Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional charge air lines in vehicles face challenges with mechanical stability and resonance vibrations, particularly due to high dead weight in metal lines and instability in plastic lines.
Innovation Solution
A fluid line comprising a plastic tube with a surrounding plastic mesh that is inseparably connected to dampen resonance vibrations, allowing for reduced weight and enhanced mechanical stability, with the mesh optionally formed in one piece with the tube or welded on, and featuring a design that optimizes stabilization through strategically placed grid sections and side struts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal pipe is used, then mechanical stability is improved, but weight increases
Solution Approach 1:
The invention uses a composite structure consisting of a plastic tube combined with a plastic grid (cross-bracing). This composite design provides mechanical stability comparable to metal pipes while maintaining the weight advantages of plastic materials, effectively resolving the contradiction between strength and weight.
Solution Approach 2:
The plastic grid is strategically positioned at specific locations along the plastic tube where mechanical support is most needed. This localized reinforcement approach provides adequate mechanical stability without unnecessarily increasing weight throughout the entire pipe structure.
2Weight of moving object
If plastic pipe is used, then weight is reduced, but resonance vibrations increase
Solution Approach 1:
The plastic grid structure acts as a vibration damping mechanism that disrupts resonant vibrations in the plastic tube. The cross-bracing creates multiple structural nodes that break up vibration patterns, effectively reducing harmful resonance while maintaining the lightweight plastic construction.
Solution Approach 2:
The grid is placed at specific sections of the tube where resonant vibrations are most problematic, providing targeted vibration damping without adding unnecessary weight to the entire pipe system.
3Strength
If pipe thickness is increased, then mechanical stability is improved, but weight increases
Solution Approach 1:
Instead of increasing the thickness of the plastic tube wall, the invention uses an external plastic grid structure to provide the necessary mechanical stability. This approach maintains the lightweight advantage of thin-walled plastic tubes while achieving the required strength through the composite grid-tube structure.
Solution Approach 2:
The solution moves from a one-dimensional thickness increase to a two-dimensional external reinforcement structure. The plastic grid adds structural strength in the radial and circumferential directions without requiring increased wall thickness, thereby avoiding weight penalties.
