Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If microwave irradiation is applied to heat the target, then heating speed is improved, but fluid and gas generation attaches to the target and measurement devices reducing efficiency and accuracy
Solution Approach 1:
The patent extracts and removes the harmful fluid and gas generated during microwave heating by introducing a gas collection system with suction nozzles and a collector. This prevents the fluid and gas from attaching to the measurement devices and target, thereby maintaining measurement accuracy and heating efficiency while preserving the high heating speed advantage of microwave irradiation.
Solution Approach 2:
The patent introduces a gas collection system as an intermediary between the microwave heating zone and the measurement devices. This intermediary system captures and removes the harmful fluid and gas before they can interfere with measurements or reduce heating efficiency, thus mediating between the high-speed heating process and the need for accurate measurements.
2Power
If fluid and gas are generated from the heating target, then heating process is intensified, but attachment to inner walls and devices reduces heating efficiency
Solution Approach 1:
The patent converts the harmful effect of fluid and gas generation into a beneficial process by capturing and collecting these byproducts. The gas collection system transforms the harmful attachment and energy loss into a controlled collection process, maintaining heating power while preventing energy loss through attachment to surfaces.
Solution Approach 2:
The patent extracts the harmful fluid and gas from the heating environment using suction nozzles and a collection system. This removal prevents the fluid and gas from attaching to inner walls and measurement devices, thereby maintaining heating efficiency while allowing the heating process to proceed with high power.
3Productivity
If fluid attaches to measurement devices, then temperature measurement is compromised, but continuous monitoring is needed for efficient heating
Solution Approach 1:
The patent introduces a gas collection system as an intermediary protective layer between the microwave heating zone (where fluid is generated) and the measurement devices. This intermediary continuously removes fluid and gas before they can attach to temperature sensors, ensuring continuous accurate monitoring without compromising heating efficiency.
Solution Approach 2:
The patent extracts fluid and gas from the heating environment using suction nozzles positioned near the target and measurement devices. This continuous extraction prevents fluid attachment to temperature sensors, maintaining measurement precision while allowing efficient continuous heating operations.

AI summary
There is provided a heating device that is capable of increasing heating efficiency of a heating target by microwave irradiation. The heating device includes a microwave irradiator configured to irradiate a heating target with microwaves, and a collector configured to collect fluid generated from the heating target that is irradiated with the microwaves. The microwaves are electromagnetic waves with a frequency of 300 MHz to 30 GHz, for example. The heating target includes metal, for example. Furthermore, the heating target includes non-metal such as oil, organic compound, and water, for example. When the heating target is irradiated with the microwaves, the heating target is heated, and non-metal with lower melting point and boiling point than metal becomes fluid and is separated from the heating target.
