Foldable Hammock Frame Using Rotating Rod Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hammocks are bulky and heavy after folding, making them inconvenient to carry and increasing packaging and transportation costs.
Innovation Solution
A hammock frame with two sets of connecting rod assemblies that rotate to fold into a compact shape, reducing volume and allowing for easy handling, without the need for sliding mechanisms or unlocking positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sliding structures are used for folding, then the hammock can be folded, but the structure becomes complex requiring unlocking and locking mechanisms
Solution Approach 1:
The patent replaces the conventional sliding mechanism with a rotating mechanism. Instead of rods sliding into each other requiring locks and unlocks, the rods rotate around connection points to achieve folding and unfolding. This substitution eliminates the need for complex locking mechanisms while maintaining the folding function.
Solution Approach 2:
The hammock frame is divided into multiple independent rod segments (first rod, second rod, third rod, fourth rod, fifth rod, sixth rod) that can rotate relative to each other. This segmentation allows each rod to be independently positioned during folding, simplifying the overall folding operation compared to a monolithic sliding structure.
2Ease of operation
If the hammock is designed for portability, then it should be easy to carry, but the folding mechanism increases structural complexity
Solution Approach 1:
The rotating mechanism replaces complex sliding and locking systems, reducing the overall structural complexity while maintaining portability. The rotation-based folding allows the hammock to be quickly deployed and packed without complex mechanical interventions.
Solution Approach 2:
The rod structure is designed so that rods can be nested or closely positioned during folding. The first rod, second rod, fifth rod, and sixth rod form a W-shape that allows compact nesting, while the third rod and fourth rod form a V-shape that fits within the overall compact structure, minimizing the folded volume for easy carrying.

AI summary
A hammock has a foldable frame. The frame includes two connecting rod assemblies located on lateral sides of the hammock and connected to each other. Each connecting rod assembly comprises first, second, third, fourth, fifth and sixth rods. Tops of the first and second rods are rotatably connected. Bottoms of the third and fourth rods are rotatably connected. The first rod is rotatably connected with the third rod and the second rod is rotatably connected with the fourth rod. A bottom of the first rod is rotatably connected with a bottom of the fifth rod, and a bottom of the second rod is rotatably connected with a bottom of the sixth rod. The fifth and sixth rods each have a positioning groove. Connecting rods rotatably connected to the tops of the third and fourth rods are releasably engageable with the respective positioning groove.
