At some point, every engineer has to assess their design's durability, plan for replacement components, or figure out why something failed.

All of these situations are a part of working with spring components. ... Or are they?

Gas springs and their close cousins are abundant in many industries and applications. From overhead bins in airplanes, and from cargo doors to armored vehicle doors, industrial gas springs have a variety of applications. 

Heavy-duty gas spring hinges may already be installed on your product. Over time, the performance of those hinges can decline as the strength of the gas spring weakens across the product’s lifespan.

Some lids close gently. Others seem to wait until your hand is nearby, then drop like a trap. 

From the retractable keyboard tray you use at work to the cupboard doors in your kitchen, hinges are a part – often unnoticed – of everyday life. 

Sometimes, they take on bigger applications, such as industrial refrigerator door in the restaurant kitchen or the counter pass-through at a store.

In these more demanding scenarios, selecting the appropriate type of hinge, whether it's robust lid supports or adaptable gas spring hinges, becomes a significant factor in maintaining functionality and longevity.

When it comes to weight and motion control, developers certainly have their options. Two of the most popular options in high-stress, high-performance applications are gas springs and counterbalance spring hinges. Like with many other competing technologies, there’s a debate over which is the better value.

The user experience for a product with a heavy lid or cover can range from awkward to annoying to downright dangerous.

Picture holding an industrial toolbox lid in place while reaching in one-handed, maybe twisting your back in the process. Or what if it comes down suddenly when your arm or fingers are in the way? The bruises won't be pretty, and the damage might be much worse.

This is why many designers add gas spring lid supports to their lid design. Others lean toward using counterbalance spring mechanisms or other mechanical spring solutions.

Modern product design is heavily influenced by motion control. Many of today’s flashy or high-end products take advantage of innovative hinge mechanism design to stand out from the crowd.

The most durable and versatile products can turn out to be intimidating to the user if the wrong type of heavy-duty hinges are used. Ask anyone that lifts heavy lids all day -- spring-assisted hinges are necessary for the safety and efficiency of your entire staff.

There are many ways to make something go from point A to point B. Not all of them are great long-term solutions.
