Toothpaste Tube Rolling Mechanism for Complete Content Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holder devices for toothpaste and toothbrushes lack a mechanism to efficiently extract the contents from a toothpaste tube, as they do not incorporate a rolling mechanism to squeeze the tube.
Innovation Solution
A holder device with a base that includes a mating unit for stability, a stand for toothbrush storage, a cylinder with a channel for the toothpaste tube, and a rotatable shaft with a knob to roll the tube, allowing the entire contents to be squeezed out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional holder device with recess and nozzle is used, then the device structure is simple, but the toothpaste tube contents cannot be fully extracted
Solution Approach 1:
The patent introduces a dynamic rolling mechanism where the shaft can rotate within the cylinder to roll the toothpaste tube. This dynamic element transforms the static holder into an active extraction device, enabling the tube to be rolled and contents to be squeezed out completely through rotational motion.
Solution Approach 2:
The shaft acts as an intermediary element between the user's manual input and the toothpaste tube. By rotating the shaft, the user indirectly rolls the tube through the friction and contact between the shaft surface and tube surface, achieving extraction without directly manipulating the tube itself.
2Loss of substance
If a rolling mechanism is added to squeeze toothpaste tube, then all contents can be extracted, but the device complexity increases
Solution Approach 1:
The rolling mechanism is designed to be manually operated by the user through direct interaction with the shaft or cylinder. The system uses the user's own hand motion to perform the rolling action, eliminating the need for motors or automated mechanisms while achieving complete extraction of toothpaste contents.
Solution Approach 2:
The cylindrical shape of the shaft and cylinder provides a curved surface that naturally facilitates rolling motion. The circular geometry allows the toothpaste tube to roll smoothly along the curved surface, making the extraction process efficient and intuitive without requiring complex mechanical components.
3Stability of the object's composition
If the base is made stable with mating unit, then the holder remains stationary, but the base cannot be easily repositioned
Solution Approach 1:
The mating unit appears to be a simple, inexpensive attachment mechanism that provides temporary but effective stability. It can be easily installed and removed without damaging the base or support surface, allowing the holder to be repositioned when needed while remaining stable during use.

AI summary
A toothpaste and toothbrush holder assembly for storing a toothpaste tube and a pair of toothbrushes includes a base that can be positioned on a support surface. A mating unit is integrated into the base to engage the support surface thereby inhibiting the base from moving on the support surface. A stand is removably attachable to the base and the stand has a pair of supports each is integrated therein to store a toothbrush. A cylinder is provided that has a channel extending therethrough for having a closed end of a toothpaste tube inserted therein. A shaft is rotatably integrated into the cylinder to receive the closed end of the toothpaste tube. A knob is coupled to the shaft and the knob can be gripped by a user for rolling the toothpaste tube around the shaft.
