LED Display Locking Knob for Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED displays for sports applications are time-consuming to assemble, disassemble, and maintain due to fixed screw-based modules and potential mis-assembly issues between left, right, upper, and lower portions.
Innovation Solution
An LED display design featuring a locking knob that allows for quick connection between the casing frame and LED module without accessory tools, utilizing a spiral spring wire core and magnet-chuck system for secure attachment, along with a uniform module specification to prevent mis-assembly, and a backup power and receiver system for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw fastening methods are used to fix LED modules, then the connection stability is ensured, but the assembly and disassembly time is significantly increased
Solution Approach 1:
The fastening system is segmented into a locking knob assembly and a screw assembly that can independently function. The locking knob provides quick initial fixation while the screw provides final secure fastening, allowing selective use based on whether speed or maximum stability is prioritized
Solution Approach 2:
The locking knob acts as an intermediary component between the hand-operated quick-release mechanism and the screw-based secure fastening system. It translates rotational motion into clamping force while maintaining the connection structure integrity
2Adaptability or versatility
If LED modules with directional distinctions (left, right, upper, lower portions) are used, then the display can be configured for specific positions, but the risk of mis-assembly increases and maintenance time is extended
Solution Approach 1:
The locking knob assembly incorporates asymmetric features including a positioning post that fits into a corresponding positioning hole, ensuring that modules can only be installed in the correct orientation. This asymmetric design prevents mis-assembly while maintaining position-specific configuration capabilities
Solution Approach 2:
The positioning post and positioning hole are pre-configured on the module housing before assembly, providing automatic orientation guidance during installation. This preliminary positioning action prevents incorrect installation before the locking mechanism is engaged

AI summary
An LED display is provided in the present disclosure. The LED display includes a casing frame and an LED module. The LED module is fixedly connected with the casing frame by a locking knob, chucks and magnets fitted with each other, and positioning holes and positioning posts fitted with each other. The LED display further includes protective covers, a support base, a power rear cover, and a system control box. The protective covers are connected with the casing frame by fitting the positioning posts with the positioning holes. The support base and the casing frame are connected by fitting the positioning posts with the positioning holes and by a quick fixation with screws. The power rear cover is mounted on the system control box by a latch-hinge to facilitate the assembly and disassembly of various portions of the LED display. In addition, the power rear cover is also provided with a backup power supply and a backup receiver card. When any one of a power supply and a receiver card of the LED display fails, a backup power supply or a backup receiver card can be enabled to work, so as to achieve an immediate maintenance of the LED display.
