Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a replaceable cartridge design is employed to increase battery component reuse cycles, then the number of cycles for battery component reuse is increased, but the reliability of proper atomizer connection is reduced due to installation errors or defects
Solution Approach 1:
The detection circuit performs preliminary detection of the atomizer connection status before the user activates the device. The control circuit receives detection signals and determines whether the atomizer is properly connected before allowing operation, preventing malfunction due to improper installation while maintaining the replaceable cartridge design for extended reuse cycles
Solution Approach 2:
The detection circuit continuously monitors the atomizer connection status and provides feedback signals to the control circuit. The control circuit adjusts the working status of the atomizer based on this feedback, ensuring reliable operation while maintaining the replaceable cartridge design that extends battery component reuse cycles
2Device complexity
If no detection circuit is implemented, then the device complexity is reduced, but the user experience deteriorates due to inability to determine device status
Solution Approach 1:
The detection circuit automatically detects and reports the atomizer connection status without requiring user intervention or complex interfaces. The control circuit autonomously determines the device status based on detection signals and controls the atomizer working status accordingly, enhancing user experience while maintaining relatively simple circuit structure
Solution Approach 2:
The detection circuit acts as an intermediary between the atomizer and the control circuit, providing status information without requiring direct user interaction with complex circuitry. This intermediary function enhances user experience by automatically determining device status while keeping the overall circuit structure relatively simple
