Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If natural heat dissipation is used, then the wireless charging system is simple in structure, but the charging speed is limited and heat dissipation efficiency is low
Solution Approach 1:
The heat dissipation system is segmented into multiple independent air ducts: a first air duct for dissipating heat from the charging panel and a second air duct for dissipating heat from the electronic device. Each air duct has its own air vents and airflow path, allowing independent heat dissipation optimization for different components without increasing overall system complexity
Solution Approach 2:
Air is introduced as an intermediary cooling medium that flows through the air ducts to carry heat away from both the charging panel and the electronic device. The air acts as a heat transfer medium, enabling efficient heat dissipation without direct thermal contact between components
2Productivity
If one fan is used for heat dissipation, then the structure is relatively simple, but the heat dissipation capability is insufficient to improve charging performance
Solution Approach 1:
The single fan is replaced with multiple fans, each dedicated to a specific air duct. The first fan drives airflow through the first air duct to cool the charging panel, while the second fan drives airflow through the second air duct to cool the electronic device. This segmentation of cooling functions enhances overall heat dissipation capability and prevents heat accumulation that would limit charging speed
Solution Approach 2:
The system changes the parameter of fan quantity from one to multiple, and adjusts airflow parameters (flow rate, direction, temperature) for each air duct independently. This allows optimization of heat dissipation parameters to match the specific thermal requirements of different components, thereby improving charging speed without excessive energy loss
3Reliability
If air vents are added to create air ducts, then heat dissipation efficiency is improved, but the device structure becomes more complex
Solution Approach 1:
The base plate serves multiple functions: it provides structural support for the electronic device and simultaneously houses the air duct system for heat dissipation. The air vents are integrated into the base plate structure, allowing the same component to fulfill both mechanical and thermal management functions, thereby improving heat dissipation efficiency without proportionally increasing structural complexity
Solution Approach 2:
The air ducts are nested within the base plate structure. The first air duct is formed within the base plate to cool the charging panel, while the second air duct is also integrated into the base plate to cool the electronic device. This nesting approach allows the heat dissipation system to be embedded within existing structural components, improving thermal management without significantly increasing overall device complexity
