Privacy Screen Filter with Magnetic Mounting and Camera Slide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing privacy screen filters for computers, particularly laptops and tablets, are not secure against camera misuse and often rely on adhesive mounting methods that leave marks, are aesthetically unattractive, and prone to falling off over time.
Innovation Solution
A privacy screen filter with reinforcing plate-shaped elements and a movable slide that allows for secure camera coverage, along with hook or magnetic mounting systems that provide stable and adhesive-free attachment, ensuring easy installation and removal without damaging the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive mounting methods are used for privacy screen filters, then the filter can be easily mounted on the screen, but it leaves marks and glue remains on the screen edge when removed
Solution Approach 1:
The patent replaces adhesive mounting with a mechanical mounting system using holding elements that engage with recesses in the screen frame. This substitution eliminates the need for glue while providing secure attachment, resolving the contradiction between ease of mounting and avoidance of residue.
Solution Approach 2:
The patent introduces holding elements and recesses as intermediary mechanical features between the screen filter and the screen frame. These intermediaries enable secure mounting without direct adhesive contact with the screen surface, preventing glue residue while maintaining easy installation.
2Ease of manufacture
If adhesive mounting methods are used for privacy screen filters, then the filter can be mounted on the screen, but it is aesthetically unattractive and prone to falling off after some time
Solution Approach 1:
The patent replaces unreliable adhesive bonding with a reliable mechanical interlocking system. The holding elements engage with recesses in the screen frame, providing secure attachment that prevents the filter from falling off while remaining aesthetically pleasing.
3Object-affected harmful factors
If the screen filter covers the camera area, then privacy is protected, but the camera and sensor functionality is blocked
Solution Approach 1:
The patent segments the screen filter into multiple parts: an opaque privacy portion that blocks the camera area, and a transparent window portion that allows camera and sensor functionality. This segmentation enables the filter to simultaneously provide privacy protection and maintain camera usability.
Solution Approach 2:
The patent applies different optical properties to different areas of the screen filter. The area corresponding to the display receives privacy protection while the area corresponding to the camera and sensors remains transparent, allowing each region to have the quality needed for its specific function.
4Reliability
If a secure mounting system is implemented, then the filter remains stable on the screen, but it becomes difficult to remove and store when not in use
Solution Approach 1:
The patent creates a dynamic mounting system where the holding elements can easily transition between engaged and disengaged states. The mechanical interlocking provides stable attachment during use but allows simple removal by releasing the engagement, enabling easy storage when not in use.

AI summary
A privacy screen filter (1) for mounting on computer screens (2), e.g. laptops and/or tablet pcs. The screen filter (1) includes a filter element (3) in the form of a film sheet and one or more mounting means for releasable fastening of the screen filter (1) along at least one edge of the screen. The mounting means include one or more magnets or hook elements (5) disposed along the upper edge of the film sheet for fastening to the upper edge of the computer screen. The screen filter (1) also includes reinforcing plate-shaped elements (9, 10) along the upper edge and possibly also along the lower edge (15, 16) of the film sheet (3). An aperture (11) in the reinforcing plate- shaped elements (9, 10) allow use of a camera, and the aperture has a slide (12) for covering the aperture. The privacy screen filter (1) is easy to mount and subsequently dismount, is durable and aesthetic, not leaving any visible fastening means on the computer screen (2) when the screen filter (1) is not in use.
