Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile devices, the front camera acts as a design bottleneck due to its fixed position, requiring manual rotation for optimal image and video interaction, which increases user operation complexity and limits the implementation of full-screen designs.
Innovation Solution
A camera apparatus with a rotating mechanism, comprising a camera module, a rotating shaft, a transmission component, and a control mechanism, where the control mechanism drives the camera module to automatically rotate after protruding from the device, utilizing a screw rod and gear system to achieve 360-degree rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the front camera is fixed above the display area, then the device structure is simple, but the device cannot achieve full-screen design and requires manual rotation for optimal image interaction
Solution Approach 1:
The camera module is transformed from a fixed static structure to a dynamic one that can automatically rotate and eject. The rotating shaft and transmission component enable the camera to change its position and orientation automatically, providing adaptability for different shooting directions without requiring manual intervention, thus resolving the contradiction between image interaction capability and structure complexity.
Solution Approach 2:
The camera module is equipped with an automatic rotation mechanism driven by the control mechanism and transmission component. Instead of requiring manual rotation by the user, the system performs the rotation operation autonomously based on shooting requirements, reducing user operation complexity while enhancing image interaction capability.
2Ease of operation
If manual rotation of the camera is required, then the structure is simpler, but user operation complexity increases
Solution Approach 1:
The rotation mechanism is designed to operate automatically without user intervention. The control mechanism activates the transmission component, which in turn rotates the camera module via the rotating shaft. This self-service approach eliminates the need for manual rotation operations, significantly improving ease of operation despite the added mechanical complexity.
Solution Approach 2:
The manual mechanical rotation operation is replaced with an automated control system. The control mechanism, screw rod, and gear system work together to substitute human hand operations with an automated mechanical system, making the camera rotation transparent to the user and improving operational ease.
3Ease of operation
If the camera module is ejected and rotated automatically, then user operation complexity is reduced, but the device complexity increases
Solution Approach 1:
The ejection and rotation functions are merged into a single integrated mechanism. The transmission component simultaneously performs both ejection (moving the camera module outward) and rotation (orienting it in the correct direction) through coordinated action of the screw rod and gears, reducing the need for separate mechanisms and minimizing overall device complexity.
Solution Approach 2:
The transmission component is designed with multi-functionality, serving both as an ejection mechanism and a rotation mechanism. This universal component approach allows a single mechanical assembly to perform multiple functions, reducing the total number of parts and minimizing device complexity while achieving automatic camera operation.
