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
The system 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 vibrates in sync with the engine to minimize damage and enhance heat collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air is supplied to the gas engine in a natural intake manner, then the structure is simple, but the air supply pressure is low (1 kPa to 2.5 kPa) resulting in reduced engine output
Solution Approach 1:
The patent integrates the turbocharger directly with the engine by mounting it on the exhaust manifold, merging two previously separate components into a unified assembly. This integration maintains structural simplicity while enabling pressurized air supply to improve engine output, resolving the contradiction between simplicity and performance.
Solution Approach 2:
The patent employs a turbocharger to pressurize the air supply to the engine, utilizing pneumatic principles to increase air pressure from natural intake levels (1-2.5 kPa) to pressurized levels (30+ kPa). This pneumatic enhancement directly addresses the low output issue while maintaining a relatively simple overall structure through integration.
2Adaptability or versatility
If components such as mixer, turbocharging device, intercooler, and regulator are fixed to a separate structure, then each component can be independently designed, but the overall length of tubes is longer and the structure is more complicated
Solution Approach 1:
The patent merges the turbocharger with the engine structure by mounting it directly on the exhaust manifold, eliminating the need for separate support structures and reducing tube lengths. This integration reduces overall system complexity while maintaining the functional independence of each component through standardized mounting interfaces.
3Ease of manufacture
If components are fixed to a separate structure, then assembly is flexible, but vibration causes damage to connection tubes and connected portions
Solution Approach 1:
By integrating the turbocharger directly with the engine's exhaust manifold, the patent eliminates relative vibration between separate components. The unified structure ensures that both the engine and turbocharger vibrate together as a single unit, preventing vibration-induced damage to connection tubes and improving reliability while maintaining assembly flexibility through standardized mounting.
4Ease of operation
If the exhaust gas heat exchanger is positioned separately from the engine, then heat collection path is clear, but heat collection efficiency is reduced due to exhaust pressure difference
Solution Approach 1:
The patent integrates the exhaust gas heat exchanger with the engine system, positioning it to directly utilize exhaust gases without creating additional pressure differences. This integration maintains clear heat collection paths while improving heat collection efficiency by eliminating the energy loss associated with exhaust pressure differences that occur in separate configurations.
