Camera Decoration Structure That Preserves Battery Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in length of the camera decoration member in electronic devices reduces the capacity of the battery compartment, compromising battery life, and there is a risk of components moving towards the battery under external forces, affecting reliability.
Innovation Solution
The camera decoration member is extended to cover part of the battery compartment in the thickness direction, with a barrier wall and support member to prevent movement and deformation, and a force release portion to dissipate external forces, enhancing mounting reliability and battery capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the length of the camera decoration member is increased to accommodate functional devices, then the mounting capability is improved, but the length of the battery compartment is reduced, decreasing battery capacity
Solution Approach 1:
The camera decoration member extends in the thickness direction (Z-axis) rather than only in the length direction (X-axis), allowing functional devices to be mounted above the battery compartment. This dimensional change enables both increased mounting capability and preserved battery capacity by utilizing three-dimensional space efficiently.
2Adaptability or versatility
If the camera decoration member is extended to cover part of the battery compartment, then the mounting capability is improved, but the risk of components moving towards the battery under external forces increases, affecting reliability
Solution Approach 1:
The barrier wall is pre-configured to extend from the middle frame into the battery compartment, creating a preliminary protective structure that prevents the camera decoration member and functional devices from moving towards the battery under external forces. This preemptive measure addresses the reliability concern before it can manifest.
Solution Approach 2:
The barrier wall acts as an intermediary structure between the camera decoration member and the battery compartment, physically separating them and preventing direct contact or movement that could compromise battery safety while allowing the camera decoration member to extend over the battery area.
3Reliability
If the barrier wall is added to support the rear cover assembly, then the reliability is improved by preventing component movement, but the device complexity increases
Solution Approach 1:
The barrier wall serves multiple functions simultaneously: it supports the rear cover assembly, prevents the camera decoration member from moving towards the battery, and structurally separates the mainboard compartment from the battery compartment. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

AI summary
Embodiments of this application provide an electronic device, including a housing, where the housing includes a middle frame and a rear cover assembly that are connected, and the rear cover assembly includes a rear cover and a camera decoration member mounted on the rear cover; a functional device and a camera that are mounted on the camera decoration member; and a battery and a mainboard. The housing has a first accommodating cavity configured to accommodate the mainboard and a second accommodating cavity configured to accommodate the battery. A part that is of the camera decoration member and that is configured to mount the functional device extends to above the second accommodating cavity. The middle frame includes a barrier wall. The barrier wall is located between the first accommodating cavity and the second accommodating cavity, and the barrier wall supports the rear cover assembly. The part of the camera decoration member extends to above the second accommodating cavity. In this way, a length of the camera decoration member is increased, and a length of the second accommodating cavity is not reduced, which helps increase a capacity of the battery. The barrier wall supports the rear cover assembly. This reduces a risk that reliability is affected when the functional device moves toward the second accommodating cavity under an action of an external force.
