Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing apparatuses are unable to measure operation margin while operating, which is crucial for assessing the resilience of communication systems against noise interference.
Innovation Solution
A computing apparatus is designed with a differential transmission line, a noise application unit, a noise control unit, and a margin measurement unit. This setup allows for the application of noise to the differential transmission line and the measurement of communication errors, enabling the calculation of operation margin during normal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If noise is applied to the differential transmission line to measure operation margin, then measurement capability is improved, but communication error frequency increases
Solution Approach 1:
The patent implements dynamic margin measurement by continuously or periodically applying noise during operation and measuring communication errors in real-time. The noise application unit dynamically adjusts noise levels while the communication system operates, allowing operation margin to be measured without stopping normal communication functions. This resolves the contradiction by making the measurement process adaptive and integrated into ongoing operations rather than a static pre-deployment test.
Solution Approach 2:
The patent employs feedback mechanisms where the margin measurement unit continuously monitors communication error frequency and feeds this information back to the noise control unit. The system uses this feedback to adjust noise application levels and interpret measurement results, enabling intelligent differentiation between normal operational variations and actual margin degradation. This feedback loop resolves the contradiction by transforming increased error frequency into useful measurement data rather than单纯的 failures.
2Reliability
If real-time noise application is implemented for margin measurement, then operational awareness is improved, but system complexity increases
Solution Approach 1:
The patent integrates margin measurement functionality into existing communication infrastructure components. The noise application unit, noise control unit, and margin measurement unit are designed to work with standard differential transmission lines and communication protocols without requiring separate dedicated measurement infrastructure. This multi-functionality approach resolves the contradiction by enabling real-time operational awareness using adapted existing components rather than completely new complex systems.
Solution Approach 2:
The communication system performs self-diagnosis by using its own operational data to measure operation margin. The system applies noise to itself and measures its own communication error frequency, eliminating the need for external testing equipment or separate measurement systems. This self-service capability resolves the contradiction by providing operational awareness through the system's inherent components rather than adding external complexity.
3Measurement precision
If noise application unit is added to measure operation margin, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges the noise application unit, noise control unit, and margin measurement unit into an integrated measurement system that works cooperatively with the existing differential transmission line. Rather than adding completely separate independent systems, these components are combined to form a unified margin measurement functionality that shares resources and control mechanisms with the operational communication system. This merging approach resolves the contradiction by achieving measurement accuracy through integrated components rather than numerous separate devices.
