Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a charger is designed to charge multiple types of devices simultaneously, then the versatility and functionality of the charger is improved, but the device complexity and structural design become more difficult
Solution Approach 1:
The patent implements a universal charger design with multiple output ports (USB Type-C, USB Type-A, DC ports) that can simultaneously charge different types of devices including smartphones, tablets, laptops, and automobiles. The charger uses a single integrated circuit board with multiple charging circuits that can operate independently or concurrently, allowing one charger to replace multiple dedicated chargers while maintaining simple user operation.
Solution Approach 2:
The charger divides its charging functionality into separate independent circuits for different device types. Each output port has its own charging circuit that can be independently controlled and managed by the microprocessor. This segmentation allows the charger to handle multiple device types simultaneously without requiring a single complex circuit, simplifying the overall design while achieving multi-functionality.
2Ease of operation
If a charger is designed to charge devices while being connected to AC power supply, then the convenience of use is improved, but the safety and reliability of charging becomes problematic
Solution Approach 1:
The patent incorporates a microprocessor that continuously monitors the charging state of both the internal battery and connected devices. The system detects whether the internal battery is charged and whether devices are connected to output ports, then automatically controls the charging circuits to prevent unsafe charging conditions. This feedback mechanism ensures that devices are only charged when safe to do so, maintaining reliability while enabling convenient simultaneous charging and power supply connection.
3Weight of moving object
If a portable charger has limited battery capacity, then the portability and compactness is improved, but the ability to charge large devices like notebooks and automobiles is insufficient
Solution Approach 1:
The patent designs a portable charger with a dynamically adaptable charging system. The microprocessor monitors the power requirements of connected devices and automatically adjusts the charging current and voltage output. When a high-power device like a notebook or automobile is detected, the system dynamically increases power delivery within the limits of the internal battery capacity, maximizing the available power while maintaining portability. The charger can also charge multiple low-power devices simultaneously, effectively utilizing the limited battery capacity across multiple devices.
