Waterproof Lamp Modular Base and Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof lighting devices often rely on plastic injection molding for sealing, which while effective, may not provide a robust or cost-efficient solution for ensuring complete waterproofing, particularly in designs requiring multiple connections and cable management.
Innovation Solution
A waterproof lamp design featuring a lamp base with multiple chambers and mounting openings, where the mounting member is positioned higher than the openings, allowing liquids to flow out while preventing entry into internal components, and a cable assembly with conductive members and protection plate to manage cables without injection molding, ensuring effective sealing and preventing short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic injection molding is used to seal the lamp holder and cables, then waterproofing is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The lamp structure is divided into separate modular components: lamp base, lamp holder, cable assembly, and protection plate. Each component can be manufactured independently using simpler processes, then assembled together. This eliminates the need for complex plastic injection molding while maintaining waterproofing through the modular design and sealing interfaces between components.
Solution Approach 2:
A protection plate is introduced as an intermediary component between the cable assembly and the lamp holder. This protection plate provides sealing and electrical insulation without requiring plastic injection molding, acting as a mediator that ensures waterproofing while simplifying the manufacturing process.
2Reliability
If plastic injection molding is used to seal the lamp holder and cables, then waterproofing is achieved, but manufacturing cost increases
Solution Approach 1:
By segmenting the lamp into separate components (lamp base, lamp holder, cable assembly, protection plate), each part can be manufactured using simpler, less expensive processes. The modular approach eliminates the need for expensive plastic injection molding while maintaining waterproofing through proper sealing at the interfaces between components.
Solution Approach 2:
The design uses simpler, more cost-effective materials and components that can be easily replaced if needed. The protection plate and cable assembly can be manufactured from cheaper materials compared to fully molded plastic components, reducing overall manufacturing cost while maintaining adequate waterproofing.
3Adaptability or versatility
If multiple connections and cable management are implemented, then functionality is improved, but waterproofing becomes more difficult to ensure
Solution Approach 1:
The cable assembly is segmented into separate conductive members and insulation components, allowing multiple electrical connections to be made through dedicated pathways. The protection plate provides a structured interface for managing these connections while maintaining sealing, enabling multiple connections without compromising waterproofing.
Solution Approach 2:
The protection plate serves as an intermediary structure that manages multiple cable connections and electrical contacts while maintaining the waterproof seal. It provides a dedicated interface for cable entry and connection, allowing functional complexity to increase without compromising the waterproofing integrity of the lamp.

AI summary
A waterproof lamp includes a lamp base defining a first chamber and comprising a mounting member received in the first chamber, and a cap threadedly connected to the lamp base. The lamp base defines a first mounting opening and a second mounting opening that both communicate with the first chamber. The mounting member defines a second chamber and includes a first mounting post received in the second chamber. The first mounting post defines at least two mounting holes. The mounting member defines a third mounting opening and a fourth mounting opening that communicate with the second chamber and communicate with the at least two mounting holes through the second chamber, and includes a protection plate covering the third mounting opening and the fourth mounting opening.
