Adjustable Zipper Fastener for Hammock Cover Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zipper fastener systems in hammocks and similar articles require specific modifications and are not easily adjustable, limiting their versatility in securing and removing connection sections with variable length and location access.
Innovation Solution
A zipper fastener system comprising two tape sections with sliders that can be independently moved along the connection sections, allowing for secure attachment and detachment, enabling adjustable access openings and positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two sliders are used in a zipper fastener system to enable adjustment, then ease of operation is improved, but device complexity increases due to required modifications at the ends
Solution Approach 1:
The zipper fastener system is divided into separate components: a first connection section attached to the hammock and a second connection section attached to the cover. Each section has its own tape with fastener elements, allowing independent attachment and adjustment without requiring complex end modifications to integrate both functions into a single unit.
2Reliability
If connection sections are secured to each other with fixed endpoints, then reliability of attachment is improved, but adaptability decreases due to limited access opening variability
Solution Approach 1:
The zipper fastener system incorporates two sliders that can be independently positioned along the tapes, enabling dynamic adjustment of the access opening to various lengths and locations. This dynamic positioning capability allows the same secure attachment mechanism to adapt to different user needs while maintaining reliable connection through the interlocking fastener elements.
3Device complexity
If zipper fastener system is integrated into single article, then device complexity is reduced, but ease of operation worsens due to inability to adjust from both sides
Solution Approach 1:
The fastener system is segmented into two separate connection sections (first tape section on hammock, second tape section on cover) that can be independently manipulated. This segmentation allows two sliders to be positioned and adjusted from opposite sides of the assembly, providing ease of operation from both sides while keeping each section relatively simple in structure.

AI summary
A hammock assembly is provided and having a fastener, a hammock, and a cover. The fastener includes a first tape section and second tape section corresponding to the first tape section. The hammock includes a hammock body with the first tape section attached to an edge thereof. The cover includes a body with the second tape section attached to an edge thereof, the cover removably attachable to the hammock by connecting the first tape section and the second tape section.
