Folding Hammock Support Structure for Stable Grounded Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable hammocks with dual suspension points at both ends suffer from insufficient stability due to the internal force bearing at the top of the vertical pole being unsupported by the connecting rod groups, leading to instability during use.
Innovation Solution
A folding hammock design featuring a bracket with a landing rod group, support rod group, and associated rod group, utilizing grounding rods with a clamping component to transmit force into the ground, and an auxiliary support rod to enhance stability, while allowing for easy folding and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the side connecting rod group is connected by a long rod and a short rod to achieve folding, then the hammock becomes foldable and portable, but the stability of the support is insufficient
Solution Approach 1:
The support structure is divided into multiple segments: landing rod with support section and landing section, auxiliary support rod, and cross connecting rod groups. This segmentation allows the structure to be folded for portability while maintaining stability when deployed through the triangular configuration of segmented rods.
Solution Approach 2:
The patent introduces a vertical dimension by adding the auxiliary support rod that extends from the landing rod upward to support the bed surface. This vertical element transforms the flat two-dimensional rod arrangement into a three-dimensional stable structure, solving the stability issue while preserving foldability.
2Force
If the lower end of the vertical pole touches the ground directly to guide force into the ground, then force transmission is improved, but the internal force bearing at the top of the vertical pole is unsupported
Solution Approach 1:
The auxiliary support rod acts as an intermediary element between the landing rod and the bed surface. It transfers and distributes the internal forces, providing support at the top of the vertical structure while maintaining the ground connection at the bottom, thus solving both force transmission and strength issues simultaneously.
Solution Approach 2:
The auxiliary support rod is pre-positioned and hinged to the landing rod before the bed surface is loaded. This preliminary structural arrangement ensures that the force-bearing capacity is established in advance, preventing structural failure when weight is applied to the bed surface.
3Stability of the object's composition
If the hinge points of the two grounding rods are located above the center point to form upper shorter support section and lower longer landing section, then the structure can be stabilized, but the complexity of the bracket structure increases
Solution Approach 1:
The landing rod is designed with asymmetric hinge point positioning above the center, creating unequal upper support section and lower landing section. This asymmetric configuration provides inherent structural stability through geometric arrangement while the modular design keeps the overall complexity manageable.
