Tent Frame Reinforcing Bar for Hinge Stability and Water Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tents with folding frame structures are prone to hinge failure and water accumulation at the central triangular inclined planes, leading to a short service life, especially in rainy conditions.
Innovation Solution
A reinforced frame-supporting structure featuring a top disc, vertex angle support bars, hinged beams, frame-reinforcing support bars, and telescopic support bars that provide stability and prevent water accumulation by connecting the hinged beams to the top disc and foot bar supports, forming a firm anti-bending structure and reducing fold-up volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a folding frame structure with hinges is used to enable easy carrying and storage, then the tent is easy to use and portable, but the hinges are prone to breaking or bending, reducing reliability and service life
Solution Approach 1:
The patent applies beforehand cushioning by providing reinforcing support bars positioned to prevent hinge bending before it occurs. The support bars are arranged to contact the inner surfaces of the folding frame's longitudinal beams, creating preventive reinforcement that stops hinge failure before it happens, especially at the critical middle sections where bending is most likely during rainy conditions
Solution Approach 2:
The patent applies segmentation by dividing the folding frame structure into multiple segments with reinforcing support bars placed at specific intervals. The frame is segmented into sections with reinforcement at middle portions and end portions, allowing each segment to be independently strengthened without compromising the overall folding functionality
2Object-affected harmful factors
If the tent fabric is designed with triangular inclined planes for drainage, then water can drain during rainy days, but the central portion sags and accumulates water, causing the tent to fall down
Solution Approach 1:
The patent applies beforehand cushioning by positioning reinforcing support bars to prevent sagging before it occurs. The support bars are arranged to contact the inner surfaces of the longitudinal beams at strategic locations, providing preventive reinforcement that stops the fabric from sagging and accumulating water in the first place
Solution Approach 2:
The patent applies local quality by providing differential reinforcement at different locations of the folding frame. The middle portions and end portions receive reinforcing support bars, while other areas maintain their original structure. This localized reinforcement strategy strengthens critical areas prone to sagging without adding unnecessary weight or complexity throughout the entire structure
3Reliability
If reinforcing support bars are added to prevent hinge bending and water accumulation, then reliability and stability are improved, but the structural complexity increases
Solution Approach 1:
The patent applies local quality by providing differential reinforcement at different locations of the folding frame. The middle portions and end portions receive reinforcing support bars, while other areas maintain their original structure. This localized reinforcement strategy strengthens critical areas prone to sagging without adding unnecessary weight or complexity throughout the entire structure
Solution Approach 2:
The patent applies dynamics by designing the reinforcing support bars to work in conjunction with the folding mechanism. The support bars are positioned to provide reinforcement when the frame is deployed, but do not interfere with the folding operation, allowing the structure to dynamically transition between deployed and folded states while maintaining reliability

AI summary
A tent with a reinforced frame-supporting structure is provided, comprising a top disc (1), a plurality of vertex angle support bars (2) whose tops are circumferentially and obliquely connected with the top disc (1), foot bar supports (3) connected with the bottom of each vertex angle support bar (2), hinged beams (4) arranged between two adjacent vertex angle support bars (2), wherein either end of the hinged beams (4) is connected with the upper end of adjacent foot bar supports (3) respectively, a frame-reinforcing support bar (5) is provided between the hinged beam (4) and the top disc (1) whose top is obliquely connected with the top disc (1) and bottom is connected with the middle hinged portion of the hinged beam (4). The tent has the advantages of reinforced-frame structure, increased-hinge stability and prevention of water accumulation in the middle of the inclined plane of the top fabric.
