What if your customer has put "ergonomic" on the wish list for the machine you're designing? What qualities should you be seeking in the components? Here are a few suggestions based upon OSHA principles for ergonomic design.
Look for handles that are smooth (as opposed to having grooves) so any size and shape of hand can use them. If the user's hand doesn't fit the grooves, it results in excessive pressure.
Use knobs and handles covered in soft material—they are more comfortable, provide a firmer grip and reduce slippage.
Design the machine so that operating components can be manipulated with the wrist in a straight position.
When precision is the requirement, choose components with grips in the 1/4" to 1/2" range. The smaller diameter prevents overexertion of fingers, knuckle joints, and hand muscles.
For operations that require force, look for components whose grips have handle or knob diameters that range from 1 1/4" to 2." This allows for fingers to wrap comfortably in a firm hold.
