Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate communication mechanism is added to the probe positioning device, then signal transmission reliability is improved, but device complexity increases
Solution Approach 1:
The signal means is integrated into the carrier part that also holds the probe, combining communication and positioning functions in a single structure. This merging eliminates the need for separate communication mechanisms while maintaining signal transmission reliability through the continuous signal wire connection.
Solution Approach 2:
The carrier part serves multiple functions: it holds the probe, provides the signal means for communication, and acts as the insertion mechanism. This multi-functionality reduces overall device complexity while ensuring reliable signal transmission through the integrated continuous wire connection.
2Device complexity
If mechanical connection methods are used for signal transmission, then device complexity is reduced, but mechanical disruptions may occur
Solution Approach 1:
The patent replaces complex mechanical connection systems with a simpler continuous signal wire connection. The wire is routed through the carrier part and connection elements in a way that eliminates complex mechanical joints, reducing the risk of mechanical disruptions while maintaining simplicity.
Solution Approach 2:
The signal wire is pre-routed and secured within the carrier part structure before insertion. This preliminary arrangement ensures that the wire maintains continuous contact without requiring complex mechanical adjustments during operation, preventing mechanical disruptions while keeping the system simple.
3Device complexity
If the signal means is integrated into the carrier part, then device complexity is reduced, but power transmission may be affected
Solution Approach 1:
The signal means and power source are integrated into the carrier part, combining signal transmission and power supply functions in one component. This integration reduces device complexity while ensuring adequate power transmission through the same carrier structure that carries the signal wire.
Solution Approach 2:
The carrier part acts as an intermediary that simultaneously transmits both signals and power to the probe. By serving as a common medium for both functions, it simplifies the overall device structure while maintaining effective power transmission without requiring separate dedicated power delivery mechanisms.
