Hand-Pushed Tent Telescoping Pole for Handle Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand pushed tents suffer from misalignment issues between the handle and central pole during the upward pushing process, leading to potential quality risks and uneven support.
Innovation Solution
A hand pushed tent design featuring a central pole composed of telescoping fiberglass rods with a locking structure that includes a positioning ring and hook mechanism, allowing for accurate alignment and stable opening and folding through the retraction and extension of the central pole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a disconnected connection structure is used between the central pole and lower nest, then the tent can be easily assembled and disassembled, but misalignment between the handle and central pole occurs during the upward pushing process
Solution Approach 1:
A guide rail structure is introduced as an intermediary component between the handle and central pole. The guide rail includes a rail body fixed to the lower nest and a sliding block on the central pole that moves along the rail. This intermediary mechanism ensures the central pole remains aligned with the handle during the pushing process while still allowing easy assembly and disassembly of the tent.
2Volume of moving object
If the central pole is made telescopic to improve portability, then the folded size is reduced, but the structural stability during opening and folding is compromised
Solution Approach 1:
The central pole is divided into multiple telescopic sections that can be nested within each other when folded, significantly reducing the folded size. During opening, these segmented sections extend sequentially while being guided by the guide rail structure, ensuring structural stability is maintained throughout the transformation process.
3Length of stationary object
If the central pole is extended for better support, then the support coverage is improved, but the risk of misalignment and quality issues increases
Solution Approach 1:
The guide rail acts as a mediator that constrains the movement of the telescopic central pole sections during extension. This ensures that even as the pole extends to provide better support coverage, the alignment between the handle and central pole is maintained, eliminating quality risks associated with misalignment.

AI summary
A hand pushed tent includes a central lock having a central pole, an upper nest, and a lower nest. An upper end of the central pole is connected to the upper nest. A lower end of the central pole is connected to the lower nest. The central pole is a telescoping pole. A locking structure is provided between the central pole and the lower nest. The central pole has a retracted and extended state. The retracted state of the central pole corresponds to an open state of the hand pushed tent. The locking structure is used to locate the open state of the hand pushed tent. The extended state of the central pole corresponds to a folded state of the hand pushed tent. The lower nest and handle are connected to the upper nest and the canopy cap through the telescoping rod.
