Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cooling technologies are used, then cooling function is provided, but cooling efficiency is insufficient and devices cannot be made more compact
Solution Approach 1:
The patent applies ultrasonic vibration to the working fluid in the cooling system. A piezoelectric element or magnetostrictive material is used to generate ultrasonic vibrations that enhance fluid circulation and heat transfer efficiency, allowing for more effective cooling in a compact configuration
Solution Approach 2:
The patent changes the physical state and motion parameters of the working fluid by introducing ultrasonic vibration. This increases the fluid's kinetic energy and improves convective heat transfer, enabling higher cooling efficiency without increasing system volume
2Volume of stationary object
If cooling system size is reduced for compact devices, then device compactness is improved, but heat dissipation capability deteriorates
Solution Approach 1:
Ultrasonic vibration is introduced to the working fluid to enhance heat transfer coefficients and improve convective cooling performance in the compact heat exchanger, compensating for the reduced surface area available for heat dissipation
Solution Approach 2:
The patent optimizes the hydraulic flow characteristics of the working fluid through ultrasonic agitation, creating micro-turbulence and enhanced mixing that improves heat transfer efficiency despite the compact heat exchanger geometry
