Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional cable coupling configuration with shield covering layer, ring-shaped gasket, and cable clamp is used, then electromagnetic shielding is achieved, but the device complexity increases and manufacturing efficiency decreases
Solution Approach 1:
The patent combines the cable clamp and ring-shaped gasket into a single integrated cable clamp structure. The cable clamp directly contacts the shield covering layer and the housing simultaneously, eliminating the need for separate gasket components. This merging reduces the number of parts while maintaining electromagnetic shielding effectiveness through direct electrical contact between the cable clamp, shield, and housing.
Solution Approach 2:
The cable clamp serves multiple functions: it mechanically secures the cable to the housing, provides electrical connection between the shield covering layer and housing, and acts as an electromagnetic shield itself. This multi-functionality eliminates the need for separate components dedicated to each function, simplifying the overall cable coupling configuration while maintaining shielding effectiveness.
2Object-affected harmful factors
If a traditional cable coupling configuration with multiple components is used, then electromagnetic shielding is achieved, but the manufacturing time increases
Solution Approach 1:
By integrating the cable clamp and ring-shaped gasket into a single component, the manufacturing process is simplified from multiple assembly steps to a single installation operation. The cable clamp can be directly attached to the housing with the cable in place, eliminating the need for separate gasket installation and reducing manufacturing time while maintaining electromagnetic shielding.
3Volume of moving object
If the ultrasonic device is downsized with a simple configuration, then the device size is reduced, but it becomes difficult to form connector terminals and couple the housing
Solution Approach 1:
The cable clamp is designed to perform multiple functions in a compact form: it secures the cable, provides electrical connection, and attaches to the housing simultaneously. This integrated design allows the ultrasonic device to maintain small dimensions while still enabling effective cable coupling and connector terminal formation without requiring additional space for separate components.
