Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If screen-based support technique is used to guide user operation, then user operation accuracy is improved, but user completeness of maintenance work deteriorates due to omission of operations in complex maintenance work
Solution Approach 1:
The system implements feedback by detecting user operations through sensors and comparing them with the required maintenance procedure steps. The control unit receives detection signals from sensors that monitor user actions, determines whether the detected operation matches the expected step, and provides appropriate feedback (proceed to next step or request correction). This closed-loop feedback mechanism ensures both operational accuracy and completeness of maintenance tasks.
Solution Approach 2:
The maintenance guidance system operates autonomously by automatically detecting user operations through sensors, comparing them with required procedures, and controlling the flow of maintenance steps without requiring external intervention. The system self-manages the guidance process, detecting operations, determining correctness, and progressing through maintenance steps independently, reducing reliance on external manual verification.
2Reliability
If complex maintenance procedure is implemented, then maintenance completeness is improved, but ease of operation deteriorates due to complexity of user work
Solution Approach 1:
The maintenance procedure is segmented into discrete steps, with each step associated with specific detection conditions. The control unit divides the complex maintenance task into manageable segments, guiding the user through one step at a time. Each segment corresponds to a specific operation that can be detected and verified independently, making the overall complex procedure easier to follow and execute.
Solution Approach 2:
The system performs preliminary actions by pre-defining the complete maintenance procedure and detection conditions before execution. The control unit has the entire maintenance protocol prepared in advance, with all detection conditions and expected operations predetermined. This allows the system to guide the user through pre-planned steps, reducing the cognitive load during actual maintenance execution.
3Ease of operation
If automated detection and control is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it displays maintenance guidance, detects user operations through sensor signals, determines whether detected operations match required steps, controls the flow of maintenance procedures, and manages error handling. This multi-functional control unit reduces the need for separate dedicated components for each function, thereby managing device complexity while maintaining ease of operation.
Solution Approach 2:
Sensors act as intermediaries between the user's physical operations and the control unit's digital processing. The sensors detect physical user actions and convert them into detection signals that the control unit can process. This intermediary layer simplifies the interface between human operation and automated control, making the system easier to operate while managing the complexity of automated detection and control mechanisms.
