Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If authentication is implemented for multiple stylus pens, then security is improved, but device complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoidauthentication management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The authentication system is segmented by assigning unique identification information to each stylus pen and creating separate authentication records in the database. Each stylus pen undergoes independent authentication with its own authentication information (fingerprint, iris, or voice), allowing the system to manage multiple stylus pens through divided, independent authentication modules rather than a monolithic system.

Inventive Principle:

Principle #1Segmentation

2Reliability

If authentication information is stored in the database, then security is improved, but loss of time occurs during authentication process

Engineering Contradiction:

ImprovesecurityVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-storing authentication information (fingerprint, iris, or voice data) and identification information in the database before actual stylus pen usage. When a stylus pen is connected, the system quickly retrieves and compares the stylus pen's identification information against the pre-stored authentication information, eliminating the need for time-consuming authentication data collection during the actual authentication moment.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple stylus pens are supported, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvemultiple stylus pen supportVSAvoidinput management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electronic device implements a universal authentication framework that works across multiple stylus pens with different identification information. The system uses a unified database structure and authentication process that can handle any number of stylus pens, making the device adaptable to various stylus pens without requiring device-specific modifications for each stylus pen model.

Inventive Principle:

Principle #6Universality (Multi-functionality)
