Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate processors are used to support different communication interfaces, then interface compatibility and functionality are improved, but device complexity and cost increase
Solution Approach 1:
The transmitter is designed with a universal architecture that can operate in multiple transmission modes (differential mode with two output terminals and three-phase mode with three output terminals) using the same basic circuit structure. The transmitting sections can dynamically configure their output based on the required interface type, eliminating the need for separate processors for different communication standards.
2Adaptability or versatility
If multiple separate processors are used to support different communication interfaces, then interface compatibility and functionality are improved, but cost increases
Solution Approach 1:
By implementing a single transmitter that can function as both a differential transmitter and a three-phase transmitter through configurable transmitting sections, the design eliminates the need to manufacture and stock multiple different processor types, thereby reducing manufacturing costs and inventory requirements.
Solution Approach 2:
The invention merges the functionality of multiple separate transmitters (differential and three-phase) into a single unified transmitter device. This consolidation reduces the total component count, simplifies the bill of materials, and lowers overall manufacturing costs while maintaining full interface compatibility.
3Productivity
If complex communication systems are used to manage increasing data exchange, then data exchange capability is improved, but configuration complexity increases
Solution Approach 1:
The transmitter is divided into independent transmitting sections (first transmitting section and second transmitting section) that can be individually configured and activated. Each section handles specific transmission tasks, allowing the system to scale data exchange capability by enabling or disabling sections rather than increasing overall system complexity.
