Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated component is added to suppress electrostatic discharge in the control board, then ESD protection is improved, but the size of the hydraulic pressure control unit increases
Solution Approach 1:
The patent makes the sensor board serve dual functions: its original sensing function plus ESD protection function. The sensor board is electrically connected to both the control board and the base body, allowing it to detect hydraulic pressure signals while also providing an ESD discharge path from the control board to the base body, thereby protecting the control board without requiring additional components.
Solution Approach 2:
The patent combines the ESD protection function with the existing sensor board structure. By integrating the ESD discharge path through the sensor board's electrical connections to the base body, the invention merges two functions (sensing and ESD protection) into a single component, avoiding the need for separate ESD protection components that would increase unit size.
2Reliability
If the sensor board is electrically connected to the base body via casing, then ESD discharge path is established, but manufacturing complexity increases
Solution Approach 1:
The sensor board automatically provides ESD protection through its own electrical connections. The sensor board is electrically connected to the control board for signal reception and to the base body through the casing for ESD discharge. This self-service approach allows the sensor board to protect the control board without requiring external ESD protection components or complex additional wiring, simplifying the overall manufacturing process.
