Tent Sheet Diagonal Folding Lines for Enclosed Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tents with single-piece tent sheets do not effectively create an indoor space separated from the external environment, lacking the necessary structural features for separation.
Innovation Solution
A tent sheet with a rectangular shape featuring straight-line diagonal tension reinforcement folding lines, central tension reinforcement folding lines, and transverse tension reinforcement folding lines, along with symmetric peripheral parts, allows for the formation of an indoor space by tension reinforcement and folding mechanisms, enabling separation from the external environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-piece simple shape tent sheet is used, then storability and damage resistance are improved, but the ability to form an indoor space separated from the external space deteriorates
Solution Approach 1:
The tent sheet is divided into multiple functional regions through folding line parts: corner regions with diagonal folding lines for vertical pole support, side regions with transverse folding lines for horizontal pole support, and central regions for the living space. This segmentation allows the simple rectangular sheet to form a structured three-dimensional enclosed space while maintaining its single-piece simplicity for storage.
Solution Approach 2:
The flat two-dimensional tent sheet transforms into a three-dimensional enclosed space through the folding line parts that create vertical and horizontal dimensions. The diagonal folding lines at corners enable vertical elevation for pole insertion, while transverse folding lines create horizontal ridges, collectively forming a volumetric indoor space separated from the external environment.
2Strength
If diagonal tension reinforcement folding line parts are added to extend from midpoint of short side to vertex side point, then structural strength and space formation are improved, but device complexity increases
Solution Approach 1:
The diagonal folding line parts are localized specifically at the four corner regions of the rectangular tent sheet, extending from the midpoint of each short side toward the adjacent vertices. This local addition provides structural strength where needed for pole support and space formation, while the majority of the sheet remains simple and uncluttered, minimizing overall complexity.

AI summary
A tent sheet is disclosed. The tent sheet is in a rectangular shape having four vertices, two short sides, and two long sides, the tent sheet includes four straight-line diagonal tension reinforcement folding line parts provided corresponding to the four vertices. The four diagonal tension reinforcement folding line parts are each provided to extend from the midpoint or of the short side adjacent to a corresponding vertex of the vertices to a vertex side point which is nearer to the vertex than the midpoint of the long side adjacent to the vertex.
