Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The variability in dimensions of display modules from different manufacturers leads to increased manufacturing costs and prolonged development periods due to the need for multiple rear frame designs and molds in display devices.

Innovation Solution

A position-limiting mechanism, comprising a supporting portion, an elastic portion, and an abutting portion, is integrated into the rear frame to securely fix display modules of varying sizes, allowing a single frame design to accommodate different module dimensions by generating counteracting forces and preventing excessive deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional rear frame with fixed ribs is used to secure display modules, then the display module positioning is stable, but multiple frame designs and molds are required when display module dimensions vary across manufacturers

Engineering Contradiction:

Improvedisplay module positioning stabilityVSAvoidcompatibility with different display module dimensions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the fixed, rigid rib structure into a dynamic elastic portion that can deform and adapt to different display module dimensions. The elastic portion includes a supporting portion, an elastic portion, and an abutting portion that work together to provide flexible positioning, allowing the same frame design to accommodate various module sizes while maintaining secure fixation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the physical state of the positioning structure from rigid to elastic. The elastic portion can be made of rubber or elastic resin, allowing it to deform under compression and adapt to dimensional variations in display modules from different manufacturers, thus providing universal compatibility without requiring multiple frame designs

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple rear frame designs are created to accommodate different display module dimensions, then compatibility with various manufacturers' modules is improved, but manufacturing cost and development time increase

Engineering Contradiction:

Improvecompatibility with different display module dimensionsVSAvoidmanufacturing cost and development time

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent creates a universal frame design where the elastic portion serves multiple functions: it provides positioning, allows dimensional adaptation, and secures modules of varying sizes. This single design can accommodate display modules from different manufacturers with different dimensions, eliminating the need for multiple specialized frame designs and reducing manufacturing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the elastic portion is made highly resilient to accommodate size variations, then adaptability to different display modules is improved, but the risk of excessive deformation and breakage increases

Engineering Contradiction:

Improveaccommodation of varying display module sizesVSAvoidelastic portion durability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies different structural characteristics to different parts of the elastic portion. The supporting portion provides structural support, the elastic portion provides flexibility and deformation capability, and the abutting portion provides positioning function. This localized differentiation allows each part to optimize its function while working together to prevent excessive deformation and improve overall durability

Inventive Principle:

Principle #3Local quality

AI summary

A frame includes a main body, a sidewall extending substantially from an edge of the main body, and a position-limiting mechanism disposed at an inner surface of the sidewall. The position-limiting mechanism includes an elastic portion, an abutting portion extending from the elastic portion, and a stopping portion extending from the abutting portion. A gap is defined between the inner surface of the sidewall and the stopping portion when the elastic portion is in a relaxed state. A display device employing a frame is also provided.
