Hammock With Offset Slit For Diagonal Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hammocks with bottom entrance slits can be uncomfortable, especially in asymmetrical versions where users lie diagonally, as the tension distribution is uneven, leading to discomfort and difficulty in maintaining the slit closed.
Innovation Solution
The hammock design features a laterally offset or bias-cut entrance slit, which remains under tension even when the user changes position from the longitudinal to a diagonal axis, ensuring secure closure and improved comfort by allowing the user to lie away from the tensioned slit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entrance slit is centered on the longitudinal axis of the hammock, then the slit can be effectively closed by tension when lying along the longitudinal axis, but it causes discomfort when users lie diagonally across the tension axis
Solution Approach 1:
The patent applies asymmetry by positioning the entrance slit offset from the longitudinal centerline of the hammock. Specifically, the slit is located at a distance of 0.1 to 0.4 times the hammock width from the centerline. This asymmetric positioning allows the slit to remain under effective tension when users lie diagonally across the tension axis, resolving the contradiction between slit closure reliability and user comfort.
2Ease of operation
If the hammock is made asymmetrical to encourage diagonal lying, then user comfort is improved, but tension distribution becomes uneven making it difficult to maintain slit closure
Solution Approach 1:
The patent applies local quality by creating an asymmetric tension distribution pattern through the offset slit position. The slit is positioned to be 0.1 to 0.4 times the hammock width from the centerline, which concentrates tension forces locally at the slit location when users lie diagonally. This localized tension concentration ensures reliable slit closure while maintaining the overall asymmetric hammock configuration for user comfort.
3Device complexity
If a centered entrance slit is used, then the design is simple and symmetrical, but it requires additional slits in insulation panels and complicates integration of thermal insulation
Solution Approach 1:
The patent applies asymmetry by positioning the entrance slit offset from the longitudinal centerline at a distance of 0.1 to 0.4 times the hammock width. This asymmetric positioning eliminates the need for additional slits in insulation panels, as the offset location allows for simpler integration of thermal insulation layers without requiring centered openings, thereby reducing manufacturing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances user comfort by maintaining slit tension and closure, even when lying diagonally, and simplifies the integration of insulation panels without requiring additional slits, improving overall hammock usability and comfort.
Implementation Method 1
tension of the bottom fabric is spread over a wider area, allowing the entrance slit to remain under tension even when offset to one side of the longitudinal axis of the hammock
Data Source
AI summary
A hammock having a self-closing bottom entrance slit is constructed with the slit substantially offset to one side of the center line of the hammock. This improves comfort by enabling one to lie in the hammock out of contact with the slit, and facilitates the addition of an insulating panel to the hammock.
