Designing Chindogu is about the gag. It is the art of the "un-useless" invention. But for the joke to land, the sketch needs to look plausible.
If the execution is messy, the viewer sees a bad drawing. If the execution is tight, they see a real product that just happens to be ridiculous.
The nightmare of radial perspective
Umbrellas are notoriously difficult to shade. You have multiple triangular panels radiating from a single point. Each panel sits at a slightly different angle in space.
Manually hatching these panels is a trap. You start with the right intent. By the third panel, your hand gets tired. Your line spacing drifts. The perspective starts to warp.
Shifting the focus with Diagonal Lines
We used the Diagonal Lines Tile to solve the consistency problem. Instead of drawing every individual hatch mark, we placed the tile under the sketch.
The tile maintains a perfect 45-degree pitch. By rotating the page or the tile slightly for each panel, you get uniform shading without the mental fatigue of manual hatching.
Uniformity creates the illusion of form
The human eye is sensitive to patterns. When the line spacing is perfect, the brain stops looking at the lines and starts looking at the shape.
The Diagonal Lines Tile provides a "mechanical" feel. This is vital for industrial design sketching. It makes the umbrella canopy look like a manufactured textile rather than a series of shaky hand-drawn marks.
Where to use this
• Parachutes and kite sails
• Collapsible tent structures
• Folding hand fans
• Accordion-style bellows on machinery
• Pleated fabric details on footwear
Anywhere a repeated pattern defines the material.
Try this in your next sketch
How do you balance the absurdity of a concept with the technical precision of the sketch?
What are SketchTiles
SketchTiles are physical texture stencils built for designers, by designers. Place a tile under your page, trace with any pencil or marker, and the pattern transfers onto your sketch. Each set includes four double-sided tiles, etched with eight precise patterns: Diagonal Lines, Crosshatch, Isometric Dot Grid, and Hexagonal Grid.

SketchTiles are available as The Essentials Set and the Essentials Complete Set. Shop on Amazon.
