Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrical temperature sensors are used, then temperature measurement capability is provided, but the sensors exhibit high flexural stiffness and require electrical connections that cannot be maintained during operation
Solution Approach 1:
The patent replaces electrical temperature sensors with a resonant frequency-based measurement system using an elastomer resonator. The resonator's natural frequency changes with temperature, allowing temperature measurement through electromagnetic field interaction rather than electrical contacts. This substitution eliminates the need for electrical connections and reduces mechanical stiffness issues.
Solution Approach 2:
The patent introduces an elastomer resonator as an intermediary element embedded in the elastomer product. This resonator couples the temperature field to the electromagnetic field, allowing indirect temperature measurement through frequency shifts. The resonator acts as a mediator that translates temperature changes into measurable electromagnetic signal changes without requiring direct electrical contact with the product.
2Ease of operation
If infrared temperature measurement devices are used, then contactless temperature measurement is achieved, but dust and abrasion on the rubber product distort the measurement
Solution Approach 1:
The patent embeds the elastomer resonator directly inside the elastomer product, nesting the measurement element within the measured object. This internal placement allows the resonator to measure the core temperature from within, unaffected by external factors like dust and abrasion on the surface. The resonator is surrounded by the elastomer material, ensuring it measures the internal temperature rather than being influenced by surface conditions.
3Measurement precision
If an elastomer resonator embedded in the elastomer material is used, then contactless and disturbance-resistant core temperature measurement is achieved
Solution Approach 1:
The elastomer resonator serves multiple functions: it acts as both a structural component of the elastomer product and a temperature sensing element. The resonator's dual role as both part of the product structure and the measurement mechanism reduces the need for separate sensing components, thereby managing system complexity while achieving accurate temperature measurement.
