Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp caps are non-replaceable and have poor waterproof performance due to their integrated structure.
Innovation Solution
A special lamp cap design featuring a detachable lamp bulb male plug connected to a lamp holder female plug with internal threads, a sealing ring, and a nut for secure fixation and sealing, allowing for easy replacement and improved waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an integrated structure is used for the lamp cap, then the manufacturing is simpler, but the lamp cap becomes non-replaceable and waterproof performance deteriorates
Solution Approach 1:
The lamp cap is divided into multiple detachable components: a lamp holder body, a lamp holder base with external threads, and a lamp bulb shell with internal threads. This segmentation allows the lamp cap to be disassembled and reassembled, enabling replacement while maintaining waterproof performance through threaded connections that can be sealed.
2Device complexity
If an integrated structure is used for the lamp cap, then the structure is more compact, but the lamp cap becomes non-replaceable
Solution Approach 1:
The lamp cap is divided into multiple detachable components: a lamp holder body, a lamp holder base with external threads, and a lamp bulb shell with internal threads. This segmentation allows the lamp cap to be disassembled and reassembled, enabling replacement while maintaining waterproof performance through threaded connections that can be sealed.
3Ease of repair
If a detachable structure is implemented, then the replaceability is improved, but the device complexity increases
Solution Approach 1:
The lamp holder base and lamp holder body are integrated into a single component, as are the lamp bulb shell and its components. This merging reduces the number of separate parts while still maintaining detachability between the main assembly and the bulb, simplifying the overall structure while enabling replacement.
4Device complexity
If traditional sealing methods are used in detachable connections, then the assembly is simpler, but the waterproof performance is poor
Solution Approach 1:
A sealing ring is introduced as an intermediary element between the detachable components of the lamp cap. This sealing ring fills the gap between the threaded connections, preventing water infiltration while maintaining the detachable nature of the structure. The sealing ring is a simple additive component that significantly improves waterproof performance.
