Engineering Contradiction Analysis
1Reliability
If different battery packs are prepared for electric tools with different rated working voltages, then the electric tools can operate at their rated voltages, but the operation becomes complicated, the cost increases, and the resource is wasteful
Solution Approach 1:
The battery pack is designed with four energy units that can be connected in different configurations (series, parallel, or combinations) to provide multiple output voltages. This allows a single battery pack design to serve multiple electric tools with different voltage requirements, eliminating the need for separate battery packs for each voltage level and reducing operational complexity
Solution Approach 2:
The battery pack incorporates switching circuitry that can dynamically reconfigure the connection states of the four energy units based on the voltage requirements of the connected electric tool. The system can switch between series connections for higher voltages, parallel connections for lower voltages, or mixed configurations, providing adaptive voltage output without requiring multiple fixed battery packs
2Reliability
If different battery packs are prepared for electric tools with different rated working voltages, then the electric tools can operate at their rated voltages, but the cost increases
Solution Approach 1:
By designing a universal battery pack with four energy units that can output multiple voltages through different connection configurations, the invention eliminates the need to manufacture and inventory multiple types of battery packs for different voltage levels. This single-design approach reduces manufacturing complexity, material costs, and inventory management expenses while ensuring reliable voltage matching for various electric tools
3Reliability
If different battery packs are prepared for electric tools with different rated working voltages, then the electric tools can operate at their rated voltages, but the resource is wasteful
Solution Approach 1:
The battery pack design with four reconfigurable energy units allows a single battery pack to replace multiple dedicated battery packs, reducing resource waste by eliminating duplicate energy storage components. The same four energy units can be configured to serve different voltage requirements, maximizing resource utilization and reducing the total amount of materials needed across the product line
