Stroller Suspension Block with Diagonal Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers lack a suspension system to absorb both vertical and horizontal impact forces, potentially causing discomfort and danger to children when navigating obstacles.
Innovation Solution
A suspension system for strollers featuring a suspension block with a diagonal aperture and a spring retention mechanism that allows the axle to move horizontally and vertically, absorbing impact forces through a spring retainer and chamber, providing protection against both vertical and horizontal impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional stroller without suspension system is used, then the structure is simple and easy to manufacture, but impact forces from obstacles are directly transferred to the child causing discomfort and danger
Solution Approach 1:
The suspension system divides the wheel assembly into separable components: a wheel, an axle that can move independently, and a frame. The axle is positioned in an aperture that allows it to move horizontally and vertically relative to the frame, creating distinct functional segments that can absorb impact independently
Solution Approach 2:
The axle serves as an intermediary element between the wheel and the frame. It absorbs impact forces through its movement within the aperture, mediating the transfer of forces between the wheel (which contacts obstacles) and the frame (which supports the child), thereby reducing direct impact transmission
2Adaptability or versatility
If a suspension system with diagonal aperture is implemented, then both vertical and horizontal impact forces are absorbed, but the manufacturing precision and alignment requirements increase
Solution Approach 1:
The aperture is designed with an asymmetric diagonal orientation rather than vertical or horizontal alignment. This asymmetric angle (e.g., 30 degrees from vertical) enables the system to absorb impact forces from multiple directions simultaneously, providing versatile protection against both vertical drops and horizontal obstacles
Solution Approach 2:
The diagonal aperture configuration provides multi-functional impact absorption capability. A single aperture design handles both vertical impacts (when the stroller encounters bumps or drops) and horizontal impacts (when the wheel strikes obstacles like curbs or rocks), eliminating the need for separate suspension mechanisms for different impact directions
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 system effectively reduces the transfer of impact forces to the child by allowing the wheel and axle to move relative to the frame, absorbing and dissipating forces in both directions, thereby enhancing safety and comfort.
Implementation Method 1
a spring retainer and chamber configured and capable of absorbing an impact force applied to the wheel

AI summary
Disclosed herein are aspects and embodiments of a suspension system for a stroller. In one example, a stroller includes a frame member (110) and a suspension block (130) coupled to the frame member. The suspension block (130) includes a body and a suspension mechanism coupled to the body and disposed at an acute angle from a vertical axis of the body. The stroller further includes a wheel (120) mounted on an axle (150) coupled to the suspension block (130).
