Stroller Wheel Device Shock Absorption Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stroller shock-absorbing mechanisms have complex structures, leading to increased manufacturing costs without effectively facilitating smooth movement on uneven road surfaces.
Innovation Solution
A stroller wheel device with a simple shock-absorbing mechanism comprising a wheel, a frame-connecting member, a wheel-connecting arm, and a resilient member, where the arm's rotation compresses the resilient member between pressing portions to absorb shock, allowing for smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional shock-absorbing mechanism is used, then shock absorption function is provided, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent combines the shock-absorbing mechanism with the wheel-connecting structure by integrating the resilient member directly into the connection between the frame-connecting member and wheel-connecting arm. This merging eliminates the need for separate shock-absorbing components while maintaining the shock absorption function, thereby simplifying the overall structure and reducing manufacturing cost.
Solution Approach 2:
The wheel-connecting arm serves multiple functions: it connects the wheel to the frame, enables wheel rotation, and simultaneously acts as a shock-absorbing component through the integrated resilient member. This multi-functionality reduces the number of separate components needed, simplifying the structure while maintaining reliable shock absorption.
2Reliability
If a conventional shock-absorbing mechanism is used, then shock absorption function is provided, but manufacturing cost increases
Solution Approach 1:
By merging the shock-absorbing function into the existing wheel-connecting structure, the patent reduces the total number of components that need to be manufactured and assembled. This integration lowers manufacturing complexity and cost while maintaining the shock absorption function through the resilient member.
Solution Approach 2:
The wheel-connecting arm structure serves itself by incorporating the resilient member directly into its design, eliminating the need for separate shock-absorbing components. This self-service approach reduces manufacturing steps and assembly operations, thereby lowering production costs while maintaining functional reliability.
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 solution provides effective shock absorption, reducing the complexity and cost of manufacturing while ensuring smooth stroller movement on uneven surfaces by using a straightforward design that compresses a resilient member between pressing portions.
Implementation Method 1
a resilient member disposed between and abutting against the first and second pressing portions such that, when the wheel-connecting arm rotates relative to the frame-connecting member, the first and second pressing portions move toward each other to compress the resilient member

AI summary
A stroller wheel device includes a wheel, a frame-connecting member, a wheel-connecting arm, and a resilient member. The frame-connecting member includes at least one first pressing portion. The wheel-connecting arm includes upper and lower ends connected respectively and pivotally to the frame-connecting member and the wheel, and at least one second pressing portion spaced apart from the first pressing portion. The resilient member is disposed between and abuts against the first and second pressing portions. When the wheel-connecting arm rotates relative to the frame-connecting member, the first and second pressing portions move toward each other to compress the resilient member.
