Material Dispenser Stabilizer for Slip-Free Tube Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held material dispensing devices face issues with the slippery movement of tubes within the device, leading to instability during the dispensing of viscous materials.
Innovation Solution
A cutting-pushing element with a stabilizer positioned between the blade and push plate, which includes a fork-like shape or a ring-like structure, assists in stabilizing the container during forward and backward movements, ensuring a stable backward movement and preventing free movement within the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional caulk gun uses a simple push rod mechanism, then the device structure is simple, but the tube moves unstably and slips within the housing during dispensing
Solution Approach 1:
The patent introduces a stabilizer as an intermediary component between the push rod and the tube. This stabilizer features a fork-like structure with teeth that engage with corresponding teeth on the tube, providing lateral support and preventing the tube from slipping or moving unstably within the housing during the dispensing operation.
Solution Approach 2:
The stabilizer extends the support function from the traditional one-dimensional linear push to a multi-dimensional constraint system. The fork-like structure with lateral teeth provides support in both the axial direction (pushing) and radial directions (stabilizing), effectively constraining the tube in multiple dimensions to prevent slipping.
2Length of moving object
If a push and cut device is used to eliminate the long rod, then the device becomes more compact, but the tube's movement becomes slippery and unstable
Solution Approach 1:
The stabilizer acts as an intermediary between the shortened push rod and the tube, compensating for the reduced structural support provided by the shorter rod. The fork-like structure with engaging teeth provides the necessary lateral stabilization that the shortened rod alone cannot provide.
Solution Approach 2:
The cutting-pushing element combines multiple functional components (push plate, blade, and stabilizer) into a composite structure. This composite design integrates the cutting function and the pushing function while adding the stabilizing function through the fork-like structure with teeth, achieving multiple objectives in a unified component system.

AI summary
A device for dispensing viscous material out of a container having a nozzle, and a movable cap comprises a housing to accommodate the container, and a cutting-pushing element that comprises a push plate, a blade having a sharp edge, and a base having a recess. A force transmitting trigger is coupled to the recess to force the cutting-pushing element to move forward and backward. The device further comprises an improvement that comprises a stabilizer positioned between the blade and the push plate to assist in a stable backward movement of the container within the housing.
