Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid applicator apparatuses are inadequate for simultaneously and efficiently applying liquids to noncontinuous and nonplanar surfaces, which are often difficult to reach.
Innovation Solution
A liquid applicator apparatus comprising a handle member, an applicator retaining member, and multiple liquid applicators that are rotatably displaceable and adjustable, allowing for simultaneous application of liquids to noncontinuous and nonplanar surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single liquid applicator is used, then the device complexity is low, but the productivity is insufficient for noncontinuous and nonplanar surfaces
Solution Approach 1:
The liquid applicator is divided into multiple independent applicators (first applicator, second applicator, etc.) that can be independently adjusted and rotated. Each applicator can be positioned at different locations and orientations to simultaneously cover multiple surfaces including noncontinuous and nonplanar surfaces, thereby increasing productivity without requiring a completely new complex device design
Solution Approach 2:
The applicators are made rotatably displaceable and adjustable, allowing dynamic repositioning during the painting operation. This enables the applicators to adapt to various surface geometries and maintain optimal contact with noncontinuous and nonplanar surfaces, improving application speed and coverage efficiency
2Productivity
If multiple liquid applicators are added to increase productivity, then the application speed improves, but the device complexity increases
Solution Approach 1:
The applicator retaining member is designed as a universal mounting structure that can hold multiple applicators in various positions and orientations. This single multi-functional retaining mechanism replaces what would otherwise require multiple separate mounting structures, thereby supporting high productivity while controlling overall device complexity
Solution Approach 2:
The multiple applicators are arranged and retained in a nested or compact configuration within the applicator retaining member. This allows the applicators to be positioned close together without excessive space requirements, reducing the overall structural complexity while maintaining the capability for simultaneous application to multiple surfaces
3Adaptability or versatility
If fixed position applicators are used, then the device complexity is low, but the adaptability to noncontinuous and nonplanar surfaces is poor
Solution Approach 1:
The applicators are equipped with rotatable and adjustable mounting that allows them to be dynamically repositioned to match the geometry of noncontinuous and nonplanar surfaces. This dynamic adjustability enables the system to adapt to various surface types (decks, shiplap, brick, etc.) while keeping the adjustment mechanism relatively simple through the use of basic rotational and positional adjustments
