Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional password retrieval methods using SMS or email verification codes are used, then password retrieval functionality is provided, but user convenience deteriorates due to requiring external devices and manual code entry

Engineering Contradiction:

Improvepassword retrieval convenienceVSAvoiddependency on external devices

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The mobile terminal performs password verification independently using its own camera, sensors, and processing capabilities. The device captures images, extracts features, and completes verification without requiring external devices like computers or additional authentication tools, making the system self-sufficient and improving user convenience.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent extracts the verification code generation and verification processes from external communication channels (SMS, email) and relocates them entirely within the mobile terminal. By using on-device image recognition and feature matching, the system removes dependency on external messaging services and devices.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If ROM flashing at repair stations is used for password recovery, then password retrieval is possible, but user experience deteriorates due to complex operations and time consumption

Engineering Contradiction:

Improvepassword retrieval simplicityVSAvoidtime for password recovery

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The mobile terminal autonomously performs password verification using built-in cameras and sensors to capture images and extract features. This self-contained process eliminates the need to visit repair stations and perform complex ROM flashing operations, significantly reducing time loss and operational complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of ROM flashing (requiring physical connection to repair equipment) with an automated image recognition and feature matching system. The verification is performed through software-based image processing and algorithmic comparison, substituting complex hardware operations with streamlined computational methods.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If simple password verification is used, then user convenience is improved, but security deteriorates due to easy password cracking

Engineering Contradiction:

Improveverification simplicityVSAvoidpassword security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent transitions from traditional one-dimensional password verification (text-based) to multi-dimensional verification using image features, spatial relationships, and pattern recognition. By capturing images from multiple angles and extracting various feature types (edges, corners, textures), the system adds dimensional complexity that significantly enhances security while maintaining user-friendly operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The verification system combines multiple types of data (image pixels, feature vectors, spatial coordinates, timing information) into a composite verification signature. This composite approach integrates diverse information sources to create a robust security mechanism that is both secure and convenient for users.

Inventive Principle:

Principle #40Composite materials

AI summary

This application discloses a password verification method and a password setting method. The password verification method includes: in response to a detected operation of requesting for password verification, collecting at least one first image by using a camera of a mobile terminal; obtaining matching information when a result of matching between the at least one first image collected by the mobile terminal and at least one first preset image satisfies a first preset matching condition, where the matching information includes at least one of the following: location information of the mobile terminal, motion information of the mobile terminal, at least one second image collected by the camera of the mobile terminal, and network connection information of the mobile terminal; and performing matching between the obtained matching information and a second preset matching condition, where the password verification succeeds when the matching is successful.
