Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an information obtaining component is disposed outside the battery to obtain internal information, then information can be obtained, but the component consumes battery current and increases power consumption
Solution Approach 1:
The patent extracts the power consumption function from the information obtaining component by providing a dedicated power supply module that supplies power independently. This separates the information obtaining function from the battery's power system, allowing information to be obtained without consuming battery current.
Solution Approach 2:
The patent introduces a power supply module as an intermediary between the information obtaining component and the battery. This intermediary provides dedicated power to the information obtaining component, preventing direct power consumption from the battery while still enabling information acquisition.
2Loss of information
If an information obtaining component is disposed outside the battery, then information can be obtained, but the battery cover structure becomes complex and costly
Solution Approach 1:
The patent merges the information obtaining component and power supply module into the battery's internal structure. The component is received in a receiving cavity within the battery housing, eliminating the need for external disposition through the battery cover and simplifying the overall structure.
Solution Approach 2:
The patent implements a nested structure where the information obtaining component and power supply module are housed within a receiving cavity of the battery. This nesting approach integrates multiple functions into a compact internal arrangement, avoiding external modifications to the battery cover.
3Loss of information
If an information obtaining component is disposed outside the battery, then information can be obtained, but the assembly process becomes complex and difficult to implement
Solution Approach 1:
The patent incorporates the power supply module and information obtaining component into the battery structure during the manufacturing process. The receiving cavity is pre-designed in the battery housing, allowing these components to be integrated in one assembly step rather than requiring post-manufacturing modifications or complex multi-step assembly procedures.
4Loss of information
If an information obtaining component is disposed outside the battery, then information can be obtained, but reliability of the overall system is reduced
Solution Approach 1:
The patent extracts the power supply function from the information obtaining component and provides it through a dedicated power supply module. This separation ensures that the information obtaining component has reliable dedicated power without being affected by battery power fluctuations or failures, improving overall system reliability.
Solution Approach 2:
The power supply module acts as an intermediary that isolates the information obtaining component from direct battery power dependency. This intermediary structure enhances reliability by providing stable, dedicated power to the information obtaining component while preventing potential power-related failures from affecting the battery's main function.
