Solution Overview

Problem

Existing display devices face challenges in enhancing reliability, particularly in withstanding external impacts without deformation or damage to the display panel.

Innovation Solution

The display device incorporates a protection member that covers the edges of the display panel and an impact alleviation member made of ink with specific elastic properties, which is applied between the edges and the protection member to absorb external impacts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a protection member is added to cover the edges of the display panel, then the display device's ability to withstand external impacts is improved, but the device complexity increases

Engineering Contradiction:
Improveimpact resistanceVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The impact alleviation member is applied in advance to the edges of the display panel before the protection member is attached. This preliminary application ensures that when external impact occurs, the ink-based member is already in position to absorb and distribute the impact force, preventing deformation of the display panel without requiring complex real-time response mechanisms

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The ink-based impact alleviation member serves as an intermediary element between the external impact source and the display panel edges. It mediates the impact force by absorbing and distributing it across the edges, preventing direct transmission of harmful forces to the fragile display panel structure

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If an impact alleviation member made of ink is applied to the edges, then the display panel is protected from deformation, but the manufacturing process complexity increases

Engineering Contradiction:
Improveedge protectionVSAvoidmanufacturing process simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces traditional mechanical protection methods (such as rigid borders or metal frames) with an ink-based material that cures to form a protective layer. This substitution allows for simpler application processes similar to standard printing or coating techniques, reducing manufacturing complexity while maintaining effective impact protection

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The ink material undergoes a parameter change from liquid state during application to solid state after curing. This phase transition enables the material to be easily applied using simple coating or printing methods, then transforms into a rigid protective layer that effectively resists impact forces, simplifying the overall manufacturing process

Inventive Principle:
Principle #35Parameter changes
