Concept development of a modular product variant for electronic strength training machines through evaluation of biostatistical data

Abstract

The aim of this Master’s thesis was to develop a concept for a new product series that can co-exist with the current product series rather than cannibalize it. Furthermore, a modular product strategy should be satisfied to generate synergy effects in terms of material and production costs. The biostatistical data obtained from the software company milon Care is analysed to determine which changes need to be addressed for the current product series with respect to proper loading and adjustments for the user’s physiological training position (e.g. range of motion, seating height). The concept for the new product series is developed under the premise to satisfy at least the 95th percentile of all users. A function cost matrix was developed to display the component groups with the greatest cost reducing potential. The ideas and concepts for alternatives were evaluated through a feasibility study with the head of the mechanical R&D department and a cost reducing potential estimate with the head of the purchasing department. Finally, the implemented concepts were visualized for the machines Chest Press and Back Extension. It is estimated that for the batch 1 strength machine circuit a cost saving potential of 12.93% is achieved through the concepts for alternative components, structures and materials.
