Foldable Stroller Protection Between Folding Frame Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles with protective components, such as strollers or wagons, are cumbersome to fold and occupy large spaces when folded, making them inconvenient for storage.
Innovation Solution
A foldable vehicle design featuring a bottom bracket, a push rod frame rotatably connected to the bottom bracket, and a protective assembly between them, allowing for a compact folding mechanism that includes a protective assembly that folds between the push rod frame and the bottom bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If protective components are added to the vehicle, then protection against sunlight, rain, or snow is improved, but the structure becomes complicated and folding is inhibited
Solution Approach 1:
The protective components are divided into multiple segments that can fold independently. The protective cover includes a first protective component and a second protective component that can be folded separately, allowing the structure to remain protected while enabling compact folding configuration.
Solution Approach 2:
The protective components are designed to nest within the vehicle structure when folded. The first and second protective components can be positioned inside the vehicle body or along the folding joints, reducing the overall folded dimensions while maintaining protection functionality.
2Object-affected harmful factors
If protective components are integrated into the vehicle, then protection functionality is improved, but the vehicle size after folding increases and occupies large space
Solution Approach 1:
The protective components are designed with dynamic folding capabilities, allowing them to transition between extended protective positions and retracted storage positions. The protective components can be folded along with the vehicle frame, adapting to the changing geometry during folding operation.
Solution Approach 2:
The protective components utilize the vertical dimension and internal space of the vehicle structure for storage during folding. Rather than extending horizontally, the protective components are positioned to fold upward or inward, reducing the horizontal footprint of the folded vehicle.
3Ease of operation
If protective components are made removable, then folding complexity is reduced, but user convenience deteriorates due to removal and storage requirements
Solution Approach 1:
The protective components are merged with the vehicle frame through integrated folding joints and connection mechanisms. The protective components and frame move as a unified structure during folding, eliminating the need for separate removal and storage operations while maintaining operational simplicity.
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
The design enables a sturdy vehicle that can be folded into a smaller configuration, accommodating items while occupying minimal storage space, with protective features that remain integrated during folding.

AI summary
A foldable vehicle or stroller is provided. The apparatus includes a bottom bracket forming a vehicle base, a push rod bracket rotatably connected to the bottom bracket, and a protective assembly located on one side of the push rod bracket between the push rod bracket and the bottom bracket. The foldable vehicle is in an unfolded state, remote ends of the push rod bracket and the bottom bracket are positioned apart, proximal ends of the push rod bracket and the bottom bracket join at a rotation element, and an accommodating space is formed between the bottom bracket, the protective assembly and the push rod bracket. When the foldable vehicle is in a folded state, remote ends of the push rod bracket and the bottom bracket are positioned proximally and the protective assembly is positioned at least partially between the push rod bracket and the bottom bracket.
