Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ultrasound systems are used, then color Doppler ultrasound data collection capability is provided, but device complexity and cost increase
Solution Approach 1:
The patent extracts the color Doppler data collection functionality from the complex conventional ultrasound system and implements it through a simplified ultrasound-on-a-chip device with a targeted region identifier overlay, separating the essential data collection capability from the system complexity
Solution Approach 2:
The patent creates a simplified copy of the ultrasound imaging function using ultrasound-on-a-chip technology instead of conventional systems, maintaining the color Doppler capability while reducing overall system complexity through alternative implementation
2Adaptability or versatility
If conventional ultrasound systems are used, then color Doppler ultrasound data collection capability is provided, but cost increases
Solution Approach 1:
The patent employs disposable or low-cost ultrasound-on-a-chip devices instead of expensive conventional ultrasound systems, making the advanced color Doppler capability accessible to more medical facilities while reducing the cost barrier to entry
Solution Approach 2:
The patent creates an affordable copy of the ultrasound imaging function through chip-based technology, replicating the essential color Doppler capability at a lower cost than conventional systems
3Device complexity
If existing ultrasound-on-a-chip devices are used, then device complexity is reduced, but ease of operation deteriorates due to lack of intuitive controls
Solution Approach 1:
The patent introduces a targeted region identifier overlay as an intermediary visual element between the user and the ultrasound data collection process, providing intuitive visual feedback and control guidance that simplifies operation while maintaining low device complexity
Solution Approach 2:
The patent utilizes visual indicators and overlays on the display to provide intuitive feedback during data collection, improving ease of operation through visual cues that guide user interaction with the simplified device
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible and intuitive collection of color Doppler ultrasound data, reducing the complexity of control options and making advanced ultrasound imaging more accessible and user-friendly, particularly with ultrasound-on-a-chip devices.
Implementation Method 1
When pulses of ultrasound are transmitted into tissue (e.g., by using a pulser in an ultrasound imaging device), sound waves are reflected off the tissue, with different tissues reflecting varying degrees of sound.
Implementation Method 2
configuring the ultrasound device to collect color Doppler ultrasound data based on the target region identifier
Data Source
AI summary
Aspects of the technology described herein include a processing device configured to display, on a touch-sensitive display screen of a processing device in operative communication with an ultrasound device, an ultrasound image, a target region identifier superimposed on the ultrasound image, a first icon located on the target region identifier, and a second icon located on the target region identifier. The first icon is configured to control the height of the target region identifier and the angle of two opposite sides of the target region identifier. The second icon is configured to control the width of the target region identifier. The processing device is configured to configure the ultrasound device to collect color Doppler ultrasound data based on the region of the ultrasound image covered by the target region identifier and the angle of the two opposite sides of the target region identifier.
