Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the ultrasonic driver circuit and ultrasonic oscillation element are disposed close to each other, then the device complexity is reduced, but electromagnetic wave interference increases
Solution Approach 1:
A shielding member is introduced as an intermediary component between the ultrasonic driver circuit and ultrasonic oscillation element. This shielding member blocks electromagnetic waves generated by the driver circuit from interfering with the oscillation element, allowing the components to be disposed close to each other without suffering from electromagnetic interference.
2Object-generated harmful factors
If a shielding member is added to block electromagnetic waves, then electromagnetic wave interference is reduced, but the device complexity increases
Solution Approach 1:
The shielding member is merged with the existing probe structure by forming it as an integrated component within the probe housing. This integration approach reduces the overall device complexity by eliminating the need for separate shielding components while still providing effective electromagnetic wave blocking.
3Object-generated harmful factors
If the head material is changed to non-conductive material, then electromagnetic wave shielding is improved, but the ultrasonic wave transmission efficiency decreases
Solution Approach 1:
Different parts of the probe are assigned different material properties: the head portion is made of non-conductive material for electromagnetic shielding, while the shielding member is strategically positioned to provide additional electromagnetic protection without interfering with the ultrasonic transmission path. This local differentiation allows each component to optimize its specific function.
4Reliability
If the probe structure is sealed to prevent moisture ingress, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The probe structure is segmented into distinct components (housing, shielding member, internal components) that can be manufactured separately and then assembled. This segmentation allows each component to be manufactured using standard processes, and the sealing function is achieved through the assembly interface between components, reducing overall manufacturing complexity.
