Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If type plates are used for component identification, then identification is possible, but reading becomes very complex and cumbersome in large systems
Solution Approach 1:
The patent replaces the mechanical/visual reading process of type plates with an electronic data transmission system. The modulator device converts identification data into modulated signals that can be read electronically, substituting the manual visual inspection process with an automated electronic reading mechanism.
Solution Approach 2:
The patent introduces a modulator device as an intermediary between the identification data stored in the valve and the control device. This modulator converts the identification data into modulated control signals that can be transmitted through the existing control lines, serving as a mediator that enables data transmission without direct connection.
2Ease of operation
If wireless transmission of identification data is implemented, then reading becomes easier, but additional components and lines are required
Solution Approach 1:
The patent makes the existing control lines serve dual functions: actuating the electromagnetic valve and transmitting identification data. The control lines are designed to be universal, handling both power/control signals and data transmission, thereby eliminating the need for separate data transmission lines.
Solution Approach 2:
The patent merges the data transmission function with the existing control system. The modulator device combines the identification data with the control signals, and both are transmitted through the same control lines, merging two functions into a single integrated system.
3Loss of information
If additional lines are installed for data transmission, then data can be transmitted, but system complexity and installation effort increase
Solution Approach 1:
The control lines are designed to perform multiple functions simultaneously - actuating the electromagnetic valve and transmitting identification data. This multi-functionality eliminates the need for additional installation of separate data lines, reducing installation effort while maintaining data transmission capability.
