Solution Overview

Problem

Existing folding tents require manual adjustment to deploy the eave pole, making them inconvenient to use.

Innovation Solution

A tent framework with an extension pole divided into three sections, where the first section extends outward and is hinged to an auxiliary pole, allowing for automatic deployment and stable locking in the unfolded state, and compact folding in the stored state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the eave pole is manually flipped after unfolding the upright poles, tent top poles and diagonal brace, then the eave pole can be positioned parallel to the tent top poles, but this manual adjustment process makes the tent inconvenient to use

Engineering Contradiction:

Improveconvenience of eave pole deploymentVSAvoidtime required for manual adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The extension pole is designed to automatically flip and extend outward when the support poles are separated outward to unfold the tent. The hinged connection between the extension pole and auxiliary pole, combined with the obtuse angle arrangement of the pole sections, enables the extension pole to self-deploy without manual intervention, making the system serve itself during the unfolding process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The extension pole is designed with hinged connections and obtuse angle joints that allow it to dynamically change its configuration during deployment. The pole transitions from a folded state to an extended state through controlled mechanical movement, enabling automatic flipping and positioning parallel to the tent top poles when the support poles are separated.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the extension pole is divided into three sections with hinged connections, then the structure becomes more flexible for automatic deployment, but the device complexity increases

Engineering Contradiction:

Improveflexibility of extension pole deploymentVSAvoidcomplexity of three-section hinged structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The extension pole is divided into three distinct pole sections (first, second, and third pole sections) connected by hinged joints. This segmentation allows each section to move independently, enabling the pole to flex and adapt to different positions during deployment while maintaining structural integrity through the hinged connections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The three-section extension pole is designed to fold compactly when not in use, with the pole sections nested or folded together to minimize space occupation. The hinged connections enable the pole to transition between an extended configuration for deployment and a compact folded configuration for storage, reducing the overall footprint when retracted.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

The invention discloses a tent framework and a tent, where the tent framework includes a tent framework main body composed of support poles, tent top poles, a top connector, tent side poles, an auxiliary pole, an extension seat and a sliding seat, as well as an extension pole with an inner end hinged to the auxiliary pole and penetratingly arranged in the extension seat. In an unfolded state, the extension pole is arranged to extend outward to extend out of the tent framework main body to support corners of a tarpaulin; and in a folded state, the extension pole is folded and accommodated in the tent framework main body, thereby not increasing the folded size.
