Rotatable Camera FOV Adjustment in Foldable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with fixed camera lenses require users to reorient the device to change the camera's field of view, limiting user convenience when capturing images with foldable displays.
Innovation Solution
A foldable electronic device with a rotatable camera that detects the user's intent and posture, automatically adjusting its orientation using motion and folding angle sensors to change the camera's field of view without needing the user to reorient the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed camera lens is used, then the device structure is simple, but the user must reorient the device to change the camera's field of view, reducing ease of operation
Solution Approach 1:
The camera lens is made rotatable rather than fixed, allowing it to dynamically adjust its orientation independently of the device housing. This enables the camera to capture images from multiple angles without requiring the user to reorient the entire device, directly improving ease of operation while accepting increased device complexity
Solution Approach 2:
The camera system is segmented from the main device body through independent rotation capability. The camera module can rotate separately from the housing structures, allowing the camera's field of view to be adjusted independently without moving the entire device, thus resolving the contradiction between operational ease and device complexity
2Ease of operation
If the camera rotates automatically based on detected posture and folding angle, then image capture convenience is improved, but the extent of automation increases system complexity
Solution Approach 1:
The system uses motion sensors and folding angle sensors to detect the device's posture and folding state, providing feedback to the processor. Based on this feedback, the processor automatically controls the camera's rotation to achieve the desired field of view, improving image capture convenience through automated adjustment
Solution Approach 2:
The camera system serves itself by automatically adjusting its orientation based on sensor detection of device posture and folding angle. The processor interprets sensor data and autonomously controls camera rotation without requiring manual user intervention, enhancing convenience while implementing a degree of automation
