Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjustable cooling pump and/or adjustable cooling fan is provided to control cooling, then the cooling power can be adjusted, but the device complexity and energy consumption increase
Solution Approach 1:
The patent extracts the active adjustment mechanism (cooling pump and fan) and replaces it with a passive shutter arrangement that modulates air flow to the heat exchanger. This removes the complex adjustable components while preserving the ability to control cooling power through simple shutter positioning.
Solution Approach 2:
The shutter arrangement operates passively to regulate air flow and cooling power without requiring external energy input or complex control systems. The system uses the natural air flow and heat exchanger performance, modulated by shutter position, to achieve cooling adjustment autonomously.
2Adaptability or versatility
If an adjustable cooling pump and/or adjustable cooling fan is provided to control cooling, then the cooling power can be adjusted, but the energy consumption increases
Solution Approach 1:
The patent removes the energy-consuming adjustable cooling pump and fan from the system, replacing them with a passive shutter mechanism that achieves cooling power adjustment without active energy input, thereby eliminating the associated energy consumption.
Solution Approach 2:
The shutter arrangement provides self-service cooling power adjustment by passively modulating air flow to the heat exchanger based on environmental conditions and cooling requirements, without requiring external energy sources or active control systems.
3Device complexity
If a shutter arrangement is introduced to regulate air flow, then the device complexity is reduced and energy consumption decreases, but the manufacturing cost may increase
Solution Approach 1:
The shutter arrangement uses simple, inexpensive materials and construction methods to create an effective air flow regulation mechanism. The design prioritizes cost-effective implementation over complex engineered solutions, accepting that the shutter components may be simpler and potentially replaceable.
