Foldable Barricade Leg Assembly for Flat Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barricade assemblies lack a convenient and space-efficient design for storage and transit, as they are not easily collapsible or stackable, making them cumbersome to handle and transport.
Innovation Solution
A barricade assembly with a pair of laterally spaced uprights supported by a foldable leg assembly that unfolds to a generally upright position and folds into a flat configuration, allowing for nesting of the legs within each other for easy stacking and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If barricade assemblies are designed with fixed legs for stable support, then structural stability is improved, but storage efficiency and ease of transport deteriorate due to increased space requirements
Solution Approach 1:
The leg assembly is divided into multiple separable segments (front legs and back legs) that can be independently folded and nested within one another. This segmentation allows the legs to be collapsed into a compact configuration for storage while maintaining full extension capability for stable barricade support when deployed.
Solution Approach 2:
The front legs are designed to nest within the back legs when folded, creating a compact hierarchical structure. This nesting arrangement minimizes the volume occupied by the leg assembly during storage and transport while allowing full deployment of all leg segments when the barricade is set up for use.
2Strength
If barricade assemblies use rigid fixed structures for support, then load-bearing capacity is improved, but ease of operation and setup deteriorates due to lack of portability
Solution Approach 1:
The leg assembly transitions from a static fixed structure to a dynamic foldable structure that can change configuration between deployed and stored states. The legs incorporate hinges and connection mechanisms that allow them to be folded flat for portability while maintaining structural rigidity and load-bearing capacity when extended to support the barricade.
3Stability of the object's composition
If barricade assemblies are designed for stable upright support, then functional performance is improved, but stacking efficiency deteriorates due to increased height and volume
Solution Approach 1:
The support structure is segmented into multiple leg sections that can be independently folded. When collapsed, these segments reduce the overall height of the barricade assembly, enabling efficient vertical stacking. When deployed, the segments extend to provide adequate support height for stable upright positioning.
Solution Approach 2:
The legs are designed to fold in a horizontal dimension rather than simply collapsing vertically. This allows the barricade to maintain its functional width and depth while reducing height during storage, optimizing stacking efficiency without compromising the structural integrity needed for upright support during use.

AI summary
A barricade assembly comprises a pair of laterally spaced uprights for supporting at least one barricade board, and a foldable leg assembly for selectively supporting the uprights in a generally upright position. The leg assembly comprises two pairs of legs, one of which has a sliding connection with the respective uprights, and the other of which has a pivotal connection with the respective legs of the one pair and with the respective uprights. When the legs of both pairs are unfolded, the legs of both pairs support the uprights in a generally upright position, whereas when the legs of both pairs are folded, the legs of the one pair are nested within the legs of the other pair substantially in line with the inner sides of the respective uprights to provide a substantially flat barricade assembly for ease of stacking of a plurality of such barricade assemblies on top of one another during storage and/or transit.
