Drag Chain Side Part Elastic Damping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drag chain systems face increased manufacturing costs and noise emission due to the need for additional damping elements and higher force application to pivot chain links, which complicates the manufacturing process and affects system efficiency.
Innovation Solution
A side part of a drag chain system with a first region and a second region featuring stop faces and an elastic element secured on one side, allowing for reduced noise by bending the elastic element before stop faces contact, enabling adjustable damping and easier manufacturing through a simple design and two-component injection method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If additional damping elements are introduced into recesses to reduce noise emission, then noise emission is reduced, but manufacturing expenditure increases
Solution Approach 1:
The elastic element is integrated directly into the side part structure, combining the damping function with the structural component. This eliminates the need for separate damping elements and recesses, reducing manufacturing complexity while maintaining noise reduction functionality
Solution Approach 2:
The side part structure itself provides the damping function through its elastic element, making the component self-sufficient for noise reduction without requiring additional external damping elements or modifications
2Object-affected harmful factors
If chain links are provided with deformable areas and wall regions that extend into recesses under elastic deformation, then noise emission is reduced, but increased force is necessary to transfer chain links into extended position
Solution Approach 1:
The harmful impact force is extracted and redirected onto the elastic element, which absorbs the shock through deformation. This prevents the impact force from being transmitted to the chain link pivoting mechanism, avoiding the need for increased force application
3Manufacturing precision
If stop faces are provided to determine radius of curvature, then guidance accuracy is improved, but noise is generated when stop faces impact against one another during fast movement
Solution Approach 1:
The elastic element acts as an intermediary between the stop and the stop face impact. It absorbs the impact energy through elastic deformation, preventing direct contact and noise generation between stop faces while maintaining the guidance function
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 reduces noise emission and manufacturing complexity by using an elastic element that absorbs impact, allowing for adjustable damping and increased braking efficiency with varying swiveling angles, while maintaining a straightforward manufacturing process.
Implementation Method 1
the stop rests on the elastic element before the stop faces of the two side parts lie against one another. The at least one element and the stop are thereby preferably adjusted to one another in such a way that by bending the elastic element, the pivoting movement of the two side parts is reduced.
