Biconvex Micro-Mesh Hammock Lying Surface Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional poleless hammocks without slats are unstable, prone to collapse, and sensitive to weather conditions, leading to a bent sleeping position and material degradation from rain, saltwater, and sunlight.
Innovation Solution
The hammock features biconvex micro-mesh fabric webs made of PVC-coated microgrid fabric, connected to form a flat lying surface with pretension, and reinforced with heavy-duty straps for stability, using high-quality, tear-resistant, and weather-resistant materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional poleless hammocks are made without slats using cotton material, then the hammock structure is simple and easy to manufacture, but the hammock becomes unstable, collapses when not in use, and the lying surface folds over the person
Solution Approach 1:
The fabric webs are shaped as biconvex blanks with curved surfaces. This curvature creates inherent structural stability and prevents collapse when the hammock is not in use, while maintaining simplicity in manufacture through mold-based shaping of the fabric webs.
Solution Approach 2:
The hammock lying surface is divided into multiple individual fabric webs arranged in the longitudinal direction. These segmented webs are connected by suspension elements to form a stable structure that resists collapse and maintains form stability during use.
2Ease of operation
If cotton material is used for the hammock, then the material is soft and comfortable, but it becomes highly sensitive to rain, salt water, and sun, promoting mold stains, fatigue, and discoloration
Solution Approach 1:
The fabric webs are made from synthetic materials such as polyester or polypropylene, which combine the desired softness and comfort with high resistance to rain, salt water, UV radiation, mold, and discoloration. This composite material approach eliminates weather sensitivity while maintaining comfort.
3Device complexity
If the hammock is made without form stability, then the structure is simple, but the body of the lying person hangs in a bent position causing discomfort
Solution Approach 1:
The biconvex curved shape of the fabric webs provides inherent form stability that supports the lying person's body in a natural, comfortable position. This curvature creates arches that distribute weight evenly and prevent the body from hanging in a bent position, all while maintaining relatively simple construction.
4Ease of manufacture
If the lying surface is not flat or open, then the manufacturing process is simpler, but the comfort and stability during use is reduced
Solution Approach 1:
The lying surface is formed by arranging multiple biconvex fabric webs in the longitudinal direction and connecting them with suspension elements. This segmentation creates an open, essentially flat lying surface structure that provides comfort and stability while maintaining manufacturing simplicity through modular assembly.

AI summary
The present invention relates to a hammock (1) with a lying surface (2) which consists of fabric panels (3) arranged longitudinally in the hammock (1) and can be suspended between two fixed suspension points (5) by means of suspension elements (4). According to the invention, the hammock (1) is characterized in that the individual fabric panels (3) consist of essentially biconvexly shaped cutouts of a micro-mesh fabric, which are fixed to one another at their respective edges to form a lying surface (2). Particularly preferably, the sections of the webbing (7a, 7b) projecting from the fabric panels (3) and the end sections of the webbing (6) have different lengths, such that the projecting sections shorten from the outside to the inside. This results in particularly high lying comfort and high inherent rigidity of the hammock (1).
