Modular Display Module Assembly for Front-Service Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in providing convenient service and maintenance, particularly in accessing and servicing the control board and power supply units.
Innovation Solution
The display device is designed with a modular structure, allowing for easy separation of the front display assembly from the unit frame, which enables simple access to the control board and power supply units. This is achieved through a system of connectors, magnets, and adjustment screws that allow for precise positioning and alignment of the display panels and modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the display device uses a modular structure with detachable front display assembly, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The display device is divided into modular components: a front display assembly that can be detached from the unit frame, and a rear section containing the control board and power supply. This segmentation allows service personnel to access and repair internal components without disassembling the entire device, improving ease of repair while maintaining a manageable structural complexity through standardized modular interfaces.
2Ease of repair
If the control board and power supply are positioned behind the inner plate, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The control board and power supply are extracted from the traditional integrated layout and positioned in a dedicated rear section behind the inner plate. This extraction creates a clear separation between the display front assembly and the electronic components, allowing service personnel to access and replace the control board and power supply independently. The standardized interfaces and modular design minimize the increase in structural complexity while maximizing repair accessibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular design facilitates easy maintenance and service by allowing the control board and power supply units to be accessed without disassembling the entire display device. This reduces service time and improves overall convenience, while also allowing for precise adjustment of the display panels to minimize bezel formation and ensure seamless integration of multiple modules.
Implementation Method 1
a magnet disposed on the front surface of the unit frame; and an adjustment screw screwed to the front display assembly and attachable to the magnet by magnetic force

AI summary
The display device includes a plurality of display modules arranged in an up and down direction and in a left and right direction, and the display module includes a unit frame; an inner plate coupled to the unit frame and having an inner opening; a control board disposed behind the inner plate and having a rear connector on the front surface; a back cover covering the control board; and a front display assembly disposed in front of the unit frame. The front display assembly may include at least one display panel, and a rear connector and a detachable front connector may be disposed. At least one of the rear connector and the front connector may pass through the inner opening.
