Folding Wagon Canopy Mounting Posts With Detachable Support Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding wagons with removable canopies face limitations in allowing for the complete removal of canopy support rods and lack flexibility in substituting these rods with other useful articles for transport.
Innovation Solution
The folding wagon design incorporates pivotally and detachably connected hollow canopy mounting posts and telescoping rods that can be rotated and removed, allowing for the canopy to be taken off and replaced with other articles, such as cup holders or fishing rod sleeves, by using coupling channels and clips on the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the canopy support rods are permanently carried by the wagon to maintain structural integrity, then the reliability is improved, but the adaptability deteriorates because other useful articles cannot be substituted
Solution Approach 1:
The coupling channel and coupling clip mechanism serves multiple functions: it anchors the canopy support rods during canopy operation, stores the rods when the canopy is removed, and provides attachment points for alternative useful articles. This universal interface resolves the contradiction by allowing the same structural element to serve different purposes based on user needs.
2Adaptability or versatility
If the canopy support rods are made detachable to allow complete removal with the canopy, then the adaptability is improved, but the device complexity increases due to additional coupling mechanisms
Solution Approach 1:
The support system is segmented into the canopy, support rods, and mounting mechanism as separate detachable components. The coupling channel and coupling clip provide simple connection points that allow easy assembly and disassembly without complex fastening systems, resolving the contradiction between removability and simplicity.
3Ease of operation
If the mounting posts are rotated to a horizontal position for storage, then the ease of operation is improved, but the volume occupied increases during the rotation process
Solution Approach 1:
The mounting posts are designed to be rotatable between vertical and horizontal positions, allowing dynamic adaptation to different operational states. During rotation, the posts temporarily occupy intermediate positions, but the mechanism enables easy transition to a compact horizontal storage configuration that minimizes space when the canopy is removed.

AI summary
Disclosed is a folding wagon having a frame that is folded from an expanded configuration at which a variety of articles are carried in a basket to a compact collapsed configuration at which to facilitate the storage or transport of the wagon. A removable canopy is held above the basket by a plurality of hollow mounting posts that are pivotally connected to respective corner brackets mounted on the frame and a corresponding plurality of telescoping canopy support rods that engage the canopy and slide through the hollow mounting posts to adjust the distance between the canopy and the basket. The canopy support rods are disengaged from the canopy to separate the canopy from the wagon, and the pluralities of mounting posts and canopy support rods are rotatable together relative to the wagon frame between a first position standing upwardly from the basket and a second position lying alongside the basket.
