When I invent things, I always think about the balance that needs to be maintained between the different factors that drive the sales of a consumer product. I have to think about what the customer wants, and the final cost. I can always chose to make a new product stronger or have more features, but all of that changes the cost. I was just reading an article about using more metals in products. I have been learning about magnesium alloy frames and extruded aluminum parts. You do have to be careful in your designs as making something stronger might make it unable to be sold because it is too big and heavy. I could make a smartphone you could run over with a truck and it would survive, but it is not going to be comfy and slick looking in your shirt pocket. So, finding a balance is necessary. Say, building a smartphone that won’t crack if you sit on it wrong or drop it onto the pavement. It can survive that, but not the truck. That would be a decent balance.
That is just an analogy of how I think through the designs of the products I make. I like lightweight metals used in cases, shells and bodies of my products. I like how metal can be extruded, machined and welded together. I like the look and feel of metal. It conveys sturdiness in a way plastic cannot. Plus, metal does not have to look retro either. Although, that may be a design feature I am looking to have with some things. If I do use plastics in my designs, they are polycarbonates that can really take a beating and temperature fluctuations. My own personal opinion is that the American consumer is too used to everything being plastic. For example, why would I want a plastic shell on a toaster that is an appliance that heats things? It seems odd. I try to make my designs out of quality metal parts, and I use top quality metal manufacturing services to bring them to life.
