Security Label with Bend-Induced Trace for Lens Cover

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current security measures for image photographing devices like mobile phones and digital cameras are inadequate in preventing unauthorized photography, especially in restricted areas, as they can be easily bypassed or muted, and existing labels leave adhesive residue, making them impractical.

Innovation Solution

A security label with a transparent film, patterned release layer, and cushion layer that bends upon removal, creating a visible trace when reapplied, ensuring the label's removal is evident, and a non-adhesive area to protect the lens, preventing photography and maintaining device cleanliness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional manipulation prevention label is removed from a surface, then the label can be removed, but adhesive layer remains on the surface and traces remain on both the label and surface

Engineering Contradiction:

Improvelabel removalVSAvoidadhesive residue and traces

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The adhesive layer is extracted and separated from the label body, allowing the label to be removed cleanly without leaving adhesive residue on the surface. The label body itself becomes the removable component while the adhesive remains on the label after removal.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of the adhesive remaining on the surface after label removal, the invention inverts this by designing the system so that the adhesive remains on the label body after removal, leaving the surface clean and trace-free.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If a security label is applied to cover the lens part to prevent photography, then photography is prevented, but the label cannot be easily removed and reapplied

Engineering Contradiction:

Improvephotography preventionVSAvoidlabel removal and reapplication

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The label is designed with dynamic properties allowing it to be easily applied and removed multiple times. The label body can be peeled off and reapplied to the lens part, maintaining its security function through multiple cycles of application and removal.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The label is pre-designed with the understanding that it will be removed and reapplied. The structure anticipates this preliminary action by ensuring the label maintains its integrity and security function after removal and reapplication.

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If the label body is bent upon removal to bring the release layer away from the transparent film, then a visible trace is created, but the label structure becomes more complex

Engineering Contradiction:

Improveremoval trace visibilityVSAvoidlabel structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The label utilizes optical property changes (transparency/opacity) rather than color changes. When the label body is bent upon removal, the release layer separates from the transparent film, creating a visible trace through changes in light transmission and refraction patterns.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The invention adds a temporal dimension to the label's appearance. The label looks normal when applied but reveals its removal status when bent, creating a trace that appears in a different state (bent vs. flat) rather than requiring additional structural complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

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

Effectively prevents unauthorized photography by leaving a visible trace of removal, ensuring accountability and protecting the lens from damage, while ensuring the device remains clean and functional.

Implementation Method 1

the cushion layer may have a contraction stress which shrinks under a solidified condition, so that the release layer and an area of the print layer corresponding to the release layer may be drawn into the cushion layer

Methodology Applied

Scientific EffectContraction stress: Thermal Contraction

AI summary

A security label 1 according to the present invention can be removably applied on an image photographing device such as a mobile phone 2 incorporating therein a digital camera to cover a lens part 3 thereof. Upon removal, the security label 1 is bent and makes a trace emerge which shows that the security label 1 has been removed. By applying the security label 1 to the mobile phone 2 to cover the lens part 3 thereof, improper photography can be prevented. In a case where the security label 1 is removed to take a photograph, the trace remains on the security label 1 even if the security label 1 is applied again on the mobile phone 2 to cover the lens part 3 thereof. Thus, the fact that a photograph is improperly taken can be easily understood.
