Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a person enters a hazardous region to check chemical hazard situations, then contamination detection can be performed, but life safety is compromised due to potential exposure to contaminants
Solution Approach 1:
The patent introduces an unmanned moving device as an intermediary between the operator and the hazardous contaminated region. This device carries detection sheets and imaging equipment to perform contamination detection remotely, eliminating the need for human entry into dangerous areas while maintaining reliable detection capabilities through automated sampling and imaging processes
Solution Approach 2:
The patent uses detection sheets that capture chemical contamination patterns and imaging units that create visual copies of the contamination state. These copies are then transmitted to safe locations for analysis, allowing remote assessment of hazardous conditions without direct human exposure while maintaining accurate contamination detection
2Productivity
If a person moves in a hazardous region to perform contamination detection, then detection operation can be conducted, but maneuverability is deteriorated due to safety concerns and restricted movement
Solution Approach 1:
The patent replaces the mechanical system of human movement with an unmanned moving device that can navigate hazardous regions autonomously or remotely controlled. This substitution eliminates the maneuverability constraints and safety concerns associated with human movement while maintaining or improving detection operation efficiency through automated navigation and sampling capabilities
Solution Approach 2:
The patent employs a moving device with dynamic movement capabilities that can adapt its path and speed based on environmental conditions and detection requirements. The device includes movable components such as wheels or rotors that allow flexible navigation through difficult terrains without the physical limitations imposed on human operators
3Measurement precision
If detection sheets are exposed to the outside for chemical substance detection, then contamination detection accuracy is improved, but the device complexity increases due to additional mechanical components
Solution Approach 1:
The patent extracts the detection function into separate, modular detection sheets that can be independently exposed to the environment. These sheets are housed in simple protective casings with minimal mechanical components, allowing accurate chemical detection while reducing overall device complexity through functional separation and modular design
