Solution Overview

Problem

The existing methods for assembling heater assemblies for non-nicotine pod systems lack efficient mechanisms for aligning and securing wicks with heater elements, which can lead to inconsistent vapor production and assembly challenges.

Innovation Solution

An apparatus comprising a base, wick feed, slide, and holder is used to align and secure a wick within a heater assembly, utilizing a wick retainer, cutter, and rotatable components to guide and lock the wick in place, ensuring proper capillary action and vaporization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If existing assembly methods are used without specialized alignment mechanisms, then device complexity is reduced, but manufacturing precision of wick-heater alignment deteriorates

Engineering Contradiction:
Improvewick-heater alignment precisionVSAvoidassembly apparatus complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The wick feed acts as an intermediary component between the wick and heater assembly. It provides a structured pathway that guides the wick into precise alignment with the heater element, eliminating the need for complex external alignment mechanisms while ensuring consistent manufacturing precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The wick feed is pre-configured with channels and guides that establish the correct wick position before the wick contacts the heater. This preliminary alignment structure ensures that when assembly occurs, the wick is already positioned correctly, eliminating the need for complex real-time alignment mechanisms.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual wick positioning is used, then device complexity is minimized, but reliability of vapor production deteriorates due to inconsistent alignment

Engineering Contradiction:
Improvevapor production consistencyVSAvoidassembly mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The wick feed serves as a mediating structure that ensures consistent wick-heater alignment every time assembly occurs. Its fixed channels and guides provide repeatable positioning, guaranteeing reliable vapor production without requiring complex active control mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The alignment features are built into the wick feed structure in advance, creating a predetermined path for the wick. This preliminary configuration ensures that every assembly produces the same alignment quality, eliminating variability and ensuring consistent vapor production.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If complex alignment mechanisms are added to the assembly apparatus, then manufacturing precision of wick positioning is improved, but ease of manufacture deteriorates

Engineering Contradiction:
Improvewick positioning precisionVSAvoidassembly apparatus manufacturing ease
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

Instead of adding complex external alignment mechanisms, the solution incorporates alignment features directly into the wick feed itself. This intermediary component handles all positioning requirements through its internal structure, simplifying the overall apparatus while maintaining high manufacturing precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The alignment function is merged with the wick feed structure. The channels, guides, and positioning features are integrated into the single wick feed component rather than being separate mechanisms, reducing the number of parts and simplifying manufacturing.

Inventive Principle:
Principle #5Merging (Combining)
