Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional space transformers are used to transmit high-frequency signals, then the transmission distance can be extended, but the signal quality degrades due to electromagnetic interference and attenuation
Solution Approach 1:
The patent introduces an RF signal-modifying structure as an intermediary component between the signal source and the device under test. This structure actively compensates for signal degradation by modifying the RF signals during transmission, thereby maintaining signal quality over extended transmission distances where conventional space transformers would fail
Solution Approach 2:
The patent modifies the electrical parameters of the space transformer by incorporating an RF signal-modifying structure that can dynamically adjust signal characteristics. This allows the transformer to adapt to different transmission conditions and maintain optimal signal integrity across varying transmission distances and frequency ranges
2Adaptability or versatility
If the pitch spacing between electrical contacts is reduced to adapt to different hardware, then the adaptability improves, but the manufacturing precision requirements increase
Solution Approach 1:
The patent creates a universal space transformer design that can accommodate multiple pitch spacings through the incorporation of an RF signal-modifying structure. This structure enables the same physical transformer to serve multiple functions by adapting to different pitch configurations without requiring separate precision-matched components for each hardware type
Solution Approach 2:
The patent segments the electrical contacts into multiple groups with different pitch spacings within the same space transformer body. This segmentation allows the transformer to interface with different hardware types while the RF signal-modifying structure compensates for the variations, reducing the stringency of manufacturing precision requirements for each individual contact group
3Reliability
If conventional probe systems are used for high-frequency signal transmission, then the system complexity remains low, but the signal transmission capability is insufficient
Solution Approach 1:
The patent merges the RF signal-modifying structure directly into the space transformer body, combining two previously separate functions (signal transformation and RF modification) into a single integrated component. This merging enhances signal transmission capability for high-frequency applications while minimizing the increase in overall system complexity by eliminating the need for separate external modification circuits
