Solution Overview
Problem
Existing LED display devices face challenges with high weight, high cost, and reduced assembly efficiency due to heavy box bodies and accumulative assembly errors, which affect precision and attractiveness of the display.
Innovation Solution
The implementation of a hanging-type or seat-type transverse fixed beam assembly structure that connects unit display modules magnetically to a rear frame assembly, sharing power and signal connections, and utilizing a fine adjustment mechanism to reduce errors and enhance assembly precision, with a power supply system that converts high voltage to 5V direct current for efficient power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each single box body is provided with a power supply, then the box body can operate independently, but the box body becomes heavy and the cost increases
Solution Approach 1:
The patent consolidates power supply resources by sharing a common power distribution system through transverse fixed beams. Multiple box bodies connect to shared power inputs located on the rear frame, eliminating the need for independent power supplies in each box body. This merging approach reduces overall weight while maintaining operational reliability through centralized power management.
Solution Approach 2:
The transverse fixed beam structure serves multiple functions: it provides mechanical support, enables power distribution to multiple units, and facilitates signal transmission. This multi-functional design allows a single structural element to replace what would otherwise require separate components in each box body, reducing weight and complexity.
2Ease of manufacture
If traditional assembling methods are used with box body frames, then the display can be constructed, but accumulative errors between display modules and box bodies become larger
Solution Approach 1:
The patent replaces traditional mechanical fastening systems with magnetic attraction mechanisms. The rear frame assembly incorporates magnetic components that automatically align and secure display modules without requiring precise mechanical drilling and fastening. This substitution eliminates accumulative assembly errors while maintaining ease of construction through simple magnetic attachment.
3Ease of manufacture
If a fixing structure is used to fasten box bodies, then the display screen can be assembled, but wire rods are exposed so that attractiveness is influenced
Solution Approach 1:
The patent integrates the fixing mechanism with the structural frame by incorporating magnetic fixing components directly into the rear frame assembly. This merging eliminates the need for separate external fixing structures that would expose wire rods, as the magnetic attachment occurs within the enclosed frame structure, maintaining both assembly ease and aesthetic appearance.
4Manufacturing precision
If installation surface machining precision reaches the limit, then further precision improvement becomes difficult, but the splicing method cannot meet pre-maintenance and high precision requirements simultaneously
Solution Approach 1:
The patent divides the display system into modular box bodies that can be independently maintained and replaced. The magnetic attachment mechanism allows individual modules to be quickly detached and serviced without affecting other units, enabling pre-maintenance capabilities while maintaining high overall precision through standardized modular interfaces.
Solution Approach 2:
The magnetic fixing system provides dynamic adjustment capability, allowing display modules to be easily positioned and repositioned during assembly and maintenance. This dynamic characteristic enables high precision alignment to be achieved and adjusted as needed, while also facilitating quick maintenance operations without permanent fixed connections.
