Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in determining the operational state of a display device when the entire display area is drawn into the housing, and the presence of external devices that can interwork with the display device is not easily recognized, leading to potential user inconvenience and unnecessary power consumption.
Innovation Solution
A display device equipped with a motion recognition sensor, wireless communication unit, and controller to detect user presence and connected external devices, outputting alarms only when necessary to inform the user of the device's operable state and minimize power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the entire display area is drawn into the housing to achieve a compact structure, then the device can serve as a speaker only, but it becomes difficult for the user to know what state the display device is in
Solution Approach 1:
The patent employs LED indicators that change color or illuminate to communicate the operational state of the display device when the display is retracted into the housing. These visual indicators provide state information (such as power status, connection status, or operational mode) without requiring the display to be visible, thus resolving the contradiction between compactness and information visibility.
2Ease of operation
If alarms are continuously output to inform users of device state, then user convenience is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic detection of user presence using motion recognition sensors, and only outputs alarms when users are detected. The system alternates between active detection periods and standby periods, thereby providing user convenience through timely notifications while significantly reducing power consumption by avoiding continuous alarm output or constant sensor operation.
3Measurement precision
If motion recognition sensors and wireless communication units are added to detect user presence and external devices, then accuracy of user recognition and device interworking is improved, but device complexity increases
Solution Approach 1:
The patent integrates motion recognition sensors and wireless communication units into the existing display device framework, allowing these components to serve multiple functions: user presence detection, external device identification, and operational state communication. By making the system multi-functional rather than adding separate dedicated systems, the patent improves recognition accuracy while minimizing the increase in overall device complexity.
