Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired sensor devices and BUS lines are used for sensor integration, then measurement and control functions are achieved, but installation costs and electromagnetic compatibility issues increase
Solution Approach 1:
The patent replaces wired mechanical connections with wireless communication technology. Sensor devices transmit measurement signals wirelessly to control devices, eliminating the need for physical cable connections and BUS lines. This substitution resolves the technical contradiction by maintaining reliable sensor integration while dramatically reducing wiring complexity and improving electromagnetic compatibility.
Solution Approach 2:
The patent extracts the communication function from the physical wiring system by implementing wireless transmission capabilities in sensor devices. By taking out the wired connection requirement and replacing it with wireless communication protocols, the system achieves the same integration reliability without the harmful effects of extensive wiring.
2Ease of operation
If extensive wiring and BUS lines are installed for sensor connection, then control functionality is achieved, but maintenance difficulty and installation costs increase
Solution Approach 1:
The patent replaces the mechanical wiring system with wireless communication, allowing control functionality to be maintained while eliminating the maintenance burden of physical connections. Sensor devices can be replaced or repositioned without requiring cable reconfiguration, significantly improving ease of repair and installation.
Solution Approach 2:
The wireless sensor devices autonomously transmit their data without requiring physical connection infrastructure. This self-service capability eliminates the need for manual wiring during installation and maintenance, allowing operators to simply power the devices and have them automatically integrate into the control system.
3Object-affected harmful factors
If wired sensor systems are used, then electromagnetic compatibility can be achieved through shielding, but installation complexity and costs increase
Solution Approach 1:
The patent eliminates the electromagnetic compatibility problem entirely by replacing wired connections with wireless communication. Since there are no physical cables to act as antennas or conduct interference, shielding measures become unnecessary, resolving the technical contradiction by achieving EMC without additional complexity.
Solution Approach 2:
The patent extracts the electromagnetic interference issue from the system by removing all wired connections that could serve as transmission paths for electromagnetic noise. Wireless communication at appropriate frequencies avoids the EMC problems inherent in wired systems, eliminating the need for shielding infrastructure.
