Deployable Tent Cover Mechanism Without Manual Support Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deployable tents require manual installation of metal rods to deploy the cap, which is time-consuming, dangerous, and prone to misplacement, especially when placed on a vehicle roof, where it poses a risk of injury and complexity in setup and storage.
Innovation Solution
A deployable tent design featuring a frame with pivotally mounted base parts and arches that automatically deploy the cap when the frame is unfolded, eliminating the need for manual rod installation by using tension lines in the tent fabric to pivot the cap into position, and a telescopic ladder for easy setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual metal rods are used to deploy the cap, then the cap can be stretched and deployed, but the setup process becomes time-consuming and dangerous
Solution Approach 1:
The cap deployment mechanism uses the tent frame's own motion to automatically deploy the cap. When the base parts unfold from the folded position to the unfolded position, the connecting line becomes tensioned and automatically pulls the cap into its deployed position, eliminating the need for manual intervention and making the system self-servicing.
Solution Approach 2:
The cap is pre-connected to the connecting line that is attached to the frame. Before the frame is deployed, the cap is already positioned and connected, so that when the frame unfolds, the cap deployment action is automatically initiated without requiring separate manual setup steps.
2Ease of operation
If metal rods are used to form canopy tops, then the cap structure is achieved, but the process becomes complex and dangerous when performed at height
Solution Approach 1:
The system automatically deploys the cap using the frame's unfolding motion itself. The tensioning of the connecting line during frame deployment automatically performs the cap deployment function, eliminating complex manual operations and reducing device complexity.
Solution Approach 2:
The invention extracts the cap deployment function from the frame deployment process. Instead of using separate metal rods for cap deployment, the connecting line that is already part of the frame structure is used to automatically deploy the cap, separating the cap deployment action from manual intervention.
3Volume of moving object
If the frame is folded for storage, then the tent is compact, but the cap cannot be deployed for use
Solution Approach 1:
The cap's position is dynamic and automatically changes based on the frame's configuration. When the frame is in the folded position, the cap is in a retracted state; when the frame unfolds, the cap automatically transitions to the deployed position. This dynamic behavior allows the same structure to serve both compact storage and functional deployment needs.
Solution Approach 2:
The cap is pre-positioned and connected to the connecting line in both folded and unfolded states. The capability for cap deployment is prepared in advance by the connection arrangement, allowing automatic deployment whenever the frame is unfolded, without requiring separate setup actions.
4Extent of automation
If the connecting line is tensioned during frame deployment, then the cap is automatically deployed, but force is exerted on the frame
Solution Approach 1:
The cap deployment force is extracted from the frame structure itself. The connecting line, which is already attached to the frame, is used to deploy the cap by utilizing the frame's own unfolding motion, rather than requiring separate deployment mechanisms that would exert additional forces on the frame.
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
Facilitates quick and safe deployment of the tent cap without manual intervention, reducing setup time and risk of injury, while maintaining the cap in position against wind and ensuring secure storage by integrating the frames within the tent structure.
Implementation Method 1
when the frame is brought into the unfolded position, the first and second connecting line portions and the first and second edge portions are tensioned and exert a force on the first frame so as to pivot said first frame relative to the canvas body towards the base plane
Implementation Method 2
said first frame being pivotally articulated relative to the first wall of the tent canvas in at least a first lower portion arranged below said first upper peak, so that the first frame extends under said first cap when the framework is unfolded
