Foldable Electronic Device Support Detection for Video Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, particularly smartphones, lack a user-friendly mechanism to transition seamlessly into a video recording mode when used in a camcorder-like orientation, making it difficult to initiate and control video recording without physical keys or awkwardly tapping display targets.
Innovation Solution
An electronic device with a pivotable housing and sensors that detect a deformed geometric form factor and camcorder support condition automatically initiates a video recording mode, allowing gesture-based control through rotational lifting and orthogonal angle manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional smartphone design with fixed form factor is used, then device simplicity is maintained, but ease of operation for video recording in camcorder orientation is poor
Solution Approach 1:
The patent applies the dynamics principle by making the device form factor changeable through a hinge mechanism that allows the housing to pivot between closed, open, and partially deformed positions. This dynamic structural change enables the device to adapt to different operational modes, specifically optimizing for camcorder-style video recording when in the partially deformed geometric form factor, thereby resolving the contradiction between ease of operation and device complexity.
2Ease of operation
If physical keys or display tapping is required to initiate video recording, then device simplicity is maintained, but ease of operation for video recording is poor
Solution Approach 1:
The patent applies the self-service principle by enabling the device to automatically detect when it is being held in a camcorder support condition and autonomously initiate video recording mode without requiring user interaction through physical keys or display tapping. The sensor system detects the support condition and automatically enables the video recording mode of operation, allowing the device to serve itself and eliminating the need for additional control interfaces.
3Ease of operation
If automatic detection of camcorder support condition is implemented, then ease of operation for video recording is improved, but device complexity increases
Solution Approach 1:
The patent applies the mechanics substitution principle by replacing traditional mechanical control interfaces (physical keys, buttons, or manual display interaction) with an automated sensor-based detection system. Sensors detect the geometric form factor and camcorder support condition, and the processor automatically initiates video recording mode based on these detections, substituting mechanical user interaction with an automated sensing and control system.

AI summary
A method in an electronic device includes detecting, with at least a first sensor, a first device housing of the electronic device being pivoted about a hinge relative to a second device housing to a deformed geometry where the first device housing and second device housing define a substantially orthogonal angle. The method includes detecting, with at least a second sensor, a rotational lifting operation of the electronic device in three-dimensional space. In response to the at least a first sensor detecting the deformed geometry and the at least a second sensor detecting the rotational lifting operation, the method includes causing, with one or more processors, an image capture device of the electronic device to enter a video recording mode of operation.
