Today's power tool batteries owe their basic design and operating characteristics to a pair of 18th century Italian engineers and a trio of 19th century French scientists.
Without rechargeable batteries, cordless tools would be useless. As battery technology evolves, power tool manufacturers are continually searching for ways to make screwdrivers and other fastening tools more powerful, more lightweight and more durable.
After engineering and work-method considerations have been addressed, personal protective equipment is the final step toward reducing the potential risk of ergonomic injury on the assembly line.
More and more manufacturers are using human modeling tools to simulate assembly tasks and evaluate ergonomic risks. The technology offers many advantages to manufacturing engineers.
Standing requires about 20 percent more energy than sitting, so assemblers who stand all day typically experience greater fatigue. Over long periods of time, standing can result in poor blood circulation in the feet and legs.
Repetitive motion injuries have been plaguing assemblers for many years. In September 1970 (three months before OSHA was established!), ASSEMBLY Magazine first reported on a new term called "ergonomics."
Ergonomic assembly requires adequate visibility and illumination of the work area. Products that support this include lights, magnifiers and vision systems.
