Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate ultrasonic probe devices are used for different frequency areas, then diagnostic coverage and versatility are improved, but device complexity and user convenience deteriorate
Solution Approach 1:
The patent combines multiple ultrasonic probe modules with different frequency characteristics into a single integrated device. The device includes a first ultrasonic probe module and a second ultrasonic probe module, allowing users to access different frequency ranges (e.g., high-frequency and low-frequency probes) without needing separate devices. This merging approach resolves the contradiction by consolidating multiple functions into one device, improving versatility while reducing the number of devices required.
Solution Approach 2:
The ultrasonic device is designed with multi-functionality by incorporating probe modules that can operate across different frequency areas. The device can perform both high-frequency diagnostics (for superficial structures) and low-frequency diagnostics (for deeper structures) using a single apparatus. This universal design allows one device to replace multiple specialized devices, addressing the contradiction between versatility and device complexity.
2Measurement precision
If different probes are used for different diagnostic applications, then diagnostic precision is improved, but ease of operation deteriorates
Solution Approach 1:
By merging multiple probe modules into a single device with a unified control system, the patent eliminates the need for users to physically handle and switch between separate probe devices. The control module can selectively activate different probe modules based on diagnostic requirements, maintaining diagnostic precision while significantly improving ease of operation. Users simply operate one device to access multiple probe types.
3Reliability
If a single ultrasonic probe is designed for a specific frequency range, then performance for that frequency is optimized, but adaptability to different diagnostic needs deteriorates
Solution Approach 1:
The patent segments the ultrasonic probe system into multiple independent probe modules, each optimized for specific frequency ranges. The first ultrasonic probe module can be designed for high-frequency applications while the second module handles low-frequency applications. Each segment maintains its frequency-specific optimization, yet the overall system achieves broad adaptability through the combination of segmented modules controlled by a unified control system.
