Mobile Terminal Decoration Component for Camera Module Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing mobile phone back covers with camera modules result in complex structures and low yield due to the need for punching protrusions, which can lead to defects like cracks and wrinkles.
Innovation Solution
A decoration component and housing component design featuring a first and second decoration enclosure with through-holes, allowing the camera module to protrude without directly punching the housing, simplifying the structure and improving yield by providing additional space for the camera module while maintaining the original protrusion function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If punching protrusions are provided on the back cover to accommodate the camera module, then the camera module can be accommodated and the overall thickness is reduced, but the structure becomes complicated and manufacturing yield decreases
Solution Approach 1:
The back cover is divided into a housing component and a decoration component that are assembled together. The decoration component is separately manufactured and then attached to the housing, allowing each component to be optimized independently and simplifying the overall manufacturing process while maintaining the protrusion function.
Solution Approach 2:
The protrusion function is extracted from the housing component and transferred to the decoration component. The decoration component includes a receiving groove that receives the camera module, while the housing only provides the through-hole, separating the structural and decorative functions.
2Volume of moving object
If punching protrusions are provided on the back cover, then the camera module can be accommodated, but defects like cracks and wrinkles occur and manufacturing yield is low
Solution Approach 1:
The back cover manufacturing is segmented into two independent processes: manufacturing the housing with through-hole and manufacturing the decoration component with receiving groove. This avoids the need to punch protrusions directly on the housing, eliminating the associated defects.
Solution Approach 2:
The decoration component acts as an intermediary between the housing and the camera module. It provides the receiving groove that accommodates the camera module without requiring direct punching of the housing, thus preventing cracks and wrinkles.
3Length of stationary object
If the camera module protrudes through the back cover, then the overall thickness is reduced, but the housing structure becomes complicated
Solution Approach 1:
The back cover system is segmented into a simple housing structure and a separate decoration component. The housing only needs a through-hole and mounting groove, while the decoration component provides the receiving groove and protrusion, simplifying the housing structure.
Solution Approach 2:
The solution moves from modifying the housing in three dimensions (punching protrusions) to adding a separate decoration component in another dimension (assembled on the housing surface). This maintains the thickness reduction while simplifying the housing structure.

AI summary
The present disclosure provides a decoration component. The decoration component includes a first decoration enclosure, a second decoration enclosure, and a cover. The first decoration enclosure has a first through-hole and a receiving groove surrounding the first through-hole. The second decoration enclosure is received in the receiving groove and protrudes beyond the receiving groove in an axial direction of the first through-hole, and the second decoration enclosure has a second through-hole corresponding to the first through-hole. The cover is coupled at a side of the second decoration enclosure facing away from the first decoration enclosure, and the cover covers the second through-hole. The present disclosure further provides a housing component and a mobile terminal.
