Waterproof Lamp Without Holder Using Rubber Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional outdoor decorative light strings have high production costs due to the use of numerous metal materials and complex assembly processes, which are not cost-effective and do not meet current production needs.
Innovation Solution
A highly waterproof lamp and light string design that eliminates the need for a metal lamp holder and copper sleeve, utilizing a waterproof rubber base, injection-molded threaded base, and plugging assembly with a threaded cap for electrical connection, reducing material costs and enhancing waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional metal lamp holder and copper sleeve connection mode is used, then electrical connection and mounting are achieved, but manufacturing cost increases significantly
Solution Approach 1:
The patent extracts and eliminates the metal lamp holder and copper sleeve from the traditional connection system. Instead of embedding metal components in the lamp base, the invention uses a plastic lamp base with integrated wire guide holes and a separate waterproof connector that plugs into the lampshade opening, completely removing the need for metal threading and copper sleeve embedding operations.
Solution Approach 2:
The patent replaces expensive metal lamp holders and copper sleeves with inexpensive plastic components. The lamp base uses simple plastic molding with integrated wire guidance, and the electrical connection is achieved through a disposable-style plastic connector with spring contacts, eliminating the need for costly metal fastening components.
2Reliability
If metal lamp holder and copper sleeve are used for connection, then electrical connection is established, but waterproofing performance deteriorates
Solution Approach 1:
The patent merges the waterproofing function with the electrical connection function into a single integrated plastic connector assembly. The connector housing is molded as one piece with internal spring contacts and waterproof sealing features, eliminating the need for separate metal components and simplifying assembly while improving waterproof reliability.
Solution Approach 2:
The patent uses composite plastic materials that combine electrical conductivity, waterproofing, and mechanical connection functions in a single component. The plastic connector incorporates conductive elements and sealing features within its structure, creating a multi-functional component that replaces multiple separate metal and plastic parts.
3Reliability
If plastic is wrapped around copper sleeve, then insulation is provided, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The plastic lamp base structure serves multiple functions simultaneously: it provides mechanical support, guides wires through integrated channels, provides electrical insulation, and creates the mounting structure for the waterproof connector. This multi-functional design eliminates the need for separate copper sleeve wrapping and insulation layers.
