Solution Overview
Problem
Conventional technologies struggle with automatically switching to the correct screen corresponding to an external device when it is powered on or off, and fail to identify and control the appropriate device if components are in a sleep state or disconnected.
Innovation Solution
An electronic device with communication interfaces, a memory, and a processor that identifies and controls external devices and input devices based on mapping information, allowing automatic switching and power management based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional automatic switching is implemented when external device power is powered on, then switching to the correct screen is improved, but the system fails to handle cases where the external device is already powered on or disconnected
Solution Approach 1:
The system performs preliminary detection of external device connection status and power state before attempting automatic switching. The processor checks whether the external device is connected and powered on before triggering screen switching, preventing failed switching attempts and improving system reliability.
Solution Approach 2:
The system continuously monitors the connection status and power state of external devices, using feedback from detection circuits to dynamically adjust switching behavior. This feedback mechanism ensures the system responds accurately to current device states, resolving the contradiction between automation and reliability.
2Measurement precision
If manual device selection is required among multiple external devices and input devices, then device control precision is improved, but user convenience deteriorates due to the need to select both external device and input device
Solution Approach 1:
The system merges the selection of external devices and input devices into a unified automatic switching process. When an external device is detected, the system automatically switches both the display screen and the associated input device, eliminating the need for separate manual selections and improving user convenience while maintaining control precision.
Solution Approach 2:
The system creates a universal mapping relationship between external devices and input devices, where each external device is associated with a corresponding input device. This multi-functional approach allows a single detection event to trigger coordinated switching of both device types, resolving the contradiction between precision and ease of operation.
3Loss of energy
If components operate in sleep state to save energy, then power consumption is reduced, but the system cannot effectively identify or control devices in sleep state
Solution Approach 1:
The system performs preliminary detection of external devices in sleep state using low-power detection circuits before full activation. This allows the system to identify connected devices even when they are in sleep mode, maintaining detection capability while preserving energy savings from sleep operation.
Solution Approach 2:
The system introduces an intermediary detection mechanism that can communicate with external devices in sleep state without fully waking them. This intermediary layer enables device identification and basic control while maintaining the energy-saving sleep state, resolving the contradiction between power consumption and detection capability.
