Solution Overview

Problem

Existing web-based work device systems lack efficient service support and access control for device-related data, requiring users to physically visit service centers for maintenance and setting changes.

Innovation Solution

A web-based work device system with a data provision device, device app, and service app that enables read-write access to operating settings via a long-range data exchange connection, allowing temporary write access only with user approval, and utilizing a service terminal for service-side operation, thereby enhancing access control and operational security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users physically visit service centers for maintenance and setting changes, then service support is provided, but user convenience deteriorates and time is lost

Engineering Contradiction:
Improveservice support accessibilityVSAvoidtime for physical visits
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical system of physical device transport with a digital communication system. Service personnel access device settings and perform maintenance remotely through electronic communication channels, eliminating the need for physical device movement and on-site service visits.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a communication server as an intermediary between the user device and service personnel. This server mediates the remote access process, enabling service support to be delivered without direct physical contact or device transport, thus saving user time while maintaining service quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If service personnel have direct access to device settings, then service efficiency is improved, but device security and user control deteriorate

Engineering Contradiction:
Improveservice support efficiencyVSAvoiddevice settings security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic access control where service personnel's access rights to device settings are not fixed but temporarily granted and revoked based on service needs. The system dynamically adjusts permission levels, allowing efficient service access when needed while automatically restoring security constraints when service is complete.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms where the user device monitors and controls service personnel access. The system provides feedback about access status to users and automatically manages permission revocation, ensuring that service efficiency is maintained while user control and security are preserved through continuous monitoring and adjustment.

Inventive Principle:
Principle #23Feedback
