Solution Overview

Problem

Elevator operation mode management systems require multiple inputs of user identification information, increasing user time and effort when switching between ordinary and special operation modes.

Innovation Solution

A communication terminal system determines operation instructions based on read identification information and varying reading conditions, such as communication time and angle, allowing multiple operations with a single identification, reducing user effort and time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple inputs of user identification information are required to switch between operation modes, then operation mode switching becomes possible, but user time and effort increase

Engineering Contradiction:
Improveoperation mode switchingVSAvoiduser time and effort
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system changes the parameter of reading conditions (such as reading speed, number of reads, or timing) to differentiate between ordinary and special operation modes. Instead of requiring multiple separate identification inputs, the system interprets different reading patterns of the same identification information to trigger different modes, thereby reducing user effort while maintaining mode switching capability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The single identification information storage unit serves multiple functions by enabling both ordinary and special operation modes through different reading conditions. The same identification data is universally used for both mode types, eliminating the need for separate identification inputs and reducing user time and effort.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple inputs of user identification information are required, then operation mode switching becomes possible, but ease of operation decreases

Engineering Contradiction:
Improveoperation mode switchingVSAvoiduser effort
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system varies parameters such as reading speed, number of consecutive reads, or timing intervals to distinguish between ordinary and special modes. This allows the same identification information to trigger different operations without requiring users to input identification multiple times, significantly improving ease of operation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system automatically determines the operation mode based on the reading conditions of the identification information without requiring user intervention to select the mode. The reading device itself provides the service of mode determination, making the operation easier for the user.

Inventive Principle:
Principle #25Self-service

3Productivity

If identification information is read under different conditions, then multiple operations can be performed with single identification, but system complexity increases

Engineering Contradiction:
Improvemultiple operations with single identificationVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system uses parameter changes in reading conditions (speed, count, timing) to enable multiple operations from a single identification input. The control unit interprets these parameter variations to determine the appropriate operation mode, achieving high productivity without requiring complex additional hardware or identification mechanisms.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system dynamically adjusts operation modes based on real-time reading conditions of the identification information. The control unit flexibly determines whether to execute ordinary or special operations based on the detected reading parameters, enabling multiple operations while maintaining manageable system complexity through adaptive control logic.

Inventive Principle:
Principle #15Dynamics

AI summary

An object of the present invention is to provide a system for using a communication terminal, which along with being able to perform a plurality of operations using as single item of identification information, is able to reduce the time and effort imposed on a user. The system for using a communication terminal has a portable telephone user having a portable telephone 1, and a vehicle-mounted system is provided in a shared vehicle 2. In the portable telephone 1, an NFC 11 is provided, and the vehicle-mounted system in the shared vehicle 2, an R/W for NFC communication 21 is provided. When communication is performed for a first communication time between the R/W for NFC communication 21 and the NFC 11 by holding up the portable telephone 1 to the R/W for NFC communication 21 provided in the shared vehicle 2, door locking is performed. In addition, when communication is performed for a second communication time, a usage finishing process is performed.
