Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed radiation distribution is used in the treatment chamber, then the microwave treatment device is simple to operate, but it cannot be adapted to different objects or treatment procedures

Engineering Contradiction:
Improveadaptability to different objectsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The microwave emission device is divided into multiple individually controllable emitters arranged in an array. Each emitter can be controlled independently to vary the radiation distribution, allowing adaptation to different objects without mechanical modifications to the overall device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The radiation distribution is made dynamically adjustable through electronic control of individual emitter activation and power levels. This allows the system to adapt to different treatment requirements by changing which emitters are active and at what power, rather than requiring physical reconfiguration.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the microwave emitter is modified to achieve different radiation distributions, then adaptability to different objects is improved, but the effort required for modification is high

Engineering Contradiction:
Improveradiation distribution adaptabilityVSAvoidmodification effort
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The emitter array is designed with multiple independently controllable elements from the outset. This segmentation allows different radiation distributions to be achieved by simply changing which segments (emitters) are activated and at what power levels, eliminating the need for physical modifications to the device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different radiation distributions are achieved by changing operational parameters (which emitters are active and their respective power levels) rather than changing physical parameters (emitter arrangement or orientation). This allows rapid adaptation without mechanical work.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If a resonator treatment chamber is used, then consistent radiation distribution is achieved, but the system cannot be easily adapted to varying treatment requirements

Engineering Contradiction:
Improveradiation distribution consistencyVSAvoidtreatment procedure adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The resonator chamber is paired with a segmented emitter array where individual emitters can be controlled independently. This allows the system to maintain the consistent radiation distribution benefits of the resonator while adapting to different treatments by selectively activating specific emitter segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the treatment chamber can receive different radiation intensities by selectively activating specific emitters in the array. This allows local customization of radiation distribution within the resonator chamber to suit different treatment requirements while maintaining overall system consistency.

Inventive Principle:
Principle #3Local quality
