Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cable connection is used for screen casting, then transmission stability is improved, but device complexity and cost increase

Engineering Contradiction:
Improvetransmission stabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical cable connection system with a wireless communication system. The screen casting apparatus establishes wireless communication links (first communication link to source device, second communication link to display device) to transmit screen casting information, eliminating the need for physical cable connections while maintaining transmission functionality.

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

Solution Approach 2:

The screen casting apparatus acts as an intermediary device between the source device and display device. It receives screen casting information from the source device via the first communication link, processes the information, and transmits it to the display device via the second communication link, enabling wireless screen casting without direct connection between source and display devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If application installation is required for screen casting, then casting functionality is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvecasting functionalityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The screen casting apparatus provides universal screen casting functionality that works across different device types and communication protocols. It supports multiple communication links and can cast various types of screen information (videos, images, text) without requiring device-specific applications, making the system universally applicable and easy to use.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The screen casting apparatus automatically manages the screen casting process by establishing communication links, receiving screen casting information, processing the data, and transmitting it to the display device. The system performs self-configuration and self-management, eliminating the need for users to manually install or configure applications.

Inventive Principle:
Principle #25Self-service
