Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional air quality monitoring systems are used, then air quality information can be obtained, but the information is limited to large area monitoring and cannot provide localized air quality data
Solution Approach 1:
The gas detecting module is divided into functionally independent regions: a micro-pump-loading region for gas intake, a detection region for gas analysis, and a gas-flowing-path region for gas transport. This segmentation allows each region to be optimized for its specific function while maintaining overall system compactness, enabling localized detection capability without excessive complexity.
Solution Approach 2:
The gas sensor is positioned within the detection region and electrically connected to the driving circuit board, creating a nested arrangement where the sensing element is integrated into the circuit assembly. This nesting reduces spatial requirements and simplifies the overall structure while maintaining detection precision.
2Ease of operation
If a portable gas detecting module is integrated with mobile devices, then easy access to localized air quality information is achieved, but the device size and integration complexity increase
Solution Approach 1:
The driving circuit board serves multiple functions: it provides electrical connections for the gas sensor, powers the micro pump, and interfaces with external devices. This multi-functionality reduces the number of separate components needed, making the module more suitable for integration into portable devices while maintaining ease of operation.
Solution Approach 2:
The module utilizes vertical stacking of functional regions (micro-pump-loading region, detection region, gas-flowing-path region) rather than only horizontal expansion. This three-dimensional arrangement reduces the module's footprint, enabling portable integration without proportionally increasing device complexity.
3Productivity
If a micro pump is used to accelerate gas flow, then detection efficiency is improved, but the device size and manufacturing complexity increase
Solution Approach 1:
The micro pump is integrated with the driving circuit board, suggesting the use of electrostatic or electromagnetic actuation rather than traditional mechanical pumping mechanisms. This substitution reduces moving parts and simplifies manufacturing while maintaining the ability to accelerate gas flow for efficient detection.
Solution Approach 2:
The micro pump structure is merged with the driving circuit board assembly, where the pump's driving mechanism is integrated into the circuit board's layered structure. This merging eliminates separate pump housings and connections, reducing overall device complexity while maintaining detection productivity.
4Volume of moving object
If the gas detecting module is designed with a compact modular structure, then integration with portable devices is facilitated, but the internal space for components is reduced
Solution Approach 1:
The module employs vertical stacking of functional regions (micro-pump-loading region, detection region, gas-flowing-path region) to achieve compactness in the horizontal plane. This three-dimensional arrangement accommodates all necessary components within a small footprint while managing internal space efficiently.
Solution Approach 2:
Components are arranged in nested configurations where the gas sensor is positioned within the detection region and the micro pump is integrated into the micro-pump-loading region. This nesting maximizes the use of available space while maintaining clear functional separation, facilitating portable device integration without excessive complexity.
