Baby Wagon Hinge Mechanism for Rapid Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby wagons are difficult to fold and unfold, require separate canopy detachment, and have limited baby positioning options, leading to inconvenience and reduced portability and mobility.
Innovation Solution
A baby wagon design featuring a hinge structure for easy folding and unfolding, with a quadrangular main body frame, wheel assembly, and canopy that can be coupled and decoupled without separating, allowing for quick changes between standing and leg chair modes, and easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional locking and unlocking button structure is used with three or four manipulations to unfold the wagon, then the frame structure is stable, but the ease of operation deteriorates and requires multiple steps
Solution Approach 1:
The main body frame is divided into a first main body frame and a second main body frame that can be relatively moved with respect to each other. The side support frame is segmented into multiple sections connected by hinge structures, allowing independent folding of each segment. This segmentation enables the folding function to be achieved through simpler relative movements rather than complex multi-step manipulations.
Solution Approach 2:
The side support frame is designed with hinge structures that enable dynamic folding and unfolding movements. The frame transitions from a static rigid structure to a dynamic adaptable structure that can change its configuration. The hinge connections allow the side support frame to rotate and fold along with the main body frames, providing ease of operation while maintaining structural integrity during use.
2Ease of operation
If the canopy is coupled to the wagon, then the baby is protected from external elements, but the folding and unfolding process becomes more difficult and time-consuming
Solution Approach 1:
The canopy is designed with a dynamic support structure that includes hinge connections and can be folded together with the main body frame. The canopy support frame is configured to move relative to the main body frame, allowing the canopy to be folded along with the frame without requiring separate detachment operations. This dynamic design enables the canopy to transition from an extended protective state to a folded compact state efficiently.
Solution Approach 2:
The folding operation merges the canopy folding with the main body frame folding into a single coordinated action. The canopy support frame is connected to the main body frame through hinge structures that enable synchronized movement. When the main body frame is folded, the canopy automatically folds along with it, combining two separate operations into one unified action that saves time and effort.
3Adaptability or versatility
If the baby seat has a flat structure, then the manufacturing is simple, but the baby comfort and positioning options are limited
Solution Approach 1:
The baby seat is designed with dynamic adjustment capabilities that allow it to change its configuration. The seat includes a backrest that can be adjusted to different angles and positions, and the leg rest can be moved to provide different seating and lying positions. This dynamic design enables the seat to adapt to various baby needs while maintaining a relatively simple base structure that is easy to manufacture.
Solution Approach 2:
The baby seat is designed as a multi-functional component that can serve multiple purposes. By adjusting the backrest and leg rest positions, the same seat structure can provide standing chair mode, leg chair mode, and lying down positions. This universal design allows a single seat structure to fulfill multiple positioning needs without requiring separate specialized seats for each function.
4Ease of manufacture
If the wheel and canopy coupling structure is complicated, then the structural stability is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The coupling structure is segmented into modular components with standardized connection interfaces. The wheel assembly and canopy support are divided into separate modules that can be independently manufactured and then assembled through simple coupling operations. This segmentation allows each component to be optimized for its specific function while maintaining simple assembly through standardized connectors.

AI summary
A baby wagon with improved ease of use has a folding structure which is stably configured, and thus damages to frames, such as twisting or bending of the frames, can be prevented, such that the baby wagon is stably folded and unfolded, the use of the baby wagon is convenient while durability of the baby wagon is excellent, and comfort of a baby can be maintained even when the baby is in the baby wagon for a long time. The frames are manufactured so as to be easily folded even in the state in which the canopy is coupled thereto, whereby the baby wagon is unfolded and folded within a short time, such that that portability and mobility of the baby wagon are excellent, and such that detachment and coupling of a canopy and a wheel assembly are easily performed.
