Solution Overview

Problem

Existing elevator systems struggle to efficiently manage the usage fees for multiple moving bodies, such as autonomous robots, which can occupy elevator transport capacity, leading to potential hindrance of human passenger usage without accurately reflecting the demand of the moving bodies.

Innovation Solution

An elevator charging system that includes communication and assignment units to receive and prioritize usage requests from moving bodies based on desired prices, ensuring that usage fees accurately reflect demand and optimize transport capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If usage fees are charged for elevator usage by moving bodies, then transport capacity can be adjusted to prevent hindrance of human passenger usage, but the usage fees may fail to reflect the demand of the moving bodies

Engineering Contradiction:
Improveelevator transport capacity utilizationVSAvoiddemand information of moving bodies
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system implements a feedback mechanism where moving bodies submit desired price information along with their usage requests. The management server processes this feedback and determines actual usage fees based on the collected demand information, ensuring that pricing reflects true demand while optimizing elevator capacity utilization

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system changes the parameter of usage fee from a fixed value to a dynamic value that varies based on demand. By collecting desired price information from multiple moving bodies and processing it through the management server, the usage fee becomes a variable parameter that reflects real-time demand conditions

Inventive Principle:
Principle #35Parameter changes

2Productivity

If multiple moving bodies use the elevator simultaneously, then transport capacity is occupied, but human passenger usage may be hindered

Engineering Contradiction:
Improveelevator usage by moving bodiesVSAvoidhuman passenger usage
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system dynamically adjusts elevator allocation and usage fees based on real-time demand from moving bodies. The management server processes usage requests and desired prices dynamically, allowing the system to adapt to changing conditions and optimize the balance between moving body usage and human passenger availability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the usage fee parameter to reflect demand levels, using this information to dynamically control elevator allocation. By varying the usage fee based on demand, the system optimizes capacity utilization while ensuring human passenger needs are met

Inventive Principle:
Principle #35Parameter changes

AI summary

Provided are an elevator charging system, a management server, a moving body, a moving body server, a charging method, and a storage medium storing program that make it possible to charge usage fees reflecting the demand of moving bodies. In a charging system (1), cars (5) transport moving bodies (11) between a plurality of floors. A communication unit (7a) receives usage requests each corresponding to one of the moving bodies (11). Each of the requests includes information about a call requesting assignment to one of the cars (5), and information about a desired price for a usage fee. An assignment unit (8) assigns each call to one of the cars (5) while prioritizing calls in requests having higher priority, based on information including the desired prices. A storage unit (9a) stores therein the fees charged for the requests of which the calls have been assigned.
