Solution Overview

Problem

Existing LED lamps with module group structures lack waterproof functionality, leading to potential damage and increased costs when installed outdoors, necessitating the development of a waterproof lamp module group that can be easily replaced without replacing the entire housing.

Innovation Solution

A lamp module group design incorporating a concentric male and female terminal system with a waterproof rubber ring, sealed by first and second sealing layers, and a heat-conducting housing structure to ensure waterproofing and easy replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a module group structure is used to facilitate maintenance and reduce costs, then the cost of replacing the entire lamp housing is saved, but the lamp module lacks waterproof function and cannot meet outdoor work requirements

Engineering Contradiction:

Improvemaintenance costVSAvoidwaterproof performance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The lamp system is divided into modular components: a waterproof lamp housing and a separate lamp module group. The lamp module group (containing LED lamp board, power supply driving module, and electrical terminals) can be independently replaced without replacing the entire housing, achieving both cost savings and waterproof reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A waterproof connection structure with concentric male and female terminals serves as an intermediary between the lamp module group and the lamp housing. This intermediary component provides both electrical connection and waterproof sealing, allowing the module to be replaced while maintaining the housing's waterproof integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of repair

If the lamp module group is designed for easy replacement without housing, then maintenance becomes simpler and costs are reduced, but the module group lacks integrated waterproof function

Engineering Contradiction:

Improvereplacement convenienceVSAvoidwater damage risk

Core Design Contradiction:

Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The system separates the waterproof function (housing) from the replaceable module (lamp module group), with a specialized waterproof connection structure bridging them. This segmentation allows easy replacement while maintaining waterproof protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A waterproof rubber ring is used as a flexible sealing element in the connection structure between the lamp module group and housing. This flexible film provides reliable waterproof sealing while accommodating the modular replacement design.

Inventive Principle:

Principle #30Flexible shells and thin films

3Adaptability or versatility

If concentric male and female terminals are used for power extraction, then rotational coaxial connection is achieved, but the structure becomes more complex

Engineering Contradiction:

Improverotational connection capabilityVSAvoidterminal structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electrical connection function and mechanical rotational connection function are merged into a single concentric terminal structure. The concentric male and female terminals simultaneously provide electrical contact and enable rotational alignment, reducing the need for separate components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The concentric terminal structure serves multiple functions: electrical power transmission, mechanical connection, and rotational alignment guidance. This multi-functional design reduces overall system complexity despite the specialized geometry of the concentric terminals.

Inventive Principle:

Principle #6Universality (Multi-functionality)
