Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery pack designs and data transmission methods fail to efficiently collect and analyze data for both normal operation and maintenance purposes, leading to inefficiencies in product development and maintenance, particularly in outdoor power tools and portable power supply devices, resulting in high manpower and material resource costs.
Innovation Solution
A battery pack with dual data transmission terminals and a controller that switches between normal operation and data transmission modes, allowing for the collection and analysis of operational and historical data, including temperature and usage information, via wireless communication, facilitating remote data processing and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single data transmission terminal is used in battery pack, then device complexity is reduced, but data collection efficiency and functionality are insufficient
Solution Approach 1:
The patent divides the data transmission function into two separate terminals: a first terminal for normal operational data and a second terminal for diagnostic and historical data. This segmentation allows each terminal to be optimized for its specific purpose, improving overall data collection efficiency without requiring a completely complex multi-terminal system.
Solution Approach 2:
The controller is designed to manage multiple functions including switching between different data transmission modes, processing both operational and diagnostic data, and coordinating communication through different terminals. This multi-functionality reduces the need for separate dedicated components for each function.
2Loss of information
If on-site data collection is performed for product development and maintenance, then data accuracy is improved, but manpower and time resources are consumed
Solution Approach 1:
The battery pack continuously collects and stores operational data, temperature information, and usage history in its memory during normal operation. This preliminary data collection means that when maintenance is needed, all necessary data is already available immediately, eliminating the need for time-consuming on-site data gathering.
Solution Approach 2:
The controller acts as an intermediary that automatically manages data collection, processing, and transmission. It continuously monitors battery parameters, stores data in memory, and can transmit it either through the first terminal during operation or the second terminal during maintenance, reducing the need for human intervention in data collection.
3Ease of repair
If traditional single-mode data transmission is used, then device simplicity is maintained, but diagnostic capability and maintenance efficiency are insufficient
Solution Approach 1:
The system dynamically switches between two operational modes: normal operation mode using the first terminal, and data transmission/diagnostic mode using the second terminal. The controller automatically transitions between modes based on operational requirements, providing enhanced diagnostic capability without requiring a permanently complex active configuration.
