Dyson's obsession with engineering goes far beyond vacuum cleaners and high-tech hair dryers. To design a simple hair sectioning clip, the company invested over $2 million in research and development, using custom automated robotic rigs to test the mechanism more than 10,000 times to guarantee maximum durability and grip strength. Engineers studied hair physics to calibrate the exact tension needed to hold different hair types securely without slipping, snapping, or pulling on delicate strands. It is a striking example of how even the most basic everyday tools can be completely reimagined through precision testing and science.
