1. Node Design Phase 1
Presentation
Presented by SD1/SD2/IV/SA

2. Our Goal
Node Design Pattern and
substantiating theory.
Utilised for the design of
all the Nodes throughout
the chassis.
Initial Node used
for Design

Assembly Options

12. Benefits of
Modular Eyelet
Node Design
● Reduced Number of components
● Less Materials = Reduction in weight
● Reduction in weakness points (less thin members)
● Modularisation means less print patterns
● Easier assembly
● Looks slick

13. Extensions of
Modular Eyelet
Node Design
● Locking teeth between surfaces
● Securing end-cap positions with locking pins
● Addition of a design for irregularly angled joints
● Hollow out solid material within stress / strain limits
● Determine best method for securing frame rods
within end-caps

14. What’s Next?
● Stress strain Testing
● Investigate concept extensions
● Investigate material options and printing techniques
● Incorporate into frame design file and test rigidity
● Iterate
● Iterate
