Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hammocks are inconvenient to install and use due to simple fastening devices, require uncomfortable sleeping postures, and are either large and non-portable or lack stability, making them unsuitable for outdoor activities.
Innovation Solution
A hammock design featuring a flexible fabric fixedly connected to a foldable frame, with hanging assemblies and pivot shafts that allow for stable unfolding and compact folding, ensuring comfort, stability, and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the hammock uses a simple fastening device to tie fabric to trees, then the structure is simple, but it is inconvenient to install and use
Solution Approach 1:
The hammock is divided into modular components including a foldable frame with multiple segments, hanging assemblies with adjustable straps, and a separate fabric body. This segmentation allows each component to be independently assembled and adjusted, significantly improving installation convenience while maintaining structural simplicity.
Solution Approach 2:
The hammock employs a dynamic foldable frame structure that can transition between unfolded and folded states through pivot connections. The hanging assemblies feature adjustable straps that can be customized for different tree configurations. This dynamic design enables easy installation and portability without requiring complex fixed structures.
2Ease of operation
If the hammock is designed to be portable with foldable structure, then it is easy to carry, but it may lack stability when unfolded
Solution Approach 1:
The foldable frame includes pre-configured pivot connections and限位 portions that automatically engage when the frame is unfolded, ensuring proper geometric arrangement and inherent stability. The hanging assemblies are pre-designed with appropriate strap lengths and connection points, allowing stable suspension without requiring complex assembly procedures.
Solution Approach 2:
The hammock structure is designed to automatically stabilize itself when unfolded, with the pivot shafts and限位 portions working together to maintain fixed geometric relationships. The fabric tension from suspension further stabilizes the frame structure, eliminating the need for additional stabilization mechanisms.
3Ease of operation
If the hammock body frame is made foldable, then it becomes portable, but the fabrication becomes complex
Solution Approach 1:
The frame is segmented into standardised components (support rods, connectors, pivot shafts) that can be manufactured separately using conventional processes and then assembled. This modular approach simplifies manufacturing while enabling foldability, as each segment can be produced independently with standard tolerances.
4Device complexity
If existing hammocks use simple fabric tied to trees, then the structure is simple, but the user has to curl up which makes sleeping uncomfortable
Solution Approach 1:
The foldable frame structure dynamically adjusts to provide optimal suspension angles and fabric tension when unfolded, creating a flat, comfortable sleeping surface. The hanging assemblies can be adjusted to achieve the ideal hammock angle for comfort, transforming the simple fabric into a ergonomically supportive resting surface.

AI summary
A hammock includes a hammock body and a hammock support, where the hammock body includes a fabric and a hammock body frame; the fabric is made of a flexible material and is fixedly connected to the hammock body frame; the hammock body is connected to the hammock support through hanging assemblies; and the hammock body frame is longitudinally foldaway from an unfolded state to a half-folded state and transversely foldaway from the half-folded state to a fully folded state. The hammock body is foldaway, and the fabric is large, comfortable and portable. When the hammock body is unfolded, the hammock is stable and will not collapse. When the hammock body is fully folded, the structure is compact and not easy to loosen.
