Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radiation detector is fixed in a specific position on the working machine, then the structure is simple and easy to manufacture, but the size of the object of detection is limited and the distance to the object of detection cannot be adjusted
Solution Approach 1:
The radiation detector is mounted on a support structure that enables movement relative to the working machine, allowing dynamic adjustment of the detection distance and position. This resolves the contradiction by transforming a fixed structure into a movable one, thereby increasing versatility without requiring multiple separate devices.
Solution Approach 2:
The radiation detecting attachment is designed to be universally applicable to various object sizes and detection distances. By incorporating movable support and adjustable positioning mechanisms, a single device can serve multiple detection scenarios, achieving versatility without proportionally increasing overall system complexity.
2Measurement precision
If the radiation detector is positioned close to the object of detection to improve measurement accuracy, then the measurement precision is improved, but the risk of detector failure or breakage increases due to external forces
Solution Approach 1:
An elastic member is introduced between the radiation detector and the support structure to provide cushioning and shock absorption. This beforehand cushioning protects the detector from external forces and impacts, allowing it to operate closer to the object of detection for improved measurement precision without compromising reliability.
Solution Approach 2:
The elastic member acts as an intermediary element between the radiation detector and the rigid support structure. It mediates the transmission of external forces, reducing direct mechanical stress on the detector while maintaining the close positioning necessary for accurate radiation measurement.
3Adaptability or versatility
If the radiation detector operates in a confined space with limited air flow, then the detection can proceed in restricted areas, but the air dose interferes with accurate radiation measurement
Solution Approach 1:
Air discharge nozzles are provided to actively remove and discharge the air in the detection area, extracting the source of interference (radioactive air dose) from the measurement environment. This allows accurate radiation measurement to be achieved even in confined spaces where natural air flow is limited.
Solution Approach 2:
A pneumatic system with air discharge nozzles is used to control and replace the air in the detection area. By introducing fresh air and discharging contaminated air, the system maintains measurement accuracy in confined spaces through active air management rather than relying on passive diffusion.

Function Achieved in This Case
Enables efficient and versatile radiation detection, reducing detector failure and accurately measuring radiation levels, facilitating efficient sorting and demolition procedures without additional machinery, even in confined spaces.
Implementation Method 1
a radiation detector for detecting radiation
Implementation Method 2
at least one of the radiation detectors may be supported via an elastic member. In this case, the possibility of causing failure, breakage, or the like, of the radiation detector can be reduced even if a large external force is applied to the radiation detector
Implementation Method 3
one or more discharge nozzles disposed to be capable of replacing pre-replacement air between the radiation detector and a detection area of the object of detection may be included, and post-replacement air having a reduced amount of a radioactive substance contained in the pre-replacement air may be discharged from the one or more discharge nozzles
