Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LED strip lights face issues with poor waterproofing due to structural design flaws, leading to inadequate protection against water and dust, which affects the service life and safety of the bulbs.
Innovation Solution
The lampwick plug assembly simplifies the structure by integrating the LED filament with a conductive wire and eliminating the need for a separate resistor, using a plug and plug body configuration that fixes the LED lampwick, and optimizing the glue injection surface to ensure complete sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waterproof glue is injected into the glue injection cavity to achieve waterproofing, then waterproof protection is provided, but the structural complexity increases and the glue injection surface protrudes affecting sealing quality
Solution Approach 1:
The patent merges the resistor with the LED lampwick by packaging the resistor inside the LED filament structure. This integration eliminates the need for a separate resistor installation process and reduces the overall component count, thereby simplifying the structure while maintaining the waterproof function through the optimized plug design
Solution Approach 2:
The patent changes the dimensional relationship of the glue injection surface by making it flush with the end face of the opening rather than protruding. This dimensional adjustment eliminates the protrusion issue, improves sealing quality, and simplifies the overall structure without compromising waterproof protection
2Reliability
If separate resistor and LED lampwick components are used with multiple fixing structures, then functional requirements are met, but the manufacturing process becomes cumbersome and productivity decreases
Solution Approach 1:
The patent combines the resistor and LED lampwick into a single integrated component where the resistor is packaged inside the LED filament. This merging eliminates multiple separate fixing operations and simplifies the assembly process, significantly improving productivity for mass production while ensuring effective electrical connection
Solution Approach 2:
The integrated LED lampwick-resistor component serves multiple functions simultaneously: it provides both the lighting function through the LED filament and the current limiting function through the packaged resistor. This multi-functionality reduces the number of components and assembly steps, enhancing both productivity and manufacturing efficiency
