Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional SAR control method employs a sensor kept at a distance from the antenna clearance zone, then the antenna efficiency is maintained, but the device requires extra space and the sensor cannot effectively sense SAR in the radiation zone
Solution Approach 1:
The patent combines the SAR sensing function and antenna receiving function into a single integrated structure. The sensing component is coupled to the first antenna component to additionally act as a second antenna component, eliminating the need for separate sensor deployment space while maintaining effective SAR detection in the radiation zone.
Solution Approach 2:
The sensing component serves dual functions: it acts as both a SAR sensing element and a second antenna component for wireless signal reception. This multi-functionality allows the device to perform SAR control and communication without requiring additional space for separate components.
2Object-affected harmful factors
If the sensor is placed far from the antenna, then there is enough space for the sensor, but the user may be exposed to hazardous electromagnetic radiation in the radiation zone
Solution Approach 1:
By merging the sensing component with the antenna structure, the system can monitor electromagnetic radiation levels in the radiation zone up close without requiring separate sensor deployment space, thereby protecting users from hazardous exposure while maintaining compact device design.
3Volume of moving object
If the device becomes more compact, then portability is improved, but the space available for deploying the sensor and clearance zone decreases
Solution Approach 1:
The integration of the sensing component with the antenna structure eliminates the need for separate clearance zones and sensor deployment space, enabling compact device design while maintaining effective SAR sensing capability.
Solution Approach 2:
The sensing component performs both SAR sensing and antenna functions, allowing the device to maintain compact dimensions without sacrificing sensing functionality that would otherwise require additional space.
