Rotating Handle Barricade for Accessible Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barricade systems are not user-friendly and require multiple legs for full deployment, making them difficult for individuals with disabilities to use effectively.
Innovation Solution
A deployable barricade system with a rotatable handle and leg mechanism that transitions between a stowed and deployed state by rotating the handle post 180 degrees, allowing for 90-degree rotation of the leg post, reducing the number of legs needed for deployment and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional barricade systems use multiple legs for full deployment, then the barricade provides adequate support and stability, but the system becomes difficult to deploy and requires more components
Solution Approach 1:
The barricade system is divided into modular components including a body, multiple legs with channels, and handles that can be independently positioned. Each leg is a separate component that can be deployed independently through rotational movement within its channel, allowing the system to be segmented for easier deployment while maintaining structural integrity when assembled.
Solution Approach 2:
The legs are designed to be dynamic rather than static, capable of rotating 90 degrees from a retracted position to a deployed position. This dynamic capability allows the legs to transition between stored and functional states, reducing the number of legs needed at any given time while providing adequate support when deployed.
2Ease of operation
If conventional barricade systems require multiple legs for full deployment, then the barricade provides adequate support, but the system becomes less user-friendly for individuals with disabilities
Solution Approach 1:
The barricade system incorporates handles that enable users to easily grip and rotate the legs into position. The handles are strategically positioned on the legs to provide mechanical advantage, allowing individuals with disabilities to deploy the barricade with minimal effort. The system serves itself by using the user's pulling motion on the handle to automatically rotate the leg into its support position.
3Ease of operation
If the barricade system minimizes the number of legs required for deployment, then ease of use improves, but ensuring adequate support becomes more challenging
Solution Approach 1:
The legs are positioned asymmetrically around the barricade body, with each leg oriented to provide optimal support in different directions. This asymmetric arrangement ensures that even with fewer legs, the barricade achieves stable support by strategically positioning each leg to counteract specific forces and maintain balance in various deployment scenarios.

AI summary
Barricade systems are provided. A barricade system includes a first handle recess, a first channel extending to the first handle recess, a first handle portion including a first handle and a first handle post, and a first leg portion including a first leg and a first leg post. The first handle extends perpendicularly from one end of the first handle post. The first leg extends perpendicularly from one end of the first leg post. The first handle post and the first leg post are rotatably connected to each other. The rotatably connected first handle post and first leg post are disposed within the first channel. The barricade system switches between a stowed state and a deployed state by rotating the first handle post 180 degree. The 180 degree rotation of the first handle post facilitates a 90 degree rotation of the first leg post.
