Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high current is supplied to the battery for fast charging, then charging speed is improved, but heat generation increases and charging efficiency decreases
Solution Approach 1:
The charging circuit is divided into multiple sub-circuits (first charging circuit, second charging circuit, third charging circuit) that can operate independently or in combination. This segmentation allows the total charging current to be distributed across multiple paths, reducing the current burden on any single circuit and thereby reducing heat generation and power loss while maintaining fast charging capability.
2Productivity
If high input power is supplied to the charging circuit, then charging speed is improved, but heat generation increases and affects surrounding components
Solution Approach 1:
The charging circuit is divided into multiple sub-circuits (first charging circuit, second charging circuit, third charging circuit) that can operate independently or in combination. This segmentation allows the total charging current to be distributed across multiple paths, reducing the current burden on any single circuit and thereby reducing heat generation and power loss while maintaining fast charging capability.
Solution Approach 2:
The system dynamically selects and switches between different charging circuits based on real-time conditions such as battery charge level, temperature, and charging speed requirements. This dynamic adaptation allows the system to optimize the balance between charging speed and heat generation, using multiple circuits when high speed is needed and switching to fewer circuits when heat management is prioritized.
3Productivity
If multiple charging circuits are used simultaneously, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
The charging circuit is divided into multiple sub-circuits (first charging circuit, second charging circuit, third charging circuit) that can operate independently or in combination. This segmentation allows the total charging current to be distributed across multiple paths, reducing the current burden on any single circuit and thereby reducing heat generation and power loss while maintaining fast charging capability.
Solution Approach 2:
The multiple charging circuits are designed with overlapping functionality, where each circuit can operate independently or in combination with others. This multi-functionality allows the system to achieve high charging efficiency when needed while also being able to operate with reduced complexity by using fewer circuits, thus adapting to different operational requirements.
