Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Field mechanics face inefficiencies and safety concerns due to the reliance on paper-based maintenance records, which can be lost or mismanaged, leading to difficulties in accessing and verifying maintenance history for equipment like elevators and conveyance systems.
Innovation Solution
A blockchain maintenance record system that uses a part identification tag, such as NFC or RFID, to create a maintenance data package including part identity, location, timestamp, and technician signature, which is uploaded to a blockchain network for secure and immutable storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paper-based maintenance records are used onboard or proximate the system, then mechanics can access maintenance records during field operations, but the records can be lost, mismanaged, or compromised, leading to reliability and security issues
Solution Approach 1:
The patent creates digital copies of maintenance records and stores them on a blockchain network, which is accessible via mobile computing devices. This replaces physical paper records with immutable digital equivalents that can be accessed remotely, solving both the reliability issue through cryptographic security and the accessibility issue through mobile device connectivity.
Solution Approach 2:
The patent replaces the mechanical paper-based record-keeping system with an electronic blockchain-based system. Mobile computing devices with applications replace physical record books, and blockchain technology replaces manual record management, providing both improved reliability through decentralization and maintained accessibility through mobile interfaces.
2Device complexity
If centralized maintenance record systems are used, then record management is simplified, but single points of failure and security vulnerabilities increase
Solution Approach 1:
The patent segments the maintenance record storage system into distributed nodes across a blockchain network rather than a single centralized repository. Each node holds a copy of the ledger, eliminating single points of failure while maintaining manageable complexity through standardized protocols and mobile device interfaces.
3Productivity
If manual paper record keeping is used, then implementation is simple and low-cost, but time to record and retrieve maintenance information increases, reducing productivity
Solution Approach 1:
The patent enables mechanics to self-record maintenance data directly into the system using mobile devices during field operations. The application automatically captures relevant information and uploads it to the blockchain, eliminating the need for separate manual recording steps and reducing the time to both record and retrieve maintenance information.
