Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional rental systems are used, then existing infrastructure can be maintained, but transaction processing speed and security are insufficient
Solution Approach 1:
The patent replaces traditional mechanical rental systems with an unmanned automated system using blockchain technology. Smart contracts automatically execute rental agreements without human intervention, while IoT devices enable remote monitoring and control of rented equipment. This substitution achieves both high-speed automated transaction processing and enhanced security through cryptographic verification, resolving the contradiction between processing speed and security.
Solution Approach 2:
The patent introduces blockchain as an intermediary layer between users and rental services. The blockchain network acts as a trusted mediator that automatically verifies and executes rental transactions through smart contracts, eliminating the need for traditional payment processing and manual approval systems. This intermediary enables rapid, secure transactions while maintaining reliability through decentralized consensus mechanisms.
2Extent of automation
If manual control methods are used, then system complexity is low, but real-time control capability is lacking
Solution Approach 1:
The patent implements a multi-functional integrated system where a single platform combines rental management, real-time monitoring, automated control, and payment processing. The system can simultaneously handle multiple rental transactions, monitor various parameters of rented equipment, and execute control commands across different devices. This universal approach enables real-time automation while managing complexity through standardized protocols and interfaces.
Solution Approach 2:
The patent enables rented equipment to self-report status information and automatically respond to control commands through embedded IoT sensors and actuators. The system performs self-diagnosis, self-monitoring, and self-adjustment without requiring complex external control infrastructure. This self-service capability achieves real-time automation while reducing overall system complexity by distributing intelligence to the devices themselves.
3Productivity
If paper-based transactions are used, then system implementation is simple, but transaction efficiency is low
Solution Approach 1:
The patent replaces paper-based transaction systems with digital blockchain-based smart contracts. Rental agreements are automatically generated, signed, and executed as cryptographic contracts on the blockchain network. This substitution eliminates manual paperwork while providing automated verification, tracking, and enforcement of rental terms. The system achieves high transaction efficiency through programmable smart contracts that automatically execute upon meeting predefined conditions, with complexity managed through standardized contract templates and automated deployment.
