Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple individual sensor components are used to detect multiple environmental variables, then measurement capability is improved, but space requirements and device complexity increase
Solution Approach 1:
The patent combines multiple sensor elements (first sensor element for air pressure, second sensor element for humidity) into a single integrated sensor component housed in one housing. This merging approach enables multiple environmental variables to be detected simultaneously while reducing the total space required compared to using separate sensor components for each measurement.
2Area of stationary object
If multiple sensor elements are integrated into a common housing, then space requirements are reduced, but process engineering complexity increases
Solution Approach 1:
The conductor structure serves multiple functions: it provides electrical connections for both the first sensor element (via the connection structure) and the second sensor element (via the electrode structure), and it forms part of the measurement system itself (the electrode structure acts as an interdigital transducer for humidity sensing). This multi-functionality reduces the number of separate components and simplifies the manufacturing process.
3Area of stationary object
If a combined sensor component is designed for multiple variables, then space requirements are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The conductor structure is segmented into functionally distinct parts: the connection structure for electrical connectivity and the electrode structure for sensing. This segmentation allows each part to be optimized and manufactured independently with appropriate precision requirements, while still achieving integrated functionality when assembled in the common housing.
