Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If conventional electric bulbs or fluorescent lamps are used, then lighting function is provided, but lifespan is short and frequent replacement is required

Engineering Contradiction:

ImprovelifespanVSAvoidtime for frequent replacement

Core Design Contradiction:

Duration of action of moving objectVSLoss of time

Solution Approach 1:

The patent replaces conventional short-lived bulbs with LED modules that have dramatically extended lifespans. The LED module is designed as a replaceable unit that can operate for tens of thousands of hours, eliminating the need for frequent replacements while maintaining the disposable/replaceable nature of the lighting element.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Illumination intensity

If conventional fluorescent lamps are used, then lighting function is provided, but illuminance is gradually decreased over time

Engineering Contradiction:

ImproveilluminanceVSAvoidservice time

Core Design Contradiction:

Illumination intensityVSDuration of action of moving object

Solution Approach 1:

The patent employs LED technology which maintains stable luminous output over its operational lifetime. Unlike fluorescent lamps that degrade in illuminance over time, the LED module provides consistent lighting performance throughout its extended service life, with the entire module replaced as a unit when end-of-life is reached.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Use of energy by moving object

If LED module is used for outdoor lighting, then long lifespan and energy efficiency are achieved, but heat dissipation becomes critical

Engineering Contradiction:

Improveenergy efficiencyVSAvoidheat dissipation

Core Design Contradiction:

Use of energy by moving objectVSTemperature

Solution Approach 1:

The patent converts the harmful heat generated by the LED module into a manageable thermal flow by designing a heat sink structure with optimized fin geometry. The heat dissipation challenge is transformed into a beneficial feature where the structured heat sink efficiently transfers and disperses heat to the surrounding air, preventing overheating while maintaining the energy efficiency advantages of LED technology.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

4Reliability

If LED module is used for outdoor lighting, then durability is improved, but waterproofing and coupling configuration require optimization

Engineering Contradiction:

ImprovedurabilityVSAvoidwaterproofing and coupling configuration

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the waterproofing and coupling functions into a unified connector assembly. The coupling structure incorporates sealing elements and waterproof barriers that protect the electrical connections and internal components from moisture and environmental damage, combining multiple protective functions into a single integrated component rather than separate systems.

Inventive Principle:

Principle #5Merging (Combining)
