Multi-positional Closure Fastener with Rotatable Receivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zip ties and cable ties face stress and wear due to the difficulty in fastening multiple-directional and multi-elevational straps, particularly in complex wiring and tubing systems, where the angle of engagement between the closure fastener and the tab often results in stress on the straps and wires, leading to chafing and breakage.
Innovation Solution
A multi-positional closure fastener with receivers oriented at different angles and elevations, featuring tapered sidewalls for rotational motion and adaptable openings, allowing for secure fastening of straps from various directions while minimizing stress, and incorporating a ratcheting mechanism for adjustable tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single closure fastener is used to fasten straps from multiple directions, then the fastening capability is simplified, but stress and wear on the straps increase due to odd angles and frictional engagement
Solution Approach 1:
The closure fastener is divided into multiple receiver components (first receiver, second receiver, third receiver) that are spatially separated and oriented at different angles. Each receiver independently handles straps from specific directions, preventing stress concentration and frictional wear that would occur with a single unified fastener.
Solution Approach 2:
The receivers are positioned at different spatial orientations and elevations, creating a three-dimensional fastening structure. This allows straps to engage the fastener from multiple directions (horizontal, vertical, angled) without creating stress points, as each receiver is optimized for its specific orientation.
2Ease of operation
If the closure fastener is oriented for straight-line fastening, then the fastening mechanism is simple, but it cannot accommodate straps that need to loop around corners and through tight channels
Solution Approach 1:
The fastening system transitions from a fixed, single-orientation closure to a dynamic multi-orientation system with receivers positioned at various angles. This allows the fastener to adapt to different strap routing requirements (straight lines, corners, channels) while maintaining simple individual fastening mechanisms at each receiver location.
Solution Approach 2:
The multi-positional closure fastener serves multiple functions: it can fasten straps in straight lines, around corners, through tight channels, and at various elevations. Each receiver is designed with the same basic fastening mechanism but oriented differently, providing universal applicability across diverse strap routing scenarios.
3Length of stationary object
If the strap is stretched to create a larger loop, then the loop diameter increases, but the strap experiences greater stress and potential breakage
Solution Approach 1:
The receivers are pre-positioned at multiple locations and orientations along the fastening path, allowing the strap to engage sequentially without stretching. The strap can follow a natural path through channels and around corners, engaging each receiver in turn, which eliminates the need to stretch the strap to achieve larger loop diameters.
4Adaptability or versatility
If multiple closure fasteners are used to provide entry options from different angles, then the adaptability increases, but the device complexity increases
Solution Approach 1:
The complex multi-angle fastening requirement is segmented into multiple independent receiver components, each handling a specific direction. This segmentation allows each receiver to maintain a simple, proven fastening mechanism while the overall system provides comprehensive angular coverage through the arrangement of multiple receivers.

AI summary
A multi-positional closure fastener includes a plurality of receivers that orient at different relative angles and elevations. The receivers include tapered sidewalls that enable rotational motion between adjacent receivers. This multi-positional disposition of adjacent receivers facilitates the reception by the receivers of zip tie-styled straps from multiple angles, elevations, and directions. This is because there are greater possibilities of proximity between the straps and the receivers due to the multiple possible orientations and flexible movement of the receivers. This proximal positioning creates a more aligned, linear connection between corresponding receivers and straps; thus resulting in reduced stress on the straps. Each receiver comprises a housing having an opening. The openings are where the insertion tab from the straps are inserted and fastened into place. A fastening mechanism in the opening of the housing locks with an insertion tab from the strap to form the fastened closure.
