Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of mounted ICs is increased to enhance device functionality, then the device complexity and functionality improve, but the communication speed decreases
Solution Approach 1:
The patent divides the communication system into multiple independent communication lines (first communication line and second communication line), each handling communication with different ICs separately. This segmentation prevents communication congestion that would occur with a shared communication bus, thereby maintaining communication speed while supporting multiple ICs.
Solution Approach 2:
The controller acts as an intermediary that manages multiple independent communication lines between itself and different ICs. By coordinating communications through separate channels rather than a shared bus, the controller enables parallel or interleaved communication sequences that prevent speed degradation despite increased IC count.
2Device complexity
If multiple ICs are connected through a shared communication bus, then device complexity is reduced, but communication efficiency and control accuracy deteriorate
Solution Approach 1:
Instead of using a single shared communication bus, the patent segments the communication infrastructure into multiple dedicated lines. Each communication line is assigned to specific IC pairs, eliminating contention and ensuring that communication efficiency is maintained while the overall device complexity remains manageable through systematic organization.
3Device complexity
If a single communication line is used for all ICs, then the device complexity is minimized, but power consumption increases due to continuous communication overhead
Solution Approach 1:
The patent segments the communication system into multiple dedicated lines, allowing the controller to activate only the specific communication line needed for a given operation. This selective activation reduces unnecessary communication overhead and power consumption compared to maintaining a continuously active shared communication bus that must serve all ICs.
