Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is implemented for stylus pen input, then security is improved, but operation complexity increases
Solution Approach 1:
The system performs authentication in advance before allowing stylus pen input operations. The authentication screen is displayed and verified before the actual content input or modification can occur, ensuring security is established prior to operation.
Solution Approach 2:
An authentication screen acts as an intermediary layer between the stylus pen input and the actual content processing. This intermediary requires verification of authentication information before allowing the stylus pen to interact with protected content, thus enhancing security without directly complicating the core input operation.
2Adaptability or versatility
If multiple stylus pens are supported with differentiated functionalities, then versatility is improved, but device complexity increases
Solution Approach 1:
The system segments stylus pen management by assigning unique identification information to each stylus pen. Each pen can be associated with different authentication levels or user profiles, allowing differentiated functionalities while maintaining individualized control and simplifying the overall management structure.
Solution Approach 2:
The electronic device is designed to universally support multiple stylus pens with the same basic interface and communication protocol. The authentication mechanism and identification system provide a universal framework that accommodates various pen types and user scenarios without requiring separate complex systems for each pen.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances security and efficiency in processing stylus pen inputs by authenticating and managing multiple pens, allowing for differentiated content provision based on authentication.
Implementation Method 1
The electronic device may detect magnetic fields produced from the stylus pen using electro magnetic resonance (hereinafter, referred to as EMR)
Implementation Method 2
An electronic device may identify the position of a stylus pen based on an electromotive force generated by a magnetic field per channel
Implementation Method 3
The stylus pen may be connected with the electronic device via short-range communication (e.g., Bluetooth low energy (BLE))
