Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC communication is established between electronic devices with varying antenna sizes and locations, then communication capability is enabled, but recognition rate becomes inconsistent
Solution Approach 1:
The system performs preliminary actions by storing antenna location information in advance and providing guidance to users before the actual NFC communication attempt. The electronic device acquires and stores antenna location data, then uses this pre-acquired information to guide optimal device placement, ensuring reliable recognition despite variations in antenna configurations across different devices
Solution Approach 2:
The patent introduces an intermediary guidance mechanism that mediates between the electronic device and NFC reader. This guidance system (displaying optimal placement locations) acts as an intermediary to bridge the gap caused by varying antenna configurations, helping users position devices correctly to achieve reliable communication
2Adaptability or versatility
If antenna size and location vary across different vehicles and devices, then device compatibility is improved, but communication reliability deteriorates
Solution Approach 1:
The system applies local quality by providing location-specific guidance for NFC communication. Instead of using a uniform approach, the electronic device determines and displays specific optimal placement locations based on the particular antenna configuration of the target device, tailoring the communication approach to each local situation
Solution Approach 2:
The patent utilizes parameter changes by adjusting communication parameters based on antenna location information. The system acquires antenna location data and uses this information to determine optimal communication parameters and device placement, adapting the communication process to match the specific configuration of each device pair
3Reliability
If optimal NFC parameters are used, then connection sensitivity is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by automatically acquiring and utilizing antenna location information to determine optimal communication parameters. The electronic device performs these optimization actions autonomously without requiring complex user intervention or manual configuration, achieving improved connection sensitivity while keeping the user interface simple
