Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If common detectors are used in humid and warm environments, then the detector can operate in various conditions, but the internal components are highly sensitive to the working environment causing performance anomalies and index decreases

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidperformance stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies the inert atmosphere principle by creating a sealed internal environment within the detector housing that isolates sensitive components from the external humid and warm environment. The sealing structure maintains a protected internal atmosphere, preventing moisture and contaminants from contacting internal components, thereby ensuring reliable operation in various environmental conditions without performance degradation

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

2Ease of manufacture

If the detector housing is not fully sealed, then the structure is simpler and easier to manufacture, but the detector is prone to damage in unexpected situations such as immersion in water or exposure to rain

Engineering Contradiction:

Improveassembly easeVSAvoiddamage resistance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent implements a fully sealed housing structure that creates a protected internal environment, preventing water, rain, and contaminants from contacting internal components. This sealing approach ensures the detector can withstand immersion and exposure to rain without damage, while the modular design with sealing frames and connecting columns maintains manufacturing feasibility

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

3Object-affected harmful factors

If a fully sealed structure is implemented, then moisture resistance and dust prevention are achieved, but the device complexity increases

Engineering Contradiction:

Improvemoisture and dust resistanceVSAvoidstructural complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the sealing structure into modular components including a sealing frame with connecting columns, a base, and a cover. This segmented design allows each component to be manufactured and assembled separately, reducing overall complexity while achieving full sealing. The modular structure makes maintenance and replacement easier compared to a monolithic sealed housing

Inventive Principle:

Principle #1Segmentation
