Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement sensors are installed in multiple distributed process vessels, then measurement coverage is improved, but user tracking and information collection becomes more difficult
Solution Approach 1:
The system divides the monitoring function into distributed segments by placing individual display devices at each process vessel location. Each display device is independently connected to its local sensor, creating modular monitoring units that can be tracked and managed separately, thus improving ease of operation while maintaining comprehensive measurement coverage.
Solution Approach 2:
Display devices serve as intermediary elements between the sensors and users. These intermediaries collect measurement data from local sensors and present it in an easily observable format at each vessel location, bridging the gap between distributed measurement points and user monitoring needs.
2Reliability
If display device is wired to sensor, then connection reliability is improved, but installation flexibility and ease of monitoring is reduced
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The display device receives measurement data wirelessly from the sensor, eliminating physical cables while maintaining reliable data transmission. This substitution provides both connection reliability through stable wireless protocols and installation flexibility by removing cable routing constraints.
3Ease of operation
If display device is mounted inside container, then monitoring accessibility is improved, but device protection from environmental factors is worsened
Solution Approach 1:
The display device is nested within a protective housing or enclosure that shields it from environmental factors such as moisture, dust, and temperature extremes. This nested structure allows the device to be mounted inside or near the container while maintaining protection, combining monitoring accessibility with environmental resistance.
4Measurement precision
If multiple display devices are deployed, then monitoring coverage is improved, but system complexity increases
Solution Approach 1:
The display devices are designed as universal, standardized units that can be deployed at multiple locations with identical functionality. Each device performs the same set of functions (displaying measurement data, providing visual indicators, and communicating with its local sensor), which simplifies the overall system architecture despite the increased number of devices. The uniformity across multiple devices reduces complexity compared to having customized monitoring solutions at each location.
