About PeriO Circinus Scriptorius

PeriO est circinus scriptorius multiplicis usus, quo circuli, arcus et lineae rectae describuntur. Radius duobus lateribus motis constituitur et in disco centrali ostenditur. Receptaculum silicium in medio positum calamos diversae magnitudinis accipit. Rotarum conversio longitudinem lineae ductae et angulum arcus metitur. Cum angulus inter duo latera centum octoginta gradus est, linea ducta recta est. Discus centralis verti potest, ut circuli leniter describantur. Bractea ex aluminio facta est ut pondus minuatur, nec acumen acutum requiritur.

Unique Properties: This is a multifunctional compass that can independently determine the radius. In addition to drawing circles, it can also draw arcs and straight lines. The length of the drawn line and the angle of the arc can be calculated by the rotation of the wheel. It reduces the volume of the compass and makes the process of using more safe.
Dimensions & Packaging: Width 45mm x Depth 21mm x Height 5.5mm
Tags: Portable, compass, perimeter circle, ruler, angle, safety
Production Technology: The shell is made of aluminum to reduce weight, while the center and pen contact parts and wheels are made of silica gel to increase friction.
Design Challenge: The challenge in this research is to study the principle of the perimeter circle and implement it on the product. For this challenge, we studied the relevant mathematical formulas. We made some 3D models for testing to ensure the models can draw a circle smoothly and verify the feasibility.
Research: We have studied the formula for the principle of determining a circle with three points, By using software to draw a schematic diagram, we can find a shape that can be combined with the principle. The pen inserted in the middle and the wheels on both sides constitute three points. We made some 3D models for testing to ensure the models can draw a circle smoothly and verify the feasibility.
Inspiration: We cannot directly determine the radius when using compasses, and it is inconvenient to adjust the compasses repeatedly when matched with a ruler. When drawing the arc, the angle of the arc cannot be determined, and the sharp part of the compass is also a hidden danger. Inspired by the perimeter circle command in Solidworks, we conducted key research and formula deduction on the principle of how three points determine a circle.
Project Duration: The project was started in September 2020 in Beijing and finished in November 2020 in Beijing.
Operation Flow: When in use, move both sides to adjust the radius, the radius is displayed on the disc, and the pen is inserted into the center to draw a circle. The middle insertion pen is made of silicone material, which can be applied to pens of different sizes. The length of the drawn line and the angle of the arc can be calculated by the rotation of the wheel. When the angle between the two sides is 180 degrees, the drawn line is a straight line. In addition, the disc in the middle can be rotated to make the process of drawing a circle smoother. The displayed number is always positive for the user to identify easily.
