Design for Environment - Coursework Example A power screw attached to the motor driver rod is expected to have sufficient strength and resistance to force. These properties ensure no undesired movement from the user and bone regeneration forces occurs. The motor will have to be small enough to remain inside the device. Addition of load bearings to the device ensures that the user can exert full weight on the device without failure. These drivers entail both internal as well as external factors. This device, being expected to be implantedin patients body, need to meet all the compatibility requirements. Some of the expected goals of this design include: The specification of the required rates of bone lengthening will be required. The device will then be adjusted accordingly. The self-locking provision for the device ensures that rods do not return. The power screw provides the lengthening force. The device will be designed with steel roads with smooth surfaces as well as edges. This will, therefore, eliminate any physical injury on flesh as well as bone contact walls. The device’ moving parts will be internally fitted to avoid injury. Titanium-steel alloy, being un-reactive, means that no toxic substances resulting from reactions will be released. These reactions usually occur as electrochemical dissolution. Release of any toxic substance could cause pain (Edwards, 1996). As earlier stated, the device is to have smooth surface and edges to avoid injury. Since the device is to beembedded in thebody, the points of connection of the two rods should be made airtight. This will ensure that the device’s inner environment is separated from the body fluids avoiding any possible contamination.Corrosion of implanted metals in human bodies has been a major challenge. The device being made of titanium-steel alloy avoids any possibility of corrosions. Suitable fixing attachments will also be designed. They will be
