Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic display boards with removable panels face challenges in maintenance, misalignment, and environmental protection, leading to image distortion and component damage.
Innovation Solution
A modular design with removable panels that can be attached and removed from both the front and rear, featuring apertures for precise LED placement and coupling devices for easy alignment and protection from environmental elements, along with horizontal fins for shading and heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If smaller removable panels are used to facilitate maintenance, then ease of repair is improved, but manufacturing precision deteriorates due to misalignment between panels causing image distortion
Solution Approach 1:
The display board is divided into multiple smaller removable panels that can be independently accessed and serviced from the rear, facilitating maintenance while maintaining overall image integrity through precise alignment features
Solution Approach 2:
Alignment features such as guide rails, positioning pins, or magnetic alignment mechanisms serve as intermediaries between adjacent panels to ensure precise positioning and minimize image distortion during assembly and disassembly
2Ease of repair
If removable panels are used to improve maintenance accessibility, then ease of repair is improved, but reliability deteriorates due to joints exposing electronic components to environmental factors
Solution Approach 1:
Sealing gaskets, weatherstripping, or protective films are applied at the joints between removable panels to create protective barriers that shield electronic components from environmental factors while allowing for panel removal and reinstallation
Solution Approach 2:
One panel is designed to nest within or overlap with adjacent panels, creating a layered structure where the joint areas are protected by the overlapping portions, reducing direct exposure to environmental elements
3Ease of operation
If coupling devices are made easily operable from front and rear, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The coupling device is designed with universal functionality, incorporating features such as dual-sided access mechanisms, integrated alignment and fastening functions, and standardized interfaces that can be operated from either the front or rear of the panel, reducing the need for separate mechanisms for each operation

AI summary
Display apparatus and methods of making them are disclosed. The display apparatus includes frame members assembled to form a frame for the display apparatus and display modules configured for displaying at least a portion of an adaptable image. Each display module is coupled to the frame members to form a matrix organization of display modules for the display apparatus. The display module includes a removable panel and apertures formed therethrough. The apertures are arranged as pixel rows including pixel arrangements distributed along each pixel row. The display module also includes coupling devices attached to the removable panel, which are configured for detachably coupling the removable panel to the frame members, wherein the coupling devices may be operated to attach or remove the removable panel. Furthermore, the coupling devices are configured such that they can be operated from a front side or from a back side of the removable panel.
