Solution Overview
Problem
Existing methods for sensing load parameters in closed chambers, such as cooking devices, are complex, expensive, and unsuitable for real-time monitoring, especially at high temperatures or in poor visibility conditions, as they require manual input and are limited by the need for fixed electric field distributions.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical sensing systems are used to detect load parameters in closed chambers, then object sensing and measurement can be performed, but the systems become complex and expensive
Solution Approach 1:
The patent replaces complex optical sensing systems with electromagnetic radiation-based detection. Instead of using sophisticated optical sensors and image processing systems, the invention uses electromagnetic waves (such as microwave fields) to probe the closed chamber and detect load parameters through changes in the electromagnetic field characteristics, thereby simplifying the overall system while maintaining measurement capability
Solution Approach 2:
The patent changes the detection parameter from optical properties to electromagnetic field parameters. By measuring changes in electromagnetic field distribution, impedance, or resonance characteristics when objects are present in the closed chamber, the system achieves load parameter detection through a different physical domain, reducing system complexity and cost
2Measurement precision
If fixed electric field distributions are used for measurements, then measurement procedures can be standardized, but real-time monitoring becomes impossible
Solution Approach 1:
The patent introduces dynamic variation of the electric field distribution through time. Instead of using a fixed electric field configuration, the system varies the electromagnetic field parameters (such as frequency, phase, or spatial distribution) over time, enabling multiple measurements to be taken under different field conditions. This dynamic approach allows for real-time monitoring while maintaining measurement accuracy through pattern recognition across multiple states
3Measurement precision
If manual input is required for load parameters, then data accuracy can be ensured, but automation is reduced
Solution Approach 1:
The patent enables the system to automatically detect and determine load parameters without manual input. The electromagnetic radiation-based sensing system autonomously probes the closed chamber, measures field characteristics, and processes the data to identify load parameters such as object presence, position, or properties, thereby achieving full automation while maintaining measurement accuracy through sophisticated signal processing and pattern recognition
4Measurement precision
If optical systems are used in harsh conditions, then detection can be performed, but reliability decreases due to steam and poor visibility
Solution Approach 1:
The patent replaces optical sensing systems that are sensitive to visibility conditions with electromagnetic radiation-based detection. Electromagnetic waves in certain frequency ranges (such as microwave frequencies) can penetrate steam and poor visibility conditions that block optical signals, thereby maintaining detection capability and reliability in harsh environments where optical systems fail

AI summary
A method of sensing at least one load parameter of a closed chamber by a sensing device by means of electromagnetic radiation is described, in which measurements of at least one measured variable are used. A first measurement is carried out when there is a first spatial distribution of the electric field generated by the electromagnetic radiation. At least a second measurement is carried out when there is a second spatial distribution of the electric field generated by the electromagnetic radiation, which differs from the first spatial distribution of the electric field.
