Elastic Telescopic Ram for Tent Eave Tarpaulin Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tent designs face issues with tarpaulin damage and poor appearance due to the eave tarpaulin being tightly stretched and dragged during folding and unfolding, leading to potential tears and a baggy appearance.
Innovation Solution
An elastic telescopic ram is placed between the supporting rods on the tent, equipped with a spring and cloth bushing system that allows for adjustable support and retraction of the eave tarpaulin, preventing damage and maintaining a tight, non-baggy state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the eave tarpaulin is tightly stretched and connected between the ram and supporting rods, then the tarpaulin provides good support and structure, but the tarpaulin is easily dragged and torn during folding and unfolding, reducing its lifetime
Solution Approach 1:
The patent applies the dynamics principle by making the ram telescopic rather than fixed. The ram can dynamically adjust its length during folding and unfolding operations, extending to provide support when needed and retracting to reduce stress on the tarpaulin during movement. This dynamic adjustment resolves the contradiction between maintaining strong support and preventing damage during operation.
2Shape
If the eave tarpaulin is tightly stretched to maintain appearance, then the tarpaulin looks neat and non-baggy, but the tarpaulin is prone to rupture and damage during tent folding and unfolding
Solution Approach 1:
The telescopic ram provides dynamic support that adapts to the tent's state. When the tent is unfolded, the ram extends to keep the tarpaulin taut and maintain a neat appearance. When folding begins, the ram retracts automatically, allowing the tarpaulin to move without excessive tension that would cause rupture. This dynamic adjustment eliminates the need to choose between appearance and damage prevention.
3Stability of the object's composition
If the ram is fixed length to provide stable support, then the eave tarpaulin remains taut, but the tarpaulin cannot accommodate the movement during folding and unfolding without being dragged and torn
Solution Approach 1:
The patent transforms the fixed ram into a telescopic mechanism that can adjust its length. During normal use, the ram maintains a fixed extended position to keep the tarpaulin taut and stable. During folding and unfolding operations, the ram telescopes to accommodate the movement, allowing easy operation without dragging or tearing the tarpaulin. This dynamic capability resolves the contradiction between stability and ease of operation.
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
The elastic telescopic ram system prevents tarpaulin damage and maintains a tight, non-baggy appearance by allowing for automatic adjustments during folding and unfolding, extending the lifespan of the tent fabric.
Implementation Method 1
An elastic body is matched on the ram to form the elastic telescopic rod
Implementation Method 2
The elastic body is a spring abutting against the front end of the ram
