Suspended Dehumidifier Tablet Structure for Higher Sorption Rate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dehumidifier tablets have a reduced sorption surface due to covering areas, which impairs their moisture absorption efficiency.
Innovation Solution
A tablet design with a hanging mechanism that allows almost the entire sorption surface to be exposed to room air, combined with a collecting container and ventilation system to enhance moisture absorption and prevent leakage, using hygroscopic agents like calcium chloride or magnesium chloride in a pressed tablet form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tablet is placed on a base or holding frame, then the tablet is securely positioned, but the covering areas of the tablet are impaired and sorption surface is reduced
Solution Approach 1:
The tablet is suspended in a hanging manner, transitioning from a horizontal placement on a base to a vertical hanging position. This dimensional change allows the tablet to be supported at its top surface while the bottom and lateral surfaces remain fully exposed to air, maximizing the sorption surface area without compromising positioning stability.
Solution Approach 2:
The tablet is extracted from the conventional base-supported configuration and repositioned to hang from the holding frame. This extraction removes the interference of the base covering the tablet surface, allowing the entire bottom and lateral surfaces to function as active sorption areas.
2Ease of operation
If a holding frame covers areas of the tablet, then the tablet is retained in position, but the sorption rate is reduced due to impaired surface availability
Solution Approach 1:
The holding frame is designed to engage with the top surface of the tablet in a vertical orientation, allowing retention without horizontal coverage. The tablet hangs vertically, enabling the holding frame to secure the tablet while leaving all lateral and bottom surfaces exposed for moisture sorption.
3Ease of operation
If the collecting container is open, then access is easy, but the solution can leak out and contamination occurs
Solution Approach 1:
The collecting container is equipped with a flexible lid that can be opened for access and closed for containment. The lid acts as a removable barrier that prevents solution leakage and contamination when closed, while allowing easy access when opened, thus resolving the contradiction between accessibility and leak prevention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design increases the free sorption surface area, leading to a higher sorption rate compared to conventional devices and prevents leakage by using a leak-proof collecting container and ventilation system.
Implementation Method 1
a tablet (300) consisting of a hygroscopic air dehumidifier and having a substantially cylindrical tablet body (301) with a sorption surface (302) provided on two opposite end faces and a jacket side
Implementation Method 2
a means for receiving the mandrel (111) is provided, which serves to suspend the tablet (300) in order to enable contact of almost the entire sorption surface (302) with the room air
Implementation Method 3
the collecting container (200) arranged below the holding device for receiving a solution

AI summary
The dehumidifier (1) has a holding device for holding a cylindrical tablet containing a hygroscopic air dehumidifying agent e.g. calcium chloride, and a collection vessel (200) arranged beneath the holding device for receiving a solution. The holding device has a suspension unit for suspending the tablet above the collection vessel. The suspension unit allows contact of virtually an entire sorption surface of a tablet body with the room air to enlarge the sorption surface area available for sorption of moisture from the room air. An independent claim is also included for a tablet containing a hygroscopic air dehumidifying agent for sorption of moisture from room air.
