Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a refillable reservoir is provided with a simple filling mechanism, then ease of operation is improved, but manufacturing precision and control over the amount of aerosol-generating material transferred deteriorates

Engineering Contradiction:
Improveease of refillingVSAvoidprecision of material transfer amount
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system incorporates sensors to detect the amount of aerosol-generating material in the reservoir and provides feedback to the control circuit. The control circuit adjusts the transfer mechanism operation based on this feedback to achieve the desired material amount, resolving the contradiction between simple operation and precise control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces purely mechanical filling mechanisms with an electronically controlled transfer mechanism that uses a motor-driven pump or valve system. This allows precise control over the amount of material transferred while maintaining ease of operation through automated control based on sensor feedback.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If the transfer mechanism operates in a single direction only, then device complexity is reduced, but reliability of refilling process deteriorates due to inability to correct overfilling or underfilling

Engineering Contradiction:
Improvecomplexity of transfer mechanismVSAvoidreliability of refilling process
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The transfer mechanism is designed to be dynamically controllable, able to operate in both forward and reverse directions based on real-time conditions. The control circuit adjusts the direction and duration of transfer operations to correct deviations from the target material amount, improving reliability without requiring a fundamentally complex mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters (direction, duration, intensity of transfer) based on feedback from sensors. By adjusting these parameters dynamically, the same transfer mechanism can achieve reliable refilling across different conditions without requiring multiple specialized mechanisms.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If the reservoir is designed with a fixed capacity, then manufacturing precision is improved, but adaptability to different refill scenarios deteriorates

Engineering Contradiction:
Improveprecision of reservoir capacityVSAvoidadaptability to different refill amounts
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The transfer mechanism is designed with variable control capabilities, allowing it to transfer different amounts of aerosol-generating material based on the current reservoir level and desired target level. This dynamic adjustment capability provides adaptability while the reservoir itself maintains a fixed, precisely-manufactured capacity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The refilling process is segmented into multiple controlled transfer steps rather than a single fixed operation. The control circuit divides the total required transfer into smaller increments, adjusting each step based on real-time measurements, which allows the fixed-capacity reservoir to be filled to various target levels adaptably.

Inventive Principle:
Principle #1Segmentation
