Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

It is difficult to accurately align and attach protective films to electronic devices without gaps, leading to unsightly bubbles and reduced visibility due to non-uniform contact with the display surface.

Innovation Solution

A protective film package that includes a tray with a recess for seating the electronic device, a photo-curing layer in the protective film, and a detachable photo-curing support structure to ensure precise alignment and attachment of the protective film to the device's front plate, with the support structure pressing the film's edge onto the plate during curing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a protective film is manually attached to the electronic device, then the attachment process is simple, but alignment accuracy is poor leading to gaps and bubbles

Engineering Contradiction:

Improveattachment process simplicityVSAvoidalignment accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

A tray is introduced as an intermediary tool between the protective film and the electronic device. The tray includes positioning structures that guide the protective film to the correct position on the device, enabling accurate alignment without requiring complex manual operations. The tray acts as a mediator that simplifies the attachment process while ensuring precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The positioning structures are pre-configured on the tray before the attachment process begins. These structures预先 establish the correct alignment between the protective film and the electronic device, eliminating the need for complex real-time alignment adjustments during the attachment process.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the protective film is attached without proper support structure, then the attachment process is faster, but bubbles and floats form between the film and display surface

Engineering Contradiction:

Improveattachment speedVSAvoidattachment quality

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

A support structure is introduced as an intermediary element between the protective film and the display surface. This support structure includes pressing members that apply uniform pressure to eliminate bubbles and floats during the attachment process, ensuring high attachment quality without significantly increasing process complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The support structure is positioned and configured before the protective film is fully attached. This preliminary positioning ensures that the pressing members are correctly aligned to apply pressure at the right locations, preventing bubble formation from the outset rather than requiring post-attachment correction.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If the protective film edge is not pressed to the front plate, then the attachment process is simpler, but gaps form between the film and plate reducing appearance quality

Engineering Contradiction:

Improveattachment structure complexityVSAvoidedge alignment precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

Pressing members are introduced as intermediary elements that specifically target the edge regions of the protective film. These pressing members apply localized pressure to ensure the film edges are firmly pressed against the front plate, eliminating gaps and improving appearance quality without requiring complex overall restructuring of the attachment system.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The pressing members are strategically positioned to apply pressure specifically at the edge regions of the protective film where gaps are most likely to form. This localized pressing approach ensures edge alignment precision without requiring uniform pressure across the entire film surface, thereby simplifying the overall attachment structure.

Inventive Principle:

Principle #3Local quality
