Heat-Protected Urea Tank Bracket Near Vehicle Exhaust Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for protecting the urea tank's fixing leg from overheating due to proximity to exhaust lines often result in discontinuities with thermal screens, leading to inadequate heat protection and potential failure of the fixing leg's function.
Innovation Solution
Incorporating a thermal protection layer into the fixing leg itself, which can be either a distinct component or an integral part of the leg's material, to act as a direct screen between the leg and the exhaust line, preventing overheating without the need for additional thermal screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a heat shield is placed between the mounting bracket and the exhaust pipe, then the mounting bracket is protected from heat, but the tank's mounting bracket and the tank itself remain exposed to heat due to discontinuities at attachment points
Solution Approach 1:
The heat shield function is merged with the mounting bracket by integrating a thermal protection layer directly onto the bracket. This eliminates the discontinuities that occur when a separate heat shield is used, as the protection is now continuous and follows the exact geometry of the bracket including all attachment points to the tank.
Solution Approach 2:
The mounting bracket is transformed into a composite structure by adding a thermal protection layer (such as ceramic coating or insulating material) to the metal bracket. This composite construction provides both the structural strength of metal and the thermal insulation properties of the protective layer, solving the heat exposure problem while maintaining bracket integrity.
2Object-affected harmful factors
If a separate heat shield is installed between the mounting bracket and exhaust system, then heat protection is provided, but device complexity and installation difficulty increase
Solution Approach 1:
The mounting bracket and heat shield functions are combined into a single integrated component. The thermal protection layer is applied directly to the bracket, eliminating the need for a separate heat shield component and its associated mounting hardware, thereby reducing device complexity.
Solution Approach 2:
The mounting bracket is given multiple functions: it provides structural support for the tank and simultaneously provides thermal protection through its integrated thermal protection layer. This multi-functionality eliminates the need for separate protective components.
3Object-affected harmful factors
If a separate heat shield is used to protect the mounting bracket, then heat protection is achieved, but manufacturing costs and installation time increase
Solution Approach 1:
The thermal protection layer is applied to the mounting bracket in advance during bracket manufacturing, before the bracket is installed on the vehicle. This preliminary action eliminates the need for separate heat shield installation steps during vehicle assembly, thereby increasing productivity.
Solution Approach 2:
The manufacturing of the thermal protection layer is merged with the bracket production process. By applying the protective layer during bracket fabrication rather than as a separate installation step, the overall manufacturing time is reduced and assembly productivity is improved.
