Universal Hub Adapter for Multi-Panel Portable Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable display systems are not compatible for mounting both multiple stretchable fabric panels and large framed panels, requiring separate systems for each type, leading to increased inventory and limited configuration options.
Innovation Solution
A universal hub adapter and universal hub assembly that allow a single collapsible frame to interchangeably mount both multiple stretchable fabric panels and sub-frames for larger graphic panels, utilizing a faceplate and threaded post configuration to secure various graphic systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate display systems are used for stretchable fabric panels and large framed panels, then each system can be optimized for its specific graphic system type, but inventory requirements increase and configuration options are limited
Solution Approach 1:
The hub assembly is designed with a universal interface that can accommodate both stretchable fabric panels and large framed panels through a standardized mounting mechanism. The faceplate with multiple hole patterns and the threaded post configuration enable a single hub design to support multiple graphic system types, eliminating the need for separate specialized hubs for each panel type.
2Adaptability or versatility
If a single frame assembly supports multiple graphic system types, then inventory needs are reduced and configuration flexibility increases, but the hub design becomes more complex
Solution Approach 1:
The hub assembly is divided into distinct functional components: a hub body for structural support, a faceplate with multiple hole patterns for different mounting configurations, and a threaded post mechanism for securing panels. This segmentation allows each component to be optimized for its specific function while collectively providing universal compatibility.
Solution Approach 2:
The faceplate acts as an intermediary element between the hub body and the various graphic panels. It provides a standardized interface with multiple hole patterns that can accommodate different panel types, simplifying the connection process while maintaining design flexibility.
3Ease of operation
If stretchable fabric panels are attached directly to hubs with convex surfaces, then attachment is simple using buttonholes, but the fabric edges arch inward causing image distortion
Solution Approach 1:
The faceplate serves as an intermediary between the hub and the fabric panel, providing a flat mounting surface that prevents fabric edge arching. The multiple hole patterns in the faceplate allow for optimized attachment points that maintain fabric tension and flatness while preserving the simplicity of buttonhole attachment.

AI summary
A universal hub adapter for a portable display frame assembly, the hub adapter being configured to mount to an outer surface of a display hub of the frame assembly. The universal hub adapter is configured to adapt the display hub of the frame assembly between the mounting of a first graphics system including a plurality of stretched fabric panels and a second graphics system including a channeled sub-frame for mounting a larger fabric panel. The universal hub adapter can include a faceplate having a substantially planar outer surface and a concave inner surface configured to mate with the convex outer surface of the display hub and a threaded post having a threaded portion, a securement plate, a button shaft, and a button head, the threaded portion configured to pass through an aperture of the faceplate and couple to the display hub, such that the securement plate abuts up against the faceplate thereby securing the faceplate to the display hub, the button shaft and button head configured to operably couple to one of a stretched fabric panel or a sub-frame assembly.
