Dual-Axis Reflective Module Assembly for Camera Shake Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules face challenges in precisely correcting shake during image or video capturing, especially when the subject moves, requiring users to manually adjust the camera's direction, which can be inconvenient and difficult to achieve accurate capturing.
Innovation Solution
A reflective module assembly with a housing containing a first reflective module and a second reflective module, each rotatable about distinct axes, supported by ball members and guide portions, interacts with magnets and coils to change the light path, allowing for precise adjustment and stabilization of the camera's focus, enabling effective shake correction and subject tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single reflective module is used for shake correction, then the structure is simple, but the shake correction precision is insufficient
Solution Approach 1:
The reflective module is divided into two independent reflective modules (first and second), each capable of rotating about different axes. This segmentation allows each module to independently correct shake in different directions, thereby improving overall shake correction precision while maintaining reasonable structural complexity through modular design
2Measurement precision
If manual adjustment is required to track moving subjects, then the device structure is simple, but the ease of operation deteriorates and capturing accuracy is reduced
Solution Approach 1:
The reflective modules are designed to be rotatable about different axes, enabling dynamic adjustment of the light path. This dynamic capability allows the system to automatically track moving subjects by adjusting the reflection angle, eliminating the need for manual device repositioning and thereby improving both ease of operation and subject tracking accuracy
3Adaptability or versatility
If the reflective module rotates about a single axis, then the mechanism is simple, but the adaptability to correct multi-directional shake is limited
Solution Approach 1:
The first and second reflective modules are configured to rotate about different axes (first axis and second axis respectively), creating an asymmetric rotation configuration. This asymmetric design enables the system to correct shake in multiple directions simultaneously, improving adaptability to multi-directional shake while the modular nature keeps the overall mechanism manageable
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The reflective module assembly effectively corrects user-induced shake and tracks moving subjects, ensuring accurate image or video capture by dynamically adjusting the light path, thereby enhancing the camera's stability and capturing capabilities.
Implementation Method 1
a first reflective member rotatable about a first axis formed by at least two first ball members
Implementation Method 2
a second reflective member rotatable about a second axis, perpendicular to the first axis and passing through a rotation axis ball disposed at the second reflective module
Implementation Method 3
at least two first ball members disposed between the first holder and the housing to rotatably support the first holder about the first axis
