Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different serial communication protocols are used by electric components, then communication compatibility is improved, but protocol matching complexity increases
Solution Approach 1:
The patent introduces a communication converter as an intermediary device that translates between different serial communication protocols. The converter includes a first communication interface for power line communication and a second communication interface for other serial protocols, automatically handling protocol conversion without requiring manual matching, thus resolving the contradiction between compatibility and complexity
Solution Approach 2:
The communication converter is designed with multi-functionality to handle multiple communication protocols simultaneously. It can interface with different types of electric components using different protocols through a single universal device, eliminating the need for separate protocol matching procedures for each component pair
2Ease of manufacture
If communication converter and electronic parts are arranged in separate packages, then ease of manufacture is improved, but handling and mounting difficulty increases
Solution Approach 1:
The patent combines the communication converter and necessary electronic parts (such as crystal oscillator circuits, filter circuits, pull-up resistors, and bypass capacitors) into a single integrated circuit module package. This unified packaging allows the entire communication interface system to be mounted as one component, significantly simplifying handling and installation while maintaining manufacturing flexibility through standardized production processes
3Ease of repair
If multiple electronic parts are distributed across different circuit boards, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The patent integrates the communication converter and all its required electronic support parts into a single circuit module that functions as one replaceable unit. This modular design maintains ease of repair by allowing the entire communication interface to be replaced as a single component, while simultaneously reducing overall device complexity by consolidating what would otherwise be scattered across multiple circuit boards
