Mobile Phone Idle Screen Image Switching via Closed State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication devices, such as mobile phones, cannot easily change the background image on their idle screens when transitioning between open and closed states, making it complicated for users to alter images, especially those without technical knowledge.
Innovation Solution
A mobile communication device with a closed state detection mechanism, image storage, and a display control system that allows users to select and switch images easily by detecting state changes, enabling the display of new idle screen images when the device opens or closes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional image switching technology is used (switching images when folding mechanism is used or after predetermined time), then images can be switched automatically, but the technology cannot be applied to mobile phones that display idle screens in closed state and causes images to switch in the middle of operation
Solution Approach 1:
The patent applies preliminary action by detecting the closed state before initiating image switching. The control unit checks whether the mobile phone is in a closed state before switching the idle screen image, preventing images from switching in the middle of operation. This preliminary detection ensures that image switching only occurs when appropriate, resolving the reliability issue while maintaining automatic switching capability.
2Adaptability or versatility
If predetermined operations are required to alter idle screen images, then image selection capability is provided, but the operation becomes complicated and users with no knowledge cannot set or alter images
Solution Approach 1:
The patent applies self-service by enabling users to alter idle screen images through simple, intuitive operations. The control unit allows image switching when the mobile phone transitions from closed to opened state, which is a natural and simple operation for users. This eliminates the need for complex predetermined operations while maintaining image selection capability, making the system accessible to users with no technical knowledge.
3Adaptability or versatility
If the folding mechanism is used to change shape, then the device can transition between open and closed states, but images become switched in the middle of operation
Solution Approach 1:
The patent applies feedback by using the state detection unit to continuously monitor whether the mobile phone is in a closed state. This feedback mechanism ensures that image switching only occurs when the phone transitions from closed to opened state, preventing images from switching during operation. The feedback loop maintains operation continuity while preserving state transition capability.

AI summary
A mobile phone including upper and lower portions, a flash memory to store images, a selecting portion to select a target image from the stored images, a closed state detection portion to detect a closed state, and a display control portion to control display of an image to display an image of an idle screen including in a background image the target image selected by the selecting portion when standing by, and the display control portion displays, in response to the change from a state in which the closed state is detected by the closed state detection portion to a state in which the closed state is not detected while the image of the idle screen is being displayed, a new idle screen that includes in the background image a new target image selected by the selecting portion subsequent to the background image included in the idle screen.
