Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an anti-reverse connection interface is provided on the battery rod to prevent reverse connection, then connection reliability is improved, but device complexity increases and user flexibility is reduced

Engineering Contradiction:

Improveconnection reliabilityVSAvoidinterface complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The battery rod interface is designed to accept both forward and reverse insertion of vaporizers. The driving identification circuit automatically detects the insertion direction and switches to the appropriate operating mode, making the interface universal and eliminating the need for complex anti-reverse connection structures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The driving chip changes its operating parameters based on the detected insertion direction. When reverse insertion is detected, the driving identification circuit switches to reverse insertion mode, adjusting electrical parameters to ensure proper operation regardless of insertion direction.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If an anti-reverse connection interface is provided to prevent reverse connection, then harmful factors are reduced, but ease of operation deteriorates

Engineering Contradiction:

Improvedamage from reverse connectionVSAvoiduser flexibility

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Instead of preventing reverse insertion mechanically, the patent converts the potentially harmful reverse connection into a beneficial feature by using the driving identification circuit to automatically detect and adapt to the insertion direction, allowing users to insert the vaporizer in any direction without risk of damage.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The driving identification circuit performs automatic direction detection and mode switching without requiring user intervention. The system self-adjusts to the correct operating mode based on the detected insertion direction, eliminating the need for users to worry about correct insertion orientation.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If a driving identification circuit is added to detect insertion direction, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveinsertion direction adaptabilityVSAvoidcircuit complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The driving identification circuit is integrated into the existing driving chip, merging the direction detection function with the power supply control function. This integration approach enables adaptability to different insertion directions while minimizing the increase in overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A battery rod for driving a vaporizer inserted therein includes: a driving chip; and a driving identification circuit connected to the driving chip. When the vaporizer is inserted in the battery rod, the driving chip determines that the vaporizer is forwardly inserted or reversely inserted through the driving identification circuit and controls the driving identification circuit to operate in a forward insertion mode or a reverse insertion mode.
