Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a large adjacent NFC device is implemented, then NFC communication range is improved, but device size constraints and cosmetic acceptability deteriorate
Solution Approach 1:
The NFC circuit is divided into discontinuous segments that can be selectively coupled together. This segmentation allows the NFC device to maintain a compact physical form factor while enabling larger effective coupling ranges when needed, resolving the contradiction between device size and communication range.
Solution Approach 2:
The switch assembly enables dynamic reconfiguration of the NFC circuit segments, allowing the system to adapt between compact and extended configurations based on operational needs. This dynamic capability allows the NFC device to maintain cosmetic acceptability in normal use while providing extended range when required.
2Device complexity
If discontinuous NFC circuit segments are used, then device complexity is reduced, but NFC communication reliability deteriorates
Solution Approach 1:
The circuit is segmented into discrete sections that can be independently managed and selectively connected. This segmentation simplifies the overall circuit design and manufacturing while the switch assembly ensures reliable connections when segments are coupled, maintaining communication stability.
Solution Approach 2:
The switch assembly acts as an intermediary component that reliably connects the discontinuous NFC circuit segments when needed. This intermediary ensures stable electrical connections between segments, maintaining NFC communication reliability despite the discontinuous circuit structure.
3Adaptability or versatility
If NFC circuitry is embedded in carrying cases, then versatility is improved, but manufacturing precision requirements increase
Solution Approach 1:
The NFC circuit is divided into segments that can be manufactured separately and then integrated into the carrying case. This segmentation reduces the precision requirements for embedding, as each segment can be independently positioned and connected using the switch assembly interface.
Solution Approach 2:
The switch assembly provides a dynamic connection mechanism that compensates for manufacturing tolerances in the embedded NFC circuit segments. This allows for easier integration into carrying cases while maintaining reliable electrical connections despite variations in embedding precision.
