Solution Overview

Problem

Existing display apparatuses with M×N matrix configurations face challenges in installation and space usability due to the need for rear access to circuit parts, which complicates maintenance and increases installation time, especially when circuit parts are broken, as rear access reduces space usability and makes it difficult to identify faulty modules.

Innovation Solution

A display module design featuring a frame with magnetic coupling members that allow the circuit part and LED module to be detachably mounted and separated from the front, using a coupling protrusion with an elastic member to securely attach to the support without additional coupling members, enabling front access and reducing the risk of module damage during installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If circuit parts are mounted inside the display module for compact design, then device complexity is reduced, but ease of repair deteriorates because rear access is required for maintenance

Engineering Contradiction:

Improvestructural complexityVSAvoidcircuit part accessibility

Core Design Contradiction:

Device complexityVSEase of repair

Solution Approach 1:

The patent inverts the conventional mounting approach by allowing circuit parts to be accessed from the front of the display module rather than requiring rear access. The circuit part is detachably mounted to the bracket such that it can be separated from the front surface, reversing the traditional access direction and solving the contradiction between compact internal mounting and ease of repair.

Inventive Principle:

Principle #13The other way round (Inversion)

2Area of stationary object

If display modules are installed adjacent to walls to maximize space usability, then area of stationary object is improved, but ease of operation deteriorates due to lack of working space behind the support

Engineering Contradiction:

Improvespace usabilityVSAvoidinstallation accessibility

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The patent enables installation operations to be performed from the front side of the display module instead of requiring rear access. This inversion of access direction allows display modules to be installed adjacent to walls without needing rear working space, as all installation and maintenance operations can be completed from the front.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If additional coupling members are added to securely attach display module to support, then reliability is improved, but device complexity increases

Engineering Contradiction:

Improveattachment reliabilityVSAvoidcoupling structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the coupling function into the existing frame structure. The coupling protrusion is integrated into the frame body, eliminating the need for separate additional coupling members. This consolidation maintains secure attachment reliability while reducing device complexity by combining multiple functions into a single integrated structure.

Inventive Principle:

Principle #5Merging (Combining)

4Area of stationary object

If display modules are installed in M×N matrix form to expand display area, then area of stationary object is improved, but ease of repair deteriorates due to difficulty in identifying faulty modules from rear access

Engineering Contradiction:

Improvedisplay areaVSAvoidfault identification difficulty

Core Design Contradiction:

Area of stationary objectVSEase of repair

Solution Approach 1:

The patent enables fault identification and repair operations to be performed from the front side of the display apparatus instead of requiring rear access. By inverting the access direction, technicians can easily locate and repair faulty modules in the M×N matrix configuration from the front, solving the identification difficulty while maintaining large display area.

Inventive Principle:

Principle #13The other way round (Inversion)
