Camera Assembly Mounting Structure for Mainboard Space Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in cameras in mobile phones for improved photography and the use of a 2-cell battery solution for fast charging in mobile phones results in a shortage of space on the mainboard, making it difficult to mount components without compromising charging speed or reducing the number of cameras.
Innovation Solution
An electronic device design that includes a main support with a mounting space, a first steel sheet, and a fixation assembly, which creates a gap between the mounting portion and the main support to accommodate a board-to-board connector, allowing for the outward extension of the camera assembly without increasing transverse space, and uses limit plates and elastic connection pieces to secure the camera assembly in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of cameras is increased to improve photographing performance, then photographing performance is improved, but space on the mainboard is reduced
Solution Approach 1:
The patent creates a gap between the mounting portion and the first face of the main support, utilizing the longitudinal dimension (depth) rather than competing for transverse space. This allows the board-to-board connector to be mounted in the gap, effectively adding a mounting dimension without increasing the device's footprint or reducing camera space.
2Speed
If a 2-cell battery solution is used to improve charging speed, then charging speed is improved, but space on the mainboard is reduced
Solution Approach 1:
The patent utilizes the longitudinal space created by the gap between the mounting portion and the main support to accommodate the board-to-board connector for the 2-cell battery solution. This allows fast charging components to be mounted without consuming additional transverse space on the mainboard.
3Adaptability or versatility
If space is increased to accommodate additional components, then component mounting capability is improved, but transverse space of the electronic device is increased
Solution Approach 1:
Instead of increasing transverse space to accommodate additional components, the patent creates longitudinal space by forming a gap between the mounting portion and the main support. The board-to-board connector is mounted in this gap, allowing additional component mounting capability without increasing the device's width or height.

AI summary
An electronic device includes a main support, a first steel sheet, a camera assembly, and a fixation assembly, where the main support is provided with a mounting space, with a first face and a second face that are opposite each other. The first steel sheet is mounted to the first face of the main support and provided with a mounting portion located inside the mounting space. The camera assembly is mounted in the mounting portion, and a fixation assembly is mounted to the second face of the main support to fix the camera assembly in the mounting portion, where a gap is left between the mounting portion and the first face of the main support. The disclosed electronic device can increase space of a downside region of a mainboard, so as to satisfy the need of mounting of components.
