Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If custom antennas are fabricated for specific applications, then measurement precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The antenna system is divided into a base antenna horn and interchangeable modules (expansion horns, parabolic antennas, lenses). This segmentation allows the core component to remain constant while only the application-specific module needs to be changed, reducing overall system complexity while maintaining measurement precision for different applications
Solution Approach 2:
The base antenna horn is designed as a universal component that can work with multiple different modules to serve various measurement applications. This multi-functionality eliminates the need for completely custom antennas for each application, reducing device complexity while preserving measurement precision through module-specific optimization
2Adaptability or versatility
If new antennas are fabricated when requirements change, then adaptability is improved, but loss of time and productivity decrease
Solution Approach 1:
The antenna system transitions from a static, custom-fabricated design to a dynamic, reconfigurable system where modules can be quickly exchanged. This allows the antenna to adapt to different measurement requirements without undergoing complete re fabrication, significantly improving productivity while maintaining adaptability
Solution Approach 2:
Instead of discarding the entire antenna when requirements change, only the specific module that no longer meets the requirements is replaced. The base antenna horn and other compatible modules are recovered and reused, reducing manufacturing time and improving productivity while maintaining the necessary adaptability
3Adaptability or versatility
If custom antennas are fabricated for each application, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the antenna into a reusable base component and interchangeable modules, the manufacturing cost is distributed across multiple uses of the base antenna horn. Only the relatively inexpensive modules need to be manufactured for each specific application, reducing overall manufacturing cost while maintaining adaptability
Solution Approach 2:
The universal base antenna horn can be manufactured once and used across multiple applications by simply changing modules. This eliminates the need to manufacture complete custom antennas for each application, significantly reducing manufacturing costs while preserving the adaptability to meet different measurement requirements
