Engineering Contradiction Analysis
1Measurement precision
If conventional ultrasonic wave analysis methods are used to detect muscle changes, then long-term muscle morphology changes can be quantified, but instant muscle contraction responses and muscle function cannot be obtained
Solution Approach 1:
The patent combines an electric stimulus device with an ultrasonic wave pulse echo device to create an integrated system that can simultaneously apply electric stimuli and detect muscle contraction responses using ultrasonic waves, enabling both morphology and function analysis
Solution Approach 2:
The patent replaces complex mechanical imaging systems (CT, MRI) with a simpler ultrasonic wave-based detection system that uses acoustic waves to measure muscle deformation, achieving muscle function analysis without requiring complex equipment
2Reliability
If electric stimuli are applied to analyze muscle function, then muscle contraction characteristics can be measured, but the measurements are affected by variations in input conditions and environmental factors
Solution Approach 1:
The patent specifies precise parameter settings for the electric stimulus (short pulse duration, specific frequency) and ultrasonic wave transmission to standardize the measurement conditions, reducing the influence of environmental and physical condition variations on the results
3Measurement precision
If detailed input conditions of electric stimuli are defined to accurately analyze muscle function, then measurement accuracy improves, but the complexity of the analysis system increases
Solution Approach 1:
The patent pre-defines the electric stimulus parameters (short pulse, specific frequency) and ultrasonic wave transmission settings before the measurement process, establishing standardized protocols that simplify the analysis system while ensuring accurate and reliable muscle function assessment
