NASA Langley Research Center has created a Composite Joint Connector that is structurally stable, when force is applied from multiple angles. The innovation on typical connector joints is that standard connectors are very strong against force applied on a single axis, but they are able to slide out of place when force is applied from a secondary axis. This new joint connector is made of lightweight durable materials, and is designed to minimize stress concentrations, increasing structural efficiency. Increased structural efficiency is a huge benefit of these new joints. Structural efficiency is the amount of force an object can withstand, typically measured by a tensile test, divided by the mass of the object. These joints are designed to maximize stability and force of attraction, while also minimizing material needed in manufacturing and the weight of the overall joint. This increased efficiency is widely marketable, as it doesn’t sacrifice any structural integrity, but is significantly more cost effective.The casing is a material able to be elongated under pressure, and expands in order to keep the inside screw secure. The outer and inner screw are connected by a wave pattern, with alternating ridges and valleys. The inside of the joint is a rather unremarkable screw, aside from its ability to navigate through both small threads of the screw and the larger wave-like pattern.

Design Review

Research for Innovation

IDENTIFY THE CRITERIA AND CONSTRAINTS: -What criteria and constraints should you consider as you create a new use for the technology? Citera:- Must be derived from a technology designed by NASA (Spinoff Technology)- Must be innovative- Must be made out of a material that doesn’t negatively impact the human body- Must restore limb to be fully functional- Must seal and hold bones together (more effectively than current commercial products)- The outer piece must either fit within the bone itself, or go over it as a sort of cast Constraints: - Cannot be too expensive- Cannot require too invasive of an operation (such as cutting through the entire length of a leg, when a smaller cut would be sufficient under older methods)- Must be safe - Must be effective on a smaller scale- Must be legally viable-What criteria will be the most difficult to meet? Why?For this design to be relevant and useful, it doesn’t solely have to function they way it is intended to. It also has to function better than other readily available products that fulfill the same purpose. It’s a matter of increasing efficiency, be that from a manufacturing standpoint (cost), or from a medical standpoint (patient health and satisfaction).BRAINSTORM POSSIBLE SOLUTIONS AND SELECT A DESIGN: -Describe, in detail, possible designs that met your criteria.Idea 1: The entire screw and cap is inserted into the bone. The largest advantage of this design is that is is completely contained within the bone, and this limits the risks to the rest of the human body, caused by having a foreign body present. The setbacks to this design would be that it would require a much larger operation, and would need more of the bone removed. The larger scale of the operation also increases the risk of unintended side effects, which could be as serve as nerve damage, negating the entire goal of restoring a limb to be fully functioning. Idea 2: The screw portion of the innovation, complete with custom ridges is inserted into the bone, and the cap or sleeve the screw is held goes outside the bone. The benefit of this design is that the operation would be smaller and safer. The flaws of this design are that it would be less effective, lacking direct contact between the screw and cap, which is concerning because increased efficiency is the entire appeal of this product from both a medical and marketing standpoint.-For your winning design, justify why it was selected over other designs.I chose idea 1, because it would be more efficient having the screw and cap touching and connected, instead of trying to work around the bone (like in Idea 2). The safety concern of requiring a larger operation is countered by the safety benefit of containing the device completely within the bone, limiting the risk of infection or autoimmune diseases.

    Nice idea! I really like it.
