Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for multiple cameras in electronic devices leads to a larger space requirement, compromising the miniaturization and efficient use of space within the device.
Innovation Solution
A camera assembly design featuring first and second holders with protrusions arranged in a staggered and stacked manner, reducing overall size by utilizing common edge space and enabling modular integration, while maintaining camera functionality and providing space for other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of cameras are installed to meet different application scenarios, then camera functionality is improved, but the space occupied by the camera module increases
Solution Approach 1:
The patent applies nesting by placing the second holder inside the first holder, with the second holder containing the second camera and being positioned within the spatial envelope of the first holder. This nested configuration allows multiple cameras to coexist in a compact arrangement, reducing the overall camera module area while maintaining the functionality of multiple cameras for different application scenarios
Solution Approach 2:
The patent transitions from a planar side-by-side arrangement to a three-dimensional stacked configuration. The first holder and second holder are arranged in different layers along the thickness direction, with protrusions and recesses enabling vertical stacking. This dimensional change allows multiple cameras to be packed more efficiently in the Z-direction rather than spreading them out in the X-Y plane, thereby reducing the camera module footprint
2Quantity of substance
If the camera module occupies larger space, then more cameras can be accommodated, but the miniaturization of the electronic device is compromised
Solution Approach 1:
The second holder is nested within the first holder structure, with the second camera positioned inside the spatial boundaries of the first holder. This nesting enables accommodation of multiple cameras (increasing quantity) while containing them within a compact volume, directly addressing the contradiction between camera quantity and module volume
Solution Approach 2:
By stacking holders in the thickness direction rather than arranging them laterally, the patent exploits the Z-dimension to increase camera quantity without proportionally increasing the X-Y footprint or overall volume. The protrusion-recess interface enables this vertical stacking, allowing more cameras to be packed into the same or reduced volume
3Area of stationary object
If holders are arranged in a staggered and stacked manner, then space utilization is improved, but manufacturing complexity increases
Solution Approach 1:
The camera module is segmented into separate first holder and second holder components, each with integrated protrusions and recesses. This segmentation allows for modular manufacturing where each holder can be produced independently using standard molding techniques, then assembled together. The protrusion-recess features are built-in during molding rather than requiring complex post-assembly operations, balancing space-efficient staggered stacking with manufacturing ease
Solution Approach 2:
The protrusion and recess features are merged into the holder structures themselves during the molding process, rather than being separate components. This integration simplifies assembly by eliminating additional fastening steps or alignment operations, making the staggered stacked arrangement manufacturable without excessive complexity while achieving superior space utilization

AI summary
A camera assembly includes a first holder, a second holder, a first camera, and a second camera, where the first camera is disposed on the first holder, and the second camera is disposed on the second holder; and the second holder is disposed adjacent to the first holder. The first holder is provided with a first protrusion extending towards the second holder. The second holder is provided with a second protrusion extending towards the first holder. The first protrusion and the second protrusion are disposed in a staggered and stacked manner.
