Stroller Covering Component Elastic Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers pose a risk of infants' fingers being clipped by engaging components when assembling with infant safety seats, as they require an opening for engagement, which is not safely designed.
Innovation Solution
A stroller design featuring a covering component with a first portion and a second portion, where the first portion has a higher elastic coefficient than the second, allowing it to be clamped between engaging portions without needing an opening, using materials like PET and PU or polyester and spandex for enhanced elasticity and damage resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an opening is formed on the covering component to expose engaging components for assembly between stroller and infant safety seat, then assembly function is enabled, but infant's fingers may be clipped by the engaging components
Solution Approach 1:
The patent removes the opening from the covering component entirely. Instead of having an opening to expose engaging components, the covering component is designed to be elastically deformable so that it can be pushed through the engaging components during assembly, eliminating the hazard of finger clipping while maintaining assembly functionality
Solution Approach 2:
The patent changes the elastic coefficient parameter of the covering component. The covering component is designed with an elastic coefficient that allows it to be deformed during assembly (pushed through engaging components) and then return to its original shape, enabling assembly without openings while preventing finger clipping
2Strength
If the covering component is made rigid to resist damage during folding and assembly, then damage resistance is improved, but it cannot be deformed to enable engagement between engaging portions
Solution Approach 1:
The patent applies local quality by creating a covering component with non-uniform elastic properties. The first portion has a higher elastic coefficient than the second portion, allowing different regions to serve different functions: the first portion deforms more easily to enable engagement, while the second portion provides structural support and damage resistance
Solution Approach 2:
The patent uses composite material structure with multiple layers having different elastic coefficients. The covering component comprises a first portion and a second portion with different elastic properties, combining the benefits of deformability (first portion) and strength/damage resistance (second portion) in a single integrated component
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
Prevents finger clipping by eliminating the need for an opening in the covering component and enhances the stroller's ability to resist damage during folding and assembly.
Implementation Method 1
an elastic coefficient of the first portion is greater than an elastic coefficient of the second portion, and the first portion is clamped between the first engaging portion and the second engaging portion
Implementation Method 2
the first portion is extended to an edge of the assembly chamber, so as to improve ability of resisting damage of the first portion

AI summary
A stroller for assembling with an infant safety seat having a first engaging portion. The stroller includes a second engaging portion and a covering component. The second engaging portion is for engaging with the first engaging portion; the covering component includes a first portion and a second portion. The first portion is for covering the second engaging portion. The second portion is surrounding the first portion, and the first portion is clamped between the first engaging portion and the second engaging portion the infant safety seat is assembled with the stroller via the first engaging portion being engaged with the second engaging portion. It is not needed to form an opening on the covering component to implement engagement between the stroller and the infant safety seat, so as to solve a problem of fingers of an infant on the stroller being clipped by the opening.
