INDN 252 Design Physiology
PROJECT 1
EXPERIMENT 1C:
ANATOMICAL TOLERANCE 15%
Measuring anatomical, physiological and material relationships. This experiment explores the relationship and complexity of design between anatomy and an artefact. Methods: casting, scanning/measurement, digital modelling, digital printing – Due 19th Aug & 6th Sept.
TASK Design issue: Measuring human size and placing tolerances for fit. Transformation method: Three digitally produced rings which are the minimum, maximum and ideal size. Procedure: Use casting and scanning methods (to be demonstrated) to measure the diameter of the ring finger (located between the middle finger and the little finger) on the right hand of yourself. Import the scan data to solid‐works as starting point to produce a series of rings using digital manufacture. Translate your recordings and concept into a digital file capable of being viewed by your tutor before they are sent for rapid‐prototyping production. The aim is to extend the range between the minimum and the maximum dimensions of the internal dimensions (ID) as much as possible and then determine and design the ideal size. In designing the rings the circumference size of each ring must be established and recorded. You are free to explore design issues i.e. Surface texture relationship to skin/ the ring as an aesthetic object; be very cautious of literal representation. Testing method: the measurement will only be valid if the rings meet the following requirements. • The smallest ring ‐ must be able to go over the second knuckle and then be removed again. (In house printing) • The largest ring ‐ must be able to go over the second knuckle and then be removed again and must remain on your hand in a downward position for 30 seconds. Your hand will be assertively moved during this period. (In house printing) • The ideal size ring ‐ must be able to explain how you arrived at the ideal size. (Shapeways printing) Main issues to consider: Accuracy that can achieve when measuring anatomical tolerances Accuracy that can be achieved in translation from feel to fit Potential to damage the finger during testing, cause swelling and give inaccurate results Other scenarios or test to which this type of method could be applied or adapted
Accuracy of the proposed testing method * Exploration of design qualities, sensitivity and performance in digital printing Assessment Criteria: • Accuracy and measurement • Translation of sensitivity • Craft and expression of tolerance *Highly important
