Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly structures for light-guiding covers in LED lighting devices, such as street lamps, are cumbersome and hazardous due to the need for aerial assembly and detachment, which increases the time and risk involved in replacing these covers.
Innovation Solution
A rapid assembly structure for light-guiding covers using a casing with engaging grooves and sheets that allow for tool-free engagement and disengagement, reducing the complexity and danger of the process, and incorporating elastic properties to secure the cover in place without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a light-guiding cover is assembled using conventional methods in aerial position, then the lighting device can be installed, but the difficulty and danger of assembly increase significantly
Solution Approach 1:
The light-guiding cover is divided into modular components that can be assembled separately on the ground, then quickly installed as a unit. The cover includes segmented structures with engaging sheets that allow for simplified assembly operations.
Solution Approach 2:
The engaging sheets are designed to automatically engage with corresponding grooves on the casing without requiring external tools or complex assembly procedures. The elastic material of the engaging sheets enables self-latching functionality.
2Productivity
If conventional assembly methods are used for light-guiding covers, then structural stability is achieved, but the time required for assembly and replacement increases
Solution Approach 1:
The engaging sheets are pre-positioned on the light-guiding cover during manufacturing, so that during installation, only the simple action of aligning and pressing the cover onto the casing is required. The preliminary preparation of engagement structures eliminates the need for complex on-site assembly procedures.
Solution Approach 2:
Traditional mechanical fastening systems (screws, bolts, or multiple manual steps) are replaced with an elastic engagement system where the engaging sheets utilize elastic deformation to create a snap-fit connection, dramatically reducing assembly time.
3Ease of operation
If aerial assembly is performed for light-guiding covers, then the lighting device can be installed at height, but safety risks and operational difficulty increase
Solution Approach 1:
The assembly process is segmented into ground-based preparation and aerial installation phases. All complex manipulation is performed on the ground, and only the simple attachment of the pre-assembled cover is required at height, reducing safety risks.
Solution Approach 2:
The self-engaging design allows the cover to secure itself to the casing through automatic engagement of the elastic sheets with the grooves, eliminating the need for manual fastening operations at height and reducing safety concerns.
