Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exhaust gas system components for commercial vehicles, due to their design and weight, experience unwanted rotation during travel, leading to instability and potential damage.
Innovation Solution
The exhaust gas system elements are supported in multiple frames connected by stiffening struts, with an inner and outer jacket providing insulation and additional structural support, reducing rotation risk without increasing weight, and incorporating heat insulation and acoustic absorption materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the exhaust gas system component uses a heavy design for commercial vehicles, then the structural strength is improved, but the component experiences unwanted rotation during travel due to accelerations
Solution Approach 1:
The exhaust gas system component is divided into multiple exhaust gas system elements that are mutually connected and supported in separate frames. This segmentation allows each element to be independently positioned and stabilized, reducing unwanted rotation while maintaining overall structural strength.
Solution Approach 2:
The patent introduces a spatial dimension by supporting exhaust gas system elements in frames spaced apart from one another and connecting them with struts. This three-dimensional arrangement creates a stable geometric structure that resists rotation during vehicle travel without requiring excessive weight.
2Stability of the object's composition
If connection struts and multiple frames are added to reduce rotation, then the structural stability is improved, but the weight of the component increases
Solution Approach 1:
Instead of uniformly increasing the weight of the entire exhaust gas system component, the patent applies stabilization measures locally by using discrete connection struts between specific frames. This targeted approach provides necessary structural stability only where needed, minimizing overall weight increase.
3Stability of the object's composition
If the exhaust gas system elements are rigidly connected to reduce rotation, then the structural stability is improved, but the welding deformation and assembly complexity increase
Solution Approach 1:
The exhaust gas system is divided into modular elements supported in separate frames that are connected by struts. This segmentation allows for simpler assembly compared to a fully rigid structure, as each module can be positioned and connected independently, reducing welding deformation and assembly complexity.
