Black Ruler

Measuring an irregular angle of a corner tends to require several different tools to complete the task. To make the process more convenient, the team created a 'corner tool' that can measure the angle of any corner. A rhombus frame is set to a ruler with similar angles on opposite corners. To measure the angle, adjust the frame until it is flushed into the corner and the ruler will give the accurate measurement. The team also created an 'offset' tool that allows one to perfectly inscribe a smaller circle within a circle just by rolling the circular disc tool. Taking advantage of fixed principles, the designers from Wenzhou Business College and Lishui Yimu Creative Design found an innovative solution to performing tedious measuring tasks.
