The Slammer of SledgeWhammer

It's the first Action Project of our second class, Design and Engineering. This class is a math, science, and of course, design based course. The first of two Action Projects, as there are 2 units (as opposed to the regular amount, three), has us recreating/improving upon a tool that we already decided to analyze during an external investigation at Home Depot, seeing why the tools were made and how they help. My fellow blogger MF and I decided upon the sledgehammer as it wasn't that practical for gardening, so it stood out (unknowingly deciding the tool for this Action Project). During this time of research, it was worth noting the weight and material of different sledgehammers, as well as the variety ni handles. Some hammers were cushiony, some where just plain steel, others had wooden handles, it was all so different for being the same exact tool. Certain struggles and obstacles with the design were finding out its size and how it would differ from the competition. At first, the idea was making it repetitively slam onto a surface, but then the problem was finding out how that would work. Overall, I was proud of the concept and enjoyed figuring out how to work out the different mechanics, innovating on every aspect we could. Just below you can find the rest of the information about the concept, and I hope you enjoy.

Now people of all ages are the intended consumer as it should have universal usage. Despite physical differences, anybody should be able to pick up a nifty sledgehammer and buy it for some good old fashion demolition without worrying about buying multiple types or a unique version. A tool that relies heavily on the simple machines; a lever, pulleys, wheel & axle— should be able to be universally used (interchangeable weights/hammers). And speaking of the lever, as one side rises, the other side lowers, so utilizing a counterweight was truly taken advantage of as we could have the sides alternate going up and down for efficiency through repetitive hammering. So unlike the common sledgehammer, our SledgeWhammer can be used by anyone, even a senior citizen.

Based on the interviews my fellow students and I did, our consumers (or at least gardeners) want easy tools that are comfortable and efficient. And since we empathize those of you who aren't as physically able as the average adult, we made a design that suits everyone. Now with the SledgeWhammer, we have a detachable sledgehammer that rests on a fulcrum, equal distance from its also interchangeable liquid counterweight (to make repetitive smashing). This lightweight frame of 24 pounds is small enough to fit inside of a minivan, and the cases containing the multiple hammerheads and counterweights are neatly packed. The liquid counterweight is intended to create a mirrored ripple-like effect that will create the equal and opposite reaction for every action the head of the hammer does. The hammer itself is lifted by a double pulley system that's controlled by a crank.

The SledgeWhammer won't be a hassle, as it's operated by a ratchet pulley system that utilizes a crank to raise the hammer and a release/lock button to start the swing (which might I add is behind the tool, and on the back of it, there's a strong, thick layer of plexiglass so you can see what you're demolishing!), or stop it when necessary. The crank is to the side of the frame pulling on an extremely dexterous tether which is attached to one pulley that redirects the tether to the ratchet pulley, which raises the hammer. But what if you don't need or want to utilize the whole SledgeWhammer? That's why the sledgehammer part is detachable, no need to roll the frame with you everywhere you go. All the parts of the hammer come in cases (alongside counterweights) so it's easier to transport, however these cases can get hefty sometimes, so don't underestimate the weight. On the other hand, since I mentioned the frame, it's supported by 4 large wheels that are friction-based to ensure that when the brakes are applied, the tool stays in place. The frame also has gaps for cost-efficient design when being built, and it utilizes triangles in its frame design for a sturdier build.

Lastly, the SledgeWhammer smashes the competition with its diversity in a single tool, as well as automated performance. And who even wants a regular sledgehammer when the SledgeWhammer is the coolest tool you'll ever own? It's like the best non-electric jackhammer anyone could ever ask for.
