Dual Diameter Cap With Integral Adjustable Swab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing applicators for liquid coatings and solvents are limited in reaching the bottom of containers, are not interchangeable between different container diameters, and require separate cleaning and storage, leading to issues like grime accumulation and potential loss.
Innovation Solution
A dual diameter cap with an integral and adjustable swab that fits standard quart and gallon containers, featuring concentric threads for compatibility and a swab that can be extended and adjusted for deep reach, integrated with the container lid for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate applicator is used to apply coating material, then the applicator can be removed for cleaning, but the applicator becomes separated from the container and may be misplaced or lost
Solution Approach 1:
The applicator is integrated with the container lid through a hinge connection, merging two previously separate components (applicator and lid) into a single assembly. This ensures the applicator cannot be lost or misplaced while still allowing it to be detached for cleaning by opening the hinge.
Solution Approach 2:
A hinge mechanism serves as an intermediary connection between the applicator and the lid, providing both retention (keeping the applicator attached) and accessibility (allowing detachment for cleaning). The hinge mediates between the conflicting requirements of secure attachment and easy removal.
2Ease of operation
If a fixed-length applicator is used, then the structure is simple, but the applicator cannot reach the bottom of deep containers
Solution Approach 1:
The applicator features an adjustable-length shaft that can be extended or retracted depending on the container depth requirements. This dynamic adjustment capability allows the applicator to reach the bottom of deep containers while maintaining a compact form when not in use, resolving the conflict between reach and simplicity.
3Adaptability or versatility
If a single-diameter lid is used, then the lid structure is simple, but the lid fits only one container size and not interchangeable between different diameters
Solution Approach 1:
The lid incorporates multiple concentric rings with different diameter openings, allowing a single lid to fit multiple container sizes. This multi-functional design enables the lid to serve as both a quarter-size container lid and a half-size container lid, achieving versatility without requiring multiple separate lids.
4Reliability
If the applicator is integrated into the lid, then the applicator cannot be lost, but the applicator cannot be cleaned separately
Solution Approach 1:
The applicator is segmented from the lid body through a hinge connection, allowing the applicator to be detached as a separate component for cleaning while remaining integrated during storage and use. This segmentation enables independent cleaning of the applicator while maintaining overall integration.
