Solution Overview

Problem

Existing user management systems for electrical devices lack effective authority control, allowing unauthorized users to access and operate devices, particularly children who may not understand the control specifications, leading to potential misuse.

Innovation Solution

A user management system where application software is actuated by an operation terminal, with a first-registered user determining and granting operation authority to others, including approval, cancellation, and changing of user authorities, ensuring only appropriate users can operate and manage the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user registration is restricted to administrators only, then device security is improved, but user accessibility and ease of operation deteriorate

Engineering Contradiction:
Improvedevice securityVSAvoiduser accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent segments user authority into multiple levels: administrators who can perform user registration and authority management, and general users who can operate the device. This segmentation allows the system to maintain security through administrator control while improving accessibility by enabling broader user registration under administrator-approved authority.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If operation authority is given to multiple users, then ease of operation is improved, but authority control and device security deteriorate

Engineering Contradiction:
Improveuser accessibilityVSAvoidauthority control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements dynamic authority management where the first-registered user can flexibly grant, modify, or revoke operation authority for other users based on changing needs. This dynamic approach allows the system to adapt authority distribution over time, maintaining security while enabling convenient multi-user operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides feedback mechanisms where administrators and users can monitor and manage authority assignments. The first-registered user receives feedback about who has been granted authority and can adjust permissions accordingly, ensuring continuous control over device access while maintaining ease of operation for authorized users.

Inventive Principle:
Principle #23Feedback

AI summary

The present invention provides a user management system of an electrical device 10 wherein application software is actuated by an operation terminal 8, a user acquires operation authority of the electrical device 10, and a user who is first user-registered determines whether the operation authority is acquired by other user. According to this, it is possible to provide a management system capable of denying approval request of acquisition of the authority of a user such as a child who does not understand control specification of the electrical device 10, and capable of giving the operation authority of the electrical device 10 to an appropriate user.
