Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parallel communication is used to control solenoid valves, then control reliability is improved, but the number of signal lines increases significantly
Solution Approach 1:
The system is divided into multiple solenoid valve blocks (first block, second block, etc.), each controlled by dedicated block selection lines. This segmentation allows the control system to manage numerous valves through hierarchical addressing rather than requiring individual parallel signal lines for each valve, thus reducing overall signal line complexity while maintaining reliable control.
Solution Approach 2:
The patent transitions from a single-dimension parallel communication approach to a multi-dimensional control structure by introducing block selection lines that operate in a different dimension. This allows the system to select which block of valves to control first, then use serial communication within that block, effectively adding a selection dimension that reduces the total number of required signal lines.
2Device complexity
If serial-to-parallel conversion circuits are connected in series, then the number of signal lines is reduced, but response delays occur
Solution Approach 1:
The solenoid valve control system is segmented into multiple independent blocks, with each block containing solenoid valves and their corresponding operating circuits. This segmentation allows the control unit to selectively activate only the required block using block selection lines, rather than processing signals through all conversion circuits in series, thereby reducing response delay while maintaining signal line efficiency.
Solution Approach 2:
The control unit preliminarily selects the target solenoid valve block using block selection lines before initiating serial communication within that block. This preliminary selection action prepares the system in advance, allowing the selected block to be ready for immediate control signal processing, thus reducing overall response time compared to sequential processing through all blocks.
3Adaptability or versatility
If a large number of solenoid valves are controlled, then system functionality is improved, but the number of signal lines increases
Solution Approach 1:
The solenoid valve system is divided into multiple blocks, where each block can be independently controlled. This segmentation enables the system to handle a large total number of valves by organizing them into manageable groups, each accessible through dedicated block selection lines and internal transfer lines, thus scaling functionality without proportionally increasing signal line complexity.
Solution Approach 2:
The block selection lines and transfer lines serve multiple functions: they selectively activate different blocks and route control signals to the appropriate solenoid valves within selected blocks. This multi-functionality allows the same signal lines to control numerous valves across different blocks, enhancing system versatility without requiring a separate signal line for each valve.

AI summary
In a solenoid valve control device, a plurality of solenoid valve blocks are connected in series with respect to a solenoid valve control unit. A solenoid valve operating circuit of a given solenoid valve block, to which a block selection signal from a block selection line is supplied, operates plural solenoid valves of the same given block, based on the block selection signal.
