Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If contactless temperature measurement methods are used, then material compatibility issues are eliminated, but measurement precision is insufficient
Solution Approach 1:
The system segments the heating function into multiple independently controllable electromagnetic radiation sources arranged in a grid pattern, allowing selective activation of specific zones for both heating and temperature measurement, thereby improving measurement precision while maintaining contactless operation
Solution Approach 2:
The system changes the parameters of electromagnetic radiation (wavelength, intensity, duration) to optimize both the heating effect and the temperature measurement signal, enabling high-precision contactless measurement by adjusting radiation parameters to exceed detection thresholds
2Use of energy by moving object
If contact-based heating methods are used, then heat delivery is efficient, but material compatibility problems and overheating risks arise
Solution Approach 1:
The system replaces mechanical contact-based heating with electromagnetic radiation-based heating, eliminating material compatibility issues and overheating risks while maintaining efficient heat delivery through direct electromagnetic energy transfer to the target material
Solution Approach 2:
The system applies local quality by enabling selective heating of specific zones through independently controllable radiation sources, allowing precise spatial control of heat delivery to different regions of the sample without uniform overheating
3Measurement precision
If temperature sensors are placed close to the measured object, then infrared radiation collection is maximized, but the measurement system becomes complex and requires isolation
Solution Approach 1:
The system combines heating and temperature measurement functions into a single integrated platform using electromagnetic radiation, eliminating the need for separate heating elements and temperature sensors, thereby reducing system complexity and isolation requirements while maintaining high measurement precision
4Stability of the object's composition
If existing temperature control systems are used, then constant temperature maintenance is achieved, but selective modification of temperature field profiles is not possible
Solution Approach 1:
The system segments the radiation field into multiple independently controllable zones, allowing selective modification of temperature profiles in different regions while maintaining constant temperature in other areas, thereby achieving both stability and adaptability simultaneously
Solution Approach 2:
The system implements dynamic control of radiation source intensity and timing, enabling real-time modification of temperature field profiles while maintaining overall temperature stability through feedback-controlled adjustments

Implementation Method 1
a source of electromagnetic waves, in a container the wall of which is transparent to electromagnetic waves of a given wavelength
Implementation Method 2
In contactless methods, the subject of the measurement is the wavelength of the emitted infrared radiation
Implementation Method 3
The measurement proceeds based on Planck's law and Wien's law. Planck's law describes the amount of energy radiated by an idealised black body
Implementation Method 4
Wien's law on the other hand concerns a change in wavelength with respect to a change in temperature
Implementation Method 5
a specialised controller with a microprocessor connected by wires to a thermal radiation detector... in a feedback system which provides regulation and stabilisation of the power of sources, and consequently the temperature in the irradiated object
