Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the signal processing system is redesigned to compensate for additional signal distortions from new external components, then the compensation effectiveness is improved, but the device complexity and cost increase
Solution Approach 1:
The hardware filter units are made reconfigurable through dynamic adjustment of filter coefficients, allowing the system to adapt to different external components without physical redesign. The control module dynamically updates filter parameters based on detected frequency response deviations, enabling the same hardware to serve multiple compensation purposes.
Solution Approach 2:
The system changes the parameters of existing hardware filter units (filter coefficients, cutoff frequencies, Q-factors) to compensate for different external components. By modifying these parameters rather than the hardware structure itself, the system achieves adaptability without increasing device complexity or requiring costly redesigns.
2Adaptability or versatility
If software filters are used to compensate for signal distortions, then the adaptability is improved, but the processing speed decreases
Solution Approach 1:
Existing hardware filter units are made multi-functional by enabling them to compensate for multiple types of external components through reconfiguration. The same hardware filters serve both their original purpose and the additional compensation function, eliminating the need for separate software filters and maintaining high processing speed while achieving broad adaptability.
Solution Approach 2:
The patent replaces software-based filtering (slower, flexible) with reconfigurable hardware filtering (faster, adaptable). By substituting the software filter mechanism with a reconfigurable hardware filter mechanism, the system achieves both the adaptability of software and the speed of hardware.
3Manufacturing precision
If additional hardware filter units are added to compensate for new distortions, then the compensation precision is improved, but the device complexity and cost increase
Solution Approach 1:
The existing hardware filter units are made self-reconfigurable, allowing them to adapt to different compensation needs without requiring additional filter units. The filters serve themselves by dynamically adjusting their own parameters under control of the control module, achieving high compensation precision with the same hardware resources.
Solution Approach 2:
The static hardware filter units are transformed into dynamic, reconfigurable filters that can change their characteristics in real-time. This dynamic capability allows a single filter unit to provide multiple levels of compensation precision for different external components, eliminating the need to add more filters to improve accuracy.
