Solution Overview

Problem

Display apparatuses installed outdoors face challenges in maintaining waterproof and dustproof functions due to exposure to water and dust, with conventional sealing methods requiring multiple adhesive applications and leading to gaps and reduced assembly performance.

Innovation Solution

A sealing member with a bendable design that forms a closed loop with a single adhesive application, featuring a flexible material with a specific cross-sectional shape to ensure uniform sealing and improved coupling, preventing gaps at corners and enhancing assembly efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional sealing methods are used, then waterproof and dustproof functions are achieved, but multiple adhesive applications are required and assembly performance is reduced

Engineering Contradiction:
Improvewaterproof and dustproof functionVSAvoidassembly process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing member integrates multiple functions into a single component: the body portion provides sealing, the bent portion forms a closed loop structure, and adhesive is applied once to achieve both sealing and structural integrity. This eliminates the need for multiple separate adhesive applications required by conventional methods.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sealing member is divided into distinct functional portions: a body portion for primary sealing and a bent portion that extends and bends to form a closed loop. This segmentation allows each portion to perform its specific function while simplifying the overall assembly process.

Inventive Principle:
Principle #1Segmentation

2Reliability

If conventional sealing methods are used, then sealing is achieved, but gaps occur at corners and assembly efficiency is reduced

Engineering Contradiction:
Improvesealing integrityVSAvoidassembly efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The bent portion is designed to be flexible and adaptable, extending and bending to conform to corner geometries. This dynamic structure ensures continuous sealing contact at corners without gaps, while the single adhesive application maintains high assembly efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bent portion acts as a flexible sealing element that can deform to match the corner contours of the housing and housing cover, ensuring continuous sealing contact and eliminating gaps that would occur with rigid conventional methods.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If multiple adhesive applications are used, then sealing is achieved, but assembly time increases and productivity decreases

Engineering Contradiction:
Improvesealing functionVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The bent portion is pre-formed into a closed loop structure with adhesive application points positioned in advance. This preliminary preparation allows the sealing member to be installed in a single operation, eliminating the need for multiple sequential adhesive applications and reducing assembly time.

Inventive Principle:
Principle #10Preliminary action
