Display Protective Sheet Cutout for Easy Removal Without Tabs

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Protective sheets with tabs on display devices can deform or detach when removed, causing inconvenience and reducing user-friendliness due to potential contact with the user's body or external members.

Innovation Solution

A protective sheet for display devices is designed with a cutout inward from the outer edge, allowing easy removal without protruding beyond the device's edge, using a tool or fingernail through the cutout to facilitate detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the protective sheet includes a tab for easy removal, then ease of operation is improved, but the protective sheet may deform or detach unintentionally when contacting the user's body or external members

Engineering Contradiction:

Improveease of removalVSAvoidstability of protective sheet

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The protective sheet is segmented by forming a cutout that divides the sheet into distinct regions. This segmentation creates a removal portion that can be easily grasped and pulled without requiring a protruding tab, thus maintaining ease of removal while preventing unintended deformation or detachment during normal use.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A removal portion is extracted from the protective sheet by forming a cutout that extends from the outer edge toward the center. This extracted portion can be easily grasped and pulled for removal, providing ease of operation without needing a protruding tab that could cause unintended detachment.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If the protective sheet has a tab protruding beyond the edge, then ease of removal is improved, but the appearance quality and adhesion are compromised

Engineering Contradiction:

Improveease of removalVSAvoidappearance quality

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The protective sheet is segmented by forming a cutout that creates a removal portion within the sheet's boundary. This segmentation allows the removal portion to be grasped and pulled without requiring any part of the protective sheet to protrude beyond the display device's edge, thus maintaining appearance quality while enabling easy removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of creating a protruding tab that extends beyond the sheet's plane, the solution uses a cutout that creates a removal portion within the sheet's plane. This dimensional approach allows easy grasping and removal without compromising the flat, clean appearance of the protective sheet's outer edge.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A display device includes: a display module that has a flat surface rectangular in shape and that displays information on a display area within the flat surface; and a protective sheet affixed to the flat surface. An outer edge of the protective sheet is positioned, as viewed from a direction orthogonal to the flat surface, on an outer edge of the flat surface or inward of the outer edge of the flat surface. The protective sheet has a cutout having been formed therein by cutting the protective sheet inward from the outer edge of the protective sheet as viewed from the direction orthogonal to the flat surface.
