Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If capacitors are integrated into the circuit package and connected to the reference potential, then interference suppression is improved, but measurement precision deteriorates due to falsification of high-frequency measurement results
Solution Approach 1:
The patent segments the capacitor connections into two distinct groups: capacitors connected to the reference potential (ground) and capacitors connected to signal transmission connections. This segmentation allows the reference potential capacitors to provide interference suppression without affecting high-frequency signal measurements, as they are electrically isolated from the signal paths.
Solution Approach 2:
The patent introduces additional connection contacts (fourth and fifth connection contacts) as intermediaries between the capacitors and the external circuit. These intermediary connection points allow capacitors to be connected without directly interfacing with the integrated circuit's signal terminals, thereby preventing measurement falsification while maintaining interference suppression functionality.
2Device complexity
If capacitors are integrated into the circuit package, then device complexity is reduced, but measurement time increases during final testing
Solution Approach 1:
The patent makes the capacitor connections dynamic and configurable by providing separate fourth and fifth connection contacts that can be selectively connected or disconnected during different testing phases. During final testing, the connections can be configured to minimize measurement time, while still allowing capacitor integration for normal operation.
Solution Approach 2:
The patent enables parameter changes in the circuit configuration by allowing capacitors to be connected to different potentials (reference potential or signal transmission connections) depending on the operational mode. This flexibility allows optimization of measurement parameters during testing while maintaining interference suppression during normal operation.
3Object-affected harmful factors
If capacitors are connected to the reference potential, then interference suppression is improved, but device flexibility deteriorates due to limited connection configurations
Solution Approach 1:
The patent implements multi-functionality by allowing capacitors to serve multiple purposes: they can be connected to the reference potential for interference suppression, or connected to signal transmission connections for signal coupling or filtering. The additional fourth and fifth connection contacts provide universal interfaces that support various connection configurations depending on the application requirements.
Solution Approach 2:
The patent enables periodic reconfiguration of capacitor connections during different operational phases. Capacitors can be connected to the reference potential during normal operation for interference suppression, and reconfigured to signal transmission connections during testing or different operational modes, providing temporal flexibility in connection configurations.
