Solution Overview

Problem

Existing display frame structures face challenges in achieving a narrow frame design while maintaining strength and maximizing active display area, as a narrow frame design results in a weak structure and reduced active area due to excessive occlusion by the front frame.

Innovation Solution

A display frame structure comprising a rear housing with a side frame that forms a recess to accommodate the display module, eliminating the need for a separate front frame and incorporating a strengthening frame with ribs for enhanced support, allowing for a narrow frame design without compromising strength and increasing the active display area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the distance L between the inner edge and outer edge of the front frame is designed to be relatively large to obtain high strength for the side of the display module, then the strength of the display module side is improved, but the active area of the display is reduced and the frame becomes wide

Engineering Contradiction:

Improvestrength of display module sideVSAvoidactive area of display

Core Design Contradiction:

StrengthVSArea of moving object

Solution Approach 1:

The patent removes the traditional front frame structure that caused occlusion of the display area. Instead, the display module's side is directly integrated with the rear housing, extracting the problematic front frame element while maintaining structural strength through direct integration and positioning features.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the functions of the front frame and rear housing by directly integrating the display module side with the rear housing. The positioning features and fixing structures combine the support and positioning functions that were previously distributed across separate front frame and rear housing components.

Inventive Principle:

Principle #5Merging (Combining)

2Area of moving object

If the distance L between the inner edge and outer edge of the front frame is designed to be smaller to achieve narrow frame design, then the active area of the display is increased, but the strength of the display frame structure becomes weak and the structure is easy to be deformed

Engineering Contradiction:

Improveactive area of displayVSAvoidstrength of display frame structure

Core Design Contradiction:

Area of moving objectVSStrength

Solution Approach 1:

The patent applies local quality by adding positioning features and fixing structures at specific locations where strength is needed. Rather than increasing the overall frame distance L, localized reinforcement elements are introduced at critical points to maintain structural integrity while preserving the narrow frame design.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent employs composite construction by integrating multiple functional elements (positioning features, fixing structures, reinforcing ribs) into the rear housing and display module assembly. This creates a composite structure that achieves both narrow frame dimensions and high structural strength through the synergistic combination of different structural components.

Inventive Principle:

Principle #40Composite materials

3Strength

If a separate front frame is used to maintain structural strength, then the strength of the display frame structure is improved, but the device complexity increases and the frame width increases

Engineering Contradiction:

Improvestrength of display frame structureVSAvoiddevice complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent merges the front frame function into the rear housing structure by directly integrating the display module side with the rear housing. This eliminates the need for a separate front frame component, reducing device complexity while maintaining structural strength through the integrated design and associated positioning features.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The rear housing is designed to perform multiple functions: it serves as both the structural housing and the positioning/fixing structure for the display module. The positioning features and fixing structures integrated into the rear housing provide both structural support and module fixation, eliminating the need for separate front frame components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A display frame structure and a display device belonging to the field of display technology. The structure may alleviate and/or mitigate the problem for the existing display frame structure and display device that the strength will become weak in case of narrow frame design and the active area is reduced. The display frame structure of the embodiment has a side frame formed integrally with the rear housing or detachably connected to the rear housing, the side frame and the plane of the rear housing may form a recess, which may be used for accommodating the display module. The side frame may wrap a side of the display module. Therefore, a fixing structure for this side of the display module is not required, the design for the front frame may be omitted, and a narrow frame design for the display device may be achieved.
