Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices, such as smartphones, only shoot time-lapse videos with a fixed viewing angle and fail to capture a sense of speed, limiting the interest and quality of the photographic content.
Innovation Solution
A time-lapse photographic device equipped with a camera module, a drive module for rotation, and a control unit that generates intermittent drive signals to control the camera's angle of view based on environment detection signals, ensuring improved viewing angles and quality by adjusting the shooting intervals and exposure times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera module uses a fixed viewing angle for time-lapse photography, then the device structure is simple, but the video content lacks dynamic interest and quality
Solution Approach 1:
The patent applies the dynamics principle by making the camera module rotatable to change its viewing angle dynamically during time-lapse photography. The camera module can rotate around a rotation axis under the control of a drive module, allowing the viewing angle to vary over time. This dynamic adjustment transforms the previously static camera structure into a flexible system that can capture diverse perspectives, thereby improving video quality and dynamic interest without significantly complicating the overall device structure.
2Productivity
If the camera module rotates to change viewing angles, then the video dynamic interest is improved, but the device complexity increases
Solution Approach 1:
The patent merges the camera module with the rotation mechanism by integrating the drive module directly with the camera module. The drive module is configured to drive the camera module to rotate around a rotation axis, combining the functions of camera mounting and rotation actuation into a unified structure. This integration reduces the need for separate complex mounting mechanisms and control systems, thereby achieving dynamic viewing angle changes while minimizing the increase in device complexity.
Solution Approach 2:
The drive module serves multiple functions: it not only rotates the camera module to change viewing angles but also controls the rotation speed and angle ranges. This multi-functionality reduces the need for additional dedicated components for each function, thereby achieving enhanced video quality without proportionally increasing device complexity.
3Manufacturing precision
If the camera shoots continuously at high frequency, then the time-lapse video quality is improved, but the energy consumption increases
Solution Approach 1:
The patent applies periodic action by controlling the camera module to shoot images at specific time intervals rather than continuously. The control unit receives rotation angle information from the detection module and determines shooting timing based on the rotation phase. This periodic shooting approach captures key moments during rotation while reducing overall energy consumption compared to continuous high-frequency shooting, thereby maintaining video quality while improving energy efficiency.
