Engineering Contradiction Analysis
1Adaptability or versatility
If a display device supports multiple control mechanisms for different signal sources, then the display device can control multiple electronic devices with different interfaces, but it becomes confusing for users to understand and operate
Solution Approach 1:
The patent introduces an agent program as an intermediary layer between the input device and multiple electronic devices with different interfaces. This agent automatically translates control signals between different communication protocols (HDMI, DisplayPort, USB-C, etc.), allowing users to control multiple devices through a single unified interface without needing to understand the underlying complexity of different connection standards
Solution Approach 2:
The display device is designed with a universal control mechanism that can handle multiple types of electronic devices and communication interfaces through a single agent program. The agent provides multi-functional capability to translate and forward control signals to various devices (electronic whiteboards, projectors, smartphones, tablets, computers) regardless of their specific interface type, making the control system universally applicable
2Device complexity
If the display device uses a generic control signal transmission mechanism, then the device structure remains simple, but it cannot smoothly control signal sources from different image transmission interfaces
Solution Approach 1:
The control mechanism employs dynamic signal routing and protocol translation capabilities. The agent program can adaptively adjust the control signal transmission path and format based on the target device's interface type. When a control signal is received, the agent dynamically determines the appropriate translation and forwarding method for the specific device being controlled, enabling flexible adaptation without hardware changes
Solution Approach 2:
The system changes the parameters of control signals (communication protocol, data format, transmission mode) based on the target device's interface requirements. The agent program modifies signal parameters such as transmission protocol (HDMI CEC, DisplayPort MST, USB Type-C) and data formatting to match the specific interface characteristics of the connected electronic device, enabling compatibility across different interfaces while maintaining a simple underlying hardware structure
