Coating Feeding Container Ratchet Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating material feeding containers face challenges in accommodating larger amounts of coating materials due to the internal placement of female screw members and spring portions, which restrict the length of the container and hinder compactness.
Innovation Solution
A coating material feeding container design featuring a tubular container with a movable body and a female screw member, where a tubular member with a first projection and second projections forms a ratchet mechanism, allowing for relative rotation in one direction while restricting the other, enabling the container to be filled with longer materials and maintained compactly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the female screw member and spring member are disposed inside the container main body with the spring portion formed at an intermediate portion, then the impact can be absorbed, but the container cannot be filled with a larger amount of coating material
Solution Approach 1:
The spring member is extracted from the interior space of the container main body and repositioned to the exterior, specifically on the rear surface. This extraction eliminates the space occupation inside the container, allowing the coating material to be filled to the maximum extent while the spring member retains its impact absorption function externally.
2Reliability
If the spring member is disposed inside the container main body to absorb impact, then the reliability is improved, but the container cannot be made compact
Solution Approach 1:
The spring member is extracted from the interior arrangement and positioned on the exterior rear surface of the container. This repositioning reduces the internal space requirements and allows for a more compact overall container design while maintaining the impact absorption capability through the externally mounted spring mechanism.
3Quantity of substance
If the container is designed to accommodate longer coating material, then the quantity of substance is improved, but the device complexity increases
Solution Approach 1:
By extracting the spring member from the interior, the internal space is maximized for coating material storage without requiring complex internal structural modifications. The external positioning of the spring member simplifies the internal container structure, allowing straightforward accommodation of longer coating material with minimal increase in overall device complexity.
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 allows for a larger capacity of coating materials to be loaded while maintaining a compact size, securely protecting soft materials and preventing unintended retraction through the ratchet mechanism.
Implementation Method 1
The first projection has elasticity in a radial direction of the tubular member by a through-hole that penetrates the tubular member in a periphery of the first projection in the radial direction
Implementation Method 2
A first projection is provided on an outer surface of the tubular member. At least one second projection for engagement with the first projection in a rotating direction of the container rear portion is provided on an inner surface of the container rear portion
Implementation Method 3
a screw engagement action of the male screw and the female screw functions, attendant on relative rotation of the container front portion and the container rear portion, such that the movable body advances with respect to the female screw member
