Innovation Keynote – Safety Inventions

I was the innovation keynote speaker this week for the St. Louis Safety Conference on the topic of safety inventions. This is one of the most important industries for inventors. A great safety invention could save lives and ultimately change the world.

Inventors Spot Problems Others Miss

Inventors often spot problems that other people miss. So safety professionals are in a unique position to know what those problems are and come up with solutions for them that will solve their own problems. And also solve safety problems for millions of people around the world.

Most Important Safety Inventions in History

Many people would agree that the most important safety invention in history is the invention of sanitation. Clean water and waste removal has saved more lives than any other safety invention. It has more than doubled our life expectancy.

As early as 300 BC Ancient Romans devised a system of aqueducts to provide some citizens fresh running water. It was piped into homes and public fountains and baths. But the first septic tank wasn’t invented until 1860.

Today there are still hundreds of millions of people around the world who don’t even have access to clean water. But a simple solution was found in the Lifestraw. It has an advanced filter to get rid of almost all microbiological contaminants in order to make water safe to drink.

It was designed to help people who don’t have access to safe water and in emergency situations when water is contaminated. The Lifestraw adapted to the limitations of the situation. We don’t have to purify ALL of the water, but just enough for a person to drink.

Important Safety Inventions

One of the most important safety inventions in history is the three point seatbelt, invented by Nils Bohlin. The original seatbelt was invented to keep pilots in their gliders. The first patented seat belt was invented to keep tourists safe in taxis in New York City. Race car drivers were the first to wear seat belts to protect against serious injuries.

The three-point seatbelt protects both the upper and lower body. Like many inventions, his seat belt design was both simple and effective, saving millions of lives.

The invention process is always evolving and improving, so it makes sense that the seat belt design would too. Ford is now testing an inflatable safety belt that contains an airbag which would inflate on impact.

Invention of the Saw

The design of the hand saw is also changing. Many inventions go back pretty far in history. That’s how it is with the saw. Saws made of copper go back as far as 3100 BC but it’s Chinese engineer and carpenter Lu Ban who gets the credit for inventing the saw. He came from a family of carpenters, who didn’t have saws during that time period. They had to use axes to cut the wood, which was very time consuming.

The design of the saw is now evolving again. Portable band saws have always been heavy and bulky, requiring two hands to hold them steady. Lately, the size and weight of power tools has decreased because of the conversion from corded to cordless. This makes them capable of being held one-handed while dangerously steadying pipe in the other.

Rosendin Electric

Rosendin, the electrical contracting industry’s largest employee-owned firm, discovered that product improvements had an unexpected safety risk to its employees. They noticed that once the natural pipe resistance was gone as it was cut through. The saw would jerk downward until the operator could remove his fingers from the blade’s single trigger. This creates a risk of the saw striking the worker’s now free hand to reach across and under the moving blade. When you attempt to catch the falling piece of material, it results in injuries to the person using it.

Rosendin set out to find a solution to this safety risk, thinking if the saw required two hands to operate, the risk to employees would be greatly reduced. With two hands operating the saw, there would be no risk that one hand could come in contact with the saw blade while it was moving.

The company reached out to professional tool maker DEWALT about creating a new design. DEWALT designed and developed a new band saw, where two separate hands are needed to push dual switches before the motor will turn on in order to operate the band saw. The clever new safety invention is built so that users cannot outsmart or overide the dual switch safety feature.

Rosendin hopes to lessen workplace injuries and they are doing their part. They are already seeing a reduction in equipment-related injuries in the workplace.

Employees at work aren’t the only ones who could benefit from new safety inventions. Every year almost 10,000 children under the age of 2 are treated in the emergency room for crib related injuries. The most common cause of injury is usually caused by kids climbing out and falling on the floor.

They say that necessity is the mother of invention. In this case it was the father who came up with a safety invention for the safety of his son. Daniel’s young son was just starting to stand up and explore. But he couldn’t have predicted that his son would be able to climb out of his crib and hit the hard floor, injuring his face. After a brief ER visit, luckily he was able to go home. Many children sustain serious head and neck injuries because of these falls.

Daniel tried to find a product on the market that would help solve his safety problem and found that nothing existed. So he designed the DreamCatcher. A mat that is laid on the floor, with 8 separate, inflatable sections that can be configured to any nursery layout. Whether the crib is against one wall, two walls, or in the center of the nursery. DreamCatcher is like an airbag that surrounds your baby’s crib in case a baby is adventurous and climbs out. Daniel was able to solve his own safety problem and will solve a safety problem for many other parents out there.
