Introduction to Design
Students discover the design process as they complete an instant design challenge to create an ankle foot orthosis. They learn thumbnail, orthographic, isometric, and perspective sketching as methods for communicating design ideas effectively without the use of technology. The use of a common measurement system is essential for communicating and fabricating designs. Students learn conversions between two measurement systems and apply measurement skills while dimensioning sketches. Students conduct a mechanical dissection in the lesson project to better understand how objects and parts interact while using sketches to communicate and document their findings.
Modeling and Statistical Analysis
In this lesson, students transfer a two-dimensional representation to a three-dimensional solid model with technology. Students study basic geometric shapes within a mathematical model and use combinations of geometric primitives to form more complex shapes. During the design project, students work in teams and apply the design process to create a puzzle cube. Students create a solid model using a computer-aided design (CAD) application and fabricate their design solution for testing. Students use a dynamic mathematics program to complete statistical analysis from their testing results to determine if their design met the criteria and constraints.
Design Challenge
Students use a simulation to better understand cerebral palsy prior to beginning their Design Challenge. Within teams, students brainstorm and select a design solution to the problem based on design requirements. They establish team norms, collaborate, and recognize that solving authentic problems involves interdisciplinary skills such as engineering, biomedical science, and computer science skills. Using the design process, students create a solid model of their design and make necessary design modifications based on peer feedback.
