Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surgical removal of organs is used for elasticity detection, then measurement precision is improved, but object-affected harmful factors increase and loss of time increases
Solution Approach 1:
The patent replaces the mechanical surgical removal method with an ultrasonic wave-based non-invasive detection system. The ultrasonic device transmits ultrasonic waves through the organ and detects the mechanical vibration responses, allowing elasticity measurement without physical removal or invasion of the organ, thus eliminating harm to the subject while maintaining detection accuracy
Solution Approach 2:
The patent utilizes mechanical vibration principles by inducing and detecting vibrations in the organ using ultrasonic waves. The device measures the organ's elastic properties by analyzing its vibrational response characteristics, replacing the need for surgical removal with a dynamic vibration-based measurement approach that is both non-invasive and precise
2Measurement precision
If surgical removal of organs is used for elasticity detection, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent replaces the time-consuming surgical removal process with immediate ultrasonic wave transmission and detection. The ultrasonic device can perform elasticity measurements in real-time or near real-time by transmitting waves and analyzing the organ's mechanical response, eliminating the lengthy surgical procedure while maintaining measurement precision
Solution Approach 2:
The patent enables preliminary elasticity assessment to be performed quickly without waiting for surgical removal. By using ultrasonic waves to induce and detect mechanical vibrations in the intact organ, the system provides rapid elasticity measurements that can be obtained before any invasive procedures, significantly reducing the overall detection time
3Measurement precision
If surgical removal of organs is used for elasticity detection, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent employs an ultrasonic device that can serve multiple functions: it generates ultrasonic waves for excitation, detects mechanical vibrations through the same or integrated sensors, and processes signals to extract elasticity information. This multi-functional approach consolidates what would otherwise require separate complex systems into a single integrated device, reducing overall complexity while maintaining precision
Solution Approach 2:
The patent uses ultrasonic waves as an intermediary medium to transmit energy through the organ and carry information about its elastic properties. This intermediary approach allows the device to measure elasticity remotely without direct contact or invasion, simplifying the interaction between the detection system and the organ while preserving measurement accuracy
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 fast, accurate, and harmless detection of organ elasticity without surgery, ensuring the detection process is safe and convenient while maintaining high accuracy through stable frequency mechanical vibrations.
Implementation Method 1
a vibration generator, a damping component and a pressure component which are sequentially connected; when a pressure value detected by the pressure component falls into a preset range, an electrical signal is transmitted to the vibration generator by an external electrical signal output device, such that the vibration generator generates a vibration
Implementation Method 2
the mechanical vibration wave generated by the device has a stable frequency due to a reset from the elasticity of the damping component
Implementation Method 3
an ultrasonic wave is transmitted through the ultrasonic probe to the organ to be detected
Implementation Method 4
Since the propagation speed of the ultrasonic wave is far greater than the propagation speed of the mechanical wave, a wave velocity value of the mechanical wave generated from the vibration of the device for generating mechanical vibration is detected through the ultrasonic wave
