Solution Overview
Problem
Current systems lack efficient and real-time methods for reporting and monitoring issues at specific locations, such as restaurants or hotels, leading to delayed responses and inaccurate tracking of maintenance, cleanliness, and safety records.
Innovation Solution
The implementation of machine-readable tags that allow mobile devices to scan and access digital records, enabling users to report issues and update status in real-time, with features like NFC and QR codes linking to blockchain-verified information and alerting administrators or responders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional manual reporting methods are used, then system complexity is low, but response time is delayed and information accuracy deteriorates
Solution Approach 1:
The patent replaces manual mechanical reporting systems with automated digital systems using mobile devices, NFC tags, and blockchain technology. This substitution eliminates paper-based workflows and manual data entry, enabling real-time issue reporting and tracking while maintaining information integrity through cryptographic verification.
Solution Approach 2:
The patent introduces digital intermediaries including NFC tags placed at locations, mobile device applications, and blockchain smart contracts as mediators between users and the reporting system. These intermediaries automate the collection, verification, and transmission of issue reports, eliminating direct human-to-human communication delays while preserving system simplicity through standardized interfaces.
2Measurement precision
If digital record systems are implemented, then information accuracy improves, but system complexity increases
Solution Approach 1:
The patent creates digital copies of physical issues through mobile device captures (photos, descriptions, sensor data) and stores them on the blockchain. These cryptographic copies preserve the exact state of reported issues immutably, ensuring information accuracy without requiring complex centralized verification systems, as the blockchain's distributed consensus provides inherent validation.
Solution Approach 2:
The patent transforms physical issue parameters (location, time, condition) into digital data parameters that can be verified and tracked on the blockchain. By changing the state of information from analog to digital with cryptographic hashing, the system achieves high measurement precision while managing complexity through standardized data structures and automated verification protocols.
3Loss of information
If real-time updating is enabled, then information currency improves, but data integrity risks increase
Solution Approach 1:
The patent implements feedback mechanisms where each update to a digital record generates a new blockchain transaction that references previous states. This creates an immutable audit trail that provides real-time information currency while ensuring data integrity, as any attempted modification would be visible on the blockchain and rejected by the consensus mechanism.
Solution Approach 2:
The patent performs preliminary cryptographic hashing and verification of data before it is committed to the blockchain. By pre-validating information integrity through digital signatures and hash verification, the system enables real-time updating while preventing unauthorized or corrupt data from entering the immutable ledger, thus maintaining both information currency and reliability.
Data Source
AI summary
A system and a method are disclosed that enable a mobile device to use an encoded tag to initiate and maintain communications with at least one remote server. The encoded tag is positioned to identify a point of interest, and in response to using the mobile device to scan the encoded tag, communications regarding the point of interest may be initiated. A single encoded tag may be used to obtain and update recorded information about the point of interest, to notify others about an issue related to the point of interest, to log into the system, and to wait to be alerted about an issue related to the point of interest. If an issue relating to a point of interest has been reported, the system and method may monitor the reported issue to ensure that an action has been taken to address the reported issue.
