Design and research on the posture-adjustable mannequin for chest-upand hunchbacked posture

The development of garment personalization has put forward diverse requirements for mannequins. In this paper, we present a garment mannequin that can continuously alter the body posture in response to changes in human body posture in the chest and back regions. This research is founded on an analysis of the patterns and ranges of movement in the mannequin's chest and hunchbacked motions. We segmented the mannequin into six modules: neck, front chest, back, left and right shoulders, and waist and abdomen. By employing stepper motors, we independently drive the front chest, back, and left and right shoulders to achieve the simulation and continuous adjustment of the mannequin's body posture for chest and hunchbacked positions. The comparison of the 3D scans shows that the mannequin fits well in several cross-sections with the corresponding body variations of real people, and the results of the real shirt also show that the shirt made based on the simulated hunchbacked body mannequin is significantly better than the standard shirt in terms of comfort and aesthetics for a person with a hunchbacked body posture. The body posture adjustable mannequin can replace multiple static mannequins, which can provide strong support for the business model of personalized clothing customization. Compared with the existing dynamic mannequin, it has the advantages of high relevance, simple structure and low production cost.
