Solution Overview

Problem

Existing terminal devices require users to manually manage passwords and account information for electronic instruments, increasing the burden as the number of instruments increases, and do not facilitate automatic acquisition of account information from instruments operating in a second mode.

Innovation Solution

A terminal device with a communication unit, storage unit, and processing unit that allows communication with electronic instruments in both a normal and second mode, enabling automatic acquisition and storage of account information for processing in the normal mode, reducing the need for user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually manage passwords and account information for electronic instruments, then security and control are maintained, but the burden on users increases and convenience decreases

Engineering Contradiction:

ImproveUser burden in managing account informationVSAvoidAutomatic acquisition of account information

Core Design Contradiction:

Ease of operationVSExtent of automation

Solution Approach 1:

The terminal device automatically acquires account information from the electronic instrument without requiring user manual input. The system performs self-service by autonomously establishing communication in the second mode, retrieving account credentials, and storing them for future use, thereby eliminating the need for users to manually manage passwords across multiple devices.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by establishing communication with the electronic instrument in the second mode before actual processing is needed. Account information is acquired and stored in advance, so that when the terminal device needs to process tasks in the first mode, the authentication credentials are already available, eliminating the need for users to input passwords at the time of use.

Inventive Principle:

Principle #10Preliminary action

2Extent of automation

If the terminal device communicates with electronic instruments in multiple modes, then automatic account information acquisition is enabled, but device complexity increases

Engineering Contradiction:

ImproveAutomatic account information acquisitionVSAvoidCommunication mode management

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The communication process is segmented into distinct modes: the second mode is specifically dedicated to account information acquisition, while the first mode handles normal processing tasks. This segmentation allows the system to manage complexity by clearly defining the purpose and characteristics of each communication mode, making it easier to implement automated account management without overwhelming the system architecture.

Inventive Principle:

AI summary

Provided is a terminal device that includes a communicator that communicates with an electronic instrument operable in a first mode that is a normal mode and in a second mode, a storage, and a processor. The processor acquires, from the electronic instrument which is in the second mode, predetermined account information for performing predetermined processing with the electronic instrument in the first mode. The storage stores the acquired predetermined account information. The predetermined account information is acquired by a first application program. The processor installs a second application program and performs the predetermined processing according to the second application program with the electronic instrument in the first mode, where the first application program is different from the second application program.
