Solution Overview

Problem

Existing devices for treating and storing cigars and other tobacco products fail to provide a controlled environment for maintaining specific humidity levels, as they rely on atmospheric moisture absorption, which is impractical and cannot detect the actual moisture level within the tobacco product, making it difficult to meet individual consumer preferences.

Innovation Solution

A handheld treatment device with a closable receptacle and a hollow needle for injecting fluid into the tobacco product, equipped with sensors to monitor and control humidity, temperature, and other parameters, allowing for precise conditioning of the smoking article.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If moisture is supplied by a moist sponge or hydrogel in a humidor, then the atmosphere in the humidor maintains a certain moisture level, but the actual moisture level in the tobacco product cannot be detected and controlled

Engineering Contradiction:
Improvemoisture level in tobacco productVSAvoiddetection of actual moisture level
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent introduces a sensor as an intermediary device that directly contacts the tobacco product to detect its actual moisture level. This sensor acts as a mediator between the tobacco product and the control system, providing real-time feedback on the true moisture content inside the product, thereby resolving the inability to detect actual moisture levels.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements a feedback control system where sensors continuously monitor the moisture level in the tobacco product and transmit this information to a controller. The controller then adjusts the moisture supply (via the sponge or hydrogel) based on this feedback, creating a closed-loop system that maintains precise moisture control according to detected actual conditions.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If a humidor uses atmospheric moisture absorption to condition tobacco products, then the storage environment maintains general humidity, but individual and precise moisture control for different tobacco products cannot be achieved

Engineering Contradiction:
Improveindividual moisture conditioningVSAvoidmoisture control system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the humidor into individual compartments or chambers, each capable of independently conditioning different tobacco products. Each compartment can have its own sensor and moisture control, allowing individual and precise moisture adjustment for each product type or even each individual product, thereby achieving adaptability without requiring an overly complex centralized system.

Inventive Principle:
Principle #1Segmentation

3Quantity of substance

If a needle is used to inject fluid into a cigarette, then the cigarette can be moistened, but the device becomes complex and is not suitable for cigars or other tobacco articles

Engineering Contradiction:
Improvemoisture contentVSAvoidinjection device structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent employs a dynamic needle mechanism that can automatically adjust its position, depth, and injection parameters based on the type, size, and moisture content of the tobacco product being treated. This dynamic adaptation allows the same device to effectively treat different products (cigarettes, cigars, etc.) with varying requirements, maintaining simplicity while achieving precise moisture control through automated adjustment rather than complex manual operation.

Inventive Principle:
Principle #15Dynamics
