Innovation Solution
An electric tool power supply with a vehicle starting function, equipped with a power supply component, first and second output interfaces, allowing it to provide operating voltage to tools and output high current to vehicle starters for ignition, enhancing the battery's multi-purpose use and extending its lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the battery is designed for single-purpose use in electric tools, then the battery structure can be simple and focused, but the utilization rate decreases and capacity/service life reduce due to idle time
Solution Approach 1:
The battery is designed with dual functionality: it can power electric tools through the first output interface and simultaneously serve as a vehicle starting power source through the second output interface. This multi-functional design allows the battery to be used in multiple scenarios, significantly improving its utilization rate and extending its effective service life by reducing idle time between uses
2Power
If the battery outputs instantaneous large current to vehicle starter, then the vehicle starting function is achieved, but the battery structure and protection mechanisms become more complex
Solution Approach 1:
The power supply component is divided into multiple battery modules that can be independently managed. Each module contributes to the overall power output, and the segmented structure allows for better current distribution and thermal management during high-current discharge to the vehicle starter, reducing the complexity burden on any single component
Solution Approach 2:
A control circuit acts as an intermediary between the power supply component and the second output interface. This control circuit manages the instantaneous large current output to the vehicle starter, providing protection mechanisms and current regulation without requiring the battery structure itself to be overly complex
