Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving chips are cascaded with fixed input/output port configurations, then the connection between chips can be established, but the wiring complexity increases and signal transmission resistance increases
Solution Approach 1:
The patent applies the dynamics principle by making the port configuration dynamic rather than fixed. Each driving chip can automatically identify its connection status and dynamically switch port functions between input and output modes based on real-time connection detection, eliminating the need for complex predetermined wiring arrangements.
Solution Approach 2:
The patent changes the operational parameters of the signal ports from fixed states to variable states. The port configuration can switch between different modes (input/output) based on detected connection conditions, allowing the system to adapt to different cascading arrangements without increasing wiring complexity.
2Reliability
If driving chips are cascaded with fixed input/output port configurations, then the connection between chips can be established, but signal transmission resistance increases
Solution Approach 1:
The dynamic port configuration allows the system to optimize signal transmission paths in real-time. By detecting actual connection status and dynamically adjusting which ports function as inputs or outputs, the system avoids suboptimal signal paths that would increase transmission resistance.
Solution Approach 2:
The patent implements feedback mechanisms where each chip detects connection status and uses this information to adjust its port configuration. This feedback loop ensures that signal transmission occurs through optimal paths, minimizing resistance and improving transmission quality.
3Reliability
If driving chips are cascaded with fixed input/output port configurations, then the basic functionality can be achieved, but the cascading efficiency decreases
Solution Approach 1:
The dynamic port configuration enables rapid adaptation to different cascading scenarios. Chips can automatically configure themselves when connected, eliminating manual setup and accelerating the cascading process while maintaining full functionality.
Solution Approach 2:
Each driving chip performs self-configuration based on detected connection status. The chips automatically determine their role in the cascade (input or output port) without external intervention, improving cascading efficiency while ensuring proper functionality.
