Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate communication systems are developed for each power tool type, then communication compatibility for each specific tool is ensured, but development cost and system complexity increase significantly
Solution Approach 1:
The patent implements a universal communication protocol that enables a single communication system to work across multiple power tool types and platforms. The protocol defines standardized message formats, data structures, and communication rules that can be applied universally, eliminating the need for separate communication systems for each tool type while maintaining reliability through standardized interfaces.
Solution Approach 2:
The communication system is segmented into distinct layers including a universal protocol layer and implementation-specific adaptation layers. This segmentation allows the core communication framework to remain simple and universal while handling tool-specific variations through modular adaptation modules, thereby reducing overall system complexity.
2Adaptability or versatility
If separate communication systems are developed for each power tool type, then specific tool communication requirements are met, but development time and maintenance cost increase
Solution Approach 1:
The patent establishes a preliminary universal communication framework that defines core protocols, message formats, and data structures in advance. This preliminary action creates a reusable foundation that can be rapidly adapted to specific tool types without requiring complete system redesign, significantly reducing development time for new tool implementations.
Solution Approach 2:
The universal protocol acts as an intermediary layer between the communication infrastructure and tool-specific implementations. This mediator enables standardized communication patterns to be applied across different tool types while allowing tool-specific requirements to be handled through adaptation modules, reducing both development time and maintenance complexity.
3Device complexity
If a universal protocol is implemented across diverse power tools, then development cost and system complexity are reduced, but communication compatibility across different tool types must be ensured
Solution Approach 1:
The patent applies local quality by allowing tool-specific adaptation modules to handle platform-specific variations while the universal protocol handles common communication requirements. This enables the system to maintain simplicity through standardization while ensuring compatibility through localized adaptation where needed, balancing reduced complexity with maintained reliability.
4Ease of operation
If tool-specific communication protocols are used, then precise control for each tool type is achieved, but interoperability and data exchange between different tool types become difficult
Solution Approach 1:
The universal protocol serves as an intermediary that enables interoperability between different tool types while preserving tool-specific control capabilities. Standardized message formats and data structures allow different tools to communicate effectively, while adaptation modules ensure that tool-specific control requirements are met through protocol-compliant implementations.
Data Source
AI summary
A method for communicating between motorized power tools includes establishing, using a physical interface of a first power tool, a wireless radio link between the first power tool and a second power tool. The first power tool has a first motor and the second power tool has a second motor. A signal is received over the wireless radio link, via the physical interface, at the first power tool from the second power tool using a first wireless communication protocol. The signal includes an identifier. The second power tool is verified as authorized to send the signal to the first power tool based on the identifier. A tool component of the first power tool is controlled responsive to the signal.
