Pennant Sign Casing With Sliding Access for 5G Unit Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing advertising signs, especially those with integrated wireless communication units, require inefficient and cumbersome maintenance due to sealed casings that complicate access for repair and maintenance, particularly at height.
Innovation Solution
A pennant-type advertising sign with a frame and enveloping casing equipped with rolling elements and wheels that facilitate quick and easy opening, allowing direct access to internal units for maintenance or repair operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the advertising sign uses a sealed casing configuration, then the structural integrity and protection of internal units is improved, but the ease of access for maintenance and repair operations deteriorates
Solution Approach 1:
The casing is divided into multiple separable parts (first casing part and second casing part) that can be detached from each other. This segmentation allows maintenance personnel to open the casing by separating the parts, providing easy access to internal telecommunication units while maintaining structural integrity when closed.
Solution Approach 2:
The casing transitions from a static sealed structure to a dynamic structure with movable elements. Rolling elements (wheels or rollers) are incorporated to enable the casing parts to move relative to each other, facilitating easy opening and closing operations while maintaining protection when closed.
2Ease of manufacture
If the advertising sign uses conventional attachment elements for assembly, then the manufacturing simplicity is improved, but the time commitment and operational comfort for assembly/disassembly deteriorates
Solution Approach 1:
Conventional mechanical attachment elements (screws, bolts, clips) are replaced with a magnetic attachment system. The first and second casing parts incorporate magnetic elements that provide automatic attraction and secure bonding when brought together, eliminating the need for manual fastening operations and significantly reducing assembly time.
3Device complexity
If the advertising sign is designed as a sealed box replaced upon damage, then the device complexity is reduced, but the productivity for maintenance operations deteriorates
Solution Approach 1:
The casing is segmented into detachable parts with rolling elements that enable easy separation and reassembly. This allows maintenance personnel to access internal units for repairs without replacing the entire casing structure, significantly improving maintenance productivity while maintaining simple device architecture.
Solution Approach 2:
The magnetic attachment system provides self-aligning and self-locking functionality when the casing parts are brought together. The magnetic force automatically guides the parts into proper alignment and secures them, reducing the skill level and time required for maintenance operations.

AI summary
The sign incorporates a frame (1) comprising an upright (3), upper and lower structures (4, 5) that extend from the upright (1) cantilevered, between which telecommunication units are arranged, including a 5G antenna, as well as the sign incorporates a casing (2). The casing is movable with respect to the frame to facilitate the performance of maintenance operations on the telecommunication units by means of a sliding system, the upper structure (4) and the lower structure (5) incorporating for this purpose first wheels (12) intended to establish contact with internal faces of the casing (2) when it 10 moves the casing (2) with respect to the frame (1), just as the casing (2) has on two of the internal faces thereof second wheels (13) that move guided on the upper structure (4).
