Solution Overview

Problem

Existing display apparatuses face challenges in achieving a slim and compact appearance with reduced bezel and manufacturing costs, as they often require complex assembly processes and materials that increase thickness and material costs.

Innovation Solution

A display apparatus design featuring a liquid crystal display (LCD) panel with a front cover, a guide panel coupled to the front cover, and a back cover, utilizing latches and a unique coupling mechanism to reduce thickness and bezel while simplifying manufacturing processes and reducing material usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex assembly processes and materials are used, then assembly strength and reliability are improved, but thickness and manufacturing costs increase

Engineering Contradiction:
Improveassembly strengthVSAvoidthickness
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The front cover is divided into multiple segments with individual latch mechanisms (first latches and second latches) that can be independently engaged with the back cover and guide panel. This segmentation allows for a thinner overall structure while maintaining assembly strength through distributed connection points rather than requiring thick reinforcing elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The latch mechanisms are nested within the front cover structure, with the first latches and second latches integrated into the cover body. This nesting eliminates the need for separate external fastening components, reducing overall thickness while maintaining reliable assembly through the integrated latch system.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If complex assembly processes and materials are used, then assembly strength and reliability are improved, but manufacturing costs increase

Engineering Contradiction:
Improveassembly strengthVSAvoidmanufacturing costs
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Multiple fastening functions are merged into a single front cover component. The first latches engage with the back cover while the second latches engage with the guide panel, combining what would traditionally require separate fastening mechanisms into one integrated part. This reduces manufacturing complexity and cost while maintaining assembly strength.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The front cover serves multiple functions simultaneously: it provides structural support, houses the latch mechanisms for securing to both the back cover and guide panel, and maintains the sealed enclosure. This multi-functionality eliminates the need for separate components, reducing manufacturing costs while ensuring reliable assembly.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If traditional coupling mechanisms are used, then assembly stability is improved, but bezel width and thickness increase

Engineering Contradiction:
Improveassembly stabilityVSAvoidbezel width
Core Design Contradiction:
Stability of the object's compositionVSLength of moving object

Solution Approach 1:

The latch mechanisms engage in multiple dimensions: the first latches provide vertical engagement with the back cover while the second latches provide horizontal engagement with the guide panel. This multi-dimensional coupling achieves assembly stability without requiring increased bezel width, as the stability is achieved through spatial distribution of engagement points rather than through increased material thickness.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
