Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual verification method is used, then verification process can be conducted with simple system, but verification efficiency is low and labor demand is high
Solution Approach 1:
The patent replaces the manual mechanical verification process with an automated digital system. The auxiliary verification system uses computers, databases, and software modules to automatically perform verification tasks that previously required manual human effort, thereby significantly improving verification efficiency while managing system complexity through automation.
Solution Approach 2:
The verification system enables self-service verification where the system automatically compares activity data against emission factors and calculation methods stored in the database. The auxiliary verification module autonomously identifies discrepancies and generates verification reports without requiring continuous manual intervention, allowing the system to serve itself in the verification process.
2Measurement precision
If manual sampling verification is used, then labor cost is reduced, but sampling rate is limited and accuracy is compromised
Solution Approach 1:
The patent implements a flexible sampling approach where the system can perform verification on a partial sample basis when resources are limited, or conduct excessive verification (100% sampling) when accuracy is prioritized. The auxiliary verification module allows users to configure sampling rates, enabling the system to perform more comprehensive verification than traditional methods when needed, thereby improving accuracy while managing productivity through automated processing.
3Reliability
If multiple on-site verification sessions are conducted, then verification thoroughness is improved, but time consumption and resource demand increase
Solution Approach 1:
The patent performs preliminary verification actions by automatically comparing activity data against emission factors and calculation methods before conducting on-site verification. The auxiliary verification module pre-identifies potential issues and prepares verification reports in advance, reducing the need for multiple repeated on-site sessions and thereby decreasing verification time while maintaining thoroughness.
Solution Approach 2:
The verification system implements feedback mechanisms where the auxiliary verification module continuously monitors verification progress, compares results against expected outcomes, and automatically adjusts verification strategies. This feedback loop enables the system to identify and address issues in fewer iterations, improving verification thoroughness while reducing the time required for multiple on-site sessions.
Data Source
AI summary
An auxiliary verification system of greenhouse gas inventory can receive raw data from a verified unit end and includes a verification database, a computing module, and a verification module. The computing module searches from the verification database for a GWP value and a GHG emission factor according to a part of data fields of an inventory item of the raw data, to calculate a second GHG emission value. The verification module checks whether or not a first verified GHG emission value of the inventory item is the same as the second GHG emission value. Through such automatic verification, it is possible to save labor and required time greatly, simplify the work process, and allow the verification of 100% of inventory items of the raw data.
