Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manufacturers continue to produce legacy communication profile component products to ensure normal operation of industrial fields and substations, then compatibility and reliability are maintained, but production cost increases
Solution Approach 1:
The communication apparatus is designed to provide functions of multiple dedicated communication profile components (MiCom Px20, Px30, Px40, Sepam 20/40/80, Vamp 50) through a single multi-functional device. The configuration module allows selecting different operational modes corresponding to different legacy components, enabling one device to replace multiple specialized devices while maintaining compatibility with existing systems.
2Adaptability or versatility
If users continue to purchase legacy communication profile component products to ensure normal operation of industrial fields and substations, then system compatibility is maintained, but operating cost increases
Solution Approach 1:
The communication apparatus provides multi-functional capabilities to replace multiple legacy communication profile components with a single device. By configuring the apparatus to operate in different modes corresponding to different legacy components, users can maintain system compatibility while reducing the number of devices needed, thereby lowering operating costs.
Solution Approach 2:
The patent combines the functions of multiple dedicated communication profile components into a single communication apparatus. The configuration module integrates different operational modes for MiCom Px20, Px30, Px40, Sepam 20/40/80, and Vamp 50 components, merging their functionalities into one unified device that can be deployed to replace multiple separate legacy devices.
3Adaptability or versatility
If communication apparatus provides functions of multiple dedicated communication profile components, then versatility and adaptability improve, but device complexity and code redundancy increase
Solution Approach 1:
The communication apparatus is segmented into distinct functional modules: a configuration module for selecting operational modes, a management module for controlling operations, and a communication function module for executing communication tasks. This segmentation allows the system to provide multiple functions while maintaining organized, manageable code structures that reduce redundancy.
Solution Approach 2:
The communication apparatus employs dynamic configuration where the operational parameter can be changed to switch between different dedicated communication profile component functions. The management module dynamically selects and activates the appropriate communication function module based on the configured operational parameter, allowing the system to adapt its behavior without requiring separate hardwired configurations for each mode.
