Baby Wagon Folding Frame with Dual Brakes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby wagons are bulky when folded, making them difficult to fit in small cars, and their frames are not securely fixed, which can lead to damage and safety issues, while brakes are only mounted at the rear, complicating movement and stopping.
Innovation Solution
A baby wagon with a folding body frame that can be easily unfolded and refolded, featuring a rectangular parallelepiped shape with snap fasteners and Velcro for secure assembly, detachable canopy, and brakes at both front and rear for improved maneuverability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the baby wagon is designed with an integrated structure using welding or riveting, then the structural strength is improved, but the volume when folded becomes large and portability is reduced
Solution Approach 1:
The frame is divided into multiple detachable sections that can be separated and folded independently. The main frame includes a front section and a rear section that can be detached from each other, allowing the wagon to be folded into a compact configuration that fits in small car trunks while maintaining structural integrity when assembled.
Solution Approach 2:
The folding mechanism allows frame sections to be nested within each other when folded, minimizing the overall volume. The seat unit and canopy can be collapsed and stored within the frame structure, creating a compact nested configuration for easy portability.
2Ease of operation
If the frames are not completely fixed in the folded state, then the ease of folding is improved, but the frames may be damaged and the caregiver may be injured
Solution Approach 1:
The frame sections are designed with pre-positioned connection points and alignment features that guide proper assembly. Quick-connect mechanisms with built-in alignment guides ensure that frames are correctly positioned before final locking, making the folding and unfolding process easy while ensuring reliable fixation.
Solution Approach 2:
The connection mechanisms automatically lock into place when frames are properly assembled, providing self-verifying fixation. The design includes visual or tactile indicators that show when frames are correctly connected and locked, ensuring reliability without requiring complex manual securing steps.
3Device complexity
If the brake is mounted only at the rear, then the device complexity is reduced, but the ease of operation is worsened when moving or stopping the wagon in opposite directions
Solution Approach 1:
Brake mechanisms are integrated into both the front and rear wheel assemblies, allowing the caregiver to stop the wagon from either the front or rear handle position. The brake systems are designed with similar simple mechanisms at both locations, maintaining low complexity while significantly improving operational flexibility and ease of use.
4Adaptability or versatility
If the baby wagon is designed to accommodate two or more babies, then the versatility is improved, but the volume when folded becomes large
Solution Approach 1:
The seat units are designed to be dynamically configurable, allowing them to be attached, detached, or repositioned along the frame. The frame includes adjustable mounting points that accommodate different seat configurations for one or multiple babies. When folded, the seats can be detached or collapsed to minimize volume, providing versatility during use and compactness for storage.

AI summary
Provided herein is a baby wagon with improved ease of use configured such that the volume of the bulky body of the baby wagon is minimized in a wagon folding mode, whereby it is possible to easily put the baby wagon in the trunk of a small-sized car, such that frames are completely fixed in the wagon folding mode, whereby it is possible to prevent damage to the frames due to protrusion of the frames when the baby wagon shakes or is laid down, and such that brakes are mounted to the front and rear parts of the baby wagon in order to easily move or stop the baby wagon in opposite directions, whereby it is possible to improve the ease of use. The baby wagon includes a folding type body frame, a wagon wheel unit, a seat unit, and a canopy.
