Connecting Piece for Portable Display Sign Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing freestanding portable display signs require significant labor and time for mounting and demounting due to complex connections between legs and a crossbar, and often involve multiple component members.
Innovation Solution
A connecting piece that associates legs and a crossbar with spring members, allowing simultaneous connection via shared fixing means, minimizing the number of components and simplifying the assembly process, with optional spring members to absorb wind loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each leg member and spring member is independently connected to the coupling and crossbar respectively, then the connection is stable and reliable, but considerable effort and time are needed for mounting and demounting the display sign
Solution Approach 1:
The patent combines multiple independent connection operations into a single integrated connecting piece that simultaneously connects both leg members to the crossbar. The connecting piece includes mounting openings that receive both legs, and a single fixing means (such as a bolt or pin) secures both legs to the crossbar at the same time, eliminating the need for separate connection steps for each leg member.
Solution Approach 2:
The connecting piece serves multiple functions: it connects both leg members to the crossbar, provides mounting openings for receiving the legs, and incorporates the fixing means for securing the connection. This multi-functional component replaces what would otherwise require multiple separate parts and operations, reducing both time and complexity while maintaining connection reliability.
2Strength
If multiple component members are used for connecting legs and crossbar, then the connection is robust, but the number of components increases making assembly more complex
Solution Approach 1:
The patent merges multiple connection components into a single integrated connecting piece. Instead of using separate mounting brackets, individual fasteners for each leg, and additional support elements, the invention provides one connecting piece with integrated mounting openings and fixing means that performs all connection functions in a single component.
Solution Approach 2:
The connecting piece is designed as a universal component that handles all connection requirements between the legs and crossbar. It includes the structural element for attachment, the mounting openings for leg reception, and the fixing means for securing, thereby eliminating the need for multiple specialized components while maintaining connection robustness.

Function Achieved in This Case
The solution reduces labor effort and time for mounting and demounting while using fewer components, ensuring efficient and stable outdoor display setups, even under wind conditions.
Implementation Method 1
at least one spring member supporting underside of the frame (1)
Implementation Method 2
the display card is supported on the cross bar with a pair of spring members which allow the sign to deflect in relation to the support structure when subjected to wind gusts
