Slide Mechanism Power Control for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable integrated devices of the slide type turn off all functions when the sliding part is closed, preventing the use of camera functions and other features like music playback and voice recording.
Innovation Solution
A method and device that determine the opening or closing of a slide to control power based on function modes, allowing camera functions to be turned off while maintaining power for non-camera modes like music playback and data storage when the slide is closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If power is turned off when the sliding part is closed, then power consumption is reduced, but all functions including non-camera functions become unavailable
Solution Approach 1:
The patent segments the power control into different functional modules: camera functions are turned off when the sliding part is closed, while non-camera functions (music playback, voice recording, data storage) maintain power. This is achieved by dividing the power supply control into separate control paths for different functional modules based on the sliding part position and current operation mode.
2Device complexity
If all functions are turned off when the slide is closed, then device complexity is reduced, but user convenience deteriorates
Solution Approach 1:
The system automatically determines the current operation mode and selectively controls power to different functions based on the sliding part position, without requiring manual user intervention. The controller automatically switches between camera mode and non-camera mode, and adjusts power supply accordingly, making the system self-adaptive to user needs.
3Device complexity
If the sliding part controls all functions, then device structure is simplified, but functional flexibility is reduced
Solution Approach 1:
The patent implements dynamic power control where the system adapts its power supply configuration based on real-time conditions (sliding part position and current operation mode). The controller dynamically adjusts which functions receive power, transitioning between different power states without requiring physical reconfiguration of the device structure.

AI summary
A portable integrated device and a method of controlling power thereof. The method of controlling power to a digital integrated device which includes a first body and a second body slidingly attached to each other and a first mode and a second mode including sliding the first body relative to the second body from an open position to a closed position, turning off power of the digital integrated device in the first mode, and maintaining the power of the digital integrated device in the second mode. Accordingly, power control may be performed differently according to whether the sliding part is open or closed and whether the preset function mode of the portable integrated device is a camera mode or a non-camera mode, so that functions of the non-camera modes can be maintained even when the sliding part is closed.
