Solution Overview

Problem

Printers face challenges in ensuring user privacy and preventing mixed printed materials when multiple users' printing tasks overlap, leading to inconvenience and increased risk of exposure of confidential information.

Innovation Solution

A printing control method and device that pauses or resumes printing tasks based on the state of mobile equipment, specifically when the equipment's identity verification information matches preset conditions, such as proximity or signal strength, ensuring secure and convenient printing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the printer directly executes printing tasks upon reception without verification, then the printing efficiency is improved, but the privacy security and risk of exposing confidential information deteriorates

Engineering Contradiction:
Improveprinting efficiencyVSAvoidprivacy security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by performing identity verification and distance measurement before executing the printing task. The printer first receives identity verification information from the mobile equipment, measures the distance, and only then proceeds with printing if verification succeeds and distance is within threshold. This pre-verification mechanism ensures privacy security without significantly impacting printing efficiency.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the printer sequentially executes printing tasks in chronological order, then the privacy security is improved, but the printing efficiency and user convenience deteriorates

Engineering Contradiction:
Improveprivacy securityVSAvoidprinting efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent performs preliminary identity verification and distance measurement before printing, allowing tasks to be executed as soon as verification succeeds rather than waiting for sequential processing. This enables parallel processing of multiple verification tasks while maintaining security, thereby improving overall printing efficiency compared to strict sequential execution.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces dynamic control by adjusting printing execution based on real-time verification results and distance measurements. Instead of fixed sequential processing, the system dynamically determines when and how to execute printing tasks based on current security conditions, optimizing both security and efficiency.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the printer adds identity verification and distance measurement, then the privacy security is improved, but the device complexity increases

Engineering Contradiction:
Improveprivacy securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses feedback mechanisms where the printer receives identity verification information from mobile equipment, measures distance, and uses this feedback to determine whether to proceed with printing. The system continuously monitors verification status and distance, adjusting execution decisions based on real-time feedback, which streamlines the security process while maintaining robust protection.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The mobile equipment performs self-verification by providing its own identity verification information to the printer. This self-service approach reduces the burden on the printer system, as the verification data comes from the equipment itself rather than requiring complex external verification infrastructure, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #25Self-service

4Reliability

If the user manually verifies printing tasks, then the privacy security is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveprivacy securityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system implements automatic verification where the mobile equipment automatically provides identity verification information and the printer automatically performs distance measurement and verification. This self-service mechanism eliminates the need for manual user verification, maintaining high privacy security while significantly improving ease of operation and user convenience.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical verification processes with automated electronic verification systems. Instead of users manually checking and approving printing tasks, the system uses automated identity verification protocols and distance measurement technology, substituting manual operations with electronic automation to improve both security and convenience.

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