Solution Overview

Problem

Traditional shisha devices suffer from unwanted debris and liquid contamination in the airflow path, necessitating frequent cleaning and affecting user experience.

Innovation Solution

The shisha device incorporates a trough in fluid communication with the capsule cavity, designed to collect debris and liquid aerosol former through its larger upstream cross-section, preventing contamination of the airflow path and facilitating easy cleaning.

VSEngineering Contradiction Analysis

1Ease of operation

If traditional shisha devices are used without a debris collection mechanism, then the device structure remains simple, but unwanted debris and liquid contaminate the airflow path requiring frequent cleaning

Engineering Contradiction:
Improvecleaning frequencyVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the debris and liquid from the airflow path by introducing a separate trough component. The trough is positioned to receive debris and liquid aerosol former from the capsule, preventing these contaminants from entering the airflow path. This separation allows the main airflow system to remain clean while the trough collects all contaminants in one location for easy disposal.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The trough acts as an intermediary element between the capsule and the airflow path. It intercepts debris and liquid aerosol former that would otherwise contaminate the airflow, providing a buffer zone that protects the breathing path from contamination while maintaining the overall device structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a trough is added to collect debris and liquid, then contamination of the airflow path is prevented, but the device complexity increases

Engineering Contradiction:
Improveairflow qualityVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device is segmented into distinct functional zones: the capsule housing area, the trough for debris collection, and the airflow path. This segmentation allows each component to perform its specific function independently. The trough is positioned downstream of the capsule and upstream of the airflow path, creating a clear functional separation that maintains airflow quality while managing debris.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The trough utilizes the vertical dimension by positioning it below the capsule airflow path. Debris and liquid aerosol former fall downward into the trough due to gravity, while the breathable airflow continues horizontally through the device. This dimensional separation allows both functions to coexist without interfering with each other.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
