Rotatable Multipositional Fastener Reduces Strap Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems, such as zip ties, face challenges when securing multiple wires and tubes due to stress caused by chafing and friction, especially when oriented at odd angles or passing through tight channels, limiting their versatility and durability.
Innovation Solution
A rotatable multi-positional fastening system with receivers that can pivot and orient at different angles and elevations, allowing for flexible engagement of straps from various directions, reducing stress on the straps by providing multiple entry options and using tapered sidewalls for slight rotational motion between adjacent receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed-position closure fastener is used, then the structure is simple, but the strap cannot accommodate multiple directions and angles without stress and chafing
Solution Approach 1:
The closure fastener is divided into multiple receiver components, each capable of receiving strap ends from different directions. The receivers are arranged in a cluster configuration, allowing independent positioning of each receiver to accommodate straps approaching from various angles and elevations without creating stress concentrations.
Solution Approach 2:
The receivers are positioned in three-dimensional space rather than being confined to a single plane. This spatial arrangement allows straps to approach the closure fastener from multiple directions including top, bottom, sides, and angled approaches, eliminating the need for straps to bend sharply or pass through tight channels.
2Reliability
If the strap is forced to pass through tight channels and bend around corners, then the fastening can be achieved, but the strap experiences greater stress and wears down faster
Solution Approach 1:
The receivers are pre-positioned in multiple locations and orientations before the fastening operation. This allows the strap to be routed smoothly through the system without requiring sharp bends or passage through tight channels during installation, reducing mechanical stress and preventing chafing from the outset.
3Adaptability or versatility
If the closure fastener is oriented at odd angles, then it can accommodate complex wiring configurations, but the strap experiences stress and chafing
Solution Approach 1:
Each receiver in the cluster is independently oriented to match the specific direction from which its associated strap approaches. This localized optimization ensures that each strap-engagement point is aligned with minimal stress, while the overall assembly maintains high adaptability to complex wiring configurations.

AI summary
Rotatable multipositional fasteners, devices, systems and methods having fastener receivers attachable and detachable by male and female parts. Each receiver can receive plural ends of straps, such as zip ties, having greater versatility than existing fastening systems. The multi-positional disposition of adjacent rotatable receivers facilitates the reception by the receivers of straps from multiple angles, elevations, and directions. Greater possibilities of proximity between the straps and the receivers can be due to the multiple possible orientations and flexible movement of the receivers. Proximal positioning creates a more aligned, linear connection between corresponding receivers and straps, resulting in reduced stress on the straps. Each receiver can have a plural openings where the insertion ends of the straps are inserted and fastened. A fastening mechanism in the openings of the housing locks with a strap end to form the fastened closure. Other openings in the housing allow for a strap to pass through both sides of the housing.
