Liquid Dispensing Device Segmented Applicator Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing applicator devices for dispensing liquids often suffer from permanent deformation during use, contamination risks, and limited versatility in application, particularly when handling different liquids and substrates.
Innovation Solution
A device featuring a container with a closed proximal end and an open distal end, equipped with an applicator head and a receptacle for holding elements, allowing for easy attachment and detachment of applicator heads, and incorporating a shaking mechanism for mixing, along with a feed system that includes multiple feed openings and a filling opening, suitable for various liquid types and substrates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the container walls are made flexible to allow deformation during dispensing, then the device can adapt to different application surfaces, but the container may suffer from permanent deformation and loss of structural integrity
Solution Approach 1:
The device is divided into separate functional components: a rigid container for liquid storage and a separate applicator head with flexible elements for dispensing. This segmentation allows the container to maintain structural integrity while the applicator head provides surface adaptability through its flexible foam or felt components that can conform to different application surfaces.
2Device complexity
If the applicator head is fixed permanently to the container, then the device structure is simplified, but the device loses versatility in handling different liquids and substrates
Solution Approach 1:
The applicator head is designed with a dynamic attachment system that allows it to be easily removed and replaced. The retaining element with receptacle provides a simple mechanical connection that can be quickly detached and reattached, enabling the device to adapt to different liquids and substrates without complex reconfiguration while maintaining structural simplicity.
3Adaptability or versatility
If the applicator head can be easily detached and replaced, then the device versatility is improved, but the device complexity increases due to additional mounting components
Solution Approach 1:
The attachment system uses a simple retaining element with a receptacle that provides easy detachability through basic mechanical movement. This dynamic connection allows quick replacement of the applicator head while minimizing the number of mounting components, achieving ease of replacement without excessive complexity.
4Area of stationary object
If multiple feed openings are provided for liquid supply, then the liquid dispensing coverage is improved, but the risk of contamination increases
Solution Approach 1:
The feed openings are strategically positioned and sized to optimize liquid distribution across the applicator head while minimizing exposure to contamination. The local quality of the feed opening arrangement ensures adequate coverage area while maintaining controlled access points that reduce contamination risk compared to larger, more exposed openings.
