Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication protocols are used for data transmission, then the reliability of communication is improved, but the energy consumption increases
Solution Approach 1:
The system performs preliminary actions by determining the power tool location and identifying a prioritized set of communication protocols before actual data transmission occurs. This pre-planning allows the system to select the most energy-efficient protocol in advance, avoiding the need to attempt multiple protocols during transmission, thus resolving the contradiction between reliability and energy consumption.
Solution Approach 2:
The system changes the parameter of protocol selection based on the power tool location. By adapting the communication protocol choice to the specific location and context, the system optimizes energy consumption while maintaining reliable communication. The prioritized sequence of protocols is dynamically selected based on location-dependent factors.
2Reliability
If multiple communication protocols are attempted in sequence, then the reliability of data transmission is improved, but the time consumption increases
Solution Approach 1:
The system performs preliminary identification of the prioritized communication protocol sequence based on location before transmission. This pre-selection process eliminates the need for trial-and-error protocol attempts during actual data transmission, significantly reducing time consumption while maintaining high reliability through informed protocol selection.
Solution Approach 2:
The system changes the communication protocol parameter based on location context, selecting the most appropriate protocol from the prioritized set for each transmission scenario. This adaptive approach avoids unnecessary protocol switching during transmission, reducing time loss while ensuring reliable communication through context-appropriate protocol selection.
3Use of energy by moving object
If location-dependent protocol selection is implemented, then the energy efficiency is improved, but the device complexity increases
Solution Approach 1:
The electronic controller is designed with multi-functionality, serving both as the power tool's control unit and as the location determination and protocol selection system. By integrating these functions into a single component, the system improves energy efficiency through location-dependent protocol selection without proportionally increasing device complexity, as the same hardware performs multiple roles.

AI summary
A power tool and method for prioritized communication is disclosed. A power tool may include an electronic controller including a process and a memory, and a transceiver communicatively coupled to the electronic controller. The electronic controller assigns a first geographic area to a first prioritized set of communication protocols based on a prior successful transmission in the first geographic area using a first communication protocol, determines a power tool location of the power tool within the first geographic area, and identifies a first prioritized set of communication protocols corresponding to the power tool location. The first prioritized set of communication protocols may include two or more communication protocols in a prioritized sequence. Then, the electronic controller transmits, via the transceiver, a communication according to a first communication protocol of the first prioritized set of communication protocols. The first communication protocol may be first in the prioritized sequence.
