Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sensor plates are built into the pressure scanner assembly, then structural stability is improved, but ease of repair deteriorates as users cannot easily replace sensor plates
Solution Approach 1:
The pressure scanner assembly is divided into modular components, with sensor plates being separable from the main assembly. This segmentation allows the sensor plate to be replaced independently while maintaining the stability of the overall system structure.
Solution Approach 2:
The sensor plate configuration transitions from fixed to dynamically replaceable. The system is designed to accommodate sensor plate removal and installation, enabling easy repair while maintaining structural integrity during operation.
2Ease of repair
If sensor plates are made removable for easy replacement, then ease of repair is improved, but device complexity increases due to electronic configuration disruptions
Solution Approach 1:
The sensor plate includes self-identifying features such as unique identifiers or electronic tags that automatically communicate with the pressure scanner assembly. This self-service mechanism allows the system to automatically configure electronic settings when a sensor plate is installed, eliminating manual configuration complexity.
Solution Approach 2:
The electronic configuration system is designed to universally accommodate different sensor plate types. A single configuration mechanism handles multiple sensor plate variants, reducing overall system complexity while maintaining ease of replacement.
3Measurement precision
If replacement sensor plates are required to have the same pressure range and correction coefficients, then measurement precision is maintained, but adaptability deteriorates
Solution Approach 1:
The system allows correction coefficients and pressure range parameters to be dynamically changed based on the installed sensor plate's characteristics. Each sensor plate can have its own parameter set stored in memory, enabling precise measurements across different pressure ranges without requiring manual recalibration.
Solution Approach 2:
Each sensor plate is designed with localized correction coefficients specific to its pressure range and characteristics. This local quality approach allows each sensor plate to maintain optimal measurement precision for its specific function while being interchangeable with other sensor plates of different specifications.
4Measurement precision
If manual entry of correlation and correction coefficients is required, then measurement precision can be maintained, but productivity deteriorates due to time-consuming calibration
Solution Approach 1:
The sensor plate incorporates memory storage that automatically provides correlation and correction coefficients to the pressure scanner assembly. This self-service approach eliminates the need for manual entry of calibration data, maintaining measurement precision while dramatically improving productivity by removing the time-consuming calibration step.

AI summary
A pressure scanner assembly having at least one replaceable sensor plate, wherein each of the replaceable sensor plates has at least one pressure sensor adapted to transmit a signal substantially indicative of a sensed pressure condition. A memory chip, which stores correction coefficients for each of the pressure sensor to compensate for thermal errors, may be installed on each of the replaceable sensor plates. The signals from the pressure sensors are multiplexed and may be outputted in analog or digital form. The pressure scanner assemblies described herein have sensor plates that can be interchanged with other sensor plates of the same or different pressure range without disrupting the electronic configuration of the pressure scanner assembly or having to recalibrate and/or update the memory chip installed thereon.
