This system integrates multi-function IoT devices to collect and upload transportation data, enabling remote monitoring and ensuring data immutability and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional onsite inspection methods are used with paper-based forms, then inspection coverage can be comprehensive, but the inspection process is time-consuming and requires significant manpower
Solution Approach 1:
The patent uses digital copies (photos and videos) of construction modules to replace physical onsite inspection. Inspectors can review digital representations of modules remotely, eliminating the need to physically visit each module location. This copying approach maintains comprehensive inspection coverage while dramatically reducing inspection time and manpower requirements.
Solution Approach 2:
The patent replaces the mechanical system of physical onsite inspection with an automated digital system. Computation devices automatically capture, store, and manage inspection data, replacing manual paper-based forms and physical module examination. This substitution eliminates repetitive manual tasks while maintaining thorough inspection standards.
2Reliability
If multiple parties conduct sequential inspections and endorsements, then quality control can be thorough, but the process becomes fragmented and time-consuming
Solution Approach 1:
The patent merges multiple inspection and endorsement activities into a single integrated digital platform. All parties (contractors, inspectors, clients) access and interact with the same blockchain-based system, consolidating fragmented processes into one unified workflow. This merging maintains thorough quality control while eliminating the complexity of coordinating separate inspection systems.
Solution Approach 2:
The patent introduces a blockchain-based digital platform as an intermediary that mediates all inspection and endorsement activities. This intermediary automatically manages data sharing, verification, and endorsement workflows between multiple parties, replacing complex manual coordination with automated digital processes that maintain reliability while reducing procedural complexity.
3Reliability
If data is stored in traditional centralized systems, then data access is convenient, but data integrity and trust cannot be ensured against tampering
Solution Approach 1:
The patent segments the data storage system into a distributed blockchain network rather than a single centralized repository. Inspection data is divided into blocks distributed across multiple nodes, ensuring that no single point of failure or tampering can compromise overall data integrity. This segmentation maintains data accessibility while providing cryptographic guarantees against unauthorized modification.
Solution Approach 2:
The patent changes the fundamental parameters of data storage from centralized to distributed architecture. By implementing blockchain technology with cryptographic hashing and distributed consensus mechanisms, the system transforms how data is stored and protected. This parameter change ensures data integrity and trustworthiness while managing system complexity through established blockchain protocols.
4Loss of information
If logistics systems provide only map view and location information, then transportation tracking is simple, but secure information about module location and quality is not provided proactively
Solution Approach 1:
The patent implements automated feedback mechanisms where IoT sensors continuously monitor module conditions during transportation and automatically upload data to the blockchain system. This feedback loop provides proactive updates on location, temperature, humidity, and other quality parameters without requiring manual intervention. The system transforms passive tracking into active information provision, ensuring complete transportation information while managing complexity through automated sensor networks.
Data Source
AI summary
A method is provided for remotely assuring the quality and transportation of offsite construction components. The method involves placing a code on the module, where the code contains identity information about the module. Then the code is scanned to obtain the identity information and to upload it to a blockchain data storage facility. Access is allowed to the identity information in the blockchain data storage facility to relevant parties for the purpose of remotely inspecting the module to verify its quality. Based on this verification the module may be delivered to a transportation facility for transport. During transport location information about the module is collected and uploading it to blockchain data storage facility. Second access is allowed to the location information stored in the blockchain data storage facility to allow relevant parties to remotely understand the transportation situation of the module.
