Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna pole is arranged on the outside of the measuring unit for high radiation power, then signal transmission quality is improved, but the measuring unit requires additional connections for charging which increases device complexity
Solution Approach 1:
The antenna pole is designed to serve dual functions: transmitting high-frequency measurement signals and conducting low-frequency charging current. The separating switch enables the antenna pole to be universally used for both signal transmission and energy storage device charging, eliminating the need for separate charging connections and reducing device complexity while maintaining external accessibility for high radiation power
2Reliability
If separate connections are provided for signal transmission and charging, then functional reliability is improved, but the measuring unit size increases compromising compact design
Solution Approach 1:
The antenna pole serves as a universal connection point for both high-frequency signal transmission and low-frequency charging operations. The separating switch enables this multi-functionality by directing different frequency signals through the same physical connection, maintaining functional reliability while preserving the compact design of the measuring unit
3Device complexity
If the antenna pole is used for both signal transmission and charging, then device complexity is reduced, but signal interference between high-frequency and low-frequency signals may occur
Solution Approach 1:
The separating switch dynamically directs signals based on frequency: high-frequency measurement signals are routed to the antenna pole for transmission, while low-frequency charging current is routed to the energy storage device. This dynamic switching prevents signal interference by ensuring that only one type of signal flows through the antenna pole at any given time, maintaining low device complexity while eliminating harmful interference
