Solution Overview

Problem

Existing electronic smoking devices and capsules often have a bulky or complicated design that obstructs the aerosol flow and lacks a user-friendly, smooth shape, leading to issues with capsule mounting and stability.

Innovation Solution

The system features an electronic smoking device with a rechargeable battery and an atomizer, paired with a capsule having a triangular-like cross-sectional shape that allows for a snug fit with a circular interface, ensuring unobstructed aerosol flow and preventing unintentional rolling, while maintaining a smooth appearance and cost-effective manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the capsule has a circular cross-sectional shape, then it provides a smooth appearance and pleasant shape, but it cannot be tightly mounted in a circular interface leaving sufficient free space for aerosol flow

Engineering Contradiction:
Improvecapsule appearance smoothnessVSAvoidfree space for aerosol flow
Core Design Contradiction:
ShapeVSArea of stationary object

Solution Approach 1:

The capsule shell is given a triangular-like cross-sectional shape instead of a circular shape. This asymmetric polygonal shape allows the capsule to be tightly mounted in a circular interface while leaving maximum free space between the capsule and the interface, enabling unobstructed aerosol flow from the atomizer to the mouth end.

Inventive Principle:
Principle #4Asymmetry

2Area of stationary object

If the capsule has a triangular-like cross-sectional shape, then it allows tight mounting with maximum free space for aerosol flow, but it may complicate the manufacturing process

Engineering Contradiction:
Improvefree space for aerosol flowVSAvoidcapsule manufacturing complexity
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The cross-sectional shape of the capsule shell is changed from circular to triangular-like (polygonal). This parameter change in geometry allows the capsule to be tightly mounted in a circular interface while leaving sufficient free space for aerosol flow, and can be manufactured cost-effectively using appropriate molding techniques.

3Ease of manufacture

If the capsule has a circular cross-sectional shape, then it is easy to manufacture, but it may roll away unintentionally when placed on a surface

Engineering Contradiction:
Improvecapsule manufacturing simplicityVSAvoidcapsule stability against rolling
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The capsule shell is given a triangular-like cross-sectional shape instead of a circular shape. This asymmetric polygonal shape prevents the capsule from rolling away unintentionally when placed on a surface, while still allowing cost-effective manufacturing using appropriate molding techniques.

Inventive Principle:
Principle #4Asymmetry

4Reliability

If the capsule design includes ribs and ducts on the exterior surface to allow aerosol flow, then it enables aerosol passage, but it creates a bulky and complicated appearance

Engineering Contradiction:
Improveaerosol flow capabilityVSAvoidcapsule appearance simplicity
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The triangular-like cross-sectional shape of the capsule shell inherently creates channels and pathways for aerosol flow between the capsule surface and the circular interface, eliminating the need for additional ribs and ducts on the exterior surface. This maintains a smooth, simple appearance while ensuring reliable aerosol passage.

Inventive Principle:
Principle #4Asymmetry
