Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If smaller and higher-performance transducers are used, then image quality and diagnostic capability are improved, but heat generation increases causing image distortion and reduced durability
Solution Approach 1:
The patent extracts the heat dissipation function from the traditional acoustic absorption layer by introducing a separate radiator component with high thermal conductivity material. This radiator is positioned between the controller and the external environment to specifically handle heat removal without interfering with the acoustic absorption function.
Solution Approach 2:
The patent adds a thermal management dimension to the existing acoustic module design by incorporating a radiator with extended surface area structures. This creates an additional heat dissipation pathway that operates independently from the acoustic wave propagation dimension.
2Temperature
If heat dissipation is enhanced through increased radiator surface area, then temperature control is improved, but device complexity increases
Solution Approach 1:
The patent merges the radiator with the existing acoustic absorption layer and controller packaging structure. The radiator is integrated into the housing or mounting structure of the controller, allowing heat dissipation functionality to be combined with structural and acoustic management functions in a unified design.
Solution Approach 2:
The radiator structure serves multiple functions: it acts as a heat dissipation component, provides structural support for the controller, and may contribute to the overall acoustic management of the module. This multi-functionality reduces the need for separate dedicated components.
