Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional modular measuring devices are assembled with separate shielding components, then shielding effectiveness is achieved, but assembly complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines the shielding function with the housing structure by integrating a conductive film into the plastic housing wall during manufacturing. This merging of functions eliminates separate shielding components and simplifies assembly, while maintaining effective shielding against signal interference through the integrated conductive layer.
Solution Approach 2:
The shielding structure is prepared in advance during housing manufacturing, with the conductive film already embedded in the plastic housing wall. This preliminary integration of the shielding function into the housing structure eliminates the need for separate assembly steps, reducing manufacturing complexity while ensuring shielding effectiveness.
2Ease of manufacture
If integral shielding is implemented through manufacturing integration, then assembly is simplified, but manufacturing precision requirements increase
Solution Approach 1:
The patent uses a thin conductive film integrated into the plastic housing wall during manufacturing. This thin film approach allows for effective shielding with minimal impact on housing structure, while the flexibility of the film enables integration during standard manufacturing processes without requiring extreme precision.
3Object-affected harmful factors
If separate shielding components are used, then shielding effectiveness is ensured, but production time and cost increase
Solution Approach 1:
By merging the shielding function into the housing structure through integrated conductive film, the patent eliminates separate shielding components and assembly steps. This integration maintains electromagnetic interference protection while significantly improving manufacturing efficiency by reducing assembly operations and production time.
Solution Approach 2:
The shielding function is preliminarily integrated into the housing during manufacturing, eliminating the need for separate shielding component assembly. This preliminary integration streamlines production, reduces assembly time, and improves overall manufacturing efficiency while maintaining shielding effectiveness.
