Dual Reservoir Coating Applicator with Segmented Brush and Point Tips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional precision coating applicators are inadequate for accurately applying coatings to narrow areas, such as scratches, due to their broad application capabilities, and existing solutions for narrow areas are not versatile enough for both broad and narrow surface applications.
Innovation Solution
A dual precision coating applicator device with a first reservoir for a color coating composition, including a primer or touch-up paint, and a second reservoir for a clear top coating, featuring a point applicator and a brush applicator, allowing for precise application to both broad and narrow surfaces with a bulbous second reservoir design to prevent spillage and a deformable agitator for mixing the coatings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a small brush is used for applying coating, then the applicator is desirable for broad area application, but it is not accurate enough for narrow area application
Solution Approach 1:
The applicator is divided into two separate applicator tips: a brush tip for broad area application and a needle tip for narrow area application. This segmentation allows each tip to be optimized for its specific function, resolving the contradiction between broad coverage and precision application.
Solution Approach 2:
The single applicator device incorporates multiple functions by including both brush and needle tips, along with two reservoirs for different coating compositions. This multi-functionality allows the same device to handle both broad and narrow area applications, eliminating the need for separate tools.
2Manufacturing precision
If a precision applicator with needle or elongated tube is used for narrow areas, then application precision is improved, but versatility for broad area application is reduced
Solution Approach 1:
The applicator incorporates two distinct tip types (brush and needle) that can be interchanged, allowing the user to select the appropriate tip for the specific application task. This segmentation maintains precision for narrow areas while adding versatility for broad areas.
Solution Approach 2:
The dual-tip design with both brush and needle applicators in a single device provides universality, enabling the same applicator to perform both precision narrow area work and broader coverage applications, thus resolving the versatility limitation.
3Device complexity
If a single reservoir design is used, then device complexity is reduced, but the ability to hold different coating compositions is limited
Solution Approach 1:
The reservoir system is segmented into two separate reservoirs: a first reservoir for color coating composition and a second reservoir for clear coat composition. This segmentation allows each reservoir to be dedicated to a specific coating type, preventing contamination while maintaining a relatively simple overall device structure.
Solution Approach 2:
The second reservoir is designed with a bulbous shape that nests within or alongside the first reservoir structure. This nesting arrangement accommodates two reservoirs in a compact configuration, minimizing device complexity while enabling storage of different coating compositions.
4Object-generated harmful factors
If the second reservoir has a larger diameter than the body, then spillage prevention is improved, but device dimensions increase
Solution Approach 1:
The bulbous second reservoir is nested within the overall applicator structure, with its larger diameter portion contained within the body housing. This nesting allows the reservoir to have sufficient volume for spillage prevention while keeping the external device dimensions compact and manageable.
Solution Approach 2:
The second reservoir utilizes a bulbous three-dimensional shape rather than a simple cylindrical form. This dimensional change allows the reservoir to maximize internal volume for spillage prevention while maintaining a compact external profile that fits within the applicator body.
