Foldable Stroller Wagon Handle Nesting and Soft Goods Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stroller wagons with both pushing and pulling modes do not compactly store handles, leading to increased footprint and untidy appearance due to hanging handles and bulky soft goods attachments.
Innovation Solution
A foldable wagon assembly with pivotally attached handles that nest within the frame and a secure, sleek attachment system for soft goods using slots and slots for securing soft goods assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handles are left to hang or lay on the ground when not in use, then the stroller wagon maintains accessibility to handles, but the footprint of the stroller wagon increases
Solution Approach 1:
The handle is configured to nest within the frame structure when not in use, with the handle pivotally attached to allow it to be positioned inside the frame's receiving area. This nesting mechanism reduces the overall footprint of the stroller wagon while maintaining handle accessibility when needed, as the handle can be easily deployed from its nested position within the frame.
2Reliability
If soft goods attachments wrap around the wagon frame with fasteners, then the soft goods are securely attached, but the appearance becomes untidy or bulky
Solution Approach 1:
The attachment mechanism for soft goods is extracted from the traditional wrap-around fastener design. Instead, the soft goods assembly is received within a recess or compartment of the frame structure, eliminating the need for external fasteners and wrap-around configurations. This extraction of the attachment mechanism from the frame surface creates a cleaner, more streamlined appearance while maintaining secure attachment through the integrated recess design.
3Ease of manufacture
If hook and loop type fasteners are used for soft goods attachments, then the attachment is simple and secure, but the fasteners accumulate dirt or debris and degrade over time
Solution Approach 1:
The hook and loop fastener system is completely extracted from the attachment design. Instead, the soft goods assembly is secured through a recess or compartment integration with the frame, eliminating exposed fasteners that would accumulate dirt and debris. This extraction of the fastening mechanism from the external surface prevents contamination while maintaining secure attachment through the structural recess design.
4Ease of operation
If the push handle is made telescoping and lengthened, then the handle provides adequate reach for pushing, but the overall size of the wagon assembly increases
Solution Approach 1:
The push handle is designed with telescoping capability, allowing it to dynamically adjust its length. When not in use, the handle is retracted to minimize the overall size of the wagon assembly. When pushing is required, the handle can be extended to provide adequate reach. This dynamic length adjustment resolves the contradiction between providing sufficient pushing reach and maintaining a compact overall size.

AI summary
A foldable wagon assembly is disclosed herein including multiple features. In one aspect, a push handle is provided that includes pivoting connections located inward from a longitudinally outermost edge of a frame of the wagon. In another aspect, an upper end of the frame includes at least one slot for securely attaching a soft goods enclosure to the wagon. A pull handle is also provided that can be securely attached in a generally upright position via a retention clip formed on the frame of the wagon.
