Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional invasive measurement methods are used to determine fluid level and alcohol content, then measurement can be performed, but contamination is introduced and labor requirements increase
Solution Approach 1:
The patent replaces mechanical/invasive measurement systems with electromagnetic sensing. External sensors mounted on the container wall use electromagnetic fields to detect fluid level and properties through the container wall, eliminating the need to physically insert measurement tools into the liquid and thus preventing contamination.
Solution Approach 2:
The container wall itself serves as an intermediary medium. The electromagnetic sensors detect signals that pass through or interact with the container wall to obtain information about the liquid inside without direct contact, using the wall as a mediator between the external sensor and internal liquid.
2Measurement precision
If conventional invasive measurement methods are used, then measurement can be performed, but labor intensity increases
Solution Approach 1:
The system enables automatic continuous monitoring without human intervention. The external sensors continuously measure fluid level and properties, and the processing system automatically analyzes the data and generates alerts, eliminating the need for manual sampling and measurement operations.
Solution Approach 2:
Electromagnetic sensing replaces manual mechanical measurement operations, allowing automated data collection and elimination of repetitive labor-intensive sampling tasks.
3Measurement precision
If modern analytical methods are used, then measurement accuracy improves, but equipment complexity and cost increase
Solution Approach 1:
The patent uses electromagnetic sensing technology that provides analytical-level measurement accuracy through non-invasive external sensors, replacing the need for complex laboratory equipment while maintaining high measurement precision through signal processing and analysis.
