Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional electronic device uses a fixed power supply connection mode (either common or individual power supply), then the device structure is simple, but the adaptability to different power supply scenarios is limited
Solution Approach 1:
The power terminal is divided into two distinct types: common power terminals (for shared power supply) and individual power terminals (for separate power supplies). This segmentation allows the device to support multiple power supply connection modes without increasing overall structural complexity, as each terminal type has a dedicated function.
Solution Approach 2:
The device is designed with dual power terminal capabilities, making it universally compatible with both common power supply configurations and individual power supply configurations. The same device structure can adapt to different power supply scenarios by selecting appropriate terminal connections, eliminating the need for model-specific designs.
2Reliability
If multiple power supplies are used for different processing circuits, then the reliability and availability of the system is improved, but the number of required power supplies and wiring complexity increases
Solution Approach 1:
The device enables dynamic selection of power supply modes (common or individual) based on system requirements. This dynamic adaptability allows the system to optimize between reliability (using individual power supplies when needed) and simplicity (using common power supply when sufficient), without being locked into a fixed configuration.
Solution Approach 2:
The common power terminals and individual power terminals serve as intermediaries that facilitate flexible power distribution. By providing dedicated terminal types for each power supply mode, the device simplifies the connection process and reduces wiring complexity compared to a universal terminal design that would require complex internal switching.
3Device complexity
If a single common power supply is used for all processing circuits, then the wiring is simplified, but the system reliability decreases when power supply failure occurs
Solution Approach 1:
The power terminal is segmented into common power terminals and individual power terminals, allowing the system to physically separate power supply paths when needed. This segmentation enables independent power supply connections for different processing circuits, providing redundancy without complicating the basic terminal structure.
Solution Approach 2:
The system can change its power supply configuration parameter from a single common supply mode to multiple individual supply modes based on reliability requirements. This parameter change is achieved through the dual terminal design, which accommodates different connection topologies without requiring structural modifications.
