Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple gas detection modules with different detection techniques are prepared in advance, then various gas detection techniques can be accommodated, but all modules become large in size due to size standardization
Solution Approach 1:
The gas detection module is divided into separate components: a chamber that remains in the detector and gas sensors that can be independently replaced. This segmentation allows the chamber to be optimized for compact size while sensors can be standardized to fit different detection techniques, resolving the contradiction between versatility and size.
Solution Approach 2:
The chamber is designed with a universal interface that can accommodate multiple types of gas sensors through standardized mounting and electrical connections. This universality allows a single compact chamber design to support various detection techniques (semiconductor, catalytic, infrared) without requiring size standardization across all modules.
2Volume of stationary object
If a compact gas detector design is implemented, then the overall size is reduced, but accommodating various gas detection techniques becomes difficult
Solution Approach 1:
The patent separates the accommodation of different detection techniques into a different dimensional space - the sensor type dimension - while keeping the chamber geometry compact. The chamber provides a standardized interface that accommodates various sensor types through its design, allowing technical versatility without increasing physical size.
3Ease of repair
If gas sensors are made replaceable, then maintenance and component replacement become easier, but the connection structure becomes more complex
Solution Approach 1:
The detachable connection structure is segmented into standardized interfaces: a sensor-side connector and a corresponding receptacle on the chamber. This segmentation enables easy sensor replacement while keeping each interface simple and well-defined, resolving the contradiction between ease of repair and structural complexity.
Solution Approach 2:
The connection structure uses standardized electrical and mechanical parameters (connector types, contact arrangements, sealing interfaces) that simplify the replacement process. By establishing fixed parameters for the connection interfaces, the system achieves ease of repair without excessive complexity.
