Display Wireless Interface Power Control via User Menu
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless/optical display systems consume excessive power due to the need to turn on or off both the display apparatus and the wireless set-top box using a remote controller, leading to increased energy consumption.
Innovation Solution
A display apparatus with a user interface that allows users to selectively power on or off the wireless/optical module through a menu, enabling controlled power supply to the wireless/optical interface based on user selection, and transmitting control signals to external apparatuses to manage power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless set-top box is turned on or off together with the display apparatus using a remote controller, then the wireless/optical communication function is maintained, but power consumption increases
Solution Approach 1:
The patent segments the power control of the wireless/optical module from the main display apparatus power control. The wireless/optical interface can be independently powered on or off through a user menu, separate from the main display apparatus power state. This allows the wireless communication function to be maintained while the display apparatus is off, or the wireless module to be turned off to save power when not needed, resolving the contradiction between maintaining communication reliability and reducing power consumption.
2Reliability
If the wireless/optical module is always powered on to maintain communication capability, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic power control for the wireless/optical module through a user menu interface. Users can dynamically adjust the power state of the wireless/optical interface based on their needs - turning it on when communication is required and turning it off to save power when not needed. This dynamic control mechanism resolves the contradiction by allowing the system to adapt its power consumption level according to actual communication requirements rather than maintaining a fixed power state.
