Foldable Display Stand with Integral Brace for Self-Erecting Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable display stands made of cardboard or corrugated board are difficult to assemble, fold, and store due to bulkiness, lack of rigidity in the base, and require labor-intensive adhesive attachment of separate pivotable braces, which hinders efficient self-erecting and folding operations.
Innovation Solution
A foldable display stand with an integrally formed pivotable brace and geometric design on a single cardboard or corrugated board that allows for easy assembly, folding, and unfolding, featuring a hexagonal panel and trapezoidal shapes with slots and fold lines to form a pivotal brace without adhesive attachment, enhancing rigidity and simplifying the folding and unfolding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a foldable display stand is made from a single sheet material with pre-arranged fold lines, then it is cost effective to fabricate and transport, but it becomes difficult and time consuming to assemble and fold to collapsed condition
Solution Approach 1:
The stand is divided into multiple functional panels (front panel, rear panel, side panels, base panels) connected by fold lines, allowing each segment to move independently during folding and unfolding operations
Solution Approach 2:
The stand incorporates dynamic elements including elastic cords that provide tension to assist automatic unfolding, and pivotable brace panels that rotate from vertical to horizontal positions to force panels apart during erection
2Extent of automation
If elastic cords are incorporated to enable automatic self-erecting, then the stand can unfold automatically, but it becomes awkward and difficult to fold into folded condition
Solution Approach 1:
Pivotable brace panels serve as intermediary elements that force the front and rear panels apart during unfolding, working in conjunction with elastic cords to achieve automatic erection while simplifying the folding process
3Ease of operation
If a pivotable brace panel is added to force unfolding, then the stand can effectively unfold from collapsed condition, but it requires labor intensive adhesive attachment and increases fabrication time
Solution Approach 1:
The pivotable brace panel is integrally formed with the front or rear panel as a single piece of cardboard or corrugated board, eliminating the need for separate adhesive attachment operations and reducing fabrication time
4Volume of moving object
If the stand is folded for some time, then it can be stored compactly, but the cardboard retains folded condition and becomes difficult to unfold
Solution Approach 1:
The pivotable brace panel dynamically rotates from a vertical position (during storage) to a horizontal position (during unfolding) to force panels apart, overcoming the cardboard's tendency to retain folded condition
Solution Approach 2:
The pivotable brace panel acts as a mechanical intermediary that provides the necessary force to separate panels during unfolding, compensating for the elastic cords' insufficient tension after prolonged folding
5Strength
If side walls are double-folded inward to increase rigidity, then the base can support attachments, but folding and unfolding operations become very difficult
Solution Approach 1:
The base is segmented into multiple panels connected by fold lines, allowing the structure to maintain rigidity when erected while enabling easy folding when collapsed
Solution Approach 2:
The side walls dynamically change configuration between erected and folded states, providing rigidity support for attachments during use while allowing smooth folding operations during storage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The stand is easily erectable and collapsible, with improved rigidity and reduced assembly time, facilitating both folding and unfolding operations while maintaining stability and ease of use.
Implementation Method 1
Some stands incorporate elastic cords which are stretched to the tension condition when the stand is in the folded condition so that the stand may be erected automatically by mainly allowing the elastic cords to pull the various parts of the folded structure to unfold

AI summary
A foldable display support stand is foldable easily and readily into a folded collapsed condition. The stand has a foldable pedestal panel foldable in a horizontal to maintain the stand in a stable erected condition. A pivotal brace extending between the front panel and the rear panel is operative to an extended condition to push the side panels outwards in the erection of the stand, and they are pullable outwards and downwards to initiate the folding operation together with the folding of a pedestal panel upwards to fold the stand into a folded collapsed condition. An elastic cord is connected between the rear panel and the pedestal panel to facilitate the automatic erection of the folded stand to the erected condition.
