Helix-C-Sketch in Engineering Design Education


C-Sketch, or Concept Sketch, is a technique used in design thinking and collaborative ideation processes. It involves creating visual representations of ideas and concepts using simple sketches or diagrams. In conventional 6-3-5 C-Sketch setup, 6 person in a group generate 3 ideas each in 5 minutes. This setup could help to generate various ideas in a group, however, the influence of each member on getting innovative ideas will get saturated after second round of passing the sketch. This study improves the C-Sketch by elevating the sketch process between group to group after the individual sketch. This study was carried out between the students from Singapore University of Technology & Design and Mahidol University, Thailand, that have different backgrounds and very different problem-solving skill. There were six group in a class, where each group consists of 3 students from Singapore and 3 students 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 mentioned here that no conversation and idea exchange is allowed between group. Each group must improve the design without consulting another group. It is regarded as Helix-C-Sketch. Majority (more than 90%) of the students agreed that Helix-C-Sketch improve the conventional C-Sketch significantly and prefer Helix-C-Sketch.
