Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing connection technologies are used to connect electrodes to electrical components, then the connection can be established, but the reliability of connection and disconnection is poor
Solution Approach 1:
The system is divided into separate modular components: an electrode connector system with PCB assembly, and an electrical component with electrode. The PCB assembly includes separate contact pads for different electrodes, allowing independent connection and disconnection of each electrode while maintaining overall system reliability.
Solution Approach 2:
The electrode is nested within the electrode clamp, which is part of the electrical component assembly. The PCB assembly is inserted into the electrode connector system housing. This nested structure ensures proper alignment and secure connection, improving reliability while allowing straightforward assembly and disassembly operations.
2Productivity
If existing connection technologies are used, then electrodes can be connected to electrical components, but the process is inefficient for signal collection and transmission
Solution Approach 1:
The PCB assembly is pre-configured with contact pads positioned at specific locations before final assembly. The electrode connector system housing includes pre-formed recesses and alignment features. This preliminary preparation ensures that when components are assembled, electrical connections are established immediately and reliably, improving both productivity and reliability.
Solution Approach 2:
The PCB assembly acts as an intermediary between the electrode and the electrical component. It provides a stable platform with multiple contact pads that can simultaneously connect to multiple electrodes, enabling efficient signal collection while maintaining reliable connections through its rigid structure and controlled impedance traces.
3Reliability
If a stable electrical connection is established between electrodes and PCBs, then signal transmission is reliable, but the connection system becomes more complex
Solution Approach 1:
The electrode clamp, electrical component housing, and connection mechanism are merged into a single integrated electrical component assembly. The PCB assembly is combined with the electrode connector system housing. This merging reduces the number of separate components and interfaces, simplifying the overall system while maintaining stable electrical connections through the integrated design.
