Origami-Inspired Deployable Barrier for Rapid Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barriers are often large and difficult to transport, and while solutions like folding or modular barriers address size issues, they introduce challenges such as slow expansion, manual assembly, and potential gaps or weaknesses.
Innovation Solution
A barrier system inspired by thick origami, featuring a continuous sheet with integrated rigid sections and hinges formed from the sheet, allowing for rapid deployment and collapse, with the ability to switch between states without creasing or introducing weak points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If barriers are made large to cover sufficient area, then barrier effectiveness is improved, but transportability deteriorates
Solution Approach 1:
The barrier is divided into multiple rigid panels connected by hinges, allowing the structure to be segmented into transportable sections that can be assembled into a large barrier when deployed
Solution Approach 2:
The barrier transitions from a static structure to a dynamic one that can change configuration between collapsed and deployed states through hinge movement, enabling easy transport and rapid deployment
2Volume of moving object
If barriers are made collapsible to improve transportability, then storage size is reduced, but expansion speed deteriorates
Solution Approach 1:
The barrier is pre-assembled with rigid panels and hinges in a compact collapsed configuration, so that when deployment is needed, the structure only requires hinge movement rather than complete assembly, enabling rapid expansion
Solution Approach 2:
The hinge connections enable dynamic movement between collapsed and deployed states, allowing the barrier to transition quickly from compact storage configuration to full deployment without manual reassembly
3Ease of operation
If modular barriers are used to address size issues, then transportability is improved, but structural integrity deteriorates due to potential gaps and cuts
Solution Approach 1:
Multiple rigid panels are merged into a single continuous sheet structure with integrated hinges, eliminating gaps and weak points between modular components while maintaining the ability to collapse for transport
Solution Approach 2:
The barrier uses a continuous sheet structure that provides flexible yet intact coverage, maintaining structural integrity and preventing gaps while allowing collapse through integrated hinge mechanisms

AI summary
An example barrier can be switchable between an at least partially collapsed state and at least partially expanded state (e.g., a deployed state). For example, the barrier can be formed from a continuous sheet and a plurality of rigid sections (e.g., rigid panels) attached or incorporated into the continuous sheet. The barrier can also include a plurality of hinges, such as hinge lines, between the panels that are formed from the continuous sheet. The hinges enable the barrier to be rigid foldable (e.g., the hinges can fold and unfold while the rigid sections remain stiff and rigid) between the expanded and collapsed states.
