Solution Overview

Problem

Conventional hammock straps are heavy, bulky, and require substantial stitching, which increases production costs and damage trees when used for suspension, limiting their practicality 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

VSEngineering Contradiction Analysis

1Strength

If conventional hammock straps use substantial stitching to join strap ends, then the connection strength is improved, but the weight and bulk of the strap increase

Engineering Contradiction:

Improveconnection strengthVSAvoidstrap weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The patent replaces the mechanical stitching system with a woven fabric construction where the eyelet is integrated into the strap structure through weaving. The strap ends are joined by weaving the fabric itself rather than using separate stitching elements, eliminating the need for substantial stitching while maintaining connection strength through the inherent tensile properties of the woven material.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent merges the eyelet formation and strap joining functions into a single integrated woven structure. Rather than separately stitching the strap ends together and then forming eyelets, the weaving process simultaneously creates both the joined strap structure and the eyelet openings, reducing overall weight and bulk by eliminating redundant structural elements.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If conventional hammock straps use folded and sewn hook points, then the attachment reliability is improved, but the bulk and weight increase

Engineering Contradiction:

Improveattachment reliabilityVSAvoidstrap bulk

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent replaces the folded and sewn hook point mechanism with a woven fabric eyelet structure. The reliability previously achieved through mechanical folding and stitching is substituted by the inherent strength and stability of the woven fabric construction, where the eyelet openings are formed directly through the weaving pattern rather than through folded sections that require stitching to secure.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the unnecessary folding and stitching operations from the hook point formation process. By taking out the redundant mechanical elements (folds and stitches) and relying solely on the woven fabric structure to provide the attachment points, the bulk and weight are reduced while maintaining attachment reliability through the strength of the woven material.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If conventional hammock straps use rope to tie to trees, then the suspension function is achieved, but tree damage occurs

Engineering Contradiction:

Improvesuspension functionVSAvoidtree damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a woven fabric strap as an intermediary between the hammock and the tree. Instead of using rope that can cut into or damage tree bark, the wider distributed contact area of the woven fabric strap spreads the load across a larger surface area of the tree, preventing concentrated stress points that cause damage while maintaining the suspension function.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Ease of operation

If campers carry heavy beds for camping, then sleeping comfort is improved, but the weight and space requirements increase

Engineering Contradiction:

Improvesleeping comfortVSAvoidgear weight

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The patent creates a simplified version of a bed structure by using the hammock strap system to provide elevated, comfortable sleeping support. Rather than carrying a full bed frame and mattress, the woven fabric straps create a suspended platform that replicates the essential comfort function of a bed while using minimal material, significantly reducing weight and space requirements for campers.

Inventive Principle:

Principle #26Copying

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.
