Solution Overview

Problem

Existing anti-forgery technologies for official seals face issues such as time-consuming approval processes, large and power-hungry printers, aesthetically poor two-dimensional codes, inefficient printing methods, data security vulnerabilities, and lack of portability, which hinder efficient and secure authentication of documents.

Innovation Solution

An intelligent seal with cloud computing-based anti-forgery capability, utilizing a mobile app for level-by-level seal approval, image anti-forgery codes integrated into the seal design, rotational printing for efficiency, a centralized seal management platform for secure data storage, and a portable seal with a laser pointer module for accurate placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a two-dimensional code is printed in the middle of the seal for anti-forgery, then information extraction and tracing capability is improved, but aesthetics deteriorates and interference with document letters occurs

Engineering Contradiction:

Improveanti-forgery capabilityVSAvoidaesthetics

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The patent applies asymmetry by positioning the two-dimensional code at the outer edge of the seal rather than in the center, creating an asymmetric layout that avoids visual interference with the seal's central design elements and document letters, thereby maintaining both anti-forgery functionality and aesthetic appearance

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent moves the two-dimensional code from a central two-dimensional space to the outer edge, utilizing the peripheral dimension of the seal structure. This dimensional repositioning allows the code to coexist with the seal's aesthetic design without overlapping or interfering with central elements

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If a conventional inkjet printer with parallel printing is used, then printing capability is achieved, but printing speed deteriorates and energy consumption increases

Engineering Contradiction:

Improveprinting speedVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent employs periodic action by implementing an oscillating printing mechanism where the printhead moves back and forth in a rhythmic pattern, allowing continuous printing without the need for multiple trips, thereby improving printing speed and reducing energy consumption through efficient periodic motion

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent achieves continuity of useful action by maintaining constant printing motion through the oscillating mechanism, eliminating idle time between printing passes and ensuring the printhead is continuously depositing ink, which maximizes productivity and minimizes energy waste

Inventive Principle:

Principle #20Continuity of useful action

3Ease of operation

If seal information is stored in a built-in memory chip for authentication, then printing function activation is enabled, but data security deteriorates due to vulnerability to cracking

Engineering Contradiction:

Improveprinting activationVSAvoiddata security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent extracts the seal information storage function from the built-in memory chip and relocates it to a centralized cloud platform. This extraction removes the security vulnerability of local storage while maintaining the ease of operation for printing activation through cloud-based authentication

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a cloud platform as an intermediary between the seal device and the authentication system. This intermediary securely stores seal information and manages authentication, protecting data from direct access and cracking attempts while enabling seamless printing activation through cloud verification

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If a portable seal with rotational printing is used, then printing efficiency is improved, but device complexity increases due to additional modules

Engineering Contradiction:

Improveprinting efficiencyVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the rotational printing mechanism with the seal body structure, integrating the printing function directly into the seal's rotation rather than using a separate conventional printer. This merging reduces device complexity by eliminating the need for independent printing components while maintaining high printing efficiency

Inventive Principle:

Principle #5Merging (Combining)
