Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device executes cloud games through streaming from a remote server, then high-quality game content can be enjoyed without requiring high-performance hardware, but the device lacks capability to share game screens and control signals with other users for collaborative gameplay
Solution Approach 1:
The display device is enhanced with communication interfaces and processors that enable it to perform multiple functions: executing cloud games locally, sharing game screens with other devices, receiving and transmitting control signals, and facilitating collaborative gameplay. This multi-functionality transforms a single-user cloud gaming device into a versatile platform that supports both local and shared gaming experiences.
Solution Approach 2:
The patent introduces communication interfaces and processors as intermediary components that mediate between the display device and external devices (smartphones, tablets, etc.). These intermediaries enable the display device to share game screens and receive control signals from other users' devices, facilitating collaborative gameplay without requiring direct peer-to-peer connections between all users.
2Adaptability or versatility
If the display device transmits game screens to second display devices for sharing, then multiple users can play together, but compatibility issues arise between different controller formats
Solution Approach 1:
The processor detects the type of control signal received from different controllers and automatically converts it to a standardized format suitable for transmission to the game server. This parameter transformation ensures that control signals from various controller formats (different protocols, button layouts, input methods) are normalized and compatible with the cloud gaming platform's requirements.
Solution Approach 2:
The display device acts as an intermediary that receives control signals from diverse controller formats, processes and standardizes them through its processor, and then transmits the unified control signals to the game server. This intermediary processing layer resolves compatibility issues between different controller types and the cloud gaming platform.
3Adaptability or versatility
If the display device receives control signals from second display devices, then collaborative control is enabled, but the system requires complex communication protocols to ensure proper signal transmission and processing
Solution Approach 1:
The display device serves as a communication intermediary between multiple users' devices and the cloud gaming server. It receives control signals from various input devices, processes them through standardized protocols, and transmits them to the server. This intermediary role simplifies the overall system architecture by centralizing communication protocol handling in the display device rather than requiring each user device to implement complex protocols.
Solution Approach 2:
The display device is designed with universal communication capabilities that allow it to handle multiple types of control signals from different input devices (controllers, keyboards, mice, etc.). This universal interface approach enables multi-user collaborative control without requiring separate specialized protocols for each input method.
