Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate processors are used to achieve various interfaces, then interface compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The transmission device incorporates multiple operation modes (differential signal mode, three-phase signal mode, single-phase signal mode) within a single processor, enabling one device to perform multiple interface functions. The selector switches between different signal processing paths based on the required interface type, making the single processor universal for various communication standards.
Solution Approach 2:
The transmission device dynamically switches between different operation modes and signal configurations based on the required interface. The selector and control signal generator enable the device to adapt its signal processing behavior in real-time, transitioning between differential, three-phase, and single-phase modes as needed.
2Adaptability or versatility
If multiple separate processors are used to achieve various interfaces, then interface compatibility is improved, but cost increases
Solution Approach 1:
By integrating multiple interface capabilities into a single transmission device, the patent eliminates the need for multiple separate processors. This multi-functional approach reduces component count, simplifies manufacturing, and lowers overall system cost while maintaining compatibility with various interfaces.
3Adaptability or versatility
If multiple separate processors are used to achieve various interfaces, then interface compatibility is improved, but the number of components increases
Solution Approach 1:
The patent merges the functionality of multiple interface-specific processors into a single transmission device. By combining differential signal processing, three-phase signal processing, and single-phase signal processing capabilities in one integrated circuit with selectable modes, the patent reduces the quantity of components while achieving the same interface compatibility.
4Productivity
If three voltage levels are used for data exchange, then data transmission capability is improved, but interface compatibility becomes more difficult
Solution Approach 1:
The transmission device dynamically adapts its voltage level configuration based on the required interface mode. When operating in differential or single-phase modes, it uses two voltage levels, while three-phase mode utilizes three voltage levels. This dynamic adaptation allows the device to maintain high data transmission capability while ensuring compatibility with different interface standards that may require different voltage configurations.
