Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing camera modules in electronic devices, such as mobile phones, occupy large space due to multiple camera modules required for various image shooting functions, limiting internal layout and increasing costs.
Innovation Solution
A camera module design that includes a first lens assembly, a light redirecting assembly, and an image sensor, with a second lens assembly that can move between or outside the optical path to switch focal lengths, allowing a single camera module to perform multiple image shooting functions, reducing space occupation and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple camera modules are disposed to meet various image shooting functions, then the image shooting capability is improved, but the space occupied increases and internal layout is limited
Solution Approach 1:
The patent implements multi-functionality by enabling a single camera module to perform multiple image shooting functions (wide-angle, ultra-wide-angle, telephoto) through the movable second lens assembly that can switch between different optical paths and focal lengths, eliminating the need for separate dedicated camera modules for each function
Solution Approach 2:
The patent applies dynamics by making the second lens assembly movable between different positions - it can move into the optical path to enable ultra-wide-angle shooting with a shorter focal length, and move out of the optical path to enable wide-angle shooting with a longer focal length, allowing the camera module to adapt its function dynamically based on shooting requirements
2Adaptability or versatility
If multiple camera modules are disposed to implement zoom function, then the image shooting function is improved, but the device complexity increases
Solution Approach 1:
The patent achieves multi-functionality by designing a single camera module that can perform wide-angle, ultra-wide-angle, and telephoto shooting functions through the movable second lens assembly, which switches between different optical configurations to provide diverse image shooting capabilities without requiring multiple separate camera modules
Solution Approach 2:
The patent combines multiple lens assemblies (first lens assembly and second lens assembly) and the light redirecting assembly into a single integrated camera module structure, merging the functions of what would traditionally require separate camera modules into one unified device, thereby reducing overall device 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

Implementation Method 1
a light redirecting assembly (13), and an image sensor (14), wherein a light incidence side of the light redirecting assembly (13) is opposite to the first lens assembly (11), a light emergence side of the light redirecting assembly (13) is opposite to the image sensor (14), and the light redirecting assembly (13) is configured to redirect, to illuminate the image sensor (14), a light ray that enters the camera module through the first lens assembly (11)

AI summary
A camera module includes a first lens assembly, a light redirecting assembly, and an image sensor. The light redirecting assembly is opposite to the first lens assembly and the image sensor. The camera module further includes a second lens assembly. The second lens assembly moves to an optical path between the first lens assembly and the image sensor or moves outside the optical path when driven by a first driving assembly. When the second lens assembly is located on the optical path, a focal length of the camera module is related to focal lengths of the first lens assembly and the second lens assembly. When the second lens assembly is located outside the optical path, a focal length of the camera module is related to a focal length of the first lens assembly.
