Front-Accessible Image Module Mounting for LED Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for assembling and disassembling image modules in modular projection screens are cumbersome, particularly due to the need to access screw connections from the rear, which complicates the replacement process.
Innovation Solution
An assembly tool comprising a lower and upper mounting frame with guide rods and screw connections allows for front-side access and manipulation of image modules, enabling easy assembly and disassembly by hiding screw connections under removable corner segments and using a gripping tool for corner segment removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screw connection is located at the rear of the device housing, then the image module can be securely mounted, but the replacement process becomes cumbersome and requires rear access
Solution Approach 1:
The device housing is segmented into front and rear sections, with the screw connection strategically positioned to be accessible from the front. The mounting frame is divided into upper and lower parts that can be independently manipulated, allowing front-side access to fastening mechanisms without compromising structural integrity.
Solution Approach 2:
A mounting frame serves as an intermediary structure between the image module and the device housing. This mounting frame provides guide rods that facilitate alignment and includes integrated screw connections that are accessible from the front, eliminating the need for rear access while maintaining secure mounting.
2Ease of operation
If the screw connection is made accessible from the front, then the replacement process is simplified, but the aesthetic appearance of the device front is compromised
Solution Approach 1:
The mounting frame is designed with differentiated local qualities: the upper mounting frame portion maintains a clean, aesthetic appearance that matches the device front, while the lower mounting frame portion contains the functional screw connections. This allows front accessibility without compromising the visual appearance of the device front surface.
Solution Approach 2:
The screw connections are positioned in a different spatial dimension - specifically in the lower portion of the device front - rather than being distributed across the visible face. This dimensional relocation allows maintenance access while preserving the aesthetic quality of the upper and central front regions.
3Stability of the object's composition
If the image module is securely fastened with multiple screw connections, then the mounting stability is improved, but the assembly and disassembly time increases
Solution Approach 1:
The mounting frame incorporates pre-positioned guide rods and alignment features that automatically guide the image module into correct position during assembly. The screw connections are pre-configured in accessible locations, eliminating the need for complex alignment procedures and reducing assembly time while maintaining secure fastening.
Solution Approach 2:
The mounting system transitions from a static, fixed-position screw connection to a dynamic system where the mounting frame can be independently positioned and adjusted. The guide rods enable smooth insertion and removal movements, making the fastening process more efficient while maintaining stability during operation.
