Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the liquid absorbing element keeps constant contact with the liquid storage space, then the liquid absorbing element can continuously absorb liquid, but the liquid absorbing element absorbs excessive liquid and causes liquid leakage

Engineering Contradiction:
Improveliquid absorption quantityVSAvoidliquid leakage
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The blocking element is made rotatable to dynamically control the communication between liquid inlet and outlet. By rotating the blocking element, the liquid absorbing element can be periodically connected or disconnected from the liquid storage space, preventing excessive liquid absorption while ensuring continuous operation capability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements periodic connection and disconnection of the liquid absorbing element with the liquid storage space through rotational movement of the blocking element. This periodic action allows the liquid absorbing element to absorb liquid in controlled intervals, preventing overflow and leakage while maintaining continuous vaping functionality

Inventive Principle:
Principle #19Periodic action

2Object-generated harmful factors

If the blocking element rotates to control liquid flow, then liquid leakage is prevented, but the device structure becomes more complex

Engineering Contradiction:
Improveliquid leakage preventionVSAvoidatomizer structure complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The blocking element serves multiple functions: it blocks liquid flow when needed, provides a rotational mechanism for control, and can be integrated with the atomization assembly structure. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The blocking element is integrated with the atomization assembly, merging the liquid control function with the existing atomizer structure. This integration avoids adding separate complex control mechanisms, keeping the overall device structure relatively simple while achieving leak prevention

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An exemplary atomizer (100) includes a housing (110), a liquid storage chamber (130), and an atomization assembly (140). The atomization assembly includes a main body (141) defining a liquid inlet (1411), a liquid absorbing element (143) arranged in the main body. The liquid storage chamber defines a liquid outlet (1311) fitting the liquid inlet in an inner sidewall (131) thereof, and a heating element (142). A blocking element (150) defining a through hole (151) is provided between an inner sidewall of the liquid storage chamber and the main body. One end of the housing is provided with a movable element (120). The movable element is capable of rotating relative to the housing to cause rotation of the blocking element, thus allowing the liquid inlet and the liquid outlet to be in communication through the through hole or allowing a sidewall of the blocking element to cut off the communication between the liquid inlet and the liquid outlet.
