Mobile Phone Camera Lens Protector with Abrasive Blasted Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera lens protecting devices for mobile phones often have unsuitable wiring patterns that do not match the back surface of the phone, lack color options, and are prone to scratches and detachment of the protecting sheet.
Innovation Solution
A camera lens protector assembly with a protector cover treated by an abrasive blasting method to achieve a visually clean and textured surface, allowing for better matching with the mobile phone's rear surface, and featuring through holes for eye members that protect the camera lenses without affecting their optical performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wire drawing treatment procedure is used on the protecting cover, then a wiring pattern is formed on the outer surface, but the wiring pattern does not match the back surface of the mobile phone and cannot provide multiple desired colors
Solution Approach 1:
The patent changes the surface treatment parameter from wire drawing to abrasive blasting, which fundamentally alters the surface profile characteristics. This enables the surface to match the mobile phone's back surface texture while also allowing subsequent electrolytic coloring to achieve multiple desired colors, thus resolving the contradiction between manufacturing simplicity and adaptability.
Solution Approach 2:
The patent combines abrasive blasting treatment with electrolytic coloring to create a composite surface treatment process. The abrasive blasting creates the desired surface profile for matching, while the electrolytic coloring adds multiple color options. This composite approach resolves the contradiction by integrating multiple functions into a unified treatment process.
2Reliability
If a transparent protecting sheet is adhered on the protecting cover, then the camera array is protected, but the protecting sheet may be scratched and slip off from the protecting cover
Solution Approach 1:
The patent extracts and removes the separate transparent protecting sheet from the assembly. Instead, the protector cover itself is designed with abrasive blasted outer surface that provides both structural protection and surface stability, eliminating the need for an additional adhered sheet and thus preventing adhesion-related failures.
Solution Approach 2:
The patent merges the protection function and the surface stability function into a single integrated protector cover structure. The abrasive blasted outer surface of the protector cover simultaneously provides mechanical protection and ensures stable attachment to the mobile phone, eliminating the separate protecting sheet that caused adhesion problems.
3Reliability
If eye members are provided at through holes of the protector cover, then the camera lenses are protected, but the eye members may protrude from the surface and be damaged and scratched
Solution Approach 1:
The patent applies the nesting principle by placing the eye members inside recesses or cavities formed in the protector cover structure. The eye members are nested within the protector cover body rather than protruding from it, which protects them from external damage and scratches while still allowing them to perform their protective function for the camera lenses.
4Productivity
If the protector cover is made from an integral large piece of cover material sheet, then mass production is enabled, but the surface treatment must be applied to the entire large surface
Solution Approach 1:
The patent applies segmentation by dividing the surface treatment process into distinct stages: abrasive blasting of the entire large surface, followed by selective electrolytic coloring of specific areas. This allows mass production from integral sheets while managing surface treatment complexity through process segmentation rather than physical segmentation of the material.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a camera lens protector assembly that enhances the aesthetic appearance of the mobile phone, offers protection for the camera lenses, and allows for mass production with customizable colors, while maintaining the optical functionality of the cameras.
Implementation Method 1
an outer surface of a protector cover of the camera lens assembly is treated by an abrasive blasting method so as to obtain a visually clean surface and a satisfactory surface profile of the protector cover
Implementation Method 2
the outer surface of the protector cover can be formed with a desired color after an electrolytic coloring step
