Humidity-Stabilizing Device Using Tap Water Evaporation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing humidity-stabilizing devices for smoking materials, such as cigars and dried herbs, often require distilled water and are not adaptable for maintaining specific relative humidity levels, leading to issues like mildew and mold due to inadequate or excessive humidity.
Innovation Solution
A humidity-stabilizing device with two internal compartments separated by a vapor permeable barrier, using silica gel beads that can be rehydrated by evaporation from an absorbent material, allowing the use of ordinary tap water and maintaining optimal relative humidity levels between 45% and 70% without the need for distilled water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silica gel beads are saturated with distilled water, then humidity control is achieved, but the complexity of operation increases due to the requirement of distilled water
Solution Approach 1:
The patent introduces an intermediary substance (salt solution or absorbent material) that mediates between the distilled water and silica gel beads. This intermediary allows the beads to be charged with humidity control properties without direct contact with distilled water, thereby simplifying the charging process while maintaining reliable humidity control.
Solution Approach 2:
The patent changes the parameter of water purity requirement from 'distilled water only' to 'tap water with salt solution or absorbent material'. This parameter change simplifies the operation by allowing the use of readily available tap water instead of requiring distilled water, while still achieving effective humidity control through the intermediary substance.
2Reliability
If humidity is increased to maintain freshness, then flavor and potency are preserved, but mildew and mold may develop
Solution Approach 1:
The patent changes the humidity control mechanism from one-way (absorbing or releasing) to two-way control by using salt solution or absorbent material with silica gel beads. This allows the system to automatically adjust humidity levels within the optimal range (45-70% RH), maintaining freshness while preventing conditions that lead to mildew and mold.
Solution Approach 2:
The salt solution or absorbent material provides a feedback mechanism that responds to humidity changes in the environment. When humidity drops, the intermediary releases moisture to the beads; when humidity rises, the beads absorb excess moisture. This automatic feedback control maintains humidity within the safe range, preventing both drying out and mold growth.
3Reliability
If humidity-stabilizing devices are designed for specific RH levels, then optimal storage is achieved, but adaptability to different smoking materials is reduced
Solution Approach 1:
The patent creates a universal humidity control device that can serve multiple smoking materials (cigars, loose tobacco, dried herbs) with different RH requirements. The salt solution or absorbent material acts as a universal charging medium that works with silica gel beads to provide adaptable humidity control, eliminating the need for material-specific device designs.
Solution Approach 2:
The patent introduces dynamic adaptability through the salt solution or absorbent material system. The intermediary substance allows the device to dynamically adjust to different humidity requirements of various smoking materials by controlling the rate and amount of moisture transfer to the silica gel beads, making the device versatile for different applications.

AI summary
A humidity-stabilizing device for tobaccos or dried herbs that can be attached to the interior of a lid of a container to control relative humidity in the container. The device is a sealable container with internal compartments which are divided by a moisture-permeable barrier. The compartments separately hold moisture-absorbent material and humidity-stabilizing silica gel beads that together maintain the relative humidity of the container by action of evaporation and absorption. Because evaporate rather than water is employed in the humidification process, tap water rather than distilled water can be used to wet the moisture-absorbent material.
