Solution Overview

Problem

Conventional LED display screens face difficulties in maintenance and module replacement due to small spacing between light sources, making it challenging to accommodate traditional connecting members like screws, and existing designs are not suitable for small spacing displays.

Innovation Solution

The solution involves a small-spacing pre-maintenance LED display screen design with magnetic elements and a movable connecting rod system, allowing for easy connection and disconnection of LED modules without the need for screws, enabling infinite expansion of the display screen while reducing maintenance complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional connecting members such as screws are used to fix LED modules, then the LED modules can be firmly fixed on the frame, but the later maintenance and replacing of the modules will be difficult

Engineering Contradiction:
Improvefixing strengthVSAvoidmaintenance difficulty
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The patent replaces the conventional mechanical screw connection system with a magnetic connection system. The frame is equipped with magnetic elements that attract and hold the LED modules, allowing for easy attachment and detachment without tools. This substitution maintains firm fixing strength while dramatically improving ease of maintenance and replacement.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If the spacing of light source on LED modules is reduced to improve resolving power, then the display quality is improved, but there is no space for arrangement of the connecting members

Engineering Contradiction:
Improveresolving powerVSAvoidconnecting member arrangement
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

By replacing mechanical connecting members (screws, clips) with magnetic elements, the patent eliminates the need for physical connection structures on the LED modules themselves. The magnetic field extends through space, allowing connection without occupying physical space on the densely packed module surface, thus enabling small spacing while maintaining connectivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic connection system transitions from a two-dimensional surface connection (requiring space on the module face) to a three-dimensional field-based connection. The magnetic field penetrates through the small spacing between light sources, establishing connection in the spatial dimension rather than requiring surface dimension, thus resolving the space constraint.

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

3Stability of the object's composition

If LED modules are firmly fixed using conventional methods, then the display screen structure is stable, but the modules cannot be easily removed for maintenance

Engineering Contradiction:
Improvestructural stabilityVSAvoidmodule removal ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The magnetic connection system provides dynamic characteristics - strong holding force during operation ensures structural stability, while the ability to easily overcome the magnetic force with simple pulling motion enables easy removal for maintenance. The system adapts between these two states without requiring different connection mechanisms.

Inventive Principle:
Principle #15Dynamics

Function Achieved in This Case

This design facilitates efficient assembly, maintenance, and expansion of LED display screens by allowing workers to connect and disconnect modules from the front, reducing floor space and improving maintenance efficiency, and allows for smaller spacing between light sources without compromising connectivity.

Implementation Method 1

The box is provided with plurality of box magnetic elements. Each LED module is provided with module magnetic elements on the back. The plurality of LED modules are magnetized on the front face of the box by the box magnetic elements and module magnetic elements corresponding to each other.

Methodology Applied
Scientific EffectMagnetic suction: Magnetism

Implementation Method 2

Each LED modules is provided with detachment magnetic elements corresponding to magnetic detachment assistors producing magnetic suction to the elements. Worker uses the magnetic detachment assistors by hand to get close to the corresponding LED modules, then, the LED modules and the assistors are connected together by the magnetic suction acted on the detachment magnetic elements by the assistors. At the same time, the worker applies a external pull force on the magnetic detachment assistors, and this force can overcomes the magnetic suction acted on the module magnetic unit by the box magnetic unit, furthermore, the connecting between the magnetic units and is broken, so the LED modules can be removed from the box.

Methodology Applied
Scientific EffectMagnetic suction: Magnetism

Implementation Method 3

The display connecting unit is a movable connecting rod. The connecting ends are arranged respectively on the two ends of the rod. When the movable connecting rod moves, the connecting ends provided on the two ends of the rod move simultaneously, therefore, any two adjacent boxes are connected together.
