Rotatable Multi-Direction Zip-Tie for Rapid Shelter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shelter kits for disaster areas are difficult to assemble quickly due to the complexity of securing components, leaving victims exposed for extended periods before a shelter is ready.
Innovation Solution
A multi-direction zip-tie connector with rotatable fasteners and adjustable straps that can be positioned in various directions to securely attach materials of different shapes and sizes, allowing for rapid assembly of three-dimensional structures like shelters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional shelter kits use standard securing apparatuses, then the structure can be assembled, but the assembly time becomes excessively long (several days)
Solution Approach 1:
The securing system is divided into modular components: a reusable fastener body with ratchet mechanism and disposable straps. This segmentation allows rapid attachment by simply inserting the strap into the pre-positioned fastener, eliminating complex assembly procedures and enabling victims to quickly secure shelter components without specialized tools or training.
Solution Approach 2:
The ratchet mechanism automatically locks the strap in place once inserted, requiring no manual tightening or adjustment by the user. The system self-regulates the tension and secures itself, dramatically reducing the time and skill required for assembly while maintaining secure fastening of shelter components.
2Adaptability or versatility
If multi-directional fastening capability is added to accommodate various materials, then versatility improves, but device complexity increases
Solution Approach 1:
The fastener body is designed as a universal component that can accept multiple straps in different orientations and configurations. A single fastener can accommodate one or more straps depending on the fastening needs, allowing the same device to secure various materials (wood, metal, plastic, fabric) of different shapes and sizes without requiring specialized tools for each material type.
Solution Approach 2:
The system allows dynamic configuration where straps can be added or removed from fasteners based on the specific fastening requirements. The number of active straps per fastener is flexible and adjustable, enabling the structure to adapt to different shelter designs and material arrangements while using the same basic fastening components.

AI summary
A multi-direction zip-tie includes a first zip-tie having a first fastener and a first strap integral therewith, and a second zip-tie having a second fastener and a second strap. The second strap can be integral with a head that engaged with a groove in the second fastener, making the second strap interchangeable. The first fastener and the second fastener are configured to be rotatably engaged with each other by a first ratchet structure. The first zip-tie can have a third strap integrally connected to the first fastener. An extension strap can be engaged with one of the first, second, and third straps to add length. The ability of the first fastener and second fastener to rotate relative to each other allows the straps to be placed in the most advantageous position for connecting and securing materials.
