Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display systems require different sizes to accommodate varying pitches for desired resolutions, leading to the need for multiple cabinet and mounting structures, increasing costs and complexity.
Innovation Solution
Modular LED display panels of the same size and shape with different pixel pitches can be combined to form integrated systems, allowing for flexible configuration and expansion without the need for multiple cabinet sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different sized LED display panels are used to accommodate varying pitches for desired resolutions, then the display resolution and image quality are improved, but the device complexity and inventory costs increase due to the need for multiple cabinet and mounting structure sizes
Solution Approach 1:
The patent applies universality by designing a single standardized cabinet and mounting structure that can accommodate LED display panels with different pitches and resolutions. The universal mounting structure includes adjustable components and standardized interfaces that allow different panel types to be mounted using the same hardware platform, eliminating the need for multiple specialized cabinet sizes and reducing inventory complexity while maintaining the ability to achieve various display resolutions
Solution Approach 2:
The patent applies segmentation by dividing the mounting structure into modular, standardized components that can be configured for different panel types. The cabinet structure is segmented into standardized frames, mounting brackets, and support elements that can be assembled in different configurations to accommodate various panel pitches, allowing the system to handle multiple resolutions through modular assembly rather than requiring completely different cabinet designs
2Measurement precision
If different sized LED display panels are manufactured to accommodate varying pitches, then the desired resolution is achieved, but the manufacturing costs and installation complexity increase
Solution Approach 1:
The patent applies universality in manufacturing by establishing a single standardized production line and cabinet design that can manufacture and accommodate panels with different pitches. The standardized cabinet design with universal mounting interfaces allows the same manufacturing processes and assembly procedures to be used regardless of the specific panel pitch, simplifying the manufacturing process and reducing the skill level required for installation while maintaining the ability to produce various resolutions
3Adaptability or versatility
If multiple cabinet sizes are maintained in inventory to support different display resolutions, then various resolution requirements are met, but the inventory costs and storage requirements increase
Solution Approach 1:
The patent applies universality by maintaining inventory of only a single cabinet and mounting structure type that can be configured to support multiple display resolutions through its standardized, adjustable components. This universal design allows the same cabinet units to be reused across different applications with varying resolution requirements, dramatically reducing inventory stock and storage requirements while maintaining the ability to meet diverse display resolution needs through software configuration and panel selection

AI summary
An embodiment modular light-emitting diode (LED) display panel includes attachment points for use in attachment as part of a multi-panel modular LED display, a printed circuit board including a first side and an opposite second side, and a plastic casing attached to the opposite second side of the printed circuit board. A perimeter of the plastic casing is substantially rectangular and has a height and a width. The modular LED display panel further includes a display surface including a plurality of LEDs arranged as pixels and attached to the first side of the printed circuit board. The pixels are arranged in a rectangular array including at least fifty pixels. Each of the pixels of the rectangular array is spaced from each respective adjacent pixel of the rectangular array by a pitch. The pitch is a predetermined constant number. The pitch does not depend on the height and the width.
