Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed gas detection device is used, then the device structure is simple, but the degree of freedom is low and the detection range is small
Solution Approach 1:
The patent applies dynamics by transforming the fixed detection device into a movable one. The detection device is mounted on a mobile platform (such as a robot or vehicle) that can move freely in three-dimensional space, allowing the detection range to expand from a fixed point to a dynamic coverage area. This resolves the contradiction by making the device adaptable to different locations while the mobility system handles the complexity of movement control.
Solution Approach 2:
The patent introduces another dimension by adding spatial mobility to the detection device. Instead of being confined to a fixed position, the device can move in multiple directions (x, y, z axes) and orient itself in different angles. This dimensional expansion dramatically increases the detection range without requiring an overly complex fixed structure, as the mobility system provides the necessary adaptability.
2Ease of operation
If a fixed gas detection device is used, then the device is simple to operate, but it is inconvenient to adjust and has low degrees of freedom
Solution Approach 1:
The patent replaces manual mechanical adjustment with automated control systems. The mobile platform and detection device are equipped with sensors, motors, and control algorithms that automatically adjust the device's position and orientation based on detection needs. This substitution maintains ease of operation (through automated control) while dramatically increasing degrees of freedom (through motorized movement and positioning).
3Reliability
If the detection device lacks adjustment capability, then the device structure is simple, but it creates safety hazards
Solution Approach 1:
The patent implements self-service by equipping the detection device with autonomous navigation and positioning capabilities. The device can automatically move to optimal detection locations, adjust its orientation toward gas sources, and return to base stations for recharging or data transmission. This self-service capability enhances work safety by reducing the need for manual intervention in hazardous environments while the integrated automation system manages the complexity of adjustment mechanisms.
