Digital Twin Event Filtering for IoT Blockchain Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid occurrence of IoT sensor events poses a challenge in efficiently managing data writes to databases or blockchain structures, as many events may be minor and unnecessary, leading to excessive data storage and processing burdens.
Innovation Solution
A digital twin event identification program that utilizes IoT sensor readings to determine the criticality of events, allowing only major events to be written to a blockchain structure, while minor events are stored in traditional databases or ignored, based on predefined owner preferences and criticality scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all IoT sensor events are written to blockchain structure, then data completeness is improved, but system load and storage costs increase excessively
Solution Approach 1:
The patent extracts and filters out only the critical events from the complete set of IoT sensor events. The event filtering module identifies and selects only those events that meet predefined criticality thresholds, writing them to the blockchain structure, while non-critical events are discarded or stored separately, thus resolving the contradiction between data completeness and system efficiency.
Solution Approach 2:
The patent applies different quality standards to different events based on their criticality. Critical events receive full blockchain storage with maximum data integrity, while non-critical events are handled with simpler storage or filtering. This local differentiation of data quality requirements resolves the contradiction by allocating resources proportionally to event importance.
2Productivity
If criticality filtering is implemented to reduce blockchain writes, then system efficiency is improved, but data loss of minor events occurs
Solution Approach 1:
The patent segments the event data into two distinct categories: critical events that are written to the blockchain structure and non-critical events that are filtered out or stored separately. This segmentation allows the system to maintain high efficiency by limiting blockchain writes to only necessary data, while the decision about non-critical event handling can be configured based on specific requirements.
Solution Approach 2:
The patent changes the parameter of event selection from including all events to including only events above a certain criticality threshold. The event filtering module uses configurable parameters to determine which events are critical, allowing flexible adjustment of the filtering criteria to balance between system efficiency and data completeness based on specific application needs.
3Reliability
If blockchain structure is used for all events, then data security and immutability are improved, but storage costs and processing time increase
Solution Approach 1:
The patent extracts only the critical events that require blockchain's security and immutability properties, writing them to the blockchain structure. Non-critical events are excluded from blockchain processing entirely, thus eliminating the unnecessary processing time and storage costs associated with blockchain while maintaining security for events that truly require it.
Solution Approach 2:
The patent applies blockchain technology partially rather than excessively to all events. By using blockchain only for critical events where its security and immutability properties are necessary, the system avoids the excessive processing time and storage costs that would result from applying blockchain to all events, while still maintaining adequate security for important data.
