Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric devices struggle with wireless communication interlocking operations due to the need for proximity wireless communication devices on both devices, leading to ambiguity in connecting with multiple devices present in the vicinity, and lack of priority connection control.
Innovation Solution
A battery pack equipped with a wireless communication part that prioritizes connection with an electric device over an information terminal, establishes a wireless connection based on priority settings and elapsed time, and stores connection conditions to ensure reliable connection with a target device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If proximity wireless communication devices are mounted on both electric device bodies to enable interlocking operations, then wireless communication capability is improved, but device complexity increases and connection ambiguity occurs when multiple devices are present
Solution Approach 1:
The wireless communication function is extracted from the electric device body and relocated to the battery pack. The battery pack now contains the wireless communication device and serves as the communication interface for the entire electric tool system, allowing the electric device body to remain simple while still enabling wireless interlocking operations.
Solution Approach 2:
The battery pack acts as an intermediary between the electric device body and external devices. It contains the wireless communication device and handles all communication operations, mediating between the simple electric device body and the complex wireless communication requirements.
2Adaptability or versatility
If the battery pack equips with wireless communication means to enable interlocking operations, then wireless communication capability is improved, but connection ambiguity arises when multiple electric device bodies are present in the vicinity
Solution Approach 1:
The system performs preliminary pairing actions in advance. When multiple devices are present, the battery pack uses predetermined pairing information and priority rules to pre-determine which device to connect with, eliminating connection ambiguity before the actual communication operation begins.
Solution Approach 2:
The system implements feedback mechanisms through priority connection control. The battery pack receives signals from multiple devices, applies priority rules based on predetermined information, and provides feedback by establishing connections only with high-priority devices, ensuring reliable and unambiguous connections.
3Reliability
If priority connection control is implemented to resolve connection ambiguity, then connection reliability is improved, but control complexity increases
Solution Approach 1:
Priority connection control rules and device identification information are predetermined and stored in the battery pack before actual communication operations. This preliminary setup eliminates the need for complex real-time decision-making algorithms, reducing control complexity while maintaining high connection reliability.
