Poka Yoke Visual Guide - Error-Proofing in Manufacturing & Design #3667126 (License: Personal Use)

The image illustrates the core principle of Poka Yoke (Japanese for “mistake-proofing”) using two colored blocks-one orange with a circular cutout, one blue with a star-shaped cutout-and corresponding parts. A circular token bearing the Chinese characters “先生” (meaning “Mr.” or “teacher”) sits in front, possibly indicating a labeled component or instructional context. The design ensures only the correct part fits its designated slot, eliminating human error in assembly processes.

This image is commonly used in lean manufacturing, quality control training, engineering education, and Six Sigma resources to visually explain mistake-proofing techniques. It matches user intent for understanding or teaching error prevention methods in production or design workflows.
