Compact Viscous Material Dispenser Using Toothed Cutting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional viscous material dispensing devices are cumbersome and unwieldy due to their long and heavy design, making them difficult to use in tight spaces, and existing improvements have not effectively addressed the need for compact, lightweight solutions compatible with standard containers.
Innovation Solution
A compact viscous material dispensing device featuring a toothed cutting-pushing element that eliminates the need for a rod to push the container cap, allowing for a shorter and lighter design by cutting a slit in the container wall as the cap is pushed forward, enabling efficient dispensing of viscous materials from various sized containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rod is used to push the container cap forward, then the container can be effectively emptied, but the device becomes long and heavy
Solution Approach 1:
The patent removes the rod component from the device entirely. Instead of using a rod to push the cap, the invention extracts this function by having the cap pushed forward by the material pressure itself after the container wall is cut, eliminating the need for a long rod and thus reducing device length while maintaining container emptying effectiveness
Solution Approach 2:
The invention segments the container wall by cutting a longitudinal slit, which divides the container structure. This segmentation allows the cap to be pushed forward independently by material pressure through the cut wall, eliminating the need for a continuous rod structure and enabling a more compact device design
2Ease of manufacture

Solution Approach 1:

Instead of using a rod to push the cap, the invention extracts this function by having the cap pushed forward by the material pressure itself after the container wall is cut, eliminating the need for a heavy rod and thus reducing device weight while maintaining container emptying effectiveness
Solution Approach 2:
The invention enables the container cap to push itself forward using the pressure of the viscous material being dispensed. The material pressure that naturally occurs during dispensing is harnessed to move the cap forward after the wall is cut, eliminating the need for an external rod mechanism and reducing overall device weight
3Length of moving object
If the device is made compact by cutting the container wall, then the device length is reduced, but the container structure is compromised
Solution Approach 1:
The invention segments the container wall by cutting a longitudinal slit, which divides the container structure. This segmentation allows the cap to be pushed forward independently by material pressure through the cut wall, enabling a more compact device design while the cut wall provides the necessary structural modification for the compact mechanism to function
Solution Approach 2:
The invention converts the potential harm of compromising the container wall into a benefit by making a controlled longitudinal cut. This cut, which might seem to weaken the container, actually enables the compact design by allowing the cap to be pushed forward through the cut wall by material pressure, thus the structural modification serves the compact mechanism's needs

AI summary
A dispensing device (300) is provided that comprises housing (360) having a grooved base (320) and configured to accommodate a container (10); cutting-pushing element (40) that comprises cutting-pushing base (48) slidably held by groove (322), push plate (42), at least one blade (44) comprising a sharp edge (45), and at least one tooth (47). A force transmitting element (370) is further coupled to the cutting and pushing element base. Movement of the cutting-pushing element forwards, toward the nozzle (11), by employment of the force transmitting element, inserts the push-plate into the container, so as to push the viscous material (16) out of the nozzle, and cuts lengthwise the container. Moreover, movement of the cutting -pushing element backwards, away from the nozzle, by release of the force transmitting element, allows at least one tooth to engage and pull the container backwards into the housing.
