Construction Verification System Using Distributed Ledger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current construction processes lack accountability and reliability in verifying the materials and workers involved in a project, leading to potential substitutions, misinstallations, and compliance issues due to the lack of a systematic and immutable record of code compliance, which can result in quality and safety problems.
Innovation Solution
A digital system utilizing a kiosk at the construction site connected to a distributed ledger for real-time verification and recording of materials and workers, ensuring compliance with regulatory requirements through biometric identification, geofencing, and smart contracts for managing deliveries and inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional construction processes are used without systematic verification, then the process is simpler and faster, but reliability and accountability of material and worker verification deteriorate
Solution Approach 1:
The patent merges multiple verification functions (material tracking, worker identification, compliance verification, inspection recording) into a single integrated digital system with centralized database, replacing scattered manual processes with one unified platform that handles all verification aspects consistently
Solution Approach 2:
The patent introduces a digital verification system as an intermediary between construction activities and regulatory requirements, using automated tracking, biometric authentication, and digital record-keeping to mediate the verification process between workers, materials, and compliance standards
2Measurement precision
If manual inspection processes are used, then the system is easier to operate, but measurement precision and verification accuracy deteriorate
Solution Approach 1:
The patent replaces manual inspection processes with automated digital verification systems, using electronic databases, automated tracking, biometric authentication, and digital record-keeping to substitute human judgment and physical inspection with computerized verification mechanisms
Solution Approach 2:
The patent creates digital copies and records of all verification data (material specifications, worker credentials, inspection results, compliance certificates) stored in an immutable database, replacing physical documents and manual records with replicated digital information that can be verified without altering the original state
3Reliability
If comprehensive verification processes are implemented, then reliability and compliance improve, but loss of time in documentation and verification increases
Solution Approach 1:
The patent implements preliminary verification by pre-registering materials with unique identifiers, pre-credentialing workers with biometric data, and pre-establishing compliance criteria in the database before construction activities begin, allowing for rapid verification during execution without time-consuming manual checks
Solution Approach 2:
The patent maintains continuous verification through real-time tracking of materials and workers, automated logging of compliance data, and ongoing digital record-keeping throughout the construction process, eliminating interruptions for manual documentation and enabling seamless verification at any stage
4Manufacturing precision
If traditional material tracking methods are used, then the system is simpler, but manufacturing precision and material specification compliance deteriorate
Solution Approach 1:
The patent creates digital twins or virtual representations of physical materials by assigning unique digital identifiers and storing detailed specification data in the database, allowing verification of material compliance through digital copying and comparison without requiring complex physical inspection apparatus
Solution Approach 2:
The patent introduces a digital tracking system as an intermediary between material delivery and installation, using automated scanning, verification against pre-stored specifications, and digital record-keeping to mediate the material flow and ensure compliance without direct manual intervention at each step
Data Source
AI summary
This system is a decentralized computerized system for administration and management of a construction or manufacturing project having kiosk physically or virtually associated with the project and configured for receiving a building information model from a design computing device, transmitting the bill of material to a supply computer device, informing a third-party supplier to deliver the materials to the construction site, receiving a material delivery information, receiving an internal and external inspection information, receiving regulatory compliance information, receiving insurance information and receiving labor information, debiting a first account associated with the project and crediting a second account associated with the project, creating records or certificates representing various verifications of stages of the construction project and storing the records or certificates on a distributed ledger.
