Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera devices with lens modules often produce blurry images due to shaking, necessitating the development of a shockproof zoom lens module to improve image quality.
Innovation Solution
A camera device incorporating a liquid lens and a deforming member, where the first driving module generates relative motion between the liquid lens and the deforming member, allowing the deforming member to deform the liquid lens for focus adjustment and image stabilization by moving along or perpendicular to the optical axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional lens module is used in electronic devices, then the device structure can be kept simple, but the image quality deteriorates when the lens module shakes
Solution Approach 1:
The patent employs a liquid lens that can dynamically change its focal length by deforming its shape. The liquid lens is driven by a driving module that adjusts the position or shape of a deforming member, allowing the lens to adapt its optical properties in real-time to compensate for shaking and maintain image quality
Solution Approach 2:
The patent replaces conventional mechanical lens focusing mechanisms with a liquid lens system that uses electromagnetic driving members to deform the liquid lens surface. This substitution enables more precise and rapid adjustment of focal length while reducing mechanical complexity and improving response to shaking
2Reliability
If a liquid lens with deforming member is introduced to improve focus adjustment, then image quality can be enhanced, but the device complexity increases
Solution Approach 1:
The lens module is segmented into distinct functional components: the liquid lens, the deforming member, and the driving module. This segmentation allows each component to be optimized independently and simplifies the overall structure by assigning specific functions to separate elements rather than using a complex integrated mechanical system
Solution Approach 2:
The deforming member acts as an intermediary between the electromagnetic driving members and the liquid lens. It translates the driving force into controlled deformation of the liquid lens surface, enabling precise focal length adjustment while isolating the liquid lens from direct mechanical contact and reducing complexity
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 solution effectively adjusts focus and stabilizes images, enhancing image quality by allowing the liquid lens to deform in response to the deforming member's movement, thereby reducing blur caused by shaking.
Implementation Method 1
the first driving module comprises a first electromagnetic driving member and a second electromagnetic driving member corresponding to each other
Implementation Method 2
the deforming member deforms the liquid lens
Implementation Method 3
the first driving module comprises at least two first electromagnetic driving members and at least two second electromagnetic driving members corresponding to the first electromagnetic driving members

AI summary
A camera device is provided, including a liquid lens, a deforming member, and a first driving module. The deforming member is disposed adjacent to the liquid lens, and the first driving module can generate relative motion between the liquid lens and the deforming member. In response to the adjustment of the distance between the liquid lens and the deforming member, the deforming member deforms the liquid lens.
