Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional folding wagons require the removal of canopies before folding from the in-use configuration to the storage configuration, which is inconvenient and inefficient.

Innovation Solution

A foldable wagon design where the canopy assembly is constructed to rotate from an in-use configuration to a storage configuration without needing to be removed, utilizing rotatable canopy support frames and a slidable canopy connection mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the canopy is permanently attached to the wagon, then the wagon structure is simplified and more reliable, but the wagon cannot be folded for storage

Engineering Contradiction:

Improvecanopy attachment reliabilityVSAvoidwagon foldability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The canopy support frames are designed to be rotatable relative to the wagon frame, allowing the canopy to transition between an extended position (when the wagon is in use) and a retracted position (when the wagon is folded for storage). This dynamic mechanism enables the wagon to be folded without removing the canopy, resolving the contradiction between permanent attachment reliability and foldability versatility

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the canopy is made removable, then the wagon can be folded for storage, but the canopy must be removed before folding which is inconvenient and time-consuming

Engineering Contradiction:

Improvewagon foldabilityVSAvoidtime to prepare for storage

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The rotatable canopy support frames allow the canopy to remain attached while automatically accommodating the folded configuration. The user simply rotates the support frames to retract the canopy, eliminating the time-consuming process of completely removing and storing the canopy separately

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the canopy support frames are extended beyond the wagon frame, then the canopy can rotate without interference, but the wagon width increases

Engineering Contradiction:

Improvecanopy rotation capabilityVSAvoidwagon width

Core Design Contradiction:

Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The canopy support frames utilize the vertical dimension by extending upward beyond the wagon frame, providing the necessary rotation space without significantly increasing the horizontal width. This allows the canopy to rotate freely while maintaining a compact wagon profile when folded

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A wagon for carrying children or other articles comprising a canopy. The wagon has a canopy to provide shade and protection to the occupants and/or other contents of the wagon and the canopy may be folded from an in-use configuration to a storage configuration. If the wagon is a foldable wagon, the canopy may remain on the wagon during and after the folding of the wagon.
