Sliding Camera Lens Protection Cover for Mobile Phone Shells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing importance of camera functionality in mobile phones necessitates a protection solution to prevent camera damage from scratches and collisions, which existing mobile phone shells fail to adequately address.
Innovation Solution
A mobile phone shell with a camera protection device featuring a sliding camera lens protection cover and a camera slide base, including positioning bulges and blocking arcs, that securely covers the camera lens to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a mobile phone shell is designed without a dedicated camera protection device, then the shell structure remains simple, but the camera lens is vulnerable to scratches and collisions
Solution Approach 1:
The shell is divided into functional modules: a camera slide base with positioning bulges, a camera lens protection cover with positioning slots, and blocking arcs. This segmentation allows the protection mechanism to be added as a modular component rather than redesigning the entire shell, thus improving camera protection while controlling overall structural complexity
Solution Approach 2:
The camera lens protection cover is designed to slide between two positions (covering and exposing the camera lens) through the camera slide base. This dynamic design allows the protection cover to be movable rather than fixed, providing flexibility for both protection and access while maintaining a relatively simple shell structure
2Reliability
If a camera lens protection cover is added to protect the camera, then the camera is protected from damage, but the shell structure becomes more complex
Solution Approach 1:
The camera lens protection cover is nested within the camera slide base, which itself is integrated into the mobile phone shell. The positioning slots and positioning bulges create a nested fitting relationship that secures the protection cover in place. This nesting approach allows multiple protective and structural functions to be combined in a compact arrangement, improving reliability while minimizing the increase in overall structural complexity
3Stability of the object's composition
If positioning mechanisms (positioning bulges and positioning slots) are implemented, then the protection cover is securely locked in place, but the manufacturing precision requirements increase
Solution Approach 1:
The positioning bulges and positioning slots are designed with specific local geometric features that create a precise fit at the interface between the camera slide base and the protection cover. By concentrating the precision requirements to these localized positioning features rather than requiring high precision across the entire assembly, the design achieves stable positioning while managing manufacturing precision requirements
4Stability of the object's composition
If blocking arcs are added to prevent forward and backward movement, then the protection cover is securely constrained, but the device complexity increases
Solution Approach 1:
The blocking arcs are pre-formed as integral features of the camera slide base structure, positioned to automatically engage with the camera lens protection cover when it is installed. This preliminary configuration of the blocking arcs eliminates the need for additional separate components or complex adjustment mechanisms, achieving effective movement constraint while keeping the overall device complexity low

AI summary
Provided is a mobile phone shell with a camera protection device, comprising a mobile phone shell body, and further comprising a camera slide base fixed on the mobile phone shell body and a camera lens protection cover capable of sliding in the camera slide base; the camera slide base comprises two sliding slots arranged oppositely and positioning bulges arranged at two opposite ends in the sliding slot; and each side of the camera lens protection cover is provided with a positioning slot matched with the positioning bulge. The mobile phone shell achieves a function of protecting a mobile phone camera through an assembly structure of the camera lens protection cover and the camera slide base, thus preventing the camera from being scraped or smashed.
