Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the transducer is fixed to a treatment part of one treatment depth, then the structure is simple, but the cartridge needs to be replaced to perform treatment at different depths, complicating the procedure and extending treatment time
Solution Approach 1:
The transducer is made movable along the ultrasound propagation direction through a moving device that includes a moving main body, moving block, and guide rods. This dynamic structure allows the transducer to be positioned at different treatment depths without replacing the entire cartridge, thus reducing procedure time while maintaining structural simplicity
Solution Approach 2:
The cartridge is divided into functional modules: a fixed cartridge main body and a movable transducer assembly. The moving device segments the transducer positioning function from the overall cartridge structure, allowing independent adjustment of treatment depth while keeping the rest of the system simple
2Device complexity
If the transducer is fixed to a treatment part of one treatment depth, then the cartridge structure is simple, but multiple cartridges are needed for different treatment depths, increasing device complexity
Solution Approach 1:
The moving device enables a single cartridge to perform multiple treatment depths by allowing the transducer to be positioned at different locations along the ultrasound propagation direction. This multi-functional capability eliminates the need for multiple specialized cartridges, reducing overall device complexity while increasing adaptability
Solution Approach 2:
The dynamic positioning mechanism allows one cartridge structure to adapt to multiple treatment depths, providing versatility without requiring multiple fixed-depth cartridges. The moving block and guide rod system enables continuous adjustment of transducer position for different treatment requirements
3Device complexity
If the transducer moves in a straight line reciprocal motion at one treatment depth, then the mechanism is simple, but it cannot treat multiple depths without replacement
Solution Approach 1:
The moving device transforms the simple straight line reciprocal motion into a multi-depth capable mechanism by allowing the transducer to be repositioned along the ultrasound propagation direction. The moving main body and moving block system maintains mechanical simplicity while enabling depth adjustment capability
Solution Approach 2:
The mechanism adds the dimension of depth adjustment to the traditional straight line reciprocal motion. By incorporating the moving block that can be engaged with the transducer at different positions, the system gains the ability to operate at multiple depths while maintaining the simplicity of linear motion during treatment
