Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional microwave treatment apparatuses use fixed emitting portions, then the device structure is simple, but it is difficult to properly control microwave irradiation and achieve local heating or uniform heating
Solution Approach 1:
The microwave emitting system is divided into multiple independent emitting portions (antennas), each capable of being individually positioned and controlled. This segmentation allows precise control of microwave irradiation at different locations, enabling local heating and uniform heating through coordinated positioning of multiple emitting portions.
Solution Approach 2:
The emitting portions are made movable through robotic arms, allowing dynamic repositioning during microwave treatment. This dynamic capability enables the system to adapt emitting portion positions to achieve desired heating patterns, resolving the contradiction between control precision and structural simplicity.
2Measurement precision
If multiple emitting portions are used to achieve local heating, then heating precision is improved, but device complexity and control difficulty increase
Solution Approach 1:
The system incorporates temperature measurement means and control means that use temperature feedback to automatically adjust emitting portion positions and microwave power. This feedback mechanism simplifies operation by eliminating manual control complexity, allowing the system to automatically achieve precise heating at target locations.
Solution Approach 2:
Manual positioning and control operations are replaced with automated robotic arms and computer-controlled systems. The robotic arms precisely position emitting portions based on control signals, substituting complex manual mechanical operations with automated control systems that improve both precision and ease of operation.
3Temperature
If emitting portions are fixed in position, then device complexity is low, but it is difficult to concentrate electrical fields or provide uniform electrical field distribution
Solution Approach 1:
The emitting system is segmented into multiple independently controllable emitting portions that can be positioned at different locations. By coordinating the positions of these segmented emitting portions, the system can concentrate electrical fields at specific points or distribute them uniformly across a region, achieving desired temperature patterns.
Solution Approach 2:
The system changes the positional parameters of emitting portions dynamically to control electrical field distribution. By adjusting the positions of emitting portions, the system can transform the electrical field pattern from fixed and non-uniform to controllable and uniform, or concentrate it at specific points for local heating.
