Liquid Applicator With Integrated Excess-Liquid Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for applying liquids of varying viscosities often require separate removal cloths to address excess application, which can be inconvenient and lead to suboptimal cleaning due to lack of availability.
Innovation Solution
A device with an integrated removal device featuring a microfiber cloth for absorbing excess liquid, detachably connected to the housing, allowing for easy replacement and adaptation to liquid viscosity, and a bayonet lock mechanism for flexible application and removal units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an integrated removal device is added to the application device, then the convenience and completeness of the device is improved, but the device complexity increases
Solution Approach 1:
The patent combines the application device and removal device into a single integrated unit. The removal device includes a removal element (such as a cloth or sponge) that is integrated into the housing structure, allowing both application and removal functions to be performed with one device. This merging eliminates the need for separate cloths or tools while maintaining operational convenience.
Solution Approach 2:
The integrated device performs multiple functions: the valve unit meters and dispenses liquid through the application unit, while the removal device simultaneously provides the capability to remove excess liquid. The housing accommodates both the reservoir for liquid storage and the removal element, creating a multi-functional device that addresses both application and removal needs in a single unit.
2Adaptability or versatility
If a detachable outer part with microfiber cloth is used, then the adaptability and ease of replacement are improved, but the device complexity increases
Solution Approach 1:
The removal device is segmented into a detachable outer part that can be separated from the main housing. This outer part contains the microfiber cloth or removal element and can be independently removed and replaced. The detachable connection allows users to swap out worn or saturated removal elements without discarding the entire device, enhancing adaptability while maintaining a relatively simple connection structure.
3Ease of operation
If the removal device is positioned on the side of the housing opposite the valve unit, then the ease of operation for liquid removal is improved, but the device complexity increases
Solution Approach 1:
The removal device is positioned on the side of the housing opposite the valve unit, utilizing the third dimension (lateral arrangement) rather than stacking components vertically. This spatial arrangement allows the removal element to be easily accessible from the outside of the housing, enabling users to perform removal operations without disassembling the device or reaching into confined spaces. The lateral positioning simplifies the operational workflow while maintaining a compact overall structure.
