Braking History Essay

In a little over a hundred years since the automobile took hold of people’s imagination, technologies designed to make them accelerate faster and reach higher speeds have evolved with a fury. The brakes that were used to decelerate vehicles just over a hundred years ago (when cars were first invented) has evolved from plain wooden blocks to discs that are monitored by Anti-lock Brake Systems and Electronic Braking Distribution systems. The earliest braking system that used by vehicles consisted of nothing more than a block of wood and a lever system. The wood brake system worked fine in conjunction with early vehicles that were equipped with steel rimmed wheels. However, when the Michelin brothers started to replace steel rimmed wheels with rubber tires on most vehicles towards late 1890s, the wood block braking system just does not create enough friction with rubber. Since the need for a new method of braking was necessary in order to replace the old wood block braking system, inventors scrambled for new ideas. The French manufacturer Louis Renault took crude concepts of inventors before him and developed method: The drum based braking system. Basically, the system involved a single flexible stainless-steel band, wrapped around a drum on the rear axle. When the driver engaged the brake, the band would apply pressure to the drum and car to come to a stop. However, the drum braking system did have a number of problems. Since the drum brakes were external, the exposer caused a very rapid wear-out of the system and had to be replaced often. The band itself would sometimes unwrap on hills and proved to be very unsafe for the driver and passengers. Even though people came up with ideas to internally place the brakes, the era of mechanically-activated brakes was coming to an end. In 1918, A four-wheel hydraulic-brake system was invented by Malcolm Loughead. This system used fluids to transfer the force on the pressed pedal to the pistons and then to the brake shoes. In other words, it was the enhanced drum based system added with power support. The system quickly became popular due to the fact that it is much easier to operate and more effective than mechanical systems. Thus, it was adapted quickly by most of the automotive world. As the vehicles evolved to be heavier and faster, heat distribution started to become a major problem for the drum hydraulic-brake system due to increased friction. Disc brake system that was made from iron was invented to solve the problem. In order to stop the car, the brake pads are squeezed by a calliper which is pressured by the hydraulic, and then the discs are squeezed by the braking pads. Lining was placed on the braking pads to reduce the noise when the metal came in contact. This was as far as the braking system went in terms of mechanics. However, additional features such as the ABS (Anti-Lock Brakes), EBS (Electronic Braking system), and EBD (Electronic Braking Distribution) were implemented to further enhance the performance and safety of brakes. Since the industry was constantly seeking for replacements and innovations, achieving â€Å"the Minimum Winning Game† (MWG) is extremely important in not only the auto industry, but any high-technology ventures in general. By definition, the â€Å"Minimum Winning Game† is: Defining the first major market opportunity that is limited enough to provide a clear target for technology and product development efforts in the short-to-medium term, and sufficiently large that successfully pursuing it provides a foundation for long-term corporate development. Defining the â€Å"Minimum Winning Game† of any new breaking system is a difficult yet critical responsibility of management to keep the new innovation focused and able to learn from its ongoing efforts in the face of rapidly evolving technological and market uncertainties. Balancing a combination of the three drivers is essential in achieving the â€Å"Minimum Winning Game†. The drivers are: technology development, product development, and strategy development. Effectively pursuing these drivers will contribute positively, but allowing one to become the sole driver is likely to derail the venture from the path toward its Minimum Winning Game. Since braking technology is in such high-tech environments the pace of change is extreme. Instilling strategic discipline early on can prevent the new innovation of brakes to fall into the â€Å"Field of Dreams† trap: building the technology and it will become useful, while simultaneously increase the chances of its success.
