Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrode equipment is designed with fixed polarity assignment, then the structure is simple and easy to manufacture, but the polarity may mismatch when attached in incorrect direction
Solution Approach 1:
The electrode equipment dynamically adjusts its polarity assignment based on the detected attachment direction. The control unit switches between first and second polarity assignments depending on whether the sensor detects correct or incorrect attachment orientation, allowing the system to adapt to different attachment scenarios rather than relying on a fixed polarity configuration.
Solution Approach 2:
The system incorporates a sensor that provides feedback about the attachment direction to the control unit. This feedback mechanism enables the control unit to determine the attachment orientation and automatically adjust the polarity assignment accordingly, ensuring correct polarity matching without requiring complex mechanical prevention structures.
2Reliability
If a sensor and control system are added to detect attachment direction and adjust polarity, then polarity matching reliability is improved, but the device complexity increases
Solution Approach 1:
The electrode equipment performs self-correction by automatically detecting its own attachment direction and adjusting its polarity assignment accordingly. The system serves itself by eliminating the need for external verification or manual reconfiguration, reducing the burden on users while maintaining simplicity in the overall system architecture.
Solution Approach 2:
The system changes the electrical parameter (polarity assignment) based on the detected attachment direction. By switching between different polarity assignments (first and second assignments) according to sensor feedback, the system maintains reliability without requiring complex hardware modifications, leveraging software-based parameter adjustment instead.
3Ease of operation
If fixed polarity assignment is used, then the device is easier to operate, but the equipment may be operated incorrectly when attached in wrong direction
Solution Approach 1:
The sensor acts as an intermediary between the physical attachment state and the electrical polarity assignment. It translates the mechanical attachment direction into detectable signals that the control unit can process, automatically mediating the connection between user action and system response without requiring the user to understand or verify polarity alignment.
