Blockchain Elevator Dispatching for Priority Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator dispatching systems do not account for the urgency and priority of calls from different floors, treating all calls equally.
Innovation Solution
A blockchain-based elevator dispatching system that uses a unique block chain address for each user, employing public and private keywords to identify users and their funds, and utilizing a consensus mechanism to verify and prioritize elevator calls based on user authentication and account balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all call requests are treated equally by the elevator dispatching system, then the system is simple to operate, but the urgency and priority of different floors are not taken into account
Solution Approach 1:
The patent segments the elevator dispatching system into multiple components: blockchain network for identity verification, consensus mechanism for priority determination, and elevator controller for execution. This segmentation allows the system to handle different call priorities while maintaining operational simplicity through automated processes.
Solution Approach 2:
The blockchain network acts as an intermediary between call requests and elevator dispatching. It provides a decentralized consensus mechanism that automatically determines call priority based on predefined rules, eliminating the need for complex centralized decision-making while ensuring adaptability to different urgency levels.
2Reliability
If blockchain verification is implemented for each call request, then user authentication and call prioritization are secured, but the system complexity increases
Solution Approach 1:
The blockchain network performs multiple functions simultaneously: user identity verification, call priority determination, and transaction recording. This multi-functionality reduces the need for separate verification systems, thereby maintaining reliability while limiting the increase in overall system complexity.
Solution Approach 2:
The system uses self-service mechanisms where the blockchain network automatically verifies user identities and determines call priorities without requiring manual intervention. This automation ensures reliable verification while simplifying the operational complexity through rule-based automated decision-making.
3Productivity
If dedicated elevator service is provided to passengers with sufficient balance, then operational efficiency is enhanced, but user anonymity is compromised
Solution Approach 1:
The patent extracts the identity verification function from the elevator dispatching process and places it in the blockchain network. The elevator controller only receives anonymized priority information without accessing users' real identities or balance details, thus enhancing productivity through priority-based dispatching while preserving user anonymity.
Solution Approach 2:
The blockchain network serves as an intermediary that verifies user balances and determines priorities without exposing users' personal information to the elevator controller. This intermediary role enables differentiated service based on balance status while maintaining user anonymity through cryptographic verification.

AI summary
A method for dispatching an elevator applied in a block chain system verifies a call for an elevator by a passenger. The method includes: controlling each node of the block chain system to verify the elevator call; broadcasting information to the block chain system as to verification granted when verification of the elevator call by a node is passed; saving consumption information of the elevator call when the quantity of verifications granted received by the node is greater than a first predetermined value; and controlling and dispatching an elevator to be at the service of the passenger as a dedicated elevator when the elevator call is successful. A device for dispatching elevators when called and a system are also provided.
