交叉引用
本申请要求于2021年06月09日提交的申请号为“202110642740.5”，名称为“足部矫正件的制造方法和足部矫正件”的中国申请的优先权，其全部内容通过引用结合于此。
技术领域
本申请涉及足部矫正领域，特别涉及足部矫正件的制造方法和足部矫正件。
背景技术
足部是人体运动系统的重要组成部分，正常情况下在运动过程中足与地面接触时，足部受力在不同运动阶段正常分布于足底各位置，为人体运动提供了动力，保障运动的顺利完成。但在缺乏锻炼、久坐、不良体态等常见因素的影响下，人体足部的足部结构异常越来越频发。
足部结构异常会导致足部受力不均，压力集中到足部某一区域产生疼痛现象，影响人体的活动能力，促使人体形成代偿机制来弥补由于足结构改变、足踝功能异常及缺失所导致的活动能力下降。例如，扁平足就是一种常见足部结构异常，其表征为足弓低平或消失。在站立、行走的时候，扁平足的足弓塌陷，会导致足部疼痛。
足部矫正件是足部结构异常的治疗器械，其能够调整足底负重点位置，转移足部受力集中点，对足受力异常部位提供受力补偿，合理分散足底压力，达到减小疼痛的效果，但是矫正过程中，用户会感觉非常不适。
因此，如何制造足部矫正件，以降低用户的不适感，是本领域亟待解决的技术问题。

在步骤210中，用户信息可以是实时进行测量的。或者，用户信息可以是预先存储在存储设备中，获取用户信息可以指调用存储设备中的用户信息。
步骤220，基于用户信息，确定至少两个矫正周期。
确定至少两个矫正周期，可以是确定具体的矫正周期数，且该矫正周期数为至少两个。在一些实施例中，至少两个矫正周期可以是两个、三个、五个、七个等数量的矫正周期。用户可以在不同矫正周期可以使用不同的足部矫正件，不同的矫正周期可以对应不同矫正幅度的足部矫正件。
在一些实施例中，具体的矫正周期数可以至少基于足弓信息来进行确定。例如，在确定足弓的最大高度后，当待矫正足部的足弓的最大高度与该待矫正足部的足弓的正常最大高度的差值较大(例如，差值大于预设差值阈值)，说明用户的足弓塌陷问题比较严重，则可以设置矫正周期数较多，如将矫正周期数设置为五个、七个等。又例如，当待矫正足部的足弓的最大高度与该待矫正足部的足弓的正常最大高度的差值较小(例如，差值小于或等于预设差值阈值)，说明用户的足弓塌陷问题比较轻微，则可以设置矫正周期数较少，如将矫正周期数设置为两个、三个等。在一些实施例中，可以基于用户需求信息来调节矫正周期数。例如，如果用户能够承受的矫正力度较小(即用户的疼痛阈值较低)，则增加矫正周期数。
在另一些实施例中，还可以通过图3所示的方法来基于足弓信息确定至少两个矫正周期，具体请参见的图3相关内容。
步骤230，基于用户信息，确定至少一个矫正周期对应的矫正件模型。

矫正件模型可以是设计人员基于用户信息(如足弓信息以及足长信息)在建模软件中进行人工绘制而构建的，也可以是计算机基于用户信息通过计算机内存储的相关算法来自动生成的，还可以是在计算机自动生成初步模型后设计人员进一步调整后得到的。仅作为示例，在获取矫正件模型的相关尺寸数据后，设计人员可以根据矫正件模型的相关尺寸数据在建模软件中等比例绘制出与对应的矫正件模型。或者，在获取足部矫正件的初始模型(如正常的鞋垫的模型)后，设计人员可以根据矫正件模型的相关尺寸数据在初始模型上进行调整，以获得矫正件模型(如矫正鞋垫的模型)。在一些实施例中，建模软件可以包括Rhino、Solidworks、Catia或UG等。
在一些实施例中，可以在数据库中预先存储多个适配于不同用户信息(如足弓信息以及足长信息)的矫正件模型，当获取到待矫正足部的用户信息时，可以从多个矫正件模型中挑选与该待矫正足部适配的矫正件模型。
在一些实施例中，矫正件模型可以基于矫正件的三维轮廓模型来确定。在一些实施例中，可以基于用户信息先确定矫正件的三维轮廓模型，再在三维轮廓模型的基础上，构建镂空网格，从而获得矫正件模型。确定矫正件模型的方法请参见图5的相关内容。

在一些实施例中，可以先确定一个周期的矫正件模型，在用户佩戴后再确 定其余矫正周期对应的矫正件模型。
在一些实施例中，步骤230可以包括以下步骤：基于用户信息，确定一个矫正周期对应的矫正件模型；获取矫正结果信息；基于矫正结果信息，确定其余矫正周期对应的矫正件模型。
在一些实施例中，可以基于足弓信息以及足长信息，确定一个矫正周期对应的矫正件模型。在一些实施例中，可以基于足底形状信息、足底压力信息、步态信息、足底损伤位置信息、全足信息、用户需求信息以及用户体重信息中的一个或多个来调整上述一个矫正周期对应的矫正件模型。矫正结果信息用于反映待矫正足部在穿戴足部矫正件至少一个周期后的矫正成果。矫正结果信息可以包括用户穿戴足部矫正件至少一个矫正周期后的足弓信息。在一些实施例中，矫正结果信息还可以包括用户穿戴足底矫正件至少一个矫正周期后的其他足底信息。在一些实施例中，矫正结果信息可以包括用户穿戴足底矫正件至少一个矫正周期后的足长信息、足底形状信息、足底压力信息、步态信息和足底损伤位置信息等信息中的一个或多个。在一些实施例中，矫正结果信息还可以包括用户穿戴足底矫正件至少一个矫正周期后的全足信息。足长信息、足底形状信息、足底压力信息、步态信息、足底损伤位置信息、全足信息、用户体重信息等的相关说明，请参见步骤210中关于用户信息的相关内容。
在一些实施例中，矫正结果信息还可以包括用户体验反馈信息，即用户穿戴后反馈的主观感受信息。例如，如果用户穿戴矫正件后感觉足弓高度过高，使用时不适感严重。此时，可以基于该用户体验反馈信息调整矫正周期数以及其余矫正周期对应的单次矫正量(单次矫正量的相关说明请参见图4的相关内容)。又或者，如果用户穿戴矫正件后感觉矫正件硬度过大，使用时疼痛感较为严重，可以基于该用户体验反馈信息调整其余矫正周期对应的足部矫正件的软硬程度(足部矫正件的软硬度的相关说明请参见图5的相关内容)。
在一些实施例中，可以是基于矫正结果信息先确定下一个矫正周期(如第二个矫正周期)的矫正件模型，在用户再穿戴下一个矫正周期的足底矫正件后， 再次获取矫正结果信息(如用户穿戴足部矫正件第二个矫正周期后的足弓信息)，并基于该矫正结果信息再确定其余一个或多个矫正周期的矫正件模型。在另一些实施例中，可以是基于矫正结果信息直接确定出其余多个矫正周期的矫正件模型。
在一些实施例中，矫正结果信息(包括足弓信息、足底形状信息、足底压力信息、步态信息、足底损伤位置信息、全足信息等)可以是基于用户穿戴足部矫正件一个矫正周期后的足弓尺寸的测量数据确定。也就是说，用户穿戴足部矫正件一个矫正周期后的足弓信息可以是对用户穿戴矫正件一个矫正周期后的足弓进行的测量后确定的。矫正结果信息中具体的相关信息的测量可以按照步骤210中的对应信息的测量方法进行测量。
在一些实施例中，矫正结果信息可以是基于用户穿戴足部矫正件一个矫正周期后的足弓尺寸的预测数据确定。也就是说，用户穿戴足部矫正件一个矫正周期后的足弓信息可以是在基于待矫正足部的足弓信息和上述一个周期的足部矫正件的相关尺寸(如足弓高度)等信息进行预测后确定的。在一些实施例中，预测数据可以基于待矫正足部的足弓信息和上述一个周期的足部矫正件的相关尺寸(如足弓高度)等信息，使用仿真软件进行确定。仅作为示例，可以基于待矫正足部的足弓信息(如足弓高度、足底压力数据等信息)和上述一个周期的足部矫正件的相关尺寸(如矫正鞋垫的足弓支撑部的高度、足弓支撑部的软硬度等)仿真预测出待矫正足部在使用足部矫正件(如矫正鞋垫)后的足底压力数据(如足底压力分布图)，通过该仿真预测的足底压力数据可以确定矫正结果信息，从而确定该一个矫正周期的矫正效果。
在一些实施例中，可以基于足底信息的足底形状信息、足底压力信息、步态信息、足底损伤位置信息等来调整和修改矫正件模型。在一些实施例中，可以基于足底形状信息、足底压力信息以及步态信息中的一种或多种来调节足部矫正件(如矫正鞋垫)的前掌部、足弓支撑部和/或的高度和轮廓。在一些实施例中，可以基于足底损伤位置信息来调节足部矫正件(如矫正鞋垫)上各个区域的 软硬程度(如硬度值)。例如，在对应足底损伤位置的区域，可以降低足部矫正件的硬度值。在一些实施例中，当足部矫正件为鞋子时，可以基于全足信息进行整鞋的尺寸设计，例如，可以基于足背高度设计鞋面高度。又例如，可以基于前掌宽度设计鞋底宽度。在一些实施例中，可以基于用户需求信息调节足部矫正件的单次矫正量、软硬程度(如硬度值)等。在一些实施例中，可以基于用户体重信息设计足部矫正件的软硬程度(硬度值)。例如，用户体重越重，可以设计足部矫正件的硬度越硬。
步骤240，基于矫正件模型，使用3D打印方式，打印出至少一个矫正周期对应的足部矫正件。
在一些实施例中，可以将矫正件模型的相关尺寸数据传输给3D打印设备或其配套的处理软件，以实现3D打印。在另一些实施例中，可以将矫正件模型的图形数据传输给3D打印设备或其配套的处理软件，以实现3D打印。
3D打印方式可以包括光固化成型打印方式、熔融沉积成型打印方式或激光烧结打印方式等。3D打印材料可以是粉末状金属或树脂等可粘合材料。在一些实施例中，3D打印设备可以是光固化3D打印机、熔融沉积3D打印机或激光烧结3D打印机等。与3D打印设备配套的处理软件可以包括Cura、EasyPrint3D、Slic3r、NetfabbBasic等。
优选地，3D打印方式选择为光固化成型打印方式。采用光固化成型打印方式具有打印速度快、打印精度高等优点。光固化成像的打印材料可以选择为树脂。树脂材料具有柔性和弹性，使得平面产品易于弯折，并且也能满足鞋类产品的弹性要求。
仅作为示例，对于光固化成型打印方式打印足部矫正件，3D打印机配套的处理软件(例如，Cura、EasyPrint3D、Slic3r、NetfabbBasic等)可以将具有一定厚度的矫正件模型的矫正件模型沿厚度方向划分成至少两层固化层，光固化打印机可以按顺序对至少两层固化层进行曝光，至少两层固化层的厚度可以相同或不同。例如，矫正件模型可以被划分为第一固化层、第二固化层和第三固化 层，光固化打印机可以按顺序对第一固化层、第二固化层和第三固化层依次进行曝光，其中，第一固化层成型在打印机的成型台上，第二固化层在成型完毕的第一固化层上成型，而第三固化层则在成型完毕的第二固化层上成型。第一固化层、第二固化层和第三固化层的厚度可以相同、部分相同或不同。例如，第一固化层的厚度可以是1.5mm，第二固化层的厚度可以是1.0mm，第三固化层的厚度可以是0.5mm。在一些实施例中，第一固化层、第二固化层和第三固化层的厚度可以为0.005mm-2.0mm。在一些实施例中，第一固化层、第二固化层和第三固化层的厚度可以0.01mm-0.2mm。
通过使用3D打印方式来打印出足部矫正件，可以提高足部矫正件的尺寸精度。另外，对于一个待矫正足部，即使需要制造多个矫正周期对应的足部矫正件，也无需通过准备多个模具，可以方便快捷地进行制造，且制造成本较低。在一些实施例中，足部矫正件可以包括弹性树脂材料。在一些实施例中，弹性树脂材料可以为聚氨酯丙烯酸酯、聚氨酯(甲基)丙烯酸酯、聚酯丙烯酸酯、环氧丙烯酸酯、硫代聚氨酯中的一个或多个的组合。在一些实施例中，弹性树脂材料也可以是具有一重或多重组分并能够进行多重固化的弹性树脂材料。在一些实施例中，弹性树脂材料也可以是具有双重组分并能够进行双重固化的弹性树脂材料。
在一些实施例中，足部矫正件的弹性模量为1MPa-50MPa。例如，足部矫正件的弹性模量可以为1Mpa、10Mpa、35Mpa、50Mpa等。其中，弹性模量指足部矫正件在单向应力作用下，应力除以该方向的应变的值。足部矫正件的弹性模量可以衡量足部矫正件产生弹性变形的难易程度，弹性模量越大，使足部矫正件发生一定弹性变形的应力也越大。在一些实施例中，可以基于用户体重设计足部矫正件的弹性模量，例如，用户的体重越大，则可以设计足部矫正件的弹性模量越大。
在一些实施例中，足部矫正件的拉伸强度为5MPa-50MPa。例如，足部矫正件的拉伸强度可以为5MPa、205MPa、45MPa、50MPa等。其中，拉伸强度指 足部矫正件在静拉伸条件下的最大承载能力。在一些实施例中，可以基于足部矫正件具体的应用场景来设计足部矫正件的拉伸强度。
在一些实施例中，足部矫正件的断裂伸长率为50％-60％。例如，足部矫正件的断裂伸长率为50％、52％、57％、60％等。其中，断裂伸长率指足部矫正件受外力作用至拉断时，拉伸前后的伸长长度与拉伸前长度的比值。在一些实施例中，可以基于足部矫正件具体的应用场景来设计足部矫正件的断裂伸长率。
在一些实施例中，基于矫正件模型，可以使用热压成型、注塑成型等方式制造足部矫正件。
图3是根据本申请一些实施例所示的确定矫正周期的方法的流程图。如图3所示，流程300可以包括以下步骤：
步骤310，基于用户信息，确定待矫正足部对应的正常足部的信息。
在一些实施例中，可以至少基于足长信息，确定待矫正足部对应的正常足部的信息。在另一些实施例中，也可以基于足底形状信息和/或全足信息等确定待矫正足部对应的正常足部的信息。在一些实施例中，待矫正足部对应的正常足部可以是与矫正足部的足长相同的正常足部。例如，可以至少基于足长信息，确定与矫正足部的鞋码相同的正常足部。又例如，可以至少基于足长信息，确定与矫正足部的足部长度尺寸相同的正常足部。在一些实施例中，正常足部的信息至少包括正常足部的足弓信息。在一些实施例中，正常足部的足弓信息可以包括正常足部的足弓尺寸信息、足弓形状信息等。在一些实施例中，正常足部的信息还可以包括正常足部的足长信息、足底形状信息、足底压力信息以及步态信息。正常足部的足长信息、足底形状信息、足底压力信息以及步态信息与待矫正足部的上述信息类似，具体可参见待矫正足部的足长信息、足底形状信息、足底压力信息以及步态信息等的相关说明。
步骤320，基于正常足部的信息和足弓信息，确定待矫正足部的矫正总量。
矫正总量可以理解为待矫正足部在所有矫正周期后需要实现的矫正值。在一些实施例中，当足弓信息包括待矫正足部的足弓的最高点的高度时，矫正总 量可以包括待矫正足部的足弓的正常最大高度与该待矫正足部的足弓的实际最大高度之间的差值。在另一些实施例中，当足弓信息包括待矫正足部的足弓的多个位置的足弓高度时，矫正总量包括待矫正足部的足弓的多个位置的高度矫正值。高度校正值可以理解为待矫正足部的足弓在某个位置的正常足弓高度与该待矫正足部的足弓的该位置的足弓高度之间的差值。
在一些实施例中，多个位置中每个位置的高度矫正值均为对应位置的足弓高度的0.1-0.5倍。通过将每个位置的高度矫正值均为对应位置的足弓高度的0.1-0.5倍，可以有效矫正扁平足问题，并减轻矫正期间用户的痛苦。在一些实施例中，多个位置中每个位置的高度矫正值均为对应位置的足弓高度的0.25倍。
步骤330，基于矫正总量，确定矫正周期数，以确定至少两个矫正周期。
在一些实施例中，在确定矫正总量后，可以根据矫正总量与预设阈值的比较结果来确定矫正周期数。上述预设阈值可以基于用户的足长信息来确定，例如，足长越长，说明用户的足部的足弓越高，则预设阈值可以越大。以扁平足的矫正为例，通过矫正总量与预设阈值的比较结果，可以反映用户的足弓塌陷问题的严重程度，从而基于此确定矫正周期数。当待矫正总量大于上述预设阈值，说明用户的足弓塌陷问题比较严重，则可以设置矫正周期数较多，如将矫正周期数大于四个。又例如，当矫正总量小于或等于上述预设阈值，说明用户的足弓塌陷问题比较轻微，则可以设置矫正周期数较少，如将矫正周期数设置为小于或等于四个。
图4是根据本申请一些实施例所示的确定矫正模型的方法的流程图。如图4所示，流程400包括下述步骤：
步骤410，基于矫正总量和矫正周期数，确定至少一个矫正周期对应的单次矫正量。
在一些实施例中，可以利用矫正总量除以矫正周期数而得到单次矫正量，通过这样的方式获取单次矫正量，任意两个矫正周期对应的单次矫正量相等。
在一些实施例中，确定至少一个矫正周期对应的单次矫正量可以是确定一个矫正周期对应的单次矫正量。例如，可以是确定第一个矫正周期的单次矫正 量。在一些实施例中，确定至少一个矫正周期对应的单次矫正量可以是确定多个矫正周期中每个矫正周期对应的单次矫正量。例如，可以是确定所有矫正周期的每个矫正周期对应的单次矫正量，也可以是确定所有矫正周期中的其中几个矫正周期的每个矫正周期对应的单次矫正量。
在一些实施例中，矫正周期数可以为至少三个。在步骤410中，可以基于矫正总量和矫正周期数，确定至少三个矫正周期中每个矫正周期的单次矫正量。在一些实施例中，在先的矫正周期的单次矫正量可以小于在后的矫正周期的单次矫正量。通过这样的设置，在逐步矫正用户的足部畸形的同时，可以尽可能减轻用户的痛苦。在另一些实施例中，为了提高矫正效率，在先的矫正周期的单次矫正量也可以大于在后的矫正周期的单次矫正量。
在一些实施例中，任意两个相邻的矫正周期对应的单次矫正量之间的差值相等。也就是说，各个矫正周期对应的单次矫正量可以排列成等差数列。通过这样的设置，可以实现循序渐进地对待矫正足部进行矫正，且大幅简化各个矫正周期对应的矫正件模型设计流程。
在另一些实施例中，任意两个相邻的矫正周期对应的单次矫正量之间的比值相等。也就是说，各个矫正周期对应的单次矫正量可以排列成等比数列。
步骤420，基于至少一个矫正周期对应的单次矫正量以及正常足部的信息，确定至少一个矫正周期对应的矫正件模型。
在一些实施例中，可以基于至少一个矫正周期对应的单次矫正量以及正常足部的信息确定矫正件模型的相关尺寸数据，再基于矫正件模型的相关尺寸数据来进行建模，从而确定至少一个矫正周期对应的矫正件模型。例如，当足底矫正件为矫正鞋垫时，矫正件模型的相关尺寸参数可以包括矫正鞋垫的总长度、前掌部的高度、足弓支撑部的高度和后跟部的高度中的一个或多个。
在一些实施例中，可以先确定矫正件的初始模型，再对初始模型进行调整，以确定矫正件模型。在一些实施例中，初始模型可以是存储在数据库中模型，可以基于足长信息和足弓信息匹配数据库中对应的初始模型。
在另一些实施例中，确定至少一个矫正周期对应的矫正件模型的流程420可以包括以下步骤：基于正常足部的信息，确定矫正件的初始模型；基于初始模型和至少一个矫正周期对应的单次矫正量，确定所述至少一个矫正周期对应的矫正件模型。其中，矫正件的初始模型可以是基于正常足部的信息建模后确定的。
在一些实施例中，可以根据单次矫正量修正初始模型的对应轮廓，以得到矫正件模型。在一些实施例中，可以基于单次矫正量对初始模型中的足弓支撑部进行调整，例如，调整初始模型中的应足弓支撑部的轮廓，以改变足弓支撑部的各个位置高度。
在一些实施例中，确定矫正件模型的操作可以是可以先确定足部矫正件的三维轮廓模型，再基于三维轮廓模型确定矫正件模型。在一些实施例中，在确定足部矫正件的三维轮廓模型之后，可以进一步设计和调节足部矫正件的软硬程度(如硬度值)，以最终确定矫正件模型。
在一些实施例中，足部矫正件的软硬程度的设计可以基于设计系统自动进行。在一些实施例中，可以基于用户信息，自动设计足部矫正件的软硬程度(如硬度值)。在一些实施例中，可以基于用户体重信息，自动设计足部矫正件的软硬程度(如硬度值)。
在一些实施例中，调节足部矫正件的软硬程度可以通过设置足部矫正件的材料来实现。例如，可以通过选择足部矫正件的材料或通过调节足部矫正件所包括的材料的配方，来调节足部矫正件的软硬程度。
在另一些实施例中，调节足部矫正件的软硬程度可以通过构建镂空网格并调节镂空网格的信息中的各项数据来实现，具体请参见图5的相关说明。
在一些实施例中，矫正件模型可以基于在矫正件的三维轮廓模型上构建镂空网格来确定。图5为本申请一些实施例所示的确定矫正件模型的流程的流程图，如图5所示，确定矫正件模型的流程可以包括以下步骤：
步骤510，基于用户信息，确定至少一个矫正周期对应的足部矫正件的三维轮廓模型。
确定三维轮廓模型的方法可以参照前述步骤230和流程400所述的确定矫正件模型的方法。在一些实施例中，至少一个矫正周期对应的足部矫正件的三维轮廓模型可以至少基于足弓信息以及足长信息来确定。在一些实施例中，三维轮廓模型可以基于足弓信息、足长信息、正常足部的信息、矫正总量、单次矫正量来进行建模，以生成三维轮廓模型。在一些实施例中，可以基于足底形状信息、足底压力信息、步态信息、足底损伤位置信息、全足信息、用户需求信息以及用户体重信息中的一个或多个来调整上述三维轮廓模型。在一些实施例中，也可以是基于正常足部的信息，确定足部矫正件的初始轮廓模型，再基于单次矫正量对初始轮廓模型进行调整，以获得足部矫正件的三维轮廓模型。
步骤520，在三维轮廓模型上构建镂空网格，以获得矫正件模型。
在一些实施例中，在三维轮廓模型上构建镂空网格，可以是先在三维轮廓模型的内部构建内腔，再在内腔中填充镂空网格。在另一些实施例中，在三维轮廓模型上构建镂空网格，可以是指使用镂空网格填充整个三维轮廓模型。在一些实施例中，在三维轮廓模型上构建镂空网格，可以是指使用镂空网格填充部分三维轮廓模型。
镂空网格包括多个相互连接的单元(每个网格可以理解为一个单元)，每个单元可以包括多个支柱，相邻的单元可以通过共享支柱而实现相互连接。在一些实施例中，镂空网格所包含的多个单元可以为棱柱体、椎体、四面体、六面体、八面体、十六面体、二十面体等多面体形状。另一些实施例中，镂空网格所包含的多个单元也可以为不规则的形状。在一些实施例中，不同单元的形状和尺寸可以相同。在另一些实施例中，不同单元的形状和尺寸可以不同。通过设置镂空网格，可以改变足部矫正件的物理性能(如回弹力、减震性和软硬程度等)，从而可以基于用户信息(如足底损伤位置信息、客户需求信息等)对足部矫正件的各个部位的物理性能进行调节。
在一些实施例中，三维轮廓模型上构建镂空网格的步骤可以包括以下子步骤：基于用户信息，确定镂空网格的信息；基于所述镂空网格的信息，在三维 轮廓模型上构建镂空网格。其中，镂空网格的信息可以包括镂空网格的形状数据、镂空网格的尺寸数据以及组成镂空网格的支柱的尺寸数据的一种或多种组合。
镂空网格的信息可以决定足部矫正件各位置的物理性能，例如，镂空网格的网格尺寸(如体积)越大，足部矫正件的越软。又例如，组成镂空网格的支柱的尺寸(如直径)越大，足部矫正件越硬。
在一些实施例中，基于用户信息，确定镂空网格的信息，可以是基于用户需求信息、足底损伤位置信息等来确定镂空网格的信息。例如，如果用户需求信息显示用户能够承受的矫正力度较弱，则可以通过设计镂空网格的信息，将足部矫正件设计得较软(增大镂空网格的尺寸和/或减小支柱的尺寸)。又例如，在确定足底损伤区域的具体位置后，可以将足部矫正件上足底损伤区域对应的位置设计得较软。
在一些实施例中，基于用户信息，确定镂空网格的信息，可以是基于用户体重信息来确定镂空网格的信息。在一些实施例中，可以预先设定用户的多个体重区间，以及每个区间所对应的足部矫正件的软硬程度(如硬度值)。基于用户的体重信息，可以确定足部矫正件的软硬程度，再基于该软硬程度来调节镂空网格的信息中的各项数据，以使得设置镂空网格后的足部矫正件可以达到该软硬程度。在一些实施例中，可以基于用户体重信息，自动地设计足部矫正件的镂空网格的信息，以调节足部矫正件的软硬程度(如硬度值)。
申请实施例可能带来的有益效果包括但不限于：(1)通过将矫正过程划分为多个矫正周期，并确定至少一个矫正周期的矫正件模型，基于该矫正件模型生成的足部矫正件可以阶段式地矫正足部，使得用户在每个矫正周期内的疼痛感都大幅减轻，提升用户体验，也使得用户更可能坚持地使用足部矫正件，保证矫正效果；(2)可以基于在前矫正周期的矫正结果信息来确定在后的一个或多个矫正周期的矫正件模型，以使得在后的矫正周期对应的足底矫正件能够根据用户的矫正情况进行调整，以保证较好的矫正效果；(3)通过在构建镂空网格而获得矫正件模型，可以便于调节足部矫正件的各项物理性能，以减小用户在穿 戴足部矫正件时的疼痛感受；(4)通过使用3D打印方式打印足部矫正件，避免采用多个模具来制造足部矫正件，可以简化足部矫正件的制作工艺，且降低制造成本。需要说明的是，不同的实施例可能产生的有益效果不同，在不同的实施例里，可能产生的有益效果可以是以上任意一种或几种组合，也可以是其他任何可能获得的有益效果。
本申请实施例还提供在一种足部矫正件，该足部矫正件由上述任一技术方案所述的制造方法制造。通过采用上述执照方法制造足部矫正件，使得足部矫正件能够达到矫正效果的同时，减轻用户的痛苦，且该足部矫正的制造过程简单方便，制造成本低，便于广泛地推广应用。
需要说明的是，不同实施例可能产生的有益效果不同，在不同的实施例里，可能产生的有益效果可以是以上任意一种或几种的组合，也可以是其他任何可能获得的有益效果。
上文已对基本概念做了描述，显然，对于本领域技术人员来说，上述详细披露仅仅作为示例，而并不构成对本申请的限定。虽然此处并没有明确说明，本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议，所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
同时，本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一个替代性实施例”并不一定是指同一实施例。此外，本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
此外，除非权利要求中明确说明，本申请所述处理元素和序列的顺序、数字字母的使用、或其他名称的使用，并非用于限定本申请流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例，但应当理 解的是，该类细节仅起到说明的目的，附加的权利要求并不仅限于披露的实施例，相反，权利要求旨在覆盖所有符合本申请实施例实质和范围的修正和等价组合。例如，虽然以上所描述的系统组件可以通过硬件设备实现，但是也可以只通过软件的解决方案得以实现，如在现有的服务器或移动设备上安装所描述的系统。
同理，应当注意的是，为了简化本申请披露的表述，从而帮助对一个或多个发明实施例的理解，前文对本申请实施例的描述中，有时会将多种特征归并至一个实施例、附图或对其的描述中。但是，这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字，应当理解的是，此类用于实施例描述的数字，在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明，“大约”、“近似”或“大体上”表明所述数字允许有±20％的变化。相应地，在一些实施例中，说明书和权利要求中使用的数值参数均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中用于确认其范围广度的数值域和参数为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
针对本申请引用的每个专利、专利申请、专利申请公开物和其他材料，如文章、书籍、说明书、出版物、文档等，特此将其全部内容并入本申请作为参考。与本申请内容不一致或产生冲突的申请历史文件除外，对本申请权利要求最广范围有限制的文件(当前或之后附加于本申请中的)也除外。需要说明的是，如果本申请附属材料中的描述、定义、和/或术语的使用与本申请所述内容有不一致或冲突的地方，以本申请的描述、定义和/或术语的使用为准。
最后，应当理解的是，本申请中所述实施例仅用以说明本申请实施例的原则。其他的变形也可能属于本申请的范围。因此，作为示例而非限制，本申请实施例的替代配置可视为与本申请的教导一致。相应地，本申请的实施例不仅限于 本申请明确介绍和描述的实施例。
