Solution Overview

Problem

Conventional display devices for electronic appliances face issues with air flow restriction between the touch screen panel and the LCD panel, leading to oil film phenomena and slow removal of rainbow colors, due to narrow air communication holes and incorrect positioning of the sponge, which affects the touch screen's return to its original position.

Innovation Solution

Incorporating an intermediate member with an air passage featuring multiple paths oriented in different directions, including outer, inner, and central paths, to facilitate easy air flow between the touch screen panel and the LCD panel, and providing foreign matter accumulation parts to filter out contaminants, ensuring unobstructed air flow and rapid panel return.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If narrow air communication holes are used to connect the interior space between touch screen panel and LCD panel to the exterior, then the structure is simple and compact, but air flow is restricted causing oil film phenomena and slow panel return

Engineering Contradiction:

Improvestructure simplicityVSAvoidair flow efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The air passage is divided into multiple separate paths (first air passage and second air passage) instead of using a single narrow hole. This segmentation allows air to flow through multiple channels simultaneously, increasing overall air flow efficiency while maintaining a compact structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The air passages are configured to extend in different directions (first air passage extends in first direction, second air passage extends in second direction). This dimensional diversification of air flow paths increases the effective air flow area without increasing the overall device footprint, resolving the contradiction between structural compactness and air flow efficiency.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If sponge is positioned with inner periphery inside LCD panel periphery and outer periphery between LCD panel and touch screen panel, then the sponge can dampen impact and prevent foreign matter entry, but air flow is blocked causing slow touch screen return

Engineering Contradiction:

Improveimpact protection and foreign matter preventionVSAvoidtouch screen return speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The sponge's air blocking function is segmented by introducing multiple air passages through it. The sponge remains in place to provide impact protection and foreign matter prevention, while the air passages create dedicated channels for air flow, separating the protective function from the air flow function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The air passages act as intermediaries that allow air to pass through the sponge structure. The sponge serves as a mediator that simultaneously provides mechanical protection (impact dampening and foreign matter prevention) while permitting air flow through its internal passage structure, resolving the contradiction between protection and air flow.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If air communication holes are formed by grooves extending beyond LCD panel periphery, then air can be introduced to the interior space, but the holes are narrow causing restricted air flow and slow removal of oil film phenomenon

Engineering Contradiction:

Improveair introduction capabilityVSAvoidair flow rate

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

Instead of relying on a single air introduction path through groove-formed holes, the system segments air flow into multiple dedicated passages (first and second air passages). This segmentation increases the total effective air flow area and rate while maintaining the ease of air introduction capability.

Inventive Principle:

Principle #1Segmentation
