Elevator Controller Hall Guidance via Mobile Terminal

Solution Overview

Problem

Conventional elevator systems fail to guide users directly to the intended elevator hall when returning to their parked vehicle, leading to inconvenience as users often need to change elevators, causing inefficiency.

Innovation Solution

An elevator controller system that uses a mobile terminal to communicate with transmitters at elevator halls, determining the correct elevator to guide users back to the intended hall by matching identification and position information, ensuring users reach the correct elevator hall efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the elevator system only registers floor information without tracking elevator hall information, then the system simplicity is maintained, but the user convenience deteriorates because users may go to the wrong elevator hall and need to change elevators

Engineering Contradiction:

Improveuser convenienceVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary registration of both floor information and elevator hall information when the user first enters the building. This advance preparation ensures that when the user needs to return to their vehicle, the system already has the necessary information to guide them to the correct elevator hall, eliminating the need for real-time complex decision-making and elevator transfers

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to the user's mobile terminal about which elevator hall and specific elevator to use for returning to the registered floor. This feedback mechanism guides users directly to the correct elevator, preventing them from going to the wrong hall and avoiding the need to change elevators, thus improving convenience without requiring complex real-time system changes

Inventive Principle:

Principle #23Feedback

2Productivity

If the system registers destination floor without considering elevator hall, then the registration process is simple, but the time efficiency deteriorates as users may need to transfer between elevators

Engineering Contradiction:

Improvetime efficiencyVSAvoidinformation processing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary registration of both floor information and elevator hall information when the user first enters the building. This advance preparation ensures that when the user needs to return to their vehicle, the system already has the necessary information to guide them to the correct elevator hall, eliminating the need for real-time complex decision-making and elevator transfers

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system segments the return journey information into two distinct components: floor information and elevator hall information. By separating these elements during registration, the system can efficiently retrieve and communicate the specific elevator hall and elevator identifier to the user, enabling direct navigation without transfers and improving time efficiency

Inventive Principle:

Principle #1Segmentation

3Measurement precision

If the elevator controller only stores floor information associated with mobile terminal ID, then the storage structure remains simple, but the guidance accuracy deteriorates causing users to potentially reach the wrong elevator hall

AI summary

An elevator controller according to the present disclosure includes: a communication unit that receives, from a mobile terminal, signals each including information about elevator halls; and a determination unit that makes a determination for guiding a user on a basis of the information about the elevator halls received by the communication unit. The communication unit receives, from the mobile terminal, a first signal including floor registration elevator hall information, and after that, receives, from the mobile terminal, a second signal including registered floor return elevator hall information. On a basis of the first signal and the second signal, the determination unit determines whether or not an elevator at a registered floor return elevator hall is an elevator that goes to a floor registration elevator hall and, when the elevator is the elevator that goes to the floor registration elevator hall, notifies the mobile terminal the determination result.
