Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvebattery component reuse cyclesVSAvoidatomizer connection status
Core Design Contradiction:
Duration of action of stationary objectVSReliability

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

Inventive Principle:
Principle #10Preliminary action

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

Inventive Principle:
Principle #23Feedback

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

Engineering Contradiction:
Improvecircuit structureVSAvoiduser experience
Core Design Contradiction:
Device complexityVSEase of operation

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

Inventive Principle:
Principle #25Self-service

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

Inventive Principle:
Principle #24Intermediary (Mediator)
