Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional rechargeable battery devices use traditional connection ports, then they can maintain simple structure, but they cannot meet the increasing power transmission demands of modern electronic devices
Solution Approach 1:
The patent applies universality by integrating multiple connector types (USB Type-C and USB Type-A) into a single battery device, enabling it to serve multiple functions: charging power tools, charging smartphones, tablets, and laptops, and acting as a portable power bank. This multi-functional approach resolves the contradiction by providing high power transmission capability through USB Type-C for modern devices while maintaining compatibility with older devices through USB Type-A, thus meeting increasing power demands without requiring multiple separate battery devices
2Adaptability or versatility
If the battery device supports multiple connector types and Power Delivery protocol, then it can adapt to various electronic devices, but it increases the device complexity
Solution Approach 1:
The patent applies segmentation by providing separate USB Type-C and USB Type-A connectors as distinct interface options on the battery device. Each connector type is optimized for specific device categories: USB Type-C for high-power devices like laptops and tablets requiring Power Delivery protocol, and USB Type-A for older smartphones and devices. This segmented approach enhances adaptability to different devices while keeping the control logic relatively simple, as each connector operates independently with its own control circuit
3Power
If the battery device is designed for high-power transmission to meet future device requirements, then it can charge laptops and tablets, but it may be over-engineered for current power tool applications
Solution Approach 1:
The patent applies dynamics by implementing a controllable power transmission system that can dynamically adjust its output based on the connected device's requirements. The control circuit detects the device type and automatically adjusts the power transmission parameters: providing high power (up to 100W) for laptops and tablets through USB Type-C with Power Delivery, while delivering appropriate lower power levels for power tools and smartphones. This dynamic adaptation allows the battery device to be future-proof for high-power applications without being permanently over-engineered, as the high-power capability is activated only when needed
