Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing gas heat pump systems face issues with reduced engine output due to low air supply pressure, increased complexity and weight from separate components, vibration-induced damage, and inefficient heat collection in the exhaust gas heat exchanger, leading to performance and durability concerns.
Innovation Solution
A gas heat pump system design that integrates a turbocharger and exhaust gas heat exchanger directly with the engine, reduces component separation, and optimizes the flow path to increase pressure and density of the mixed gas, while ensuring the exhaust gas heat exchanger is inclined to prevent water condensation and corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a turbocharger is added to increase air supply pressure, then engine output is improved, but device complexity and weight increase
Solution Approach 1:
The patent integrates the turbocharger directly with the engine by mounting it on the exhaust manifold, merging two previously separate components. This integration reduces the number of separate parts and connections while maintaining the pressure-increasing function to improve engine output.
Solution Approach 2:
The exhaust manifold serves dual functions: as an exhaust gas collection component and as a mounting base for the turbocharger. This multi-functionality reduces the need for separate mounting structures and simplifies the overall system architecture.
2Weight of stationary object
If components are integrated directly with the engine, then system weight is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The turbocharger is designed with pre-formed mounting structures that align with standardized locations on the exhaust manifold. This preliminary preparation of mounting interfaces simplifies the assembly process and reduces the precision requirements during final installation.
3Reliability
If the exhaust gas heat exchanger is inclined, then condensed water discharge is improved, but device complexity increases
Solution Approach 1:
The exhaust gas heat exchanger is designed with an inclined structure that uses gravity to naturally drain condensed water to the lowest point. This gravitational drainage creates an equipotential flow path for water removal, preventing accumulation and corrosion without requiring additional pumping or complex drainage systems.
4Ease of manufacture
If separate components are used, then ease of manufacture is improved, but vibration-induced damage increases
Solution Approach 1:
The turbocharger and exhaust gas heat exchanger are integrated as unified assemblies mounted directly on the engine's exhaust manifold. This merging eliminates separate mounting connections that would be susceptible to vibration-induced loosening and damage, while the modular design maintains ease of manufacture through standardized interfaces.
