Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If additional electronic components and processors are added to increase computational capability, then the processing power and intelligence of the autonomous driving system is improved, but the heat generation increases and conventional cooling systems become inadequate
Solution Approach 1:
The patent merges the cooling functions for multiple electronic components into a single integrated cooling assembly. The first and second electronics radiators are positioned adjacent to each other and to the condenser, sharing a common cooling fluid circulation system. This consolidation provides enhanced cooling capacity for the high-heat-generating processors and electronic components without requiring separate cooling systems for each component, thereby resolving the heat management challenge associated with increased computational power.
2Temperature
If dedicated cooling systems and complex conduit networks are implemented to cool electronic components, then the cooling capability is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple cooling functions into a single integrated assembly where the first electronics radiator, second electronics radiator, and condenser share common cooling fluid pathways. The cooling fluid circulates through all components via a unified network, eliminating the need for separate dedicated cooling systems for each electronic component. This reduces overall system complexity while maintaining adequate cooling capability for all high-heat-generating components.
Solution Approach 2:
The cooling assembly serves multiple functions simultaneously: the condenser cools the cooling fluid, the first electronics radiator cools processors, and the second electronics radiator cools additional electronic components. All these functions are achieved through a single multi-functional cooling system that circulates cooling fluid through multiple components in series, providing universal cooling capability across different electronic subsystems without requiring separate dedicated systems.
3Temperature
If multiple radiators are positioned in front of the vehicle, then the cooling performance for electronic components is improved, but the device complexity and arrangement complexity increase
Solution Approach 1:
The patent positions the first electronics radiator and second electronics radiator adjacent to each other in front of the vehicle, creating a compact clustered arrangement. Both radiators are thermally coupled to the cooled electronics through cooling lines and share common cooling fluid pathways. This merged spatial arrangement provides enhanced cooling performance for multiple electronic components while maintaining a compact footprint that simplifies vehicle integration compared to dispersed radiator placements.
