Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If chemical reaction detection method is used, then detection mechanism is simple, but detection range is limited to fixed small space and response speed is slow
Solution Approach 1:
The patent replaces the chemical reaction-based detection mechanism with an electromagnetic wave-based detection system. The application terminal transmits electromagnetic waves through the space, and the equipment terminal receives these waves to detect gas composition changes based on signal attenuation characteristics, eliminating the need for physical chemical sensors and enabling unlimited detection range.
Solution Approach 2:
The electromagnetic wave detection system can detect various types of gases by analyzing different attenuation characteristics of the waves passing through the space. The same detection apparatus can monitor multiple gas compositions simultaneously, providing universal detection capability across different gas types and space environments.
2Area of stationary object
If electromagnetic wave detection is used, then detection range becomes unlimited and response speed improves, but device complexity increases
Solution Approach 1:
The detection system is divided into two independent terminals: an application terminal that transmits electromagnetic waves and an equipment terminal that receives and analyzes the waves. This segmentation allows each terminal to have specialized, relatively simple functions while achieving complex detection capabilities through their coordinated operation across unlimited space.
Solution Approach 2:
Electromagnetic waves serve as an intermediary carrier between the application terminal and equipment terminal. The waves traverse the detection space and carry information about gas composition changes, enabling the system to detect distant gas states without requiring direct physical contact or complex intermediate sensing mechanisms.
3Productivity
If chemical reaction detection is used, then device structure is simple, but real-time monitoring capability is lost
Solution Approach 1:
The electromagnetic wave transmission and reception operates continuously, with the application terminal constantly emitting detection waves and the equipment terminal continuously receiving and analyzing them. This continuous operation enables real-time monitoring of gas composition changes throughout the detection space, providing uninterrupted safety surveillance.
Solution Approach 2:
The equipment terminal calculates attenuation values by comparing transmitted and received electromagnetic wave characteristics, then uses this feedback information to determine gas composition changes in real-time. The system continuously adjusts its detection based on the received signal characteristics, enabling dynamic real-time monitoring capability.
