Nested Tissue Dispenser Structure for On-Demand Disinfectant Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tissue storage and dispenser models fail to effectively preserve hygiene, especially in health and service sectors, where the use of organic liquids for pressed tablet tissues does not adequately address the need for disinfection and antibacterial solutions.
Innovation Solution
A personal compressed tablet tissue storage container and dispenser with nested cylinders and a liquid reservoir system, where the liquid reservoir is initially isolated from the tissue reservoir but allows liquid absorption upon pressure, using organic scent, water, disinfectant, or antibacterial liquids, and featuring a flexible lower cover that transitions from concave to convex to facilitate liquid absorption by the tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If currently known tissue storage models are used, then the structure is simple, but the hygiene preservation capability is insufficient
Solution Approach 1:
The device is divided into separate functional modules: a liquid reservoir chamber containing disinfectant/antibacterial liquid, a tissue tablet chamber, and a dispensing mechanism. This segmentation allows the liquid and tissue to remain isolated until needed, preserving hygiene while maintaining manageable structural complexity
Solution Approach 2:
The liquid reservoir is nested within the main body structure, and the tissue tablet is nested within the liquid reservoir chamber. This nested arrangement maximizes space utilization while keeping the overall device compact and the structure manageable
2Reliability
If liquid reservoir is always in contact with tissue reservoir, then liquid absorption is immediate, but hygiene is compromised
Solution Approach 1:
The liquid reservoir is pre-filled with disinfectant or antibacterial liquid before use. The tissue tablet is pre-positioned in the chamber. When needed, the user simply presses the tissue tablet, which automatically initiates the liquid absorption process without requiring manual liquid application
Solution Approach 2:
The lower cover is designed to be flexible and deformable, transitioning from a convex state (isolating the liquid) to a concave state (allowing liquid contact) in response to user pressure. This dynamic behavior enables automatic liquid absorption only when needed, maintaining hygiene while ensuring functionality
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 solution provides a practical and hygienic means for health institutions by ensuring that tissues absorb disinfectant or antibacterial liquids upon use, enhancing hygiene and practicality in sectors such as hospitals and tourism.
Implementation Method 1
the lower cover (2B) is made of a flexible material and is capable of transitioning from a convex state to a concave state, thereby causing the liquid to enter the tablet tissue reservoir (6) and be absorbed by the tissue (12)

AI summary
A pressed sanitary tissue receptacle and dispenser comprised of a main body which defines nested inner and outer housing walls. The outer housing wall houses a quantity of liquid which is adapted to initially be isolated from a volume defined by the inner housing wall which houses the dry tissue. In one embodiment, the inner and outer housing walls are covered on their lower ends by a lower cover, and the upper ends of the inner and outer housing walls are covered on their upper ends by an upper cover. The upper cover may be a foil sheet. The liquid is permitted to enter the volume defined by the inner housing wall and become absorbed by the tissue upon the exertion of force on the upper cover, which causes the tissue to press against and deflect the lower cover in such a manner as to cause the lower cover to dislodge from sealing engagement with the inner cylinder.
