Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple radiation sensors are integrated over a large surface area, then the coverage area and detection capability are improved, but the device complexity increases

Engineering Contradiction:
Improvedetection surface areaVSAvoidsensor array complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The detection surface is divided into multiple discrete sensor elements arranged in a grid pattern, where each sensor independently detects radiation at its location. This segmentation allows the large surface area to be covered by multiple simple, identical units rather than one complex sensor, reducing overall device complexity while maintaining extensive coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple identical radiation sensors are replicated across the detection surface in a regular array pattern. Each sensor is a copy of the basic detection unit, allowing the system to achieve large-area coverage through repetition of simple components rather than designing a single complex sensor system.

Inventive Principle:
Principle #26Copying

2Reliability

If real-time radiation detection and reporting is implemented, then worker safety is improved, but the need for active alert circuitry and power consumption increases

Engineering Contradiction:
Improveworker safetyVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system continuously monitors radiation levels in real-time and provides immediate feedback to workers through visual indicators. This continuous feedback mechanism enables workers to understand their exposure status moment-to-moment and take corrective actions, significantly improving safety reliability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Visual indicators change color based on detected radiation levels, providing intuitive real-time feedback to workers. The color-changing mechanism offers a simple, energy-efficient way to communicate radiation status without requiring complex displays or high power consumption, while maintaining reliable safety information delivery.

Inventive Principle:
Principle #32Color changes

3Device complexity

If passive dosimeters are used, then the device complexity is reduced, but the measurement is retrospective rather than real-time

Engineering Contradiction:
Improvesensor system complexityVSAvoidmeasurement timing delay
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system replaces passive mechanical dosimeters with active electronic sensors that continuously monitor radiation levels and provide real-time digital output. This substitution enables immediate measurement feedback while keeping each individual sensor unit relatively simple, eliminating the time delay inherent in retrospective dosimetry.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
