Study on Personalized Customization Method of Mattress Hardness Based on Spinal Alignment
Since individual differences of users affect the comfort of the mattress,in order to determine the optimal hardness configuration of the shoulder and back support area,waist support area and hip support area of the mattress for users of different body types,so that the spinal alignment of the human lying on the back is close to the natural standing spine curve and the spinal alignment of the side lying is close to the straight line.In this paper,a personalized mattress hardness customization method based on the spinal alignment of human lying posture is proposed.Firstly,the fit and straightness deviation indexes were defined to evaluate the spine morphology of supine and lateral lying,and then the hardness distribution characteristics and adjustment scheme of mattress were analyzed.Then,the hardness of each section of the mattress is adjusted according to the individual's natural standing posture spinal alignment as a reference value,so that the hardness of the three sections of the mattress can meet the supine and lateral human spinal alignment close to the natural curvature.The results show that after the targeted adjustment of the spring hardness of different zones,the results can be achieved in a limited number of times,and the most suitable mattress hardness parameters for different subjects are determined.Therefore,it is effective to customize the mattress configuration and the hardness of each zone based on the user's natural standing spinal alignment and lying spinal alignment.
