Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measurement apparatus uses electrodes to measure dielectric constant for determining physical properties, then measurement capability is provided, but measurement precision deteriorates due to ambient condition interference
Solution Approach 1:
A metal plate is introduced as an intermediary component between the measurement electrodes and the ambient environment. This metal plate acts as a shield that blocks external electromagnetic interference and environmental factors from affecting the dielectric constant measurement, thereby protecting the measurement precision without interfering with the measurement capability
2Measurement precision
If ambient condition interference is present during dielectric constant measurement, then measurement capability is maintained, but measurement precision deteriorates
Solution Approach 1:
The metal plate serves as a protective intermediary that creates a controlled measurement environment. It reliably blocks ambient electromagnetic waves and environmental interference, ensuring that the dielectric constant measurement remains reliable and precise regardless of external conditions
