Jointed Traction Bar With Damping for Child Trailer Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traction transmission devices, such as traction bars, fail to effectively absorb or reduce vibrations between a person pulling a child trailer and the trailer, leading to unwanted and potentially dangerous movements, and often require complex or expensive materials and designs that are susceptible to damage or error.
Innovation Solution
A traction transmission device comprising two portions connected via a joint that allows relative pivotal movement, with a damping device integrated into the connecting means to absorb and limit vibrations, providing a compact and reliable solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a flexible line surrounded by rigid links is used to dampen movements, then vibration damping is improved, but device complexity and installation space requirements increase
Solution Approach 1:
The traction bar is divided into two separate portions (first portion and second portion) that are connected through a joint, allowing each portion to be simpler in structure while collectively achieving the damping function through their relative movement
Solution Approach 2:
A joint is introduced as an intermediary connection between the two portions of the traction bar. This joint enables relative pivotal movement that dampens vibrations without requiring complex flexible lines or multiple movable links
2Object-affected harmful factors
If a curved flexible traction bar is used to dampen vibrations, then vibration damping is improved, but manufacturing complexity and material cost increase
Solution Approach 1:
The traction bar is segmented into two portions connected by a joint, allowing each portion to be manufactured as a simpler rigid component rather than requiring a complex curved flexible design
Solution Approach 2:
The flexible curved bar design is replaced with a rigid bar system that uses a mechanical joint to achieve the same vibration damping effect through controlled pivotal movement
3Object-affected harmful factors
If a damping element is added to the connecting means, then vibration damping is improved, but reliability decreases due to potential damage under unlimited load
Solution Approach 1:
The joint connecting the two portions is designed to allow dynamic relative pivotal movement during operation, enabling the system to adapt to varying loads and movements while maintaining connection integrity
Solution Approach 2:
The degree of freedom of the connection is changed by introducing a joint that permits controlled pivotal movement, transforming the rigid connection into a flexible one that can accommodate load variations without damage
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 effectively decouples movements between the person and the child trailer, ensuring safe and comfortable traction by allowing relative pivotal movement while damping vibrations, resulting in a stable and cost-effective design.
Implementation Method 1
the second ends (of the first and second portions) are connected via a connecting means, preferably comprising a joint, in such a manner that a relative movement, preferably a relative pivotal movement, is allowed between the second ends (of the first and second portions)
Implementation Method 2
with a damping device integrated into the connecting means to absorb and limit vibrations
