Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single antenna is used for contactless communication, then the device complexity is reduced, but the reliability of contactless communication deteriorates
Solution Approach 1:
The contactless communication system is segmented into multiple independent antenna units (first antenna and second antenna) that can be independently controlled and selected. The controller divides the antenna selection task by evaluating signal strengths from different antennas and choosing the optimal one for communication, thereby improving reliability without requiring a completely complex new system architecture.
2Reliability
If multiple antennas are used for contactless communication, then the signal reception reliability is improved, but the device complexity increases
Solution Approach 1:
The antenna system is made dynamic through the controller's ability to selectively activate and switch between the first and second antennas based on real-time signal strength evaluation. This dynamic selection process allows the system to adapt to different communication conditions, maintaining high reliability while managing complexity through intelligent control rather than static multi-antenna configuration.
Solution Approach 2:
The controller implements a feedback mechanism by continuously monitoring and comparing signal strengths from multiple antennas. Based on this feedback information, the controller automatically selects the antenna with the strongest signal for communication, ensuring optimal reception reliability while keeping the system complexity manageable through automated decision-making.
3Reliability
If a single antenna is used, then the manufacturing cost is reduced, but the contactless communication performance deteriorates
Solution Approach 1:
The communication system is segmented into multiple antenna components that can be manufactured using standard antenna production processes. By dividing the system into separate antenna units (first antenna and second antenna) with standard configurations, the manufacturing complexity for each individual antenna remains simple and cost-effective, while the overall system performance is enhanced through the multi-antenna architecture.
