Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a regulation circuit is used to manage voltage and current paths during different operational modes, then battery protection and safety are improved, but device complexity increases
Solution Approach 1:
The circuit is divided into two distinct operational modes (first mode and second mode) with separate transistor sets for each direction of current flow. This segmentation allows independent optimization of each mode's protection mechanism, improving battery protection while keeping each mode's circuit relatively simple
Solution Approach 2:
The circuit dynamically switches between different operational modes based on charging/discharging requirements. The regulation circuit and transistor sets are activated or deactivated depending on the operational mode, providing adaptive protection without requiring complex permanent circuitry for all scenarios
2Object-affected harmful factors
If distinct current paths are created for different operational modes, then battery safety during charging and discharging is improved, but device complexity increases
Solution Approach 1:
The regulation circuit acts as an intermediary between the power source and battery, controlling and managing current flow. It mediates the interaction between charging and discharging operations, ensuring safe current paths are established without requiring direct complex connections between all components
Solution Approach 2:
The transistor sets and regulation circuit serve multiple functions: they control current direction, regulate voltage levels, and provide protection during both charging and discharging modes. This multi-functionality reduces the need for separate dedicated circuits for each function

AI summary
The present disclosure provides a circuitry electrically connected to a battery, a regulation circuit and an operating method thereof. The circuitry includes a regulation circuit, a first transistor set and a second transistor set. The regulation circuit includes a first node, a second node and a third node. The first node electrically connects to a power source, and the second node electrically connects to a cathode of the battery. When the circuitry is operated in a first mode, the first node electrically connects to the third node through the first transistor set to create a first path from the first node to the second node. When the circuitry is operated in a second mode, the second node electrically connects to the third node through the second transistor set to create a second path from the second node to the first node.
