Pop-Up Camera Power Control for Full-Screen Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent operation of a driving mechanism to raise and lower a camera in a full-screen terminal increases power consumption, leading to a reduction in the terminal's usage time.
Innovation Solution
Implementing a control method that maintains the camera in a raised or retracted state based on the terminal's remaining power and user demands, using a first operating mode where the driving mechanism ignores certain control instructions to prevent unnecessary raising and lowering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driving mechanism frequently raises and lowers the camera to enable photographing, then the camera functionality is achieved, but the power consumption increases and usage time reduces
Solution Approach 1:
The patent applies dynamics by making the camera module movable between raised and retracted positions through a driving mechanism. The camera can be dynamically adjusted based on operational needs, allowing it to be raised when photographing is required and retracted when not needed, thereby balancing functionality with power conservation.
Solution Approach 2:
The patent implements periodic action by repeatedly raising and lowering the camera module based on periodic photographing operations. The driving mechanism activates periodically to raise the camera before each photographing session and after completion, creating a cyclic pattern of movement that enables functionality while minimizing continuous power consumption.
2Productivity
If the driving mechanism frequently raises and lowers the camera, then the camera can be used for photographing, but the usage time of the terminal reduces
Solution Approach 1:
The dynamic positioning of the camera module allows it to be raised only when photographing operations are needed and retracted during non-photographing periods. This dynamic adjustment enables multiple photographing sessions while managing the overall duration of motor activation to preserve battery life and extend usage time.
Solution Approach 2:
The periodic raising and lowering of the camera module aligns with periodic photographing needs. By activating the driving mechanism only during necessary photographing intervals and keeping it retracted otherwise, the system maintains productivity for multiple operations while limiting the cumulative duration of high-power motor operation to extend overall usage time.
3Shape
If the camera is designed as a raising-lowering type to maintain screen-to-body ratio, then the aesthetic design is achieved, but the power consumption increases due to frequent driving mechanism operation
Solution Approach 1:
The camera module is designed with dynamic raising and lowering capability, allowing it to be positioned out of the way during non-use to maintain the terminal's sleek screen-to-body ratio aesthetic. The driving mechanism activates only when photographing is needed, enabling the device to transition between a compact aesthetic form and a functional photographing state, thereby preserving energy by avoiding continuous motor operation.
