Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized control systems with cabling are used, then control functionality is achieved, but installation and wiring complexity increases significantly
Solution Approach 1:
The patent replaces the mechanical cabling system with a wireless communication system. Control units communicate with each other and with the central control system via wireless signals, eliminating the need for physical cable connections between components while maintaining full control functionality.
Solution Approach 2:
The patent divides the centralized control system into decentralized intelligent control units, each responsible for specific plant components. These distributed control units operate autonomously and communicate wirelessly, reducing the need for extensive cabling infrastructure while improving system modularity and ease of installation.
2Reliability
If specialized cables and discrete wiring are used for control functions, then reliable control is achieved, but installation effort and cost increase
Solution Approach 1:
The patent substitutes physical cable connections with wireless communication links between control units. This eliminates the need for installing specialized cables and discrete wiring while maintaining reliable control signals transmission through wireless protocols.
Solution Approach 2:
The wireless communication system serves multiple functions simultaneously - control signals, status monitoring, and data exchange - replacing the need for separate specialized cables for different control functions. A single wireless interface handles multiple communication tasks that previously required multiple cable types.
3Productivity
If centralized control systems are used, then comprehensive control is achieved, but commissioning time and cost increase
Solution Approach 1:
The patent segments the control system into independent intelligent control units that can be configured and commissioned separately. Each unit manages specific plant components autonomously, allowing parallel commissioning of different sections rather than requiring sequential system-wide commissioning.
Solution Approach 2:
The intelligent control units are designed to be self-configuring and self-commissioning. They automatically detect their environment, establish wireless connections with neighboring units, and configure themselves without requiring extensive manual setup, thereby dramatically reducing commissioning time and effort.
4Reliability
If extensive cabling is used for safety-related requirements, then safety control is achieved, but system complexity and cost increase
Solution Approach 1:
The patent replaces physical safety wiring with wireless communication links that transmit safety-related control signals. The wireless system incorporates redundancy and error correction mechanisms to ensure safety-critical communications are reliable without requiring complex physical cable installations.
