Blockchain Measurement Device Leasing State Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional device leasing processes are plagued by issues such as lessees damaging devices due to abnormal use, lessors concealing device problems, and intermediary service providers improperly invoicing, leading to disputes over compensation and faithful execution of leasing agreements.
Innovation Solution
A blockchain-based method and apparatus for leasing measurement devices, which includes a lease platform node, lessor client, and lessee client, where existing state information is stored on the blockchain to prevent tampering and ensure authenticity, allowing for device state detection and secure lease contract creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional device leasing process is used, then device leasing can be performed, but device state information can be tampered with and fraudulent activities can occur
Solution Approach 1:
The patent introduces a blockchain as an intermediary system that mediates between lessors and lessees. The blockchain stores device state information in a distributed, tamper-proof manner, acting as a neutral third party that neither lessor nor lessee can unilaterally manipulate. This intermediary mechanism ensures authenticity while maintaining relative process simplicity.
Solution Approach 2:
The patent creates a digital copy of device state information on the blockchain, which serves as an immutable record. Instead of relying on physical inspection or trust between parties, the system uses a digital replica stored on the blockchain that cannot be altered, ensuring authenticity without requiring complex verification procedures.
2Reliability
If lessor stores device state information privately, then information security is maintained, but lessee cannot verify device condition before leasing
Solution Approach 1:
The patent segments the information storage function by distributing device state information across multiple blockchain nodes rather than keeping it centralized with the lessor. This segmentation allows any participant in the network to access and verify the information, ensuring transparency while maintaining security through cryptographic hashing and distributed storage.
Solution Approach 2:
The system implements a feedback mechanism where device state information is continuously updated and recorded on the blockchain. The lessee receives feedback about the actual device condition through the blockchain, allowing verification before leasing. This feedback loop ensures information transparency without compromising security, as the blockchain verifies the authenticity of the feedback information.
3Ease of operation
If intermediary service provider is used, then leasing coordination is improved, but improper invoicing and fraudulent activities can occur
Solution Approach 1:
The patent replaces the traditional intermediary service provider with a blockchain-based system that acts as a neutral mediator. The blockchain automatically records all transactions and device state changes, eliminating the need for human intermediaries who could improperly invoice. The system maintains ease of operation through automated smart contracts while ensuring invoice accuracy through immutable blockchain records.

AI summary
A method for operating a measurement device using a blockchain. A blockchain system comprises a lease platform node or lease platform node device, a lessor client, and a lessee client. Existing state information about the measurement device is stored in the blockchain. The method can include receiving a lease order for the measurement device that is sent by a lessee client, sending a lease notification based on the measurement device to the lessor client to notify the lessor to send the measurement device to the lessee, receiving, after the lessee receives the measurement device sent by the lessor, a device state detection request sent by the lessee client or the measurement device, wherein the device state detection request comprises first current state information about the measurement device, and detecting whether the first current state information matches the existing state information, and if yes, creating a lease contract for the measurement device.
