Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED lamp production is hindered by the need for manual assembly due to the requirement of gluing or using fasteners, which complicates automation.
Innovation Solution
A lamp design featuring a metal lamp holder with an installation cavity and a plastic or nylon end cover with a convex interference fit, allowing for a plug-in connection that facilitates automated assembly, with a guide block and groove system for alignment and a U-shaped cross-section for easy manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If gluing or fasteners are used to connect parts, then connection strength is improved, but manufacturing complexity increases and automation becomes difficult
Solution Approach 1:
The lamp holder is divided into multiple modular sections (first lamp holder section, second lamp holder section, end cap) that can be independently manufactured and then assembled through simple plug-in operations, reducing overall manufacturing complexity while maintaining connection strength
Solution Approach 2:
The connection structure integrates the fixing hole, convex portion, and guide groove into a unified plug-in mechanism that combines alignment and fixation functions, eliminating the need for separate gluing or fastening operations
2Manufacturing precision
If manual assembly is used, then connection precision is improved, but production efficiency decreases
Solution Approach 1:
The guide groove and convex portion are pre-formed during manufacturing, establishing precise alignment features before assembly. This preliminary preparation enables automated systems to achieve high precision connections without manual intervention
Solution Approach 2:
The plug-in structure with guide groove and convex portion enables self-alignment and self-fixation during assembly. The components automatically find their correct positions and secure themselves, eliminating the need for manual positioning and adjustment
3Extent of automation
If plug-in fitting is used for end cover and lamp holder, then automation is improved, but connection reliability may decrease
Solution Approach 1:
The connection structure uses a combination of metal lamp holder and plastic/nylon end cap materials. The material complementarity provides both the precision needed for automated plug-in assembly and the mechanical strength for reliable connections, with the harder metal providing structural integrity and the softer plastic providing friction-based locking
