Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional bulb structure is used, then manufacturing is simple, but waterproof property is poor

Engineering Contradiction:

Improvewaterproof propertyVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bulb is divided into distinct functional modules: a waterproof bulb shell, a separate PCB circuit board assembly, a lamp holder, and a sealing structure. This segmentation allows each component to be optimized independently for waterproofing while maintaining overall structural integrity and simplicity in assembly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A sealing base acts as an intermediary component between the PCB circuit board and the bulb shell, providing the critical waterproof barrier. This intermediary element isolates the electronic components from moisture while maintaining electrical connectivity, resolving the contradiction between waterproofing and structural simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Illumination intensity

If PCB is vertically mounted, then assembly is traditional, but illumination angle is limited

Engineering Contradiction:

Improveillumination angleVSAvoidassembly convenience

Core Design Contradiction:

Illumination intensityVSEase of manufacture

Solution Approach 1:

The PCB circuit board is mounted horizontally rather than vertically, inverting the traditional orientation. This inversion allows the LED lamp beads to face upward and emit light in multiple directions including 180 degrees, significantly expanding the illumination angle while the horizontal mounting simplifies the assembly process within the bulb shell.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If sealing base is added, then waterproof property improves, but device complexity increases

Engineering Contradiction:

Improvewaterproof propertyVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sealing base performs multiple functions simultaneously: it seals the connection between the PCB and bulb shell, provides waterproof protection, supports the PCB assembly, and facilitates electrical connectivity. This multi-functionality reduces the need for separate components, maintaining simplicity while achieving excellent waterproofing.

Inventive Principle:

Principle #6Universality (Multi-functionality)
