Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a blank coloring substrate is used, then users can create marker artwork, but the substrate does not provide boundaries for guiding marker ink application for segmented or pixelated art effects
Solution Approach 1:
The substrate is divided into multiple discrete wicking protrusions that are spatially separated from each other. Each protrusion acts as an independent pixel element, allowing users to apply marker ink to specific locations without affecting adjacent areas. This segmentation enables creation of segmented or pixelated art while providing clear boundaries for ink application.
Solution Approach 2:
The wicking protrusions have localized hydrophilic properties that differ from the surrounding hydrophobic substrate. This local quality difference creates specific zones that attract and wick marker ink, providing visual and functional boundaries that guide users in applying ink precisely to desired pixel locations while preventing unwanted spread.
2Adaptability or versatility
If competitive heat-based products are used, then pixelated art can be created, but heat supervision by an adult is required
Solution Approach 1:
The patent replaces the thermal field (heat-based ink transfer) with a capillary action-based liquid wicking system. Marker ink is applied directly to the hydrophilic wicking protrusions where it is drawn in through capillary action, eliminating the need for heat application and associated safety supervision requirements while maintaining pixelated art creation capability.
Solution Approach 2:
The patent converts the potentially harmful heat-based process into a safe cold-process by utilizing the wicking properties of hydrophilic materials. The same capillary action that enables ink transfer without heat also provides a safer alternative that eliminates thermal hazards while preserving the desired pixelated art outcome.
3Manufacturing precision
If a hydrophobic base is used, then ink spread is controlled, but the base cannot wick the donor solution
Solution Approach 1:
The substrate features localized hydrophilic wicking protrusions embedded within or on the hydrophobic base. The hydrophilic regions selectively wick marker ink through capillary action, while the surrounding hydrophobic base prevents lateral spread of the ink. This local quality differentiation simultaneously achieves both ink absorption and boundary control functions.
Solution Approach 2:
The substrate combines hydrophobic and hydrophilic materials in a composite structure. The hydrophobic base material provides ink spread resistance, while hydrophilic wicking protrusions (made from different material or treated differently) provide controlled ink absorption. This composite approach resolves the contradiction between preventing ink spread and enabling ink uptake.

Function Achieved in This Case
Enables users to create pixelated art without heat supervision, using a simple method to apply marker ink safely and repeatedly on a specially designed 3D surface, with vibrant colors and easy cleaning.
Implementation Method 1
The substrate has been molded specifically with an array of small vertical flat-topped cylinders covering nearly the entire surface. The wicking substrate is typically molded or co-molded using two separate materials that will allow the protruding vertical cylinders to easily absorb the marker ink using a porous material.
Implementation Method 2
A hydrophobic base; and a plurality of hydrophilic columnar wicking posts coupled to and extending upward from the hydrophobic base, wherein the hydrophobic base is configured to resist wicking the donor solution wicked through the wicking post.
