Solution Overview
Problem
Dual lens cameras with fixed-focus lens modules have a high minimum depth of field, limiting their ability to capture images of near scenes, and using zoom lens modules increases manufacturing costs and reduces image quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed-focus lens modules are used, then the structure is simple and manufacturing cost is low, but the minimum depth of field is high and near scenes cannot be captured
Solution Approach 1:
The patent applies the dynamics principle by making the lens modules tiltable relative to the support frame through a tilting mechanism. The lens modules can rotate around a tilt axis, changing their optical axis angle dynamically. This allows the depth of field to be adjusted from a fixed state to a variable state, enabling capture of both distant and near scenes while maintaining manufacturing simplicity.
Solution Approach 2:
The patent changes the orientation parameter of the lens modules by introducing a tilt angle. By adjusting the tilt angle of the lens modules relative to the support frame, the effective focal length and depth of field parameters are modified. This allows a single fixed-focus lens module to achieve variable depth of field effects without changing the lens itself.
2Adaptability or versatility
If zoom lens modules are used to adjust depth of field, then the depth of field becomes adjustable, but the manufacturing cost increases and image quality decreases
Solution Approach 1:
Instead of using complex zoom lens modules with multiple movable lens elements, the patent employs a simple tilting mechanism that rotates the entire lens module. This dynamic adjustment changes the effective field of view and depth of field by altering the lens orientation, achieving the same functional result with significantly reduced complexity and cost.
Solution Approach 2:
The patent extracts the essential function of depth of field adjustment from the complex zoom lens mechanism. By separating the lens module from the support frame and allowing independent tilting motion, the patent achieves depth of field adjustment without requiring the multiple lens elements and complex mechanical structures of traditional zoom lenses.
3Adaptability or versatility
If zoom lens modules are used to adjust depth of field, then the depth of field becomes adjustable, but the image quality becomes relatively low
Solution Approach 1:
The tilting mechanism allows precise control of the lens orientation angle, enabling accurate adjustment of the depth of field. The dynamic positioning capability ensures that the lens can be held at specific tilt angles to capture images at different depths, maintaining image quality through controlled, precise positioning rather than complex optical adjustments.

Function Achieved in This Case
The tilting mechanisms effectively adjust the depth of field, allowing the camera to capture images of very near scenes without increasing manufacturing costs or compromising image quality, by using shape memory alloy adjusting lines that change length in response to temperature changes.
