Stroller Frame Linking Mechanism for Compact Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers are not easily foldable, making them inconvenient for storage in small spaces.
Innovation Solution
A stroller frame design featuring a handle, front foot, bottom pipe, and linking mechanism with an engaging device and locking mechanism that allows for identical pivotal directions and non-overlapping joints, enabling easy folding by pivoting the handle, front foot, and bottom pipe through a linking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional stroller structure is used, then the stroller is stable and functional, but it cannot be folded easily and occupies excessive storage space
Solution Approach 1:
The stroller frame is divided into multiple independent segments (handle, front foot, bottom pipe, linking mechanism) that can pivot relative to each other. This segmentation allows the stroller to be folded into a compact configuration while maintaining structural integrity during use, directly resolving the contradiction between storage volume and folding ease.
Solution Approach 2:
The stroller employs a dynamic linking mechanism with pivotal connections that transitions the structure from a rigid extended state to a compact folded state. The pivotal joints enable smooth transformation between configurations, making the folding operation simple while achieving compact storage volume.
2Volume of moving object
If a folding mechanism is added to enable compact storage, then storage space is reduced, but the structure becomes more complex
Solution Approach 1:
The linking mechanism merges multiple functions into a single integrated assembly that connects the handle, front foot, and bottom pipe. This unified structure achieves the folding function without requiring separate complex mechanisms for each connection, thereby reducing overall structural complexity while enabling compact storage.
Solution Approach 2:
The stroller frame components are designed to nest within each other during folding, with the front foot and bottom pipe collapsing inward toward the handle. This nesting arrangement achieves compact storage volume while using a relatively simple hierarchical structure rather than multiple independent mechanisms.
3Ease of operation
If multiple pivotal joints are used to enable folding, then the stroller can be folded easily, but the pivotal joints may overlap causing interference
Solution Approach 1:
Each pivotal joint in the linking mechanism is positioned at a specific location optimized for its function, with non-overlapping arrangements that prevent interference. The handle, front foot, and bottom pipe each have dedicated pivotal connection points that maintain proper spatial separation, ensuring smooth folding operation while preserving structural stability.
