Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electronic device uses traditional communication methods, then device complexity is reduced, but user interface functionality and short-range wireless communication capabilities are limited
Solution Approach 1:
The electronic device incorporates multiple antenna parts with different functions: a first antenna part for coordinate sensing and a second antenna part for data communication. This multi-functionality allows a single device to perform both UI extension functions and NFC communication, resolving the contradiction between enhanced adaptability and device complexity
Solution Approach 2:
The antenna system is segmented into distinct functional components: a first antenna part dedicated to coordinate sensing sensor communication and a second antenna part dedicated to data communication antenna communication. This segmentation allows each antenna to be optimized for its specific function while maintaining overall system manageability
2Adaptability or versatility
If an electronic device adds multiple antenna parts for extended functionality, then user interface functionality and communication capabilities are enhanced, but device complexity increases
Solution Approach 1:
The electronic device integrates multiple antenna parts that serve different communication purposes: the first antenna part handles coordinate sensing while the second antenna part handles data communication. This multi-functional design enhances communication capabilities without requiring separate dedicated devices for each function
Solution Approach 2:
The patent introduces a controller that manages and coordinates the multiple antenna parts. This intermediary component simplifies the overall system complexity by providing centralized control logic, allowing the device to handle multiple communication functions through a unified management structure
