Solution Overview
Problem
Conventional connecting devices for display cabinets and vertical tubes are labor-intensive to assemble, prone to deformation, and limited in applicability due to precise processing requirements, leading to weak connection strength and potential breakage.
Innovation Solution
A connecting device comprising a first and second connecting frame and a fastening unit that securely clamps the vertical tube between the frames, using multiple fastening sets to distribute pressure evenly and prevent deformation, allowing for easy assembly and adaptation to different display cabinet configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single screw extends through the vertical tube and connecting plate to secure the display cabinet, then the connection is simple to assemble, but the connection strength is insufficient and deformation or breakage may occur
Solution Approach 1:
The single fastening point is segmented into multiple fastening points. The connecting device uses a connecting plate with multiple through holes (at least three) instead of a single screw connection, distributing the load across multiple points to enhance connection strength while maintaining assembly simplicity
Solution Approach 2:
The connection is extended from a single-point (1D) connection to a multi-point distributed connection across the connecting plate. By adding spatial distribution of fastening points in multiple directions, the connection strength is enhanced without significantly increasing assembly complexity
2Manufacturing precision
If the vertical tube is processed to form a through bore with high precision to prevent gaps between display cabinets, then the connection precision is improved, but the manufacturing process becomes troublesome and assembly is time-consuming
Solution Approach 1:
The precision requirement is segmented from the vertical tube to the connecting plate. Instead of requiring high precision in the vertical tube's through bore, the connecting plate incorporates multiple adjustment holes that can accommodate positional variations, reducing the precision requirement for the vertical tube while maintaining overall connection precision
Solution Approach 2:
The design changes from a single precise through bore to multiple holes with adjustable positions. The connecting plate's holes can be positioned at different locations to compensate for manufacturing tolerances, allowing assembly without high-precision processing while maintaining gap-free connections
3Area of stationary object
If a connecting plate with width greater than the vertical tube is used and screws exert force to fasten display cabinets, then the connection coverage is improved, but the connecting plate deforms and the vertical tube warps forwardly forming connection gaps
Solution Approach 1:
The connecting plate is designed with localized reinforcement at critical areas. Strengthening ribs or gussets are added at specific locations where screws apply force, allowing the plate to maintain larger coverage area while resisting deformation at stress concentration points
Solution Approach 2:
The connecting plate uses composite structural design combining different material properties or structural configurations. The plate may incorporate reinforcement elements or use composite materials that provide both large coverage area and high stiffness to prevent warping under screw fastening forces

AI summary
A connecting device for interconnecting a vertical tube and a plurality of display cabinets for carrying display modules includes first and second connecting frames and a fastening unit. The first connecting frame is for mounting the display cabinets thereon, abuts against a front outer surface of the vertical tube facing the display cabinets. The second connecting frame abuts against a rear outer surface of the vertical tube facing away from the first connecting frame. The fastening unit includes first fastening sets fastening the first and second connecting frames together so as to clamp the vertical tube therebetween. The second fastening sets fasten securely the display cabinets to the first connecting frame.
