Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic waste gates in turbochargers face overheating issues due to direct heat transfer from exhaust gases, which can lead to module breakdown or errors.
Innovation Solution
A support bracket system with coupling protrusions and an insulator is used to connect the waste gate module to the turbocharger housing, preventing heat transfer and stabilizing the module with multiple coupling points while allowing for precise installation and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the actuation module is disposed close to the turbo charger to control the waste gate, then the control accuracy and response time are improved, but the temperature of the actuation module exceeds the allowable temperature due to heat transfer from exhaust gas
Solution Approach 1:
The support bracket is divided into multiple sections with coupling protrusions at different locations, creating thermal zones that separate the hot exhaust side from the cooler actuation module side while maintaining structural connectivity
Solution Approach 2:
The support bracket acts as an intermediary thermal barrier between the exhaust gas and the actuation module, using its structural design with coupling protrusions to limit heat transfer while maintaining mechanical support and control functionality
2Device complexity
If the support bracket directly connects the waste gate module to the turbocharger housing, then the structural simplicity is improved, but the heat transfer to the waste gate module increases causing overheating
Solution Approach 1:
The support bracket incorporates multiple coupling protrusions that segment the connection interface, creating thermal breaks while maintaining structural support. This segmented design limits heat transfer paths without significantly increasing overall structural complexity
Solution Approach 2:
The coupling protrusions are strategically positioned to create local thermal barriers at critical heat transfer points, providing targeted thermal management where it is most needed while maintaining overall structural simplicity
3Stability of the object's composition
If multiple coupling protrusions are formed on the support bracket, then the stabilization and vibration distribution are improved, but the manufacturing complexity increases
Solution Approach 1:
The support bracket is designed with multiple coupling protrusions that segment the mounting interface, distributing mechanical loads and vibrations across multiple points. This segmentation enhances stability while the protrusions can be manufactured using standard machining operations
Solution Approach 2:
The coupling protrusions serve multiple functions simultaneously: mechanical support, vibration distribution, and thermal barrier creation. This multi-functionality achieves stabilization benefits without proportionally increasing manufacturing complexity
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 limits heat transfer to the waste gate module, preventing overheating and ensuring stable operation by distributing vibrations and loads uniformly across the coupling protrusions and using an insulator for additional insulation and anti-vibration.
Implementation Method 1
An insulator for insulation or anti-vibration may be further provided between faces of the coupling protrusion and the waste gate module which are coupled

AI summary
An apparatus for supporting a waste gate module includes a support bracket connecting the waste gate module and a turbocharger housing, and a coupling protrusion formed on a face of the support bracket and that faces the waste gate module, where the coupling protrusion has an end coupled to the waste gate module.
