Helix-C-Sketch in Engineering Design

This study improves the C-Sketch by elevating the sketch process from the group to the group after the individual sketch. This study was conducted between students from the Singapore University of Technology & Design (Singapore) and Mahidol University (Thailand), who have different backgrounds and problem-solving skills. The class had six groups, each consisting of 3 students from Singapore and 3 from Thailand. After the C-Sketch in individual group is completed, one of the designs is selected and passed to another group for group sketch processing. It is worth mentioning that no conversation and idea exchange is allowed between groups. Each group must improve the design without consulting another group. It is regarded as a Helix-C-Sketch. Most (more than 90%) of the students agreed that Helix-C-Sketch improves the conventional C-Sketch significantly and preferred Helix-C-Sketch.
