Solution Overview

Problem

Existing display panels require maintenance from either the front or the back, limiting user flexibility and affecting user experience.

Innovation Solution

A display panel design with a cabinet that allows maintenance from both the front and the back, featuring display module openings, a power supply assembly opening, and a protective cover plate, along with worm gear locks for seamless splicing and easy access to components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display panel uses a traditional single-sided maintenance structure, then the structure is simple, but the user cannot access both front and rear components simultaneously, reducing maintenance flexibility

Engineering Contradiction:
Improvemaintenance flexibilityVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cabinet is divided into distinct functional zones: a front maintenance area with a first cabinet body for accessing display modules from the front, and a rear maintenance area with a second cabinet body for accessing power supply assemblies from the back. This segmentation allows simultaneous access to different components from opposite sides, resolving the contradiction between maintenance flexibility and structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The maintenance structure transitions from a single-sided (one-dimensional access) design to a dual-sided (two-dimensional access) design. By adding rear access openings and a second cabinet body, the system enables maintenance personnel to work from both front and rear directions simultaneously, effectively adding another dimension to the maintenance approach without excessive structural complexity.

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

2Adaptability or versatility

If the display panel allows simultaneous front and rear maintenance access, then user experience is improved, but the structural complexity increases

Engineering Contradiction:
Improvemaintenance access versatilityVSAvoidcabinet structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cabinet structure is designed with multi-functionality: the front cabinet body handles display module maintenance, while the rear cabinet body handles power supply assembly maintenance. Both cabinet bodies share similar structural features (openings, protective covers, mounting structures), allowing the same design pattern to serve multiple maintenance functions, thereby increasing versatility without proportionally increasing overall complexity.

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

AI summary

Disclosed are a display panel (1) and a display screen. The display panel (1) includes a plurality of display modules (100) and a cabinet. The plurality of display modules (100) are distributed in a matrix and are fixed in front of the cabinet. The cabinet is provided with two display module openings (210) and a power supply assembly opening (220). A protective cover plate is installed in front of the cabinet to cover the power supply assembly opening (220) and form a power supply assembly cavity behind the cabinet, which is configured to install a power supply assembly (400). Two module opening cover plates (320) are installed behind the cabinet to cover the two display module openings (210) in a one-to-one correspondence.
