Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If sampling and laboratory analysis is used for radiation detection, then detection can be performed on large or immovable objects, but the detection process becomes time-consuming and may not accurately reflect the actual radiation situation

Engineering Contradiction:

Improvedetection capability for large/immovable objectsVSAvoiddetection time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical sampling and transportation system with a mobile radiation detection apparatus that directly approaches and measures radiation sources in-situ. The detector is mounted on a movable platform with adjustment mechanisms, eliminating the need for physical sample collection and laboratory analysis while providing immediate detection results.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If sampling is used for radiation detection, then detection can be performed on objects that cannot be moved, but the detection results may not truly reflect the actual radiation situation due to sample selection and submission factors

Engineering Contradiction:

Improvedetection capability for difficult-to-move objectsVSAvoidradiation situation accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent replaces the sampling mechanism with direct in-situ measurement capability. The mobile detector can approach and measure radiation sources directly at their location, eliminating sample selection bias and submission delays, thereby providing more accurate and representative radiation data.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a dynamic detection system with movable mounting brackets and adjustable detector positions that can adapt to different radiation sources and geometries. This dynamic capability allows the detector to optimize its position and orientation for accurate measurement of various objects without requiring them to be moved or sampled.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If a fixed radiation detector is used, then the device structure is simple, but the detector cannot be aligned with objects from multiple angles and positions

Engineering Contradiction:

Improvedetector mounting structureVSAvoiddetector alignment capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the fixed detector into a dynamic system with movable mounting brackets that can translate and rotate. The detector can be positioned and oriented in multiple configurations to align with different radiation sources and measurement geometries, providing versatile alignment capability while maintaining relatively simple device structure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent divides the detector mounting system into separable components including movable brackets, adjustment mechanisms, and the detector itself. This segmentation allows independent adjustment of each component to achieve precise alignment while keeping the overall device structure modular and manageable.

Inventive Principle:

Principle #1Segmentation
