One-Hand Folding Stroller Seat Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stroller designs require both hands and multiple steps to fold, making them cumbersome for storage and transportation.
Innovation Solution
A one-hand folding mechanism with a release handle integrated into the stroller seat that couples with frame hinges, allowing the stroller to transition from a deployed to a collapsed position using a single hand action, featuring a handle spring and slide lock for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional folding mechanisms are used, then the stroller can be folded, but it requires both hands and multiple steps to operate
Solution Approach 1:
The release handle is integrated into the seat assembly, merging the folding release function with the seat structure. This allows the user to fold the stroller by operating a single handle that is already within reach while seated, eliminating the need for multiple hands and steps.
Solution Approach 2:
The release handle serves multiple functions: it acts as both a structural component of the seat assembly and the release mechanism for folding. This multi-functionality reduces the need for separate folding components, simplifying the overall mechanism while maintaining ease of operation.
2Ease of operation
If the release handle is integrated into the seat portion, then it is accessible through the seating area, but it must engage securely to lock the seating area in place
Solution Approach 1:
The release handle acts as an intermediary component that connects the user's manual input to the folding hinges. When operated, it triggers the release of the hinges through the seat assembly, providing both accessibility and secure locking engagement through this intermediate mechanism.
Solution Approach 2:
The seat assembly itself incorporates the release handle and locking mechanism, allowing the seat structure to participate in its own folding and locking operations. This self-service approach ensures that the locking function is integrated into the components already present in the seating area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the stroller to be folded in a single step with one hand, resulting in a more compact and convenient storage and transportation solution compared to traditional designs.
Implementation Method 1
including a handle spring that couples to the release handle such that tension in the handle spring orients the release handle in a first position
