Woven Hammock Strap Eyelets for Low-Bulk Tree-Safe Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hammock straps are heavy, bulky, and require substantial stitching, which increases production costs and damage trees when used for suspension, making them impractical for outdoor camping due to weight and space constraints.
Innovation Solution
A single-piece hammock strap made from woven synthetic fibers, where the strap is separated into two parts at specific points to form eyelets, reducing bulk and weight while maintaining strength through mechanical connections that eliminate the need for excessive stitching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional hammock straps use folded over portions and substantial stitching to provide strength, then the strap can support camper weight, but the overall bulk and weight of the strap increases
Solution Approach 1:
The strap is divided into multiple loops of varying sizes distributed along its length, allowing the hammock to be suspended at different heights without requiring folded portions. This segmentation provides multiple attachment points while maintaining a flat, compact structure that reduces bulk.
Solution Approach 2:
The patent changes the structural parameters of the strap by creating a series of loops with different diameters along the strap length. This allows the strap to provide multiple suspension heights and maintains strength through the loop structure itself rather than through folding and stitching, thereby reducing bulk.
2Strength
If conventional hammock straps use substantial stitching to attach loops, then the strap provides adequate strength, but production costs increase
Solution Approach 1:
The loop structures are integrated directly into the strap during manufacturing, eliminating the need for separate stitching operations to attach loops. The loops are formed as part of the strap's continuous structure, which reduces production steps and costs while maintaining the strength needed to support camper weight.
3Ease of operation
If campers use rope to tie hammock ends to trees, then the hammock can be suspended, but the rope slips or slides down the tree causing the camper to drop
Solution Approach 1:
The strap is divided into multiple loops of varying sizes that can be independently attached to trees at different heights. This segmentation provides multiple secure attachment points along the strap, preventing the slipping problem associated with single-point rope attachments by distributing the suspension function across multiple fixed loops.
4Ease of operation
If campers cut branches to allow rope around trees, then the hammock can be tied, but substantial damage is caused to trees
Solution Approach 1:
The multiple loops along the strap enable attachment at various heights without requiring branches to be cut. Campers can select from multiple loop positions to match available tree heights, eliminating the need to modify trees and thereby preventing the harmful cutting action while maintaining attachment capability.
5Object-affected harmful factors
If conventional hammock straps use folded over portions to prevent tree damage, then tree damage is reduced, but the strap bulk increases
Solution Approach 1:
Instead of using folded portions, the patent employs multiple integrated loops along the strap that provide the same tree-protection function. The loops are formed as part of the strap's flat structure, preventing the need for folding while reducing bulk compared to conventional designs that require folded-over sections for attachment.

AI summary
This disclosure generally relates to a hammock strap. The hammock strap includes an elongated length of strap material that is separated into a first strap and a second strap. The first strap and the second strap are woven together at one or more separation points to form eyelets between the first strap and the second strap.
