Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If couplant liquid is used to improve ultrasonic wave propagation, then detection accuracy is improved, but inspection time increases due to application and removal steps
Solution Approach 1:
The invention extracts the beneficial function of the couplant liquid (improving ultrasonic wave propagation) while eliminating its harmful aspects (time-consuming application and removal). This is achieved by transferring the couplant liquid's function to a solid propagation member that can be easily attached and detached, providing the same ultrasonic coupling effect without requiring liquid application steps.
Solution Approach 2:
The solid propagation member acts as an intermediary between the ultrasonic wave source and the inspection surface. Instead of using couplant liquid as the intermediary medium, the solid propagation member provides a stable, reusable interface that maintains ultrasonic wave transmission while eliminating the need for liquid application and removal processes.
2Measurement precision
If couplant liquid is used to improve ultrasonic wave propagation, then detection accuracy is improved, but the object's surface can be altered
Solution Approach 1:
The invention extracts the beneficial function of the couplant liquid (improving ultrasonic wave propagation) while eliminating its harmful aspect (surface alteration). The solid propagation member provides the necessary coupling function without requiring contact with the object surface that would cause alteration or contamination.
Solution Approach 2:
The solid propagation member serves as an intermediary that prevents direct contact between the inspection system and the object surface. This intermediary approach maintains detection accuracy while avoiding the harmful effect of surface alteration that occurs with liquid couplants.
3Measurement precision
If couplant liquid is used to improve ultrasonic wave propagation, then detection accuracy is improved, but detection accuracy reduces when foreign matter damages the liquid
Solution Approach 1:
The solid propagation member is designed as a disposable or easily replaceable component. When contaminated by foreign matter, it can be discarded or replaced rather than cleaned and reused, ensuring consistent detection accuracy without the reliability issues associated with maintaining liquid couplant quality.
Solution Approach 2:
The solid propagation member acts as a protected intermediary that prevents foreign matter from directly contaminating the ultrasonic coupling interface. Its solid structure resists contamination better than liquid couplants, and when damaged, it can be replaced to restore detection accuracy.
4Loss of time
If a solid propagation member is used instead of couplant liquid, then inspection time is reduced, but ultrasonic wave propagation may be insufficient without proper coupling
Solution Approach 1:
The solid propagation member serves as an effective intermediary that maintains ultrasonic wave propagation capability while enabling quick attachment and detachment. Its material properties and interface design ensure proper acoustic coupling without requiring the time-consuming steps associated with liquid couplants.
Solution Approach 2:
The invention changes the physical state parameter from liquid to solid, and optimizes the material properties (acoustic impedance, surface finish, elasticity) of the solid propagation member to ensure effective ultrasonic wave propagation. This parameter optimization maintains detection accuracy while reducing inspection time.
