Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to transmit image information, then user convenience is improved, but the image display device remains off requiring manual power activation
Solution Approach 1:
The image receiving device monitors the wireless communication state from the image transmitting device and uses this feedback to automatically control the power state of the image display device. When wireless communication is detected, the system automatically turns on the display device without requiring manual user intervention.
Solution Approach 2:
The image receiving device performs self-service by automatically detecting the wireless communication initiation and autonomously controlling the power state of the image display device. The system serves itself by eliminating the need for external manual power activation through automated detection and control mechanisms.
2Loss of energy
If the image display device is kept in standby state to save power, then energy consumption is reduced, but the device cannot automatically respond to wireless communication initiation
Solution Approach 1:
The image receiving device performs preliminary actions by continuously monitoring the wireless communication state even when the image display device is in standby mode. This allows the system to be prepared to quickly activate the display device when wireless communication is initiated, achieving both energy savings and rapid response.
Solution Approach 2:
The system dynamically adjusts the power state of the image display device based on the wireless communication status. The device transitions between standby and active states according to real-time communication conditions, optimizing both energy consumption and response capability through dynamic state management.

AI summary
An image transmission system includes an image transmitting device coupled to a computer, and an image receiving device coupled to a projector, and transmits image information from the image transmitting device to the image receiving device via wireless communication. The image receiving device detects a state of the wireless communication by the image transmitting device, outputs a first control signal turning on a power of the projector to the projector when detecting that the wireless communication is started, receives the image information transmitted from the image transmitting device, and outputs the received image information to the projector.
