Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional optical anti-shake component is used, then image stabilization is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the anti-shake function with the existing lens barrel structure by integrating the driving component into the lens component assembly. The lens component itself serves as part of the anti-shake mechanism, eliminating the need for separate complex optical anti-shake components while achieving image stabilization through rotation of the lens barrel around the optical axis.
Solution Approach 2:
The lens component is designed to serve multiple functions: it performs both optical focusing and anti-shake operations. The same lens barrel that holds the lenses also acts as the rotating element for stabilization, and the driving component serves both autofocus and anti-shake functions, reducing overall system complexity.
2Reliability
If a traditional optical anti-shake component is used, then image stabilization is improved, but assembly difficulty increases
Solution Approach 1:
The patent merges the anti-shake mechanism with the lens assembly, so that the lens barrel serves as both the optical housing and the anti-shake rotating element. This integration reduces the number of separate components that need to be assembled, simplifying the manufacturing process while maintaining effective image stabilization.
3Volume of moving object
If a two-axial correction structure is used, then miniaturization is achieved, but structure complexity remains high
Solution Approach 1:
The patent extracts the essential anti-shake function from complex multi-axial correction mechanisms and implements it through a simpler single rotational degree of freedom around the optical axis. By taking out only the necessary stabilization function and implementing it through lens barrel rotation, the design achieves miniaturization while avoiding the structural complexity of two-axial correction systems.
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 anti-shake function is achieved with a simplified design that reduces costs and assembly difficulty, while maintaining effective image stabilization by compensating for user-induced shaking.
Implementation Method 1
The driving component is connected to the slider so as to drive the slider to move. There is an acute angle between extending directions of the first fitting portion and the second fitting portion, and both the extending directions are inclined relative to a direction of an optical axis of the lens component. By making the driving component drive the slider to move, the optical axis of the lens component can rotate relative to the module holder.
Implementation Method 2
In the process of shooting with the above-mentioned camera module, if the camera module shakes due to user shaking, the slider can be driven to move through the driving component, so that the camera produces shaking opposite to the shaking, so as to compensate for relative rotation between the optical axis of the camera module and a viewfinder area caused by the user shaking
