Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic wave generation devices using multiple resonant tunneling diodes for terahertz wave generation face high instantaneous power consumption and potential interference due to simultaneous oscillation of elements, which is inefficient and increases electric power consumption.
Innovation Solution
The device divides electromagnetic wave generation elements into groups, oscillating them in timed sequences to reduce instantaneous power consumption and minimize interference by using different oscillation frequencies or phases within each group.

Engineering Contradiction Analysis
1Reliability
If a large number of lamps are arranged in the irradiation pool to increase sterilization coverage, then the sterilization effectiveness is improved, but the device complexity and cost increase
Solution Approach 1:
The irradiation pool is divided into multiple irradiation regions, with each region equipped with its own independently controllable lamp. This segmentation allows targeted sterilization of specific areas rather than requiring all lamps to operate simultaneously, reducing overall device complexity while maintaining sterilization effectiveness.
Solution Approach 2:
The system implements dynamic control where lamps are selectively activated based on the position of the treatment device and the specific irradiation needs. The control unit dynamically adjusts which lamps are operating, allowing the system to adapt to different surgical scenarios and reduce unnecessary energy consumption and complexity.
2Reliability
If multiple lamps are operated simultaneously to provide comprehensive irradiation, then the sterilization coverage is improved, but the energy consumption increases
Solution Approach 1:
Instead of operating all lamps simultaneously, the system activates only the necessary subset of lamps based on the treatment requirements and device position. This partial action approach provides sufficient sterilization coverage for each specific surgical step without the excessive energy consumption of running all lamps at once.
Solution Approach 2:
The irradiation process is conducted in periodic cycles corresponding to different surgical steps. Lamps are activated and deactivated in sequence as the treatment device moves between different irradiation regions, providing continuous sterilization coverage while minimizing total energy consumption through periodic rather than continuous operation of all lamps.

AI summary
In an electromagnetic wave generation device including a plurality of electromagnetic wave generation elements, an instantaneous maximum power consumption during an electromagnetic wave generation operation is reduced. Specifically, the electromagnetic wave generation device includes a plurality of electromagnetic wave generation elements that are divided into a plurality of groups, and a control unit that causes the plurality of electromagnetic wave generation elements to oscillate while shifting a timing in units of group. For example, the control unit causes the plurality of electromagnetic wave generation elements to oscillate such that when the number of the plurality of groups is n, an oscillation start timing of the group that performs mth oscillation (m is a natural number equal to or larger than 2 and equal to or smaller than n) is the same timing as or after an oscillation end timing of the group that performs (m-1)th oscillation.
