Bruise prevention apparatus

AG Ibrahim

Abstract


The work employs the fundamental principle of elasticity in putting together an apparatus comprising a network of both spiral and helical springs attached to an aluminium frame and embodied in a padded cotton fabric. Hookes law provided the theoretical guide for the choice of spring constant for both spiral
and helical spring as 23.33Nm-1 and 7.78 Nm-1 respectively. A prototype was designed using the Sweet Orange (citrus cinensis) as a case study. At the height of 5.9m ± 1m, the spiral and helical springs effectively played the role of cushioning effect and rebound prevention respectively.
