Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing installation of front-facing and rear-facing cameras in mobile terminals requires two separate mounting holes on the main circuit board, leading to a large installation clearance that occupies valuable space and affects the installation of other components.
Innovation Solution
An image shooting apparatus with a support base, an image shooting circuit board that divides into two accommodating chambers, and two image shooting assemblies with lenses oriented in opposite directions, allowing both assemblies to share a single mounting hole and reduce space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate camera modules (front-facing and rear-facing) are installed in a mobile terminal, then the shooting function in different usage scenes is satisfied, but a large installation clearance is occupied on the main circuit board
Solution Approach 1:
The patent combines the front-facing camera module and rear-facing camera module into a single integrated camera module. The first image shooting assembly (front camera) and second image shooting assembly (rear camera) are mounted on opposite sides of the same circuit board, sharing a common mounting location. This merging approach maintains the ability to shoot in different usage scenes while reducing the total installation clearance occupied on the main circuit board from two separate holes to one shared hole.
2Ease of operation
If two separate mounting holes are provided on the main circuit board for front-facing and rear-facing cameras, then both cameras can be installed, but the installation of other parts is affected due to space occupation
Solution Approach 1:
The patent merges the mounting requirements of two separate cameras into a single integrated camera module that occupies one mounting location on the circuit board. This reduces the number of mounting holes from two to one, thereby freeing up space and reducing constraints on the installation of other parts in the mobile terminal while maintaining ease of camera installation through the integrated design.
3Adaptability or versatility
If front-facing camera and rear-facing camera are installed in existing mobile terminal, then shooting requirements in different scenes are met, but space utilization is reduced
Solution Approach 1:
The patent utilizes the third dimension (depth/thickness) by mounting image shooting assemblies on both sides of the circuit board. The first image shooting assembly is disposed on one side of the circuit board while the second image shooting assembly is disposed on the opposite side, effectively using the Z-axis dimension to accommodate both cameras within a compact footprint, thereby improving space utilization while meeting shooting requirements in different scenes.
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
This configuration reduces the space occupied by cameras, improves space utilization, and increases the flexibility of part stacking on the circuit board, enhancing the overall device's compactness and functionality.
Implementation Method 1
The image shooting circuit board comprises a first circuit board, a second circuit board, and a heat conducting layer; the first image sensor is attached to the first circuit board; the second image sensor is attached to the second circuit board; and the heat conducting layer is disposed between the first circuit board and the second circuit board

AI summary
This disclosure provides an image shooting apparatus and a mobile terminal. The image shooting apparatus includes: a support base, an image shooting circuit board, a first image shooting assembly, and a second image shooting assembly. The support base is provided with an accommodating chamber. The image shooting circuit board is disposed in the accommodating chamber, and divides the accommodating chamber into a first accommodating chamber and a second accommodating chamber. The first image shooting assembly is disposed in the first accommodating chamber, and the second image shooting assembly is disposed in the second accommodating chamber. The first image shooting assembly includes a first lens and a first image sensor, where the first image sensor is attached to a first side of the image shooting circuit board, and the first image sensor receives an incident light passing through the first lens for imaging. The second image shooting assembly includes a second lens and a second image sensor, where the second image sensor is attached to a second side of the image shooting circuit board, and the second image sensor receives an incident light passing through the second lens for imaging. As such, space occupied by the image shooting apparatus in the mobile terminal may be reduced.
