Self-Erecting Tent With Crossed Resilient Frame Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-erecting tents are either expensive, not durable, have irregular loading on the covering, and provide limited internal space with the covering being limp when erected.
Innovation Solution
A self-erecting tent design utilizing three resilient frame elements that cross under the tent, with arch parts extending between the upper and underside, maintaining a taut covering and distributing load evenly to prevent damage and enhance internal space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional self-erecting tent designs are used, then the tent can be erected rapidly and stored in small volume, but the covering becomes limp and internal space is limited
Solution Approach 1:
The frame is divided into multiple rigid straight segments connected by hinges, allowing the structure to maintain shape while being collapsible. The covering is attached to these segmented frame elements, which cross at two positions to create a stable geometric structure that keeps the covering taut during use but allows compact folding when collapsed.
2Ease of operation
If traditional self-erecting tent designs are used, then the tent can be erected rapidly and stored in small volume, but the production cost is relatively expensive
Solution Approach 1:
The frame uses simple straight segments and hinge connections that are inexpensive to manufacture compared to complex curved resilient structures. The covering can be any standard tent fabric, and the overall design uses common structural elements that reduce production complexity and cost.
3Ease of operation
If traditional self-erecting tent designs are used, then the tent can be erected rapidly, but the structure is relatively little durable
Solution Approach 1:
The rigid segmented frame with hinge connections creates a more durable structure than flexible resilient supports. The straight frame elements resist bending stresses better, and the hinge joints provide reliable connection points. The covering is evenly distributed across multiple crossing frame elements, preventing stress concentration and material fatigue.
Solution Approach 2:
Instead of using flexible resilient materials that degrade over time, the invention inverts the approach by using rigid straight frame elements with mechanical hinge connections. This inverted structure maintains durability while still achieving rapid erection through the collapsible hinge mechanism.
4Ease of operation
If traditional self-erecting tent designs are used, then the tent can be erected rapidly, but the covering is irregularly loaded which can lead to damage
Solution Approach 1:
The covering is supported by multiple segmented frame elements that cross at two positions, creating multiple support points that distribute the load evenly across the covering surface. This segmented support system prevents stress concentration at single points.
Solution Approach 2:
The frame elements are positioned to provide optimized local support across different areas of the covering. The crossing frame elements create a distributed support network that adapts to local loading conditions, ensuring uniform stress distribution throughout the covering material.

Function Achieved in This Case
The design results in a stable, durable, and cost-effective tent with ample internal space, keeping the covering taut and preventing overload, while being easy to set up and fold, maintaining structural integrity and comfort.
Implementation Method 1
at least three resilient frame elements (1, 2, 3) formed into endless loops which stretch a tent covering (4), when the tent is in an erected position
