Hygroscopic Tablet Suspension Design to Maximize Sorption Surface Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dehumidifiers with hygroscopic agents in tablet form face challenges in maximizing the sorption surface area, leading to reduced moisture absorption efficiency due to surface coverage by holding devices, which impairs the sorption process.
Innovation Solution
A dehumidifier design featuring a hanging device that allows almost the entire sorption surface of the tablet to be exposed to room air, utilizing a thorn-shaped hanging means or mandrel to minimize contact area and enhance ventilation, thereby increasing the free sorption surface and absorption rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holding device with base or holding frame is used to support the tablet, then the tablet is securely held in place, but the surface of the tablet is covered and the free sorption surface is reduced
Solution Approach 1:
The invention extracts the harmful function of the holding device by removing the base and holding frame that cover the tablet surface. Instead, a hanging means is introduced that supports the tablet from above without contacting the sorption surface, thus taking out the conflicting element and resolving the contradiction between stable holding and maximum sorption surface area.
Solution Approach 2:
The holding function is moved from a horizontal support structure (base/frame) to a vertical suspension system (hanging means). This dimensional change allows the tablet to be held securely in space without any part of its surface being covered, as the hanging means interacts with the tablet from a different spatial dimension (top surface or through-hole) rather than from below.
2Reliability
If a holding device with base or holding frame is used to support the tablet, then the tablet is securely held in place, but the sorption rate is reduced due to impaired sorption
Solution Approach 1:
The harmful base and holding frame are extracted from the system and replaced with a hanging means that does not interfere with the sorption process. This removal of the conflicting element eliminates the impairment of sorption while maintaining tablet stability through the alternative suspension mechanism.
Solution Approach 2:
The hanging means acts as an intermediary element that provides the necessary holding function without directly interfering with the tablet's sorption surface. It mediates between the requirement for stable tablet positioning and the need for maximum sorption rate by providing support from a location that does not obstruct moisture absorption.
3Device complexity
If the tablet is placed on a base, then the device structure is simple, but almost the entire sorption surface is covered and unavailable for moisture sorption
Solution Approach 1:
The base is extracted from the device structure and replaced with a hanging means. Although this introduces a different structural approach, it eliminates the fundamental problem of surface coverage while maintaining structural simplicity through the use of a single suspension element rather than a complex base-and-frame assembly.
Solution Approach 2:
Instead of supporting the tablet from below (base), the invention inverts the support approach by hanging the tablet from above. This inversion fundamentally changes the spatial relationship between the holding device and the tablet surface, ensuring that the sorption surface remains fully exposed while the tablet is securely held in position.
