Ventilated Tent Cloth Rope Ventilation Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilated tents have complex structures and are prone to water ingress through ventilation gaps, which compromises their effectiveness in windy and rainy conditions.
Innovation Solution
A ventilated tent design featuring tent cloths and a frame with a cloth rope system that creates a ventilation gap between the top and side cloths, using a buttonhole and circular ring structure for connection, and a simple supporting rod framework with concave bolt connections to prevent water entry and facilitate easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple support rods are used to control the air permeable gap between layers, then ventilation is achieved, but the structure becomes complicated
Solution Approach 1:
The patent extracts the ventilation control function from the complex multi-rod support system and concentrates it into a single pull rod that directly controls the movable connection between the first and second main mandrels, simplifying the structure while maintaining the ventilation capability
Solution Approach 2:
The pull rod serves multiple functions: it acts as both a support element and a ventilation control mechanism, replacing the need for separate control rods by integrating the ventilation function into the existing support structure
2Reliability
If a vent is set on top of the tent body, then ventilation is achieved, but water easily enters into the tent
Solution Approach 1:
The patent employs a dynamic ventilation mechanism where the gap between the first and second top cloths can be adjusted by pulling the pull rod, allowing the ventilation opening to be controlled and closed when needed to prevent water ingress, rather than having a fixed vent
Solution Approach 2:
The patent uses flexible tent cloths that can be moved relative to each other to create controllable ventilation gaps, allowing the structure to adapt to different weather conditions by adjusting the cloth positions

AI summary
A ventilated tent includes a tent cloth, a tent frame, a cloth rope and a buttonhole; the tent cloth is set on the tent frame fixedly connected with the tent frame; the tent cloth includes a top cloth, a front cloth, a back cloth, a left side cloth and a right side cloth; left and right ends of the top cloth cover top of the left side cloth and the right side cloth; the buttonhole is fixed at an edge of the tent cloth, the cloth rope connects the top end of the left side cloth and the top end of the right side cloth through the buttonhole, and a ventilation gap is formed when top end of the left side cloth and right side cloth go away from left end and tight end of the top cloth by tightening and relaxing the cloth rope.
