Automatic doors have become a staple in modern architecture, significantly enhancing accessibility and efficiency in various environments. At Total Automation LTD, we pride ourselves on our expertise in the design, installation, and maintenance of automatic doors. This blog delves into the origins of automatic doors, exploring the motivations behind their invention and the benefits they offer.
What Prompted the Invention of Automatic Doors?
The invention of automatic doors was primarily driven by the need to facilitate smoother, more accessible entry and exit in public and commercial buildings. Initially conceptualised to aid individuals with disabilities, automatic doors quickly gained popularity for their ability to streamline traffic flow and reduce energy consumption by minimising the time doors remain open [3] [4].
Improving Accessibility
One of the primary motivations for inventing automatic doors was to enhance accessibility for people with disabilities or mobility challenges. Automatic doors provide hands-free entry, benefiting those with limited mobility or strength. They offer easier access for wheelchair users, individuals using walking aids, and parents with strollers. Furthermore, they ensure compliance with accessibility regulations like the Disability Discrimination Act (DDA), promoting independence and equal access to public spaces for all individuals [5] [6].
Enhancing Convenience and Efficiency
Automatic doors were also invented to improve convenience and efficiency in high-traffic areas. They allow for seamless entry and exit without the need to touch door handles, which is particularly beneficial in busy environments like commercial buildings and airports. These doors help maintain smooth traffic flow and reduce congestion, eliminating the need to juggle bags or push open heavy doors. Their hands-free operation also enhances the user experience by providing a more convenient and hygienic entry solution [6].
Energy Efficiency
Another significant factor driving the invention of automatic doors was the potential for energy savings. Automatic doors help maintain consistent indoor temperatures by minimising heat loss and preventing doors from remaining open for extended periods. This reduces the strain on heating and cooling systems, leading to improved energy efficiency and lower utility costs for buildings. By automatically closing after entry or exit, these doors contribute to a more energy-efficient environment [7].
Hygiene and Safety
The invention of automatic doors also addressed hygiene and safety concerns. Touchless operation reduces the spread of germs and viruses through high-touch surfaces, an essential feature in today’s health-conscious world. Safety features, such as sensors that prevent doors from closing on individuals, reduce the risk of accidents. In emergency situations, automatic doors can be programmed to stay open for swift evacuations, enhancing the overall safety of the facility [7].
Historical Development
The concept of automatic doors has a long history. The first known automatic door was invented by Heron of Alexandria in the 1st century AD using heat and atmospheric pressure [3]. In 1931, the first modern automatic door using an optical device was patented by engineers at Stanley Works. Sliding automatic doors were invented in 1954 by Dee Horton and Lew Hewitt, initially using a mat actuator. By the 1970s, microwave motion detectors became common in automatic doors, followed by infrared sensors in the 1980s [3].
Conclusion
The invention of automatic doors was driven by a combination of factors, including the need for improved accessibility, convenience, energy efficiency, and safety. As technology has advanced, automatic doors have become increasingly sophisticated, offering features like motion sensors, adjustable speeds, and integration with access control systems. Today, they play a crucial role in modern building design, enhancing the user experience and promoting inclusivity across various environments.
