Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different manufacturers use different charging and discharging protection standards and structures, then each manufacturer can optimize their products according to their own requirements, but battery packs become incompatible across brands, leading to increased costs and management difficulties for users
Solution Approach 1:
The patent implements a universal charging and discharging protection system where the battery pack includes a standardized protection circuit board with uniform charging and discharging protection standards. This standardized design enables compatibility across different battery packs and electric tools from the same brand, allowing users to interchangeably use battery packs without compatibility issues, thereby achieving multi-functionality and universality in the battery ecosystem.
Solution Approach 2:
The patent standardizes key parameters such as charging voltage thresholds, discharging voltage thresholds, and protection circuit board specifications across all battery packs of a brand. By fixing these parameters to uniform values, the system ensures consistent charging and discharging protection behaviors, enabling interoperability while maintaining brand-specific optimization within the standardized framework.
2Adaptability or versatility
If users purchase multiple battery packs and chargers for different brands of electric tools, then they can use tools from different brands, but they face increased costs, space consumption, and management difficulties
Solution Approach 1:
The patent creates a universal battery pack design within a brand ecosystem, where a single battery pack model can be used across multiple electric tool models. The standardized protection circuit board and uniform charging/discharging standards allow users to purchase one battery pack and use it with various electric tools, eliminating the need to buy separate battery packs for each tool model or brand, thereby reducing the quantity of battery packs and chargers needed.
3Reliability
If battery packs lack anti-counterfeiting functions, then the system is simpler and cheaper to manufacture, but counterfeit battery packs can compromise safety and performance
Solution Approach 1:
The patent incorporates anti-counterfeiting verification modules and authentication mechanisms into the battery pack and protection circuit board during manufacturing. These verification features are built in advance before the battery pack reaches the user, enabling automatic authentication when the battery pack is connected to electric tools or chargers. This preliminary action ensures that only genuine battery packs can be used, preventing counterfeit products from compromising safety while maintaining streamlined operation for authorized users.

AI summary
A charging and discharging system with anti-counterfeiting function of a battery pack for an electric tool includes: a battery pack which includes a data acquisition module and a battery pack verification module; and at least one charge-discharge adapter which includes an adapter verification module, an adapter controller, and a discharging communication verification module. The adapter verification module communicates with the battery pack verification module for performing anti-counterfeiting verification, if the anti-counterfeiting verification is passed, the at least one charge-discharge adapter controls the battery pack to charge or discharge; the adapter controller receives data information from the data acquisition module and controls the discharging communication verification module to work, the discharging communication verification module selects a corresponding communication protocol according to a type of the discharge interface of the at least one charge-discharge adapter for communicating with the electric tool and controls the battery pack to charge the electric tool.
