Blockchain Material Weight Variation Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traceability technologies using blockchain or databases incorrectly treat natural material weight variations during manufacturing as unauthorized diversion or false increases, failing to accurately manage material quantities.
Innovation Solution
A management device that records transaction data on a blockchain, including a variation range registration unit to set and update an allowable weight variation range for materials, allowing for accurate tracking and detection of deviations from this range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain traceability technology is used to track material weight, then transparency and security of material tracking are improved, but natural weight variations during manufacturing are incorrectly treated as unauthorized diversion or false increases
Solution Approach 1:
The system pre-registers permissible weight variation ranges on the blockchain before material transactions occur. This preliminary action establishes expected variation boundaries that the tracking system can later reference to distinguish natural variations from unauthorized changes, resolving the contradiction by preparing the adaptability framework in advance while maintaining tracking reliability.
Solution Approach 2:
The invention introduces a new parameter (permissible weight variation range) to the blockchain tracking system. By registering and storing these variation ranges as formal parameters, the system gains the ability to accommodate natural weight fluctuations while maintaining the integrity and reliability of material tracking through the blockchain's immutable ledger.
2Reliability
If strict material weight monitoring is implemented on blockchain, then unauthorized diversion prevention is improved, but false accusations of material increase or diversion occur due to natural variations
Solution Approach 1:
By pre-registering permissible weight variation ranges on the blockchain before transactions, the system establishes a baseline for what constitutes normal variation. This preliminary action enables the system to accurately detect unauthorized diversion while avoiding false accusations, as any weight change outside the pre-registered range can be flagged as suspicious.
Solution Approach 2:
The pre-registered weight variation range acts as an intermediary parameter between the strict monitoring requirements and the natural variations in material weight. This intermediary allows the system to maintain high detection accuracy for unauthorized diversion while filtering out natural variations that would otherwise trigger false accusations.
3Loss of information
If blockchain records all material weight transactions, then traceability and transparency are improved, but the system cannot distinguish between natural weight variations and actual unauthorized changes
Solution Approach 1:
The invention enhances the blockchain tracking system by introducing and registering weight variation ranges as formal parameters. This parameter addition allows the system to maintain complete transaction records while gaining the precision to distinguish natural variations from genuine unauthorized changes, thereby improving measurement precision without losing information completeness.
Solution Approach 2:
By pre-registering the weight variation ranges before transactions occur, the system prepares the analytical framework needed to interpret recorded weight data. This preliminary action enables the system to maintain complete traceability information while accurately identifying genuine material changes by comparing recorded weights against the pre-established variation ranges.
