sequential access to components without complete disassembly, maintaining structural integrity while enabling easy repair
2Productivity
If the fixture requires total removal for maintenance, then the simplicity of maintenance procedure is improved, but the loss of time and productivity deteriorates
Solution Approach 1:
By segmenting the fixture into accessible modules (upper housing with driver, lower housing with PCB/LEDs, lens), maintenance personnel can service individual components in-place without removing the entire fixture, dramatically reducing downtime and improving productivity
Solution Approach 2:
The fixture is pre-configured with accessible fasteners, cable routing channels, and modular housing designs that enable quick component access. Power cables are routed through the upper housing with connectors positioned for easy disconnection, allowing maintenance to begin immediately without extensive preparation or fixture removal
3Ease of operation
If the fixture is made easily disassemblable, then the ease of operation for maintenance is improved, but the reliability and structural stability deteriorates
Solution Approach 1:
The fixture uses segmented housing design with distinct upper and lower sections connected by removable fasteners. This segmentation allows easy detachment for maintenance while maintaining structural integrity when assembled, as each segment is designed to be securely connected during normal operation
Solution Approach 2:
The fastening system transitions between two states: a locked state during operation providing structural stability, and an unlocked state during maintenance providing easy disassembly. The design allows dynamic switching between these states through simple fastener operations, maintaining reliability during use while enabling ease of operation during maintenance
