Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the size and power of the ventilation device are increased to ensure adequate airflow for heat exchange, then the thermal performance is improved, but the energy consumption increases and the autonomy of the vehicle is reduced
Solution Approach 1:
The patent applies the dynamics principle by implementing adjustable guide walls and deflectors that can change their position according to operating conditions. The guide walls can be adjusted to optimize airflow patterns through the heat exchanger, allowing the system to maintain effective thermal performance while consuming less energy by adapting to different operational requirements rather than relying on a fixed high-power ventilation device
Solution Approach 2:
The patent employs parameter changes by modifying airflow characteristics through adjustable guide walls and deflectors. By changing the orientation and position of these components, the system can optimize air flow distribution across the heat exchanger surfaces, improving thermal exchange efficiency without requiring increased ventilation device power, thus reducing energy consumption
2Reliability
If the size and power of the ventilation device are increased to ensure adequate airflow for heat exchange, then the thermal performance is improved, but the weight of the cooling module increases
Solution Approach 1:
The adjustable guide walls and deflectors allow the system to optimize airflow dynamically, eliminating the need for an oversized ventilation device. This dynamic adjustment capability enables the use of a more compact, lighter cooling module that can adapt to different thermal requirements rather than being designed for maximum capacity at all times
Solution Approach 2:
By changing the parameters of airflow distribution through adjustable components, the system achieves effective heat exchange with a smaller, lighter ventilation device. The ability to modify flow patterns allows a reduced-weight cooling module to maintain thermal performance that would otherwise require a heavier, more powerful system
3Volume of moving object
If the compartment size is reduced and cluttered with obstacles to accommodate vehicle design constraints, then the vehicle integration is improved, but the airflow evacuation is hindered
Solution Approach 1:
The patent uses adjustable guide walls and deflectors to dynamically optimize airflow paths through the compact compartment. These movable components can be positioned to navigate around obstacles and direct airflow efficiently through the heat exchanger, maintaining effective heat exchange in a reduced-size compartment that would otherwise be too cluttered for adequate airflow
Solution Approach 2:
The guide walls and deflectors create three-dimensional airflow management within the compact compartment. By utilizing vertical and lateral flow directions in addition to horizontal flow, the system achieves effective airflow evacuation through the heat exchanger despite the constrained compartment dimensions and presence of obstacles
