Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If independent actuators are used for transmitting and receiving sensors, then device complexity is reduced, but measurement precision deteriorates due to unsynchronized motion and uneven loading
Solution Approach 1:
The patent combines multiple actuators into a single synchronized actuation system that controls both transmitting and receiving sensors simultaneously. This merging approach ensures uniform loading and synchronized motion while maintaining manageable system complexity through integrated control mechanisms.
Solution Approach 2:
The patent implements feedback mechanisms that monitor the positions and motions of sensors, allowing the actuation system to adjust and synchronize their movements in real-time. This feedback control ensures precise acoustic measurements by maintaining consistent spacing and loading conditions throughout the measurement process.
2Ease of operation
If sensors are moved at different speeds, then ease of operation is improved, but signal repeatability deteriorates due to unrepeatable loading conditions
Solution Approach 1:
The patent employs dynamic actuation control that adjusts sensor speeds and positions in real-time based on measurement requirements. The system maintains synchronized motion through adaptive control algorithms, ensuring repeatable loading conditions while providing operational flexibility for different measurement scenarios.
Solution Approach 2:
Real-time feedback monitoring of sensor positions and velocities enables the system to maintain synchronized movement and consistent loading conditions. The feedback loop detects and corrects any speed variations, ensuring signal repeatability while allowing easy adjustment of measurement parameters.
3Productivity
If sample positioning is not precisely controlled, then manufacturing precision is reduced, but productivity is improved by eliminating positioning feedback requirements
Solution Approach 1:
The patent implements preliminary sample positioning and actuator calibration before measurements begin. This preliminary setup ensures precise sample positioning and synchronized sensor alignment, eliminating the need for complex real-time positioning feedback during actual measurements and maintaining high diagnostic throughput.
Solution Approach 2:
The system uses positioning feedback mechanisms that verify sample placement and sensor alignment before initiating measurements. This feedback control ensures manufacturing precision by confirming correct positioning, while the automated verification process maintains high productivity by quickly validating and proceeding with measurements.

AI summary
One or more aspects of the present disclosure are directed to a synchronized actuation system for holding samples (e.g., battery cells) in place such that ultrasonic sensors can make physical contacts with the samples to transmit and receive acoustic signals across the samples for purposes of making ultrasound measurements of the battery sample. The movement of sensors on both sides of a sample can be synchronized (as opposed to being handled via independent actuators) to improve signal repeatability.
