Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a charging station system is established to charge multiple power tools, then charging capability is improved, but data interaction and management between different tools are insufficient
Solution Approach 1:
The patent introduces a gateway device as an intermediary component that bridges the charging station and power tools. The gateway device includes communication modules that establish wireless connections with both the charging station and power tools, enabling data transmission between them. This mediator resolves the information loss problem by providing a dedicated data communication pathway separate from the power transmission pathway.
Solution Approach 2:
The gateway device is designed with multi-functionality, serving as both a communication bridge and a data processing unit. It can simultaneously handle multiple communication protocols (Wi-Fi, Bluetooth, cellular) and interact with multiple power tools and cloud servers, making the charging station system universally compatible with various power tool types while maintaining robust data interaction capabilities.
2Extent of automation
If power tools are connected to cloud servers for data management, then system management capability is improved, but connection reliability and data security are insufficient
Solution Approach 1:
The gateway device serves as a reliable intermediary between power tools and cloud servers. It maintains local buffering capabilities to store data temporarily, ensuring that cloud connectivity interruptions do not result in data loss. The gateway also implements security protocols for data encryption and authentication, enhancing connection reliability and data security while maintaining automated cloud management capabilities.
3Adaptability or versatility
If multiple communication protocols are supported for data interaction, then interoperability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple communication protocol modules into a single integrated gateway device. Rather than requiring separate devices for Wi-Fi, Bluetooth, and cellular communications, all protocol handlers are merged into one unit that manages multiple connection types simultaneously. This consolidation maintains high interoperability while reducing overall system complexity compared to using multiple separate devices.
