Privacy Filter Foam Pad Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional privacy filters for displays are difficult to attach and detach, often leaving adhesive residue and lacking shock absorption, which complicates maintenance and protection of the device.
Innovation Solution
A privacy filter with a foam pad made of polyethylene, polystyrene, or polyurethane, featuring a micro-louver structure and coatings for easy attachment and detachment, and providing shock absorption by using a micropore layer for adhesion without additional adhesives, ensuring a clean appearance and protection against external shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hang tab or double-sided tape is used to mount the privacy filter, then the privacy filter can be attached to the display, but the attachment/detachment operation becomes complicated and adhesive residue remains on the surface
Solution Approach 1:
The patent extracts the adhesive function from separate mounting mechanisms (hang tabs, double-sided tapes) and integrates it into the privacy filter structure itself through the foam pad with micropore layer, enabling direct attachment without external adhesive components
Solution Approach 2:
The patent combines multiple functions into the foam pad component: attachment (via micropore adhesion), shock absorption (via foam structure), and cushioning (via predetermined thickness), eliminating the need for separate mounting mechanisms
2Ease of operation
If a magnetic force scheme is used to fix the privacy filter, then simple attachment/detachment operation is available, but the manufacturing method becomes complicated and shock may be applied to the device due to hard magnet portion
Solution Approach 1:
The patent replaces the magnetic attachment system with a foam pad-based adhesion system that uses micropore surface contact for attachment, eliminating hard magnet portions and their associated manufacturing complexity while maintaining simple attachment/detachment operation
Solution Approach 2:
The patent uses a foam pad with micropore layer that attaches through surface adhesion via its porous structure, providing a manufacturing-friendly alternative to magnetic systems while achieving the desired attachment functionality
3Reliability
If conventional mounting mechanisms or adhesives are used, then the privacy filter can be secured to the display, but adhesive residue remains on the surface compromising the clean appearance
Solution Approach 1:
The patent extracts the adhesive function from external mounting mechanisms and embeds it within the foam pad structure, where the micropore layer provides adhesion without leaving visible residue on the display surface
Solution Approach 2:
The foam pad acts as an intermediary between the privacy filter and display surface, providing attachment functionality through its micropore structure while preventing direct contact between adhesives and the display, thus avoiding residue contamination
4Device complexity
If the privacy filter lacks shock absorption function, then the structure remains simple, but the display is vulnerable to external shock and damage during folding or impacts
Solution Approach 1:
The patent incorporates a foam pad with predetermined thickness between the privacy filter and display surface, providing pre-positioned shock absorption and cushioning capabilities that protect the display from external impacts and folding stresses before damage can occur
Solution Approach 2:
The patent uses a composite structure combining the privacy filter film with a foam pad material, creating a multi-layer assembly that provides both the privacy filtering function and shock absorption protection through the foam's energy-dissipating properties
