具体实施方式
以下由特定的具体实施例说明本申请的实施方式，熟悉此技术的人士可由本说明书所揭露的内容轻易地了解本申请的其他优点及功效。
在下述描述中，参考附图，附图描述了本申请的若干实施例。应当理解，还可使用其他实施例，并且可以在不背离本公开的精神和范围的情况下进行机械组成、结构、电气以及操作上的改变。下面的详细描述不应该被认为是限制性的，并且本申请的实施例的范围仅由公布的专利的权利要求书所限定。这里使用的术语仅是为了描述特定实施例，而并非旨在限制本申请。空间相关的术语，例如“上”、“下”、“左”、“右”、“下面”、“下方”、“下部”、“上方”、“上部”等，可在文中使用以便于说明图中所示的一个元件或特征与另一元件或特征的关系。
虽然在一些实例中术语第一、第二等在本文中用来描述各种元件或参数，但是这些元件或参数不应当被这些术语限制。这些术语仅用来将一个元件或参数与另一个元件或参数进行区分。例如，第一足压干预区域可以被称作第二足压干预区域，并且类似地，第二足压干预区域可以被称作第一足压干预区域，而不脱离各种所描述的实施例的范围。第一足压干预区域和第二足压干预区域均是在描述一个足压干预区域，但是除非上下文以其他方式明确指出，否则它们不是同一个足压干预区域。
再者，如同在本文中所使用的，单数形式“一”、“一个”和“该”旨在也包括复数形式，除非上下文中有相反的指示。应当进一步理解，术语“包含”、“包括”表明存在所述的特征、步骤、操作、元件、组件、项目、种类、和/或组，但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。此处使用的术语“或”和“和/或”被解释为包括性的，或意味着任一个或任何组合。因此，“A、B或C”或者“A、B和/或C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A、B和C”。仅当元件、功能、步骤或操作的组合在某些方式下内在地互相排斥时，才会出现该定义的例外。
在现有的鞋类制品制造中，通常基于用户的需求例如对舒适度的考虑，将鞋底的高度适度调整，例如将鞋底设置为鞋底后跟部略高出鞋底的前掌部，以适应于人在步行中通常后跟先着地的行走发力方式。又或，在某些场景中，为实现鞋类对足部的保护，在鞋底制造中选择采用弹性佳的材料如EVA实现鞋底减震，基于材料的弹性变形，运动中足底的接触面积可增大即实现分压等。
但人体的足底压力分布往往与个人的生理状态以及步态习惯等有关，同时，不同个体在静止状态与运动态下的适宜的足底压力分布不同，统一制作的鞋类制品难以满足用户个体的特定需求。针对于一定数量的同类目标用户群体，其适宜的足压调整方式也需要数据分析作为科学基础，例如根据此类用户群体的特定信息：足底轮廓、体重、医疗数据等确定适宜用户的预期的压力状态，使得压力分布有利于人体足形矫正与穿着的舒适度。
请参阅图1，显示为本申请在第一方面提供的用于鞋类制品的鞋中底在一实施例中的结构示意图，包括：对应目标用户脚后跟的后跟部13，对应目标用户前脚掌的脚掌部11，连接所述后跟部与脚掌部的对应于目标用户的腰窝部12，所述后跟部13即对应于目标用户后脚跟的踩踏部位，所述脚掌部11即对应于目标用户脚掌的踩踏部位。
其中，所述目标用户可以为所述类鞋制品的使用者，在本申请提供的实施例中，基于所述目标用户的特定信息形成用于鞋中底的制造信息例如材料信息、鞋中底结构信息、制作工艺信息等。
所述目标用户的特定信息是由对目标用户个人身体状态与需求进行采集，并对采集信息分析获得的，用于指示鞋中底结构设计的个性化信息。又或，对于某一类型的目标用户群体，所述目标用户的特定信息是由针对该类群体的大数据获取的，在此，对大数据的特征进行分析，由数据所表现的普遍规律确定该类目标用户群体适用的鞋中底制造信息，例如：对于患有糖尿病的目标用户，通常容易患有糖尿病足即由糖尿病引发的足底溃烂、胼胝；基于医学上的对应的糖尿病足患者的足底分析及统计，对于为糖尿病患者的目标用户群体，对于足底未发生胼胝等明显病变的糖尿病患者，可基于医学统计分析预先确定足底的保护区域。
所述脚掌部和所述后跟部对应的区域中设有至少一个第一足压干预区域，所述第一足压干预区域内的拓扑结构或晶格结构的受力强度小于第一足压干预区域之外的拓扑结构或晶格结构的受力强度。在某些实施方式中，所述第一足压干预区域设置在所述脚掌部或后跟部，又或同时设置在脚掌部与后跟部中。如图1所示，所述鞋中底的脚掌部11设置有一第一足压干预区域111及另一第一足压干预区域112，后跟部设置有第一足压干预区域131。
所述第一足压干预区域可根据所述目标用户的特定需求确定，在本申请提供的各实施例中，所述第一足压干预例如为足部的指定保护部位、足部溃疡部位等需要将压力进行分散转移的区域，又或别的基于足底的舒适度或保护等需求进行压力调整分散的区域，其具体位置可进一步基于目标用户的脚型轮廓与特定需求确定。在一些示例中，所述第一足压干预区域内的晶格结构与第一足压干预区域之外的晶格结构基本单元的形式不同，以满足在人体踩压承重时，鞋中底的压力以预设效果自然分配。
在某些实施方式中，位于所述第一足压干预区域之外的拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构或晶格结构呈渐变过渡，以使所述至少一个第一足压干预区域内的拓扑结构或晶格结构的受力强度小于所述至少一个第一足压干预区域之外的拓扑结构或晶格结构的受力强度。
在某些实施例中，所述渐变过渡包括晶格体结构渐变例如晶格结构基本单元大小渐变、基本单元疏密渐变、晶格壁面厚度渐变、晶格杆径长度渐变、晶格杆径粗细渐变、晶格结构基本单元的几何结构(如几何结构类型)的连续渐变，以及包括由后处理工艺或打印工艺等形成晶格结构的性能渐变如成型后的晶格结构密度渐变、晶格结构材料渐变；又或，所述渐变过渡为拓扑结构的结构体渐变例如拓扑结构中连接杆体的杆径粗渐变、拓扑结构壁面厚度渐变、拓扑结构的杆径间连接方式渐变形成的体积渐变或制造工艺、后处理工艺形成的拓扑结构材料密度渐变等。
在一种示例中，预先确定所述至少一个第一足压干预区域，在此，例如确定至少一个第一足压干预区域在鞋中底的位置和轮廓，对位于所述第一足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构或晶格结构确定交界区域，将交界区域内的拓扑结构设置为渐变过渡，或将晶格结构基本单元设置为呈过渡渐变的形式。在此，所述交界区域与第一足压干预区域可以相交或毗邻，也即，呈渐变过渡的拓扑结构或晶格结构基本单元可以延伸至第一足压干预区域内，又或延伸至所确定的第一足压干预区域边界(或轮廓)处。
在一些具体示例中，所述交界区域内的晶格结构设计为晶格结构的基本单元大小渐变的形式；又或，在所述交界区域的晶格结构的基本单元几何结构类型渐变，例如从第一足压干预区域外的晶格结构基本单元为锥形体，顺应延伸方向逐渐形变，至所述至少一个第一足压干预区域内形成为球状体的基本单元；再如，对打印工艺设进行置，在所述交界区域的晶格结构从第一足压干预区域之外朝向第一足压干预区域延伸，对应的晶格结构基本单元呈现出 材料密度渐变的形式。
在另一些具体示例中，所述交界区域内的拓扑结构基于连接方式改变使得交界区域的受力强度呈渐变过渡。应当理解，通常的拓扑结构不具有周期性，在此，拓扑结构的连接形式可任意设定，在一些实现方式中，可将交界区域的拓扑结构划分为不同子区域，确定每一子区域内的拓扑结构体积密度以表征对应子区域内的拓扑结构强度。在此，为实现所述位于所述第一足压干预区域之外的拓扑结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构呈渐变过渡，可顺应延伸方向令拓扑结构中子区域内的连接杆节点处的公用连接数或区域内所有节点的平均公用连接数减小，又或，顺应延伸方向令拓扑结构中子区域中拓扑结构的杆径粗细逐渐减小。
在此，基于所述第一足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构或晶格结构的渐变过渡，所述鞋中底在被穿着的状态下，所承担的压力在不同区域间呈连续变化，例如，在确定的所述至少一个第一足压干预区域在鞋中底的位置及轮廓处，该轮廓内与轮廓外的足底压力是连续变化的。例如基于鞋中底轮廓区域绘制压力云图，每一单位区域对应一平均压力数值，在此获得的压力云图中相邻单位区域内的压力变化值在预设值以内，即可认为足底压力为连续变化的。在此，基于对拓扑结构或晶格结构的渐变过渡设置，例如材料密度渐变，又或结构渐变如晶格体基本单元杆径渐变或不同区域的拓扑结构杆径渐变，令足压压力调整为整体连续的状态。在此连续变化的压力状态下，鞋中底具有较好的缓冲能力，不同区域间可有效实现压力传递与分担；同时，减缓人体穿着态下局部压强过大的不适触感。
所述单位区域以及压力变化的预设值可人为设定，又或，基于目标用户的医疗干预数据进行确定，例如确定适宜于足底养护的压力峰值，在确定第一足压干预区域之后，令位于所述第一足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构或晶格结构呈渐变过渡以减小第一足压干预区域之外的压力峰值，又或，确定鞋中底不同区域的压力变化值的压力突变的阈值，在此，所述阈值可基于医学数据或鞋制品性能设定，如当足压存在过大的突变时容易产生足底刺痛，在此，可基于医学分析确定足压突变的阈值以减轻或消除不适感，又如当鞋中底不同区域承受的压力值存在过大突变，则缓冲功能可能被削弱，在此可减小交界区域的压力突变以实现渐变过渡；再者，还可通过鞋类制品的制造工艺(标准)进行确定，例如，确定适合鞋底缓冲的压力变化状态，以增强鞋中底的缓冲功能或鞋中底的耐冲击、磨损等性能。
所述晶格结构即构成所述鞋中底的单元结构形式，在宏观上晶格结构的基本单元之间的形状与位置关系类似于化学分子中的晶格结构。
在某些实施方式中，组成鞋中底的基本单元结构为一定形状的空间连接杆，各连接杆之间的位置关系可呈现为晶体中晶胞单元的各个原子之间连接键的位置关系的形式。当然，所述鞋中底的晶格结构的基本单元形式不以实际存在的晶胞的连接形式为限制，而在于采用晶胞原子间具有空间方位的连接键的结构形式。由所述晶格结构组成的鞋中底为镂空结构。所述晶格结构采用了化学分子间的晶体连接共用键的形式，对应于不同的连接形式，该晶格结构的性能不同。例如，对应于每一晶格基本单元上的节点，当选用不同的连接方式则可能对应不同的价数，所述价数可用于指示晶格结构的基本单元之间的互相连接的程度，价数越低，则对应的基本单元之间共用的连接杆数量少。
在某些实施方式中，所述晶格结构设置为由面状的镂空结构组成，所述晶格结构的基本单元为具有一定壁厚的空心多面体如四面体、六面体等，晶格结构的基本单元通过共用面的形式连接，以形成预设的鞋中底轮廓。
在某些实施方式中，对于采用连接杆形成基本单元的晶格结构或采用面状体为基本单元的晶格结构，所述晶格结构中的每一个基本单元结构为相同或近似相同的几何结构，也即，所述晶格结构中的基本单元之间具有一定周期性，所述晶格结构亦在不同的位置呈拉伸、扭曲或压缩变形结构。所述晶格结构在采用具有空间方位的连接键或共用面的基础上，可划分为多个连接形式相似的基本单元，整体结构呈现为由基本几何单元堆积形成。所述晶格结构组成的鞋中底的3D结构在不同部位的基本单元结构呈一定的变形处理，例如，在构成鞋中底外部轮廓处的基本单元，顺应于轮廓设计，在不同位置呈现出不同的变形处理如拉伸、扭曲或压缩等变形结构，所述变形处理为无外部压力状态下对基本单元结构的连接形式的调整以顺应鞋中底形态设计。所述对基本单元的变形处理可以是在晶格基本单元的长度、宽度、高度或其中两者以上方向的伸缩变换或扭转处理，基于对鞋中底晶格结构的整体轮廓设计与不同方向的强度设计决定。
在某些实施方式中，所述几何结构包括多面体，例如包括锥形体、菱形体、星状体中的一种或多种的组合，以及球状体等。其中，对于以连接杆组成基本单元的晶格结构，所述鞋中底的实体结构对应基本几何单元体的棱边；对于基本单元为中空多面体的晶格结构，所述几何结构为面状体，所述鞋中底的实体结构对应于基本几何单元的壁面，其中，所述壁面包括平面、弧面或曲面，所述基本几何单元例如为包括锥形体、菱形体、星状体中的一种或多 种的组合，以及球状体等。所述鞋中底可采用一种简单几何结构作为晶格结构的基本单元，也可选用多种几何结构的组合形成晶格结构的基本单元，亦可在不同的位置区域设置为不同的基本几何单元结构，例如在腰窝部采用菱形体结构为基本单元，在后跟部或脚掌部以多面体为基本单元。
在某些实施方式中，所述晶格结构设置为采用面状体的晶格结构，所述面状体比如极小曲面结构，所述极小曲面结构的晶格结构能够为运动鞋提供减震缓冲性能，多个曲面填充和/或拼接和/或阵列构成的结构，拼接成单元主体，由多个单元主体填充和/或拼接和/或阵列构成的极小曲面结构形成良好的交错成坚固支柱，这些支柱能使鞋中底支撑性更强，在一种实施例中，所述极小曲面结构的晶格结构例如为专利公开号CN110652069A中描述的极小曲面结构。
所述拓扑结构为基于共用节点连接不同杆体以形成的镂空连接体，其中，所述鞋中底拓扑结构的实体即为其中的杆体。所述拓扑结构的连接方式可基于人为需要设置，例如，拓扑结构中每一杆体的端点与至少一杆体共用端点，每一端点对应具有一共用连接数，在此，所述共用连接数可预设为不同数值例如2、3、4、5、6等，所述共用连接数位节点处连接的杆体总数；再者，所述拓扑结构中杆体的连接方向可以任意设置，在某些示例中，还可对所述拓扑结构进行优化，以使得所述拓扑结构整体有序性增加例如令拓扑结构中每一节点处的共用连接数相同。
在某些示例中，所述拓扑结构可根据需要设计为仿生结构例如树型的枝干延伸的结构，例如将拓扑结构中的杆径连接形式设置为仿照枝干延伸时杆径粗细、连接节点数顺应树梢方向改变的形式；又如，将拓扑结构中的杆径连接形式设置为微观的细胞形态；再如，将拓扑结构中的杆径连接形式设置为叶片中脉络形态，在一示例中，拓扑结构可显示为由第一基本单元(类似于叶片中主脉和侧脉)和第二基本单元(类似于叶片中细脉)组成，其中，第一基本单元的杆径粗细与杆径长度均大于第二基本单元，由第二基本单元在第一基本单元中填充以形成鞋中底拓扑结构，所述第一基本单元即可用于确保鞋中底的强度，其中填充的第二基本单元即可用于增加鞋中底的弹性形变能力；在此，所述第一基本单元、第二基本单元中基本单元具体形式均可任意设置，也即不同基本单元的形式不以周期性为限制。
在某些示例中，所述拓扑结构也可为面状体，在此，所述拓扑结构的面状体中包括有多个孔隙，例如，拓扑结构中单个面状体的壁面为实体，所述壁面包括平面、弧面或曲面。在此，所述拓扑结构中单个面状体的形式包括椎体、多面体、球状体等，且鞋中底的拓扑结构 中每一单个面状体的形式均可任意设定，在某些示例中，也可对拓扑结构进行优化，以增加面状体的周期性。
同时，在承受外部压力的状态下，所述拓扑结构或晶格结构具有对应不同受力方式的抗拉伸、抗扭矩、抗剪切的刚度或弹性形变能力，即具有一定的强度。例如，所述第一足压干预区域内的拓扑结构或晶格结构的强度小于第一足压干预区域之外的拓扑结构或晶格结构的强度，以实现承重时鞋中底可将第一足压干预区域的压力分散转移至其他区域的效果。在具体实施方式上，所述拓扑结构或晶格结构的强度与所承受的压力、剪力等的对应关系可基于对拓扑结构或晶格结构的强度性能测试获得，所述测试可为对拓扑结构实体或晶格结构实体的检测，又或采用应力应变关系结合材料本身的性能进行模拟计算，或将模拟计算与设计检测结果对照以将晶体结构强度与晶格结构关联或将拓扑结构形式与拓扑结构的强度关联。
所述拓扑结构、晶格结构的强度可由拉伸强度、压缩强度、剪切强度、弯曲刚度、扭转刚度及韧性如弹性形变能力等强度性能指标表征，在所述鞋中底中，所述晶格结构强度主要用于确保在穿着状态(包括自然站立、步行运动、跑步运动等穿着状态)下鞋中底处于弹性形变状态且对应的形变量处于预设范围之内。
在某些实施方式中，所述晶格结构的受力强度是通过每一晶格结构的体积密度、晶格体结构、打印材料、打印工艺、以及后处理工艺中的至少一种确定的；或，所述拓扑结构的受力强度是通过确定拓扑结构的体积密度、打印材料、打印工艺、以及后处理工艺中的至少一种确定的。
在一些实例中，所述晶格结构的体积密度与杆径粗细、晶格壁面厚度、晶格大小、成型后晶格杆体的密度相关；所述拓扑结构的体积密度与拓扑结构的杆径粗细、成型后拓扑结构杆体密度相关。
所述晶格结构的实体结构为连接杆或壁面形式，所述晶格结构的体积密度则与基本单元的连接杆的长度、直径、连接疏密等相关，当所述鞋中底由所采用密度均匀的材料填充，则其体积密度可表征在单位体积内的材料用量。一般来说，当晶格结构的基本单元的连接形式确定时，晶格结构的受力强度与其体积密度正相关，当所述晶格结构的基本单元越小即连接杆长度越小，对应的体积密度越大，则鞋中底的晶格结构具有更大的强度；又或，当连接杆的杆径直径越大，对应的体积密度越大，则鞋中底的晶格结构具有更大的强度；再如，对应于不同连接方式的晶格结构单元，对与所采用基本单元中连接杆节点杆节点处的价数不同的两种晶格结构，一般来说所分别对应的体积密度以及结构强度不同。
在某些实施方式中，对于以共用面连接的晶格结构，所述晶格结构的体积密度与基本单元壁面的厚度也即壁厚、基本单元大小以及基本单元的几何结构有关。一般的，所述基本单元的壁厚与体积密度正相关，例如，当增加基本单元的壁厚，晶格结构的体积密度增加，同时晶格结构的强度增加；又如，当基本单元壁厚与几何结构确定，当基本单元大小等比例缩小但壁厚不变，获得体积密度增加的晶格结构，同时具有更大的强度。对于基本单元为不同几何结构的鞋中底，也可能具有不同的结构强度，如基本单元分别为四面体与球状体的两种晶格结构，鞋中底的拉伸强度、压缩强度、剪切强度等强度性能不同。
在某些实施方式中，所述晶格结构的受力强度还与连接杆的连接方式如基本晶胞结构中连接杆的连接方向相关。例如，当基本晶胞单元的连接形式分别为锥形几何体为基本几何单元与正六面体为基本几何单元的两种连接方式，对应的晶格结构强度不同。由于鞋中底的晶格结构采用杆件连接形式，当杆件方向不同，在受压状态下对应的杆件间力的传递方向不同，晶格结构抵抗变形的能力也不同。
在某些实施方式中，所述晶格结构在鞋中底的不同区域选择为不同的晶胞结构或基本单元几何结构与体积密度，但鞋中底晶格结构的体积密度的变化在鞋中底区域内是连续变化的，以实现所述鞋中底的为足部提供充足的缓冲力。
将所述拓扑结构的体积密度定义由单位区域内拓扑结构实体即杆体的体积确定，或由材料密度及杆体体积确定，在一示例中，通过设置每一单位区域内的拓扑结构的杆体杆径粗细确定拓扑结构体积密度分布，以实现鞋中底拓扑结构的不同区域依预设压力分布规律承担压力，例如，当所述拓扑结构中的杆体的材料密度均匀，将单位区域内的拓扑结构中的杆体杆径增加，使得该单位区域内的杆体体积增加，相应的该单位区域内的拓扑结构体积密度增加。
当所述鞋中底为采用3D打印工艺制造，通常成型后的鞋中底强度性能与打印材料相关，在此，可基于对打印材料的设置形成结构强度不同的实体，在某些示例中，确定所述晶格结构或拓扑结构的受力强度时以预先确定打印材料为基础。
在某些实施方式中，所述拓扑结构或晶格结构的受力强度与连接杆或壁面的材料密度相关。在此，所述材料密度可基于打印材料或打印工艺确定。例如，当所述拓扑结构或晶格结构采用3D打印的烧结方式制作，在进行烧结固化的过程中，当辐射的能量密度不同，烧结件对应的固化部分密度不同。如对于陶瓷粉末通常随激光能量密度增加，烧结件的强度呈先增大后减少的趋势，即不同材料在烧结中对应有获得最佳密度的能量值；在具体打印中根据选用的材料特性，将辐射的能量密度设置为最佳密度对应能量值，则烧结形成的晶格结构具有 更大的强度；又如，当烧结材料的粉末颗粒度不同，则烧结性能可能不同，对于特定的材料，当设置适宜的粉末态如粉末大小与粉末几何形态，进行烧结获得微观组织致密的烧结件，则连接杆的材料密度更大，具有更大的强度。
在某些实施方式中，所述拓扑结构或晶格结构的受力强度还与打印的后处理工艺有关，例如通过3D打印获得所述鞋中底后，对一定区域如第一足压干预区域外的拓扑结构或晶格基本单元进行结构加强处理或化学处理以强化该区域对应的拓扑结构强度或晶格结构强度。
在某些实施方式中，所述第一足压干预区域之外晶格结构朝向所述至少一个第一足压干预区域之内延伸的晶格结构呈渐变过渡是通过确定晶格结构的体积密度、晶格体结构、打印材料、打印工艺、以及后处理工艺中的至少一种实现的；或，所述第一足压干预区域之外拓扑结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构呈渐变过渡是通过确定拓扑结构的体积密度、打印材料、打印工艺、以及后处理工艺中的至少一种实现的。
在一种具体实施方式中，请参阅图2a、图2b，其中，图2a显示为本申请的鞋中底在一实施例中的部分区域的晶格结构示意图，图2b显示为鞋中底部分区域的晶格结构的侧视图。如图2a、图2b所示，在确定了鞋中底的至少一个第一足压干预区域后，位于第一足压干预区域外的晶格结构朝向第一足压干预区域延伸的晶格结构基本单元的杆径逐渐减小(呈如图2a、图2b中的顺应箭头的X方向)，对应的，晶格结构的体积密度从第一足压干预区域之外至第一足压干预区域内逐渐减小，由此，位于第一足压干预区域之外的晶格结构所具有的强度朝向第一足压干预区域延的晶格结构所具有的强度呈逐渐减小。在此，由于位于第一足压干预区域外的晶格结构朝向第一足压干预区域延伸的晶格结构基本单元的杆径逐渐减小，使晶格结构整体无形状突变。
请参阅图2c、图2d，分别显示为基本单元采用另一几何结构的晶格结构立体示意图与平面示意图，如图所示，所述鞋中底中基本单元为类六边形的孔状体，晶格结构实体对应于作为六边形边长的连接杆，位于第一足压干预区域外的晶格结构朝向第一足压干预区域延伸的晶格结构的体积密度逐渐降低；在一实现方式中，例如图示实施例中，顺应朝向第一足压干预区域延伸的方向(呈如图2c、图2d中顺应箭头的X方向)，晶格结构基本单元的杆径逐渐减小。令第一足压干预区域之外晶格结构朝向所述至少一个第一足压干预区域之内延伸的晶格结构呈渐变过渡也可通过设置基本单元大小实现，例如，第一足压干预区域之外晶格结构朝向第一足压干预区域的晶格结构基本单元的杆径长度逐渐增加，对应的晶格结构基本单元体积密度逐渐降低，受力强度逐渐减小。
在另一些实现方式中，当所述晶格结构基本单元为面状体形式，可通过改变晶格结构基本单元的壁面厚度实现渐变过渡，其包括但不限于将位于第一足压干预区域外的晶格结构朝向第一足压干预区域延伸的晶格结构基本单元的壁面厚度设置为顺应延伸方向逐渐减小，例如，为连续的线性减小。
在此，所述位于第一足压干预区域外的晶格结构朝向第一足压干预区域延伸的晶格结构的渐变过渡可基于采用的晶格结构具体类型确定，例如，当所述晶格结构为面状体，其中不同基本单元之间存在孔隙，可通过顺应朝向第一足压干预区域的方向，逐渐增加孔隙大小，对应的晶格结构基本单元的体积密度逐渐降低，也可获得实现所述晶格结构的渐变过渡。晶格结构可选形式与实现渐变过渡的方式不以图示实施例为限制。
在另一种具体实施方式中，所述渐变过渡也可通过晶格体结构的渐变实现，例如晶格结构基本单元大小渐变、基本单元疏密渐变、晶格壁面厚度渐变、晶格杆径长度渐变、晶格杆径粗细渐变、晶格结构基本单元的几何结构(如几何结构类型)的连续渐变等。
请参阅图2e，显示为一实施例中所述鞋中底的拓扑结构中的部分区域的结构示意图。如图2e视图显示的拓扑结构中具有一第一足压干预区域，其中，拓扑结构中第一足压干预区域内的杆体杆径小于第一足压干预区域之外的杆体杆径，在此，所述杆径变化为渐变形式；如图所示，在朝向所述第一足压干预区域的方向上，拓扑结构中的杆体杆径逐渐减小，以使得从第一足压干预区域之外的拓扑结构朝向第一足压干预区域延伸的拓扑结构的体积密度逐渐降低。
在又一些具体实施方式中，所述渐变过渡也可通过打印材料的变化实现，例如通过使用不同硬度的打印材料，使不同硬度的打印材料所打印出的拓扑结构或晶格结构具有不同的强度，从而借由打印材料硬度的渐变而实现位于第一足压干预区域外的拓扑结构或晶格结构朝向第一足压干预区域延伸的拓扑结构或晶格结构的渐变过渡。
在再一种具体实施方式中，所述渐变过渡也可通过打印工艺实现，例如所述鞋中底采用3D打印工艺制成，在辐射成型过程中令第一足压干预区域之外的拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构或晶格结构对应接收的辐射能量密度逐渐变化，例如顺应延伸方向能量密度逐渐降低，使得固化成型的拓扑结构或晶格结构强度逐渐降低。
在还有一种具体实施方式中，所述渐变过渡也可通过后处理工艺实现，例如通过去除晶格结构的部分杆体以改变晶格结构的强度，又如通过去除拓扑结构中部分杆体减小节点连接 数以改变拓扑结构的强度；又如在基于3D打印工艺制程的鞋中底中，在打印完的鞋中底通过3D打印的后固化步骤，对第一足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构或晶格结构采用不同强度的光源照射等。
在本申请的一实施方式中，所述第一足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构或晶格结构呈渐变过渡也即所述交界区域对应的拓扑结构或晶格结构强度或对应的压力分布的渐变过渡，基于本申请提供的确定鞋中底拓扑结构或晶格结构的受力强度的方法，通过对鞋中底制造(包括后处理工艺)中受力强度的至少一种影响因素进行设置，即可实现第一足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内延伸的拓扑结构或晶格结构呈渐变过渡，由此增加了用户使用时的舒适度。
请参阅图3a，显示为本申请的鞋中底在一实施例中的结构示意图，如图3a所示，所述鞋中底的晶格结构在不同区域采用了不同的连接形式或不同的体积密度。在所述鞋中底的前掌与后跟区域中分别设置有第一足压干预区域，所述第一足压干预区域即对应于图3a所示实施例中晶格疏密度降低的区域，如脚掌部11的第一足压干预区域111、第一足压干预区域112后跟部13的第一足压干预区域131，其对应的晶格结构的体积密度降低。基于对第一足压干预区域的晶格结构强度削弱的设计；在某些实例中，所述鞋中底也可采用拓扑结构，并在其中设置多个第一足压干预区域，通过确定决定拓扑结构结构强度的表变量如打印工艺、体积密度等，在鞋中底设计或制作中削弱第一足压干预区域对应的拓扑结构的强度，在此，鞋中底在被踩踏的状态下，所承受的压力自然分散至第一足压干预区域之外的对应有较大结构强度的区域以实现对人体的支持力与压力的平衡。
在某些实施方式中，所述第一足压干预区域的晶格结构的强度与计算获得的期望足压数据相关，其中，所述期望足压数据小于对应所述至少一个第一足压干预区域的实测足压数据。
请参阅图3b，显示为本申请的鞋中底在一实施例中的结构示意图。在某些实施方式中，所述鞋中底中设有至少一个第二足压干预区域，在此，所述鞋中底可采用晶格结构(如图3b所示)或拓扑结构(未予以图示)，鞋中底中设置有至少一个第二足压干预区域，如图3b所示的第二足压干预区域113，所述第二足压干预区域113位于鞋中底的后跟部、脚掌部、或腰窝部；其中，位于所述第二足压干预区域之外的拓扑结构或晶格结构朝向所述至少一个第二足压干预区域之内延伸的拓扑结构或晶格结构呈渐变过渡，以使所述至少一个第二足压干预区域113内的拓扑结构或晶格结构的受力强度大于所述至少一个第二足压干预区域113之外 的拓扑结构或晶格结构的受力强度。
在此，所述受力强度是通过每一晶格结构的体积密度、晶格体结构、打印材料、打印工艺、以及后处理工艺中的至少一种确定的；又或，通过拓扑结构的体积密度、打印材料、打印工艺、以及后处理工艺中的至少一种确定鞋中底拓扑结构不同区域的结构强度。
所述第二足压干预区域对应的拓扑结构或晶格结构的受力强度大于第二足压干预区域外的拓扑结构或晶格结构体积密度，以对应获得强度更大的实体结构。在某些实施方式中，所述鞋中底第一足压干预区域采用弱化的强度设计，为实现对足底压力分配的调整，设置结构强度增加的所述第二足压干预区域以平衡压力分配，基于所述第二足压干预区域采用的强度增加的结构设计，所述鞋中底在穿着中的被踩踏状态下可将压力自然分配至第二足压干预区域。
在此，位于所述第二足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第二足压干预区域之内的拓扑结构或晶格结构为过渡渐变，在某些示例中，是通过设置拓扑结构或晶格结构受力强度的决定因素如晶格结构的体积密度、晶格体结构、拓扑结构体积密度、打印材料、打印工艺、以及后处理工艺中至少一种实现的。
请参阅图4a、图4b，显示为本申请的鞋中底的晶格结构在一实施例中的示意图。如图所示，所述晶格结构的基本单元采用杆径连接形式，其中，基本单元顺应图示箭头方向的X方向杆径逐渐增加即变粗，在此，X方向对应于鞋中底的第二足压干预区域之外向第二足压干预区域延伸的方向，基于此对晶格结构基本单元的设置，位于所述第二足压干预区域之外晶格结构朝向所述至少一个第二足压干预区域之内的晶格结构的受力强度逐渐增加，对应承担的足底压力逐渐增大。
请参阅图4c，显示为一实施例中所述鞋中底的拓扑结构部分区域的结构示意图，如图所示，顺应图示X方向，拓扑结构中连接杆体的杆径逐渐增加，在此，X方向对应于鞋中底的第二足压干预区域之外向第二足压干预区域延伸的方向，基于此设置，位于所述第二足压干预区域之外拓扑结构朝向所述至少一个第二足压干预区域之内的拓扑结构的受力强度逐渐增加，对应承担的足底压力逐渐增大。
在某些示例中，顺应第二足压干预区域之外向第二足压干预区域延伸的方向，所述拓扑结构可设置为单位区域的节点连接数逐渐增加(未予以图示)，以形成朝向所述第二足压干预区域的体积密度渐变式增大，对于拓扑结构的受力强度逐渐增加。
在此，应当理解，所述第二足压干预区域与第一足压干预区域对应的拓扑结构或晶格结 构受力强度影响因素类似，对不同区域晶格结构基本单元的设置或对拓扑结构在不同区域的设计，在于实现鞋中底在被穿着时压力分布为预期的分布状态。令位于所述第二足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第二足压干预区域之内的拓扑结构或晶格结构为过渡渐变的方式，也可通过打印工艺、后处理工艺、打印材料等实现，相比令位于所述第一足压干预区域之外拓扑结构或晶格结构朝向所述至少一个第一足压干预区域之内的拓扑结构或晶格结构为过渡渐变的方式，其具体实施方式类似，在此不再赘述；相应的，从第一足压干预区域之外延伸至第一足压干预区域，和从第二足压干预区域之外延伸至第二足压干预区域，由于过渡渐变分别为逐渐减小和逐渐增加，顺应延伸方向对晶格体基本单元或拓扑结构的调整通常相反。特别的，所述第一足压干预区域与第二足压干预区域均可基于目标用户的期望足压数据确定在鞋中底中分布的区域。
在某些实施方式中，所述第二足压干预区域的拓扑结构或晶格结构的强度与计算获得的期望足压数据相关，其中，所述期望足压数据大于对应所述至少一个第二足压干预区域的实测足压数据。
所述期望足压数据即预期的本申请的鞋中底在被穿着状态下对应的人体足压数据，即经过所述鞋中底调整后的足压数据。
在对鞋中底的实际制作中，所述鞋中底的整体结构均基于目标用户的身体因素如脚形轮廓数据、步态数据、形体数据、体重数据、实测足压数据以及医疗干预数据等数据进行设计，可认为所述鞋中底整体区域的压力均由期望足压数据确定。
在某些实施方式中，基于对目标用户的足底保护的需要，由所述期望足压数据与实测足压数据确定需要进足底减压的区域也即所述第一足压干预区域，基于第一足压干预区域的范围以及该区域对应的压力范围，对拓扑结构或晶格结构的强度进行调整以确定将其余压力分散至第一足压干预区域之外。
在某些实施方式中，由所述期望足压数据确定对目标用户的足压调整方式，基于压力分配的需要，确定可用于进行压力承担的区域也即所述第二足压干预区域，将第二足压干预区域对应的拓扑结构或晶格结构设计强度增加，以实现鞋中底在穿着状态下第二足压干预区域承担的压力增加，第二足压干预区域之外的足底压力自然减少。
特别的，对于同一目标用户，在确定第一足压干预区域后进行设计，第一足压干预区域之外的部分承担的足底压力自然增加；又或，在确定第二足压干预区域后进行设计，第二足压干预区域之外的部分承担的足底压力自然减轻。也即，通过确定第一足压干预区域或第二 足压干预区域进行设计，即可实现压力调整的效果。当然，也可基于期望足压数据与实测足压数据，同时确定第一足压干预区域与第二足压干预区域，以在确定需进行压力分散的区域的同时限定用于承担分散后的压力的区域，如图3b所示实施例。
所述足压数据为即为鞋制品处于被穿着的状态下的鞋中底的不同区域的压力分布数据，包括静态压力分布与目标用户运动过程中的动态压力分布，用于指示鞋中底受力的分布情况。所述足压数据的压力分布为具有方向的压力矢量，例如，采用常见的三维直角坐标系，所述鞋中底的压力值可分别分解在不同的方向上。所述足压数据分布的区域范围即为鞋中底的三维空间区域，即所述足压数据包括压力分布的空间位置与压力矢量。基于力的相对性可知，所述足压数据即可表征目标用户在穿着中足部与鞋接触面的受力情况。
在某些实施方式中，所述足压数据可根据压力板或压力检测器采集获得。例如，通过指示所述目标用户的站立状态，令目标用户在赤足状态下足底接触压力板，从压力板接收对应的足底压力图，所述压力图即可用于表示足底的压力分布数据。具体的，在一种实施方式中，所述压力板上设置有压力传感器，且压力板连接至数字式压力分析系统。所述压力传感器可识别人体的触碰区域与触碰时间，即可采集在预设的时间长度内的压力，通过将传感器信号传输至的数字式压力分析系统，即可显示出对应的足底的压力分布图。所述压力分布图轮廓即显示为足底与压力板的接触面轮廓，压力分布图不同区域的压力数值即对应于在压力采集中该区域对应的足压压力值。所述压力分布图可表现为不同的形式，例如，根据采集的数据，所述压力分布图可显示为不同单元图块组成的接触面，每一单元图块内的数值即代表该单元区域的平均压力；同时，所述压力分布图中的数值可基于人为选择或压力分析系统自动选择单位而显示为不同的数值，例如选择以不同数量级的单位显示则可获得所显示数值不同的压力分布图，又或根据设定的压力级别作为显示单位：如每10Pa显示为数值1，并可选择采用比较规则如四舍五入的方式对每一单位区域的压力数值取整数。
在某些实施方式中，所述足压数据是通过统计获取的。例如，针对一定数量的目标用户群体，基于大数据分析确定人体自然状态下的压力分布规律，如足弓对应相对低压区，并获取体重、体重指数BMI等参数与压力数值的关系，由此可先根据目标用户的特征如体重特征划分其对应的群体类别，如对划分为体重数量级60～70kg的目标用户群体，基于此群体类别确定常规的足底压力分布；又如，所述大数据分析包括医疗数据统计分析，针对某一类或某些类别的病症如糖尿病、小儿麻痹等容易引发足部疾病的患病群体，基于医学统计分析确定该类患者常见的足底压力分布状态，由此基于目标用户的特征如疾病状态如糖尿病患者确定 其对应的群体类别，并获得该类目标用户群体的足压数据。
所述实测足压数据为不经由外界调整的状态下测量的人体足底压力，如赤脚自然站立的人体足底压力。在一种实现方式上，可确定相同的人体姿态下的实测足压数据(该足压数据为未经过调整的足压数据)设置对应的期望足压数据，如在无倚靠的自然站立状态下测量目标用户足部处于平面上的足压数据，基于此足压数据设置自然站立状态下的期望足压数据，并将第一足压干预区域的期望足压数据值设置为小于相应足部区域的实测值。在一种应用场景中，所述第一足压干预区域可以为自然站立状态下足部受压较大的区域，适应于舒适度与足部保护的需求，该区域内的期望足压数据值由对实测数据中对应区域进行压力分散调整后获得，则足压干预区域的期望足压数据减小。
请参阅图5及图6，分别显示为一实施例下足底压力分布的模拟图，其中图5为基于测量的人体测试压力分布的模拟图，图6即为经过调整后的期望足压数据对应的足底压力分布的模拟图。其中，每一单元格内的数值即表示为在该区域内的平均压力，由足底不同区域显示的数值即可获得对应的足底压力分布状态，该数值由实际足压值或期望足压值、以及选择的压力单位确定，对于同一足压分布模拟图，数值越大，即对应的单元区域内的平均压力越大。在所述压力分布图中，每一单元格的大小可基于选择设定，并不以实际测量的足压数据密度为限制，例如，图5显示的实测足底压力分布的模拟图中，每一单元格内显示的数值可以为1个压力传感器测量获得的压力值，也可以为排列为正方形的4个压力传感器的测量值的平均值，可基于显示足压分布规律而人为设定每一显示单元格的范围；同时，足压分布图中的数值基于对足压单位的选择而不同，对同一足压数据，可基于不同的压力单位设置显示为不同的数值，当然，在同一足压分布图中，不同单元格的数值均采用同一压力单位表示，也即在同一压力分布模拟图中，不同区域的单元格内的数值可用于表示不同区域的相对压力大小。
基于图5中对目标用户在自然状态下的足压数据，确定目标用户的足底范围内的相对高压区与低压区。如图5所示，在无调整的状态下，通常人体的足弓区域对应较小的压力值，如图5所示实施例中压力值显示为0的区域，在某些实际场景中，足弓部分区域与压力板不发生接触，即该区域的压力为0，相对高压区通常在脚掌部与后跟部(例如图5所示的实施例中数字70或76分布的区域)。对比如图6所示的期望足压分布图，可见相同的足底区域在调整前后对应为不同的压力数值，可选择将处于相对高压区的部分区域的压力分散至低压区域，改变在自然状态下的足底压力分布。
如图5所示，在无外部作用的自然状态下，人体的足弓区域通常对鞋底具有较小的压力或无压力，在某些实施方式中，基于对足部后跟区域或前掌区域的压力调整需要如减小高压区的压力峰值，将该区域的压力部分转移至足弓区域，以实现压力分散的效果，即呈现为如图6所示的压力分布状态；又或，基于确定的足压峰值对应的区域，为减小该压力峰值，将压力调整至压力峰值之外的前掌区域、后跟区域以及足弓区域。
在某些实施方式中，所述期望足压数据是基于测量获得的目标用户的实测足压数据及对应的医疗干预数据计算获得的。由目标用户的实测足压数据与医疗干预数据共同确定期望足压数据，确保鞋中底结构在以预期目标调整用户足部压力分布并具有预期的强度和可靠性。所述实测足压数据确定目标用户足部压力分布状态，由医疗干预数据确定所需进行的压力分布调整。
所述医疗干预数据即针对目标用户的身体状态所需要的或所预期矫正的足压分布数据。通过生理检测如腱反射和病理反射、肌力和肌张力、关节活动度、感觉(触觉/痛觉/本体感觉)、压痛、肿胀、皮肤状况(溃疡/颜色)等获得。所述医疗干预数据的确定与多项生理健康指标相关，用于减轻特定目标用户病症或降低目标用户的患病风险，又或，基于医疗数据分析，确定有益于足部养护的压力状态转化为预设的医疗干预数据。在一种实现方式中，根据足型扫描仪测量的足型数据与治疗方案确定医疗干预数据的区域及数值，例如针对足底具有溃疡区的目标用户，基于足部保护与病症疗养的需求，相应的溃疡区具有预期的压力数值范围，参考实测足压数据与医疗干预数据设计鞋中底的拓扑结构或晶格结构，实现预期的压力分布与目标用户穿着的触感；又如针对足部存在局部压力异常的目标用户，为治疗足底受力不均的状态，相应的局部压力异常区域的医疗干预数据即为减轻或消除足底受力不均对应的压力分布数据，参考实测足压数据与医疗干预数据，确定足压干预区域的压力转移区域与转移值，计算获取相应的期望足压数据。
在某些实施方式中，所述期望足压数据根据医疗干预数据所表征的目标用户所处的医疗阶段与实测足压数据获得。具体的，所述医疗干预数据包括目标用户的生理检测数据分析所得的目标用户在某一疾病上所处的阶段。
在一种实施方式中，对于足部未表现出明显的病变特征如足部无创口、无明显足部变形但由医疗数据体现出具有足底患病风险的目标用户，即针对处于预防状态或病变不明显的目标用户的足底养护或足底矫正，根据医疗统计分析确定处于该阶段的目标用户所需要的足压分布状态。例如，目标用户的足压峰值偏高但无明显的足部异常或疾病，将目标用户的足底 的相对高压区的足压峰值降低至正常的足压峰值即可避免足底病变发生，则由此确定的医疗干预数据即为实测足底压力中的相对高压区在医疗调整后的可防止或减轻足底压力引起足部恶化的压力数值范围，结合目标用户的实测足压分布，确定经过调整后的足底期望压力数据；又如，针对患有糖尿病或小儿麻痹等容易引发足部疾病但未发生明显足部病变的用户，可基于对目标用户在病症上所处阶段的医疗分析，确定后续的足底可能因疾病损伤的区域，以及防止或减小疾病损伤所需的区域对应的压力数值范围，由此确定的医疗干预数据联系实测足压数据设定目标用户的期望足压数据。
在一种实施方式中，对于足底发生如足底溃烂、胼胝、足骨畸形等可临床检测出明显足底病变的目标用户，可基于其足底疾病的疾病严重度评价确定适宜于治疗足底疾病或抑制足底恶化的压力分布状态，例如对于已存在足底溃烂的区域，需要尽量缓解该区域的压力值以抑制病态恶化，对照目标用户在无调整状态下的足压数据，即可确定需进行足压调整的区域与调节的压力值，即确定预期的适宜于该病症阶段的期望足压数据。
所述期望足压数据的设定可采用压力分布图的压力单位确定调整的单位量，所述单位量即将压力分布值在实际分布状态上进行增加或减小的调整的基本单位，如将分布图采用的压力单位的数值1即以1倍的单位压力大小作为调整的基本单位，基于实际测量的压力分布图上的数值，对于确定需要减小压力的压力干预区域，其期望压力数值为在实测压力数值减小1的整数倍，例如，对于处于足部疾病前期或预防阶段的目标用户，其足底压力峰值为在选定的压力单位下为70的单元区域，基于其医疗干预数据确定该压力峰值需降至50以下，则将调整后的期望足压数值设置为50或49或更小的自然数；又如对于存在足底创口目标用户，其足底外伤区域的期望足压数值为25以下，则将调整后的区域压力数值调整为25或更小的自然数。
在某些实施方式中，所述至少一个第一足压干预区域或/及第二足压干预区域中的晶格结构的受力强度与计算获得的期望足压数据及测量获得的脚型轮廓数据相关。
所述脚型轮廓为目标用户足部的三维轮廓，不同的轮廓形态对应压力在足底不同的分布，即足部受力点与受力大小不同。所述目标用户的脚型轮廓数据的获取方式包括由3D足部扫描仪扫描获得，又或基于双目摄像机拍摄的可见光图与深度图处理获得，所述脚型轮廓数据参数包括：足长、足宽、足趾高、足弓宽、足弓围、内踝高、外踝高、足跟宽及足后跟高等。
在某些实施方式中，所述目标用户的脚型轮廓数据是根据大数据统计分析获得的，如根据大数据对人体足部轮廓的采集，确定常见的脚型轮廓形式与部分特定的脚型轮廓形式，如 无足部疾病的躯体对应的脚型轮廓、先天性足部畸形分类对应的不同脚形轮廓。所述对大数据的统计分析还可将目标用户的脚形轮廓数据与身体特征相关联，如不同性别、脚长对应的脚形轮廓数据。以此，根据对目标用户群体的类别划分确定对应的脚型轮廓数据。
所述目标用户的脚型轮廓决定了压力分布的区域，由期望足压数据实现压力分布调整时顺应目标用户的脚型轮廓进行，以确定压力分布与在对应目标用户的足部的预期效果一致。例如，期望足压数据分布为减轻目标用户跖骨与后跟部压力值，将压力分散至足弓；考虑脚型轮廓，在将压力分散至足弓的同时需要确定压力值处于不引起足弓损伤的数值范围，基于目标用户的脚型轮廓确定对足压调整的范围及调整值的限制，并结合期望足压数据，设计晶格结构强度以实现预期调整功能。
在某些实施方式中，所述至少一个第一足压干预区域或/及第二足压干预区域中的晶格结构的受力强度与计算获得的期望足压数据、测量获得的脚型轮廓数据、以及步态数据相关。
所述步态数据包括目标用户在行走过程中的全身姿势和步态，包括步行节律、稳定性、流畅性、对称性、重心偏移、手臂摆动、诸关节姿态与角度、目标用户神态与表情、辅助装置(矫形器、助行器)的作用等。
所述步态数据的规律影响鞋中底在长期穿着状态下的压力分布。自然站立状态与行走状态通常对应不同的足部压力分布，再者，行走所引起的压力分布变化与目标用户的行走习惯相关，具有个体特异性。由所述步态数据反映的目标用户行走中的压力分配，与对目标用户设置的期望足压数据与脚型轮廓数据，确定在制造中鞋中底不同区域的拓扑结构或晶格结构强度。又或，基于不同目标用户的步行习惯，其步态数据中可反映出左脚和右脚可能具有的压力不对称的情况，基于此对一双鞋对应的两只鞋中底的拓扑结构或晶格强度采用不同的强度设计。
同时，所述步态数据与所述目标用户的身体机能相关，例如，年长者通常具有较低的步行速度与较小步幅，在行走中由双足支撑底面站立的时间变长。所述拓扑结构或晶格结构的强度与穿着中的人体触感相关，所述强度包括刚度或硬度，在对步态数据分析中，针对双足支撑期长度较大的目标用户，可将其拓扑结构强度或晶格结构强度设置为具有较高的韧度与较低硬度。
在某些实施方式中，基于对所述步态数据的分析，确定医疗干预数据。对比医疗测量的临床检查数据与步态数据的实验分析，对目标用户的病症进行综合评定，基于定量化、标准化的推断，确定对目标用户设置的医疗干预数据。所述期望足压数据、步态数据与脚型轮廓 数据对压力分配方式提供条件与限制，综合不同压力分配方案对比获取最优选方式，以进行晶格强度设计。
本申请在前述示例中提供了通过第一足压干预区域以及第二足压干预区域以调整鞋中底压力的实施例，对于以晶格结构或拓扑节结构为基本单元的鞋中底，本申请还提供了以下调整足压分布的实现方式：
在某些实施方式中，本申请的鞋中底的腰窝部设置有预设高度的隆起部分以支撑所述目标用户的足弓。请参阅图7，显示为申请的鞋中底在一实施例中的侧视图。所述腰窝部12对应于目标用户的足弓，腰窝部隆起部分121的预设高度与目标用户的足弓高度相匹配。
在某些实施方式中，所述腰窝部的隆起部分121具有预设高度以支撑所述目标用户的足弓。在自然的站立状态或步行状态下，人体足底受力的压力主要分布于脚掌部与后跟部。在进行足压压力分配的过程中，压力需转移至非足压干预区域如足弓区域。通过设置腰窝部隆起的预设高度与强度，对足弓部提供承受分散压力的接触面。
在一种实施方式中，所述腰窝部隆起部分121的高度是基于目标用户的脚型轮廓确定的，根据目标用户的足弓形态，使得腰窝部轮廓曲线与目标用户足弓轮廓曲线基本贴合。具体的，所述腰窝部的隆起部分121的受力强度与目标用户的期望足压数据及脚型轮廓数据相关。所述期望足压数据可以为基于测量目标用户的实测足压数据及对应的医疗干预数据计算获得。根据对目标用户的足底压力分配调整的优选方式，设计足底压力的期望分布图，并结合目标用户的脚型轮廓使得调整后的足底压力以预期的方式分布。所述腰窝部的轮廓设计与晶格结构的强度设计用以实现所采用的压力分配方案，确保鞋中底在被穿着状态下腰窝部以预期效果承担压力并具有可靠的强度。基于拓扑结构或晶格结构强度与受力关系的分析，将已知的压力分布为基础，计算获得拓扑结构或晶格结构的预期强度。
在某些实施方式中，所述腰窝部的隆起部分121的高度及其受力强度与计算获得的所述目标用户的足压数据及脚型轮廓数据及步态数据相关。由所述步态数据表征的目标用户的行走习惯偏好与身体状态，结合计算获得的期望压力数据与脚型轮廓，确定可由足弓部分实际承受的压力进行腰窝部拓扑结构或晶格结构强度设计。
在某些实施方式中，基于目标用户的足底状态，所述腰窝部的轮廓曲线与足弓轮廓曲线呈现不完全贴合的状态，例如，当所述目标用户的足弓区域存在损伤如足底筋膜撕裂等损伤时，在采用增大足底接触面减小足底高压区域的压力峰值时，所述腰窝部的轮廓设计基于目标用户的足弓轮廓曲线调整为不完全贴合状态，以使得贴紧筋膜损伤部位的足弓区域压力减 小。
通常来说，鞋中底在鞋制品中所承担的功能为减震缓冲，如在运动中吸收缓震与形状反弹，鞋中底的厚度与减震功能相关，亦决定目标用户在穿着中的触感如硬度等。所述鞋中底呈现为不均匀的厚度，用于适应对目标用户足部压力匹配的需要，同时，厚度值参考目标用户的身体状态决定。如图7所示，所述鞋中底的呈现为不均匀的厚度，在上表面的轮廓弧度与人体的足部的底面轮廓有一定的贴合，如鞋中底中部的腰窝部12对应的隆起与人体的足弓相对应。
所述鞋中底晶格结构的基本单元层数可基于鞋中底的预设三维轮廓与基本单元几何结构确定，例如，所述鞋中底层数可以为0.5层、1层、5层等，本申请不做限制。在某些实施例中，所述鞋中底晶格结构的基本单元在不同区域内为不同层数，例如，在第一足压干预区域内为1层，在第二足压干预区域为3层。
在所述鞋中底的不同区域，晶格结构的基本单元结构存在一定的变形处理，如在鞋前端区域处鞋中底厚度减小，将该区域晶格结构的基本单元减小以增大体积密度，用于确保鞋中底中薄弱区域的结构强度。
在某些实施方式中，所述鞋中底的预设厚度与测量获得的所述目标用户的形体数据、体重数据、脚形轮廓数据、步态数据、或足压数据中的至少一种数据相关。具体的，鞋中底的厚度影响其整体的弹性变形趋势与被穿着时目标用户的足底压力分布，对预设厚度的设置可改变目标用户的受力状态，因此，该预设厚度与目标用户受力的各项力学参数与对应的目标用户的触感相关。
例如，当所述目标用户的体重数据值较大，对应的鞋中底承受压力较大，在考虑用户穿着的舒适度的需求下，通常较厚的鞋中底具有更柔软的触感，则可相应的将目标用户的体重数据与鞋中底厚度设置为正相关的对应关系；又如，由所述目标用户的步态数据进行所述鞋中底的厚度设计，以满足步行中足底保护与步行安全，所述鞋中底厚度与步行中的关节姿态角度、稳定性相关，基于对鞋中底厚度与步态数据的关联分析，根据目标用户的步行姿态确定所述鞋中底的预设厚度。
所述足压数据与目标用户的体重数据、脚型轮廓数据以及步态数据相关，在一种实现方式中，所述鞋中底的预设厚度基于目标用户的足压数据确定。由足压数据表征的分别于静态与步行的动态下足底压力分布状态，确定对应的鞋中底的预设厚度。
所述形体数据包括目标用户的体格测量数据，例如对目标用户膝关节、踝关节等身体部 位的评定，用于确定有益于目标用户健康养护的运动模式，以确定对应的鞋中底的预设厚度。
在某些实施例中，所述鞋中底的预设厚度与目标用户的足压数据、形体数据、脚型轮廓数据等多项因素相关，特别的，所述鞋中底的预设厚度可能对不同的需求为相反的作用效果。例如，当鞋中底预设厚度过大，则不利于目标用户对底面的感知与稳定性，而弹性相应提升。在联系所述目标用户的形体数据、体重数据、脚形轮廓数据、步态数据、或足压数据等多项数据进行鞋中底厚度设计时，一种实施方式为，采用软件建模仿真，在构造所述鞋中底模型后对其施加目标用户对应的静态压力与步行的动态压力，并设置对应目标用户不同需求的性能分析指标，对不同的分析指标加权后计算总和，输出性能总和最佳的方案对应的鞋中底厚度。在某些实施方式中，所述不同分析指标的权重可基于目标用户的需求偏向与健康状态确定。
上述示例提供了通过确定腰窝部隆起高度或鞋中底厚度以调整鞋中底压力分布或性能的实现方式，在此，本申请还提供了另一基于确定鞋中底厚度或鞋中底三维轮廓以调整足压的实现方式。
在某些实施方式中，所述鞋中底包括对应目标用户脚后跟的后跟部，对应所述目标用户前脚掌的脚掌部，以及位于所述后跟部与脚掌部之间且对应所述目标用户足弓的腰窝部，其中，所述脚掌部设有至少一目标区域及与所述至少一目标区域相邻的至少一干预区域，所述至少一目标区域的截面厚度小于所述鞋中底的脚掌部的基准厚度，所述至少一干预区域的截面厚度大于所述鞋中底的脚掌部的基准厚度。
所述的目标区域所需实现的效果以及确定区域位置的方式可参照前述各示例所述的第一足压干预区域，即预期减小足压的区域。所述干预区域所需实现的效果以及确定区域位置可参照前述各示例所述的第二足压干预区域，即为预期将足压增大的区域。
在前述示例中，本申请提供了基于如体积密度、晶格体结构、打印材料、打印工艺、以及后处理工艺中的一种或多种调整区域的受力强度的实现方式，在此，所述目标区域与干预区域还可为通过确定截面厚度以调整受力强度，从而实现足压调整。
请参阅图8，显示为本申请的用于鞋类制品的鞋中底在一实施例中的结构示意图。
如图8所示的鞋类制品的鞋中底，包括：对应目标用户脚后跟的后跟部13，对应所述目标用户前脚掌的脚掌部11，以及位于所述后跟部13与脚掌部11之间且对应所述目标用户足弓的腰窝部12，其中，所述脚掌部11设有至少一目标区域151及与所述至少一目标区域151相邻的至少一干预区域152，所述至少一目标区域151的截面厚度小于所述鞋中底的脚掌部 11的基准厚度，所述至少一干预区域152的截面厚度大于所述鞋中底的脚掌部11的基准厚度，由此所述目标区域151及干预区域152分别对应的强度分布被调整，进而可实现基于目标用户个人的特定条件或特定群体用户的情况对其足底压力进行调整。
应当理解，所述鞋中底的区域与目标用户足底区域相对应，在此即可基于目标用户的足型轮廓确定鞋中底的区域，例如的鞋中底的大小或尺寸。在某些实施方式中，在已获取目标用户足底外轮廓的基础上，可进一步考虑穿着的舒适度及足部保护的需求确定所述鞋中底的轮廓，例如令足趾尖与鞋头设置一定距离，如大约0.95cm～1.27cm的范围。
所述脚掌部11设有至少一目标区域151及与所述至少一目标区域151相邻的至少一干预区域152。其中，所述目标区域151即为预期减小足压的区域，举例来说，所述目标区域151可根据所述目标用户的特定需求确定，例如为足部的指定保护部位、足部溃疡部位等需要将压力进行分散转移的区域，又或别的基于足底的舒适度或保护等需求进行压力调整分散的区域，其具体位置还可进一步基于目标用户的脚型轮廓与特定需求确定。
所述干预区域152即为预期将足压增大的区域，所述干预区域152可用以实现对目标区域151压力分担。应当理解，对同一目标用户，在足压调整前后鞋中底整体需承担的压力为不变，例如因目标用户的体重、体型、站姿、步态等自身固然条件与习惯导致其鞋中底的压力分布常态下的分布保持不变。当需要实现足底局部压力减小，则对应的需要其他区域分担压力，所述干预区域152即可作为对目标区域151进行压力分担的区域。
所述干预区域152与所述目标区域151相邻，在此，所述相邻可以为干预区域152的边界(也可称轮廓)与所述目标区域151的边界为相切或相接，又或为相离。应当理解，基于对目标区域151预期减小足压以及通过干预区域152预期增加足压以实现压力分担的特点，令干预区域152与目标区域151间不发生重叠即可。在一个实施场景中，例如，可在鞋中底脚掌部11预先确定目标区域151，由此在脚掌部11内的目标区域151之外区域中选定干预区域152。
在申请提供的各实施例中，所述的将足压增大均是在说明，针对某一特定区域(即本申请所述的干预区域)，相对比于未经干预的足压，例如赤脚站立时的足压，在穿着本申请的鞋中底形成的鞋类制品时，该特定区域的压力增大；类似的，所述的将足压减小为相比于未经干预的足压，目标用户在穿着本申请的鞋中底形成的鞋类制品时，该目标区域的压力减小。
本申请所述的足压(也称足压数据)即目标用户足底的压力分布数据，在一些实施例中也即鞋类制品处于被穿着的状态下的鞋中底的不同区域的压力分布数据，包括静态压力分布 数据与目标用户运动过程中的动态压力分布数据。
在本申请的某些实施方式中，所述目标区域设于对应目标用户第一跖趾关节处、以及第一拇指处中的一处或多处；以及，所述干预区域设于对应目标用户第二跖趾关节至第五跖趾关节之间。
通常来说，人体在静态(例如站立时)与运动中的动态所对应的足底压力分布中，前脚掌的第一跖趾关节处在不同状态中均为一高压区域。脚掌中第二跖趾关节至第五跖趾关节之间的压力相对于第一跖趾关节处的压力较小。
在某些情形中，对于特定的目标用户例如糖尿病足的患病群体，其足压在第一跖趾关节处的高压倾向尤为明显。针对于糖尿病足患者或糖尿病患者，通常其跖骨以及足跟部为胼胝高发区域，而医学上通常认为足底最大压强与足病变具有较高的相关性，糖尿病患者足底最大压强处即可能为足部溃疡发生处。第一跖趾关节处还可作为一拟定的保护区域，例如针对无明显足底疾病伤口的糖尿病患者，针对医学统计分析可获取的胼胝、溃疡等疾病高发区域，该疾病高发区域即可作为保护区域。
因此，在一些实施方式中，将所述目标区域设于第一跖趾关节处，即将此区域确定为需要减小足压的区域，对第一跖趾关节处足压异常如足压峰值过大目标用户或第一跖趾关节处为患病区的目标用户，基于本申请的鞋中底形成的鞋类制品即具有足底保护或疾病治疗的功效。
在本申请提供的各实施例中，所述治疗包括可导致预期的生理效果的防止性(即预防性)、阻断性、治愈性或缓和性处置。此外，“治疗”一词在此是指基于可部分或完全减轻、延迟发生、抑制进程、减轻严重性、和/或减少一种特定疾病、异常和/或医疗状况之一或多个病征出现机率的目的。
将与所述目标区域相邻的干预区域设于对应目标用户第二跖趾关节至第五跖趾关节之间，由此第二跖趾关节至第五跖趾关节间可分担第一跖趾关节处的压力。例如，在调整前后目标用户前脚掌的压力总值不变，但通过所述干预区域对目标区域的压力分担，目标区域的足压减小。在此设置下，脚掌部压力可呈现为压力分布的平均化(例如第一跖趾关节的压力减小且第二跖趾关节至第五跖趾关节之间压力增大)或高压区转移(例如高压区从第一跖趾关节处移动至第二跖趾关节至第五跖趾关节之间)。
在本申请的提供的一些实施例中，所述后跟部还设有至少一所述目标区域。即，所述后跟部也可设置预期将足压减小的区域。应当理解，通常人体足压的高压区域位于前脚掌的足 后跟，在一些场景中，当目标用户足后跟的足压峰值过大又或目标用户足后跟具有患病区域，即可在所述鞋中底的后跟部设置目标区域。
所述至少一目标区域的截面厚度小于所述鞋中底的脚掌部的基准厚度，所述至少一干预区域的截面厚度大于所述鞋中底的脚掌部的基准厚度。
在此，所述基准厚度为未经干预前鞋中底的各部分的常规厚度分布，举例而言，由于鞋中底的天然设计属性，所述鞋中底前脚掌部分的基准厚度通常情况下小于后跟部的基准厚度，应理解的，所述鞋中底的基准厚度在鞋中底不同位置的不同的。
在一些示例中可以为传统鞋中的鞋中底常规厚度分布。所述的传统鞋例如为脚掌部上表面大致呈平面，后跟部设置为略高出脚掌部的鞋。应理解的，整个鞋中底区域对应的所述基准厚度并不需要为同一定值，即，未经干预前的鞋中底不以厚度在不同区域均匀分布为限制。所述的未经干预前的鞋中底即为未基于目标区域或干预区域的足压增大或足压减小的目标进行结构调整的鞋中底。
举例来说，实际场景中，在确定目标用户的足型轮廓后，又或明确目标用户的足部大小以确定鞋中底尺寸后，即可确定鞋中底的三维轮廓，此时的鞋中底的三维轮廓对应的厚度分布即为基准厚度。
所述目标区域与干预区域的截面厚度与基准厚度相关。在某些实施方式中，所述基准厚度与测量获得的所述目标用户的形体数据、体重数据、脚形轮廓数据、步态数据及足压数据中的至少一种数据相关。鞋中底的基准厚度影响其整体的弹性变形趋势与被穿着时目标用户的足底压力分布，对基准厚度的设置可改变目标用户的受力状态，因此，该基准厚度与目标用户受力的各项力学参数与对应的目标用户的触感相关。在此，所述形体数据、体重数据、脚形轮廓数据、步态数据及足压数据所表征的数据，可参照前述实施例，此处不再赘述。
应当说明的是，例如上述实施例中考虑目标用户的脚型轮廓数据、步态数据等以确定基准厚度并非本申请所述的“干预”，在本申请提供的各示例中，所述的“干预”在于对鞋中底中不同区域进行压力分配，并藉由改变鞋中底局部区域的结构、厚度或材料等手段实现。
所述目标区域的截面厚度小于鞋中底的脚掌部的基准厚度。例如，所述目标区域为区域A，区域A对应于目标用户的足底区域A′，未经干预前的鞋中底的区域A″也对应于目标用户的足底区域A′，本申请的鞋中底中区域A的截面厚度小于未经干预前的鞋中底的区域A″的截面厚度。所述的截面厚度也在说明，所述目标区域具有一大于0的预设厚度。
在所述鞋中底的后跟部设置有目标区域的实施例中，同理，可令后跟部的目标区域的截 面厚度小于后跟部的基准厚度。
在此设置下，所述目标区域的结构强度相较于未经干预前强度降低，在鞋中底对应的鞋中底被穿着以承重的状态下，目标区域的受力强度减小，由此可实现足底压力分配。
类似的，所述干预区域的截面厚度大于鞋中底的脚掌部的基准厚度，例如，所述干预区域为区域B，区域B对应于目标用户的足底区域B′，未经干预前的鞋中底的区域B″也对应于目标用户的足底区域B′，本申请的鞋中底中区域B的截面厚度大于未经干预前的鞋中底的区域B″的截面厚度。如此，所述干预区域的结构强度增加，在承重状态下相应的可实现压力分担，受力强度增大。
在某些实施方式中，所述目标区域上表面相对目标用户足型轮廓呈下凹状态；所述干预区域上表面相对目标用户足型轮廓呈上凸状态。
请参阅图9，显示为本申请的鞋中底在一实施例中的部分区域的截面图。
在一实现方式中，令鞋中底下表面在足压干预前后不变，令所述目标区域151的上表面高度降低以使得目标区域151的截面厚度小于未经干预前鞋中底对应区域的基准厚度，所述目标区域151的上表面呈现为相对目标用户足型轮廓呈下凹状态；同时，令所述干预区域152上表面高度增加以使得干预区域152的截面厚度大于未经干预前鞋中底对应区域的基准厚度，所述干预区域152的上表面呈现为相对目标用户足型轮廓呈上凸状态。
请结合参阅图10a及图10b，其中，图10a显示为本申请的鞋中底在一实施例中的截面图，图10b显示为图10a所示的鞋中底与鞋楦或目标用户接触的截面图。
如图所示，鞋中底包括脚掌部11、腰窝部12及后跟部13。所述目标区域151相对目标用户足型轮廓呈下凹状态，在此设置下，当目标用户穿着由此鞋中底形成的鞋类制品时，目标用户足底可预先接触所述干预区域(图中未予以显示)，干预区域即可实现压力分担效果，所述目标区域151对应的足底区域例如患病区域对目标用户提供的支持力减小；在一种情形中，患病区域与鞋中底不发生接触，由此该区域的压力降低为0；在另一中情形中，目标用户的足底预先接触并踩踏至目标区域151之外的其他区域例如所述干预区域，其他区域在被踩踏变形后目标区域151对应的患病区域才接触鞋中底，在此变形过程总中其他区域承担了部分足底压力，患病区域需分担的足压变小。应当说明的是，图10a及图10b所示实施例仅用于说明所述目标区域相对目标用户足型轮廓的接触状态，而不用于限制本申请的目标区域的具体位置；同时，图10a及图10b显示为所述鞋中底的一个截面图，不能用于限制鞋中底整体与目标用户足部的接触状态。
在某些实施方式中，所述目标区域朝向目标区域之外区域呈上表面高度渐变过渡，以令目标区域相对目标用户足型轮廓呈下凹状态；或，所述干预区域朝向干预区域之外区域呈上表面高度渐变过渡，以令干预区域相对目标用户足型轮廓呈上凸状态。
在此设置下，所述目标区域朝向目标区域之外的强度变化呈渐变过渡，即可减小目标区域边界处的压力突变以使其在一预设阈值之下。在此，所述预设阈值可基于医学数据或鞋制品性能设定，如当足压存在过大的突变时容易产生足底刺痛，在此，可基于医学分析确定足压突变的阈值以减轻或消除不适感，又如当鞋中底不同区域承受的压力值存在过大突变，则缓冲功能可能被削弱，在此可减小边界区域的压力突变以实现渐变过渡；再者，还可通过鞋类制品的制造工艺(标准)进行确定，例如，确定适合鞋底缓冲的压力变化状态，以增强鞋中底的缓冲功能或鞋中底的耐冲击、磨损等性能。
同理，所述干预区域朝向干预区域之外的强度变化呈渐变过渡，如此可减小干预区域边界处的压力突变，在鞋中底被穿着的状态下，可令干预区域对应承担的足压为逐渐变化。通常的，在此连续变化的压力状态下，鞋中底具有较好的缓冲能力，不同区域间可有效实现压力传递与分担；同时，减缓人体穿着态下局部压强过大的不适触感。
举例来说，在一实际场景中，在所述目标区域或干预区域的边界区域可设置为以一定坡度例如30°、45°、60°等朝向目标区域或干预区域外延伸；当然，所述目标区域或干预区域的边界区域还可以弧面或曲面朝向区域外延伸。
在某些实施方式中，所述目标区域的截面厚度与基于目标用户的期望足压数据确定的所述目标区域、干预区域的受力强度相关；所述干预区域的截面厚度与基于目标用户的期望足压数据确定的所述目标区域、干预区域的受力强度相关。
所述期望足压数据为对目标用户预期的足压分布数据。通过设置所述目标区域与干预区域对应的截面厚度，可令目标用户在穿着本申请的鞋中底的状态下其足压分布为预期的足压分布数据，在一些实施例中，所述期望足压数据即经过干预的足压数据。
通常的，所述期望足压数据为鞋中底整体区域的预期足压分布，因此在获得所述期望足压数据后可计算获得鞋中底整体区域的结构强度分布，基于所述期望足压数据获得的目标区域与干预区域对应的结构强度，可进行所述鞋中底中目标区域与干预区域的截面厚度设计。
在一些实施方式中，所述期望足压数据可基于目标用户的实测足压数据确定，其实现方式可参照前述实施例。在另一些实施方式中，所述期望足压数据与目标用户的实测足压数据及医疗干预数据相关；其中，所述目标区域的期望足压数据小于所述目标区域的实测足压区 域，所述干预区域的期望足压数据大于所述干预区域的实测足压数据。
在一实现方式中，所述期望足压数据根据医疗干预数据所表征的目标用户所处的医疗阶段与实测足压数据获得。所述医疗阶段例如可参照前述实施例中由医疗干预数据包括的目标用户的生理检测数据分析所得的在某一疾病上所处的阶段，即目标用户的疾病体征或严重程度。
同时，所述期望足压数据还可基于目标用户足型轮廓数据确定。对所述脚形轮廓的确定方式，此处不再赘述。应当理解，目标用户的脚型轮廓决定了压力分布的区域，由期望足压数据实现压力分布调整时顺应目标用户的脚型轮廓进行，以确定压力分布与在对应目标用户的足部的预期效果一致。
所述目标区域的截面厚度与基于目标用户的期望足压数据确定的所述目标区域、干预区域的受力强度相关；所述干预区域的截面厚度与基于目标用户的期望足压数据确定的所述目标区域、干预区域的受力强度相关。应当理解，鞋中底不同区域的结构强度与该区域预期承担的足压相关，举例来说，当干预区域的结构强度较大，鞋中底在穿着中的被踩踏状态下压力易于自然分配至干预区域。
通常来说，区域的截面厚度与该区域的结构强度呈正相关。基于截面厚度与结构强度的对应关系、以及结构强度与受力强度(即足压)的对应关系，如此，以目标用户的期望足压数据为基础，即可确定目标区域与干预区域对应的结构强度，从而计算获得目标区域与干预区域分别对应的截面厚度。在一示例中，鞋中底的截面厚度与结构强度的对应关系、以及结构强度与受力强度(即足压)的对应关系确定后，对所述目标区域的截面厚度可由目标区域的预期受力强度确定，所述干预区域的截面厚度可由干预区域的预期受力强度确定。
为说明所述鞋中底实现的足压分配效果，本申请还提供了以下实施例：
请参阅图11及图12，其中，图11显示为自然状态下人体足压分布测试的模拟图，图12经本申请的通过目标区域与干预区域调整足压的鞋中底干预后的人体足压分布测试的模拟图，其中，图11与图12对应的压力分布模拟图的压力数值以同一压力单位显示。
如图11所示目标用户在自然状态下(如赤脚站立)的实测足压数据，确定目标用户的足底范围内的相对高压区与低压区。如图11所示，在无干预的状态下，通常人体的足弓区域对应较小的压力值，呈如图11所示压力值显示为0的区域，在某些实际场景中，足弓部分区域与压力板不发生接触，即该区域的压力为0，相对高压区通常在脚掌部与后跟部(例如图11所示的实施例中数字脚掌部的压力值为60或后跟部的压力值为62的区域)。如图12所示的 干预后足压分布图，在设置于脚掌部的目标区域与干预区域中，目标区域对应的足压相对图11的对应区域足压减小，同时，干预区域对应的足压相对图11的对应区域足压增大。
如此，在自然状态下的目标用户脚掌部的高压区压力被分散，可令目标区域的压力峰值减小以达到预设范围内。所述预设范围可基于目标用户的具体需求确定，例如，当本申请的鞋中底用于对步态或足型引起的异常足压矫正，所述预设范围可以为正常足压范围，又如，当所述鞋中底提供于具有足部溃疡的目标用户，所述预设范围可基于目标用户的治疗需求确定。
所述目标区域与干预区域的截面厚度与基准厚度相关。在某些实施方式中，所述基准厚度与测量获得的所述目标用户的形体数据、体重数据、脚形轮廓数据、步态数据及足压数据中的至少一种数据相关。鞋中底的基准厚度影响其整体的弹性变形趋势与被穿着时目标用户的足底压力分布，对基准厚度的设置可改变目标用户的受力状态，因此，该基准厚度与目标用户受力的各项力学参数与对应的目标用户的触感相关。所述形体数据、体重数据、脚形轮廓数据、步态数据及足压数据所表征的内容以及确定方式可参照前述实施例，此处不再赘述。
应理解的，本申请在此提供的由所述目标区域与干预区域的截面厚度调整足压的实施方式与前述的藉由第一足压干预区域与第二足压干预区域调整足压的实施方式，又或将第一足压干预区域或/及第二足压干预区域设置为由区域外朝向区域内的足压呈现为渐变过渡的实施方式，又或将腰窝部设置有具有预设隆起高度的实施方式，其均是在调整鞋中底的足压分布；更重要的是，前述实施方式并不相互排斥，因此，本领域技术人员在获悉本申请公开的实施例后，可自行选择采用其中的一种或几种方式的组合以实现对鞋中底的足压调整。
例如，对于设计通过目标区域与干预区域调整压力分布的鞋中底，在某些实施方式中，本申请的鞋中底的所述腰窝部具有预设高度的隆起部分以支撑目标用户的足弓；在一种实现方式中，所述腰窝部的隆起高度例如可通过目标用户的足型轮廓确定；在又一实现方式中，基于目标用户的足底状态，所述腰窝部的轮廓曲线与足弓轮廓曲线呈现不完全贴合的状态，例如，当所述目标用户的足弓区域存在损伤如足底筋膜撕裂等损伤时，在采用增大足底接触面减小足底高压区域的压力峰值时，所述腰窝部的轮廓设计基于目标用户的足弓轮廓曲线调整为不完全贴合状态，以使得贴紧筋膜损伤部位的足弓区域压力减小；在又一实现方式中，所述腰窝部的隆起部分的高度及其受力强度与计算获得的所述目标用户的期望足压数据、脚型轮廓数据、及步态数据相关。
同时，在一些实施例中，所述鞋中底由3D打印的拓扑结构或多个晶格结构组成。对于晶 格结构或拓扑结构的受力强度的确定方式，还可参照前述实施例。例如，在某些实施方式中，所述鞋中底的晶格结构的受力强度与晶格结构的体积密度、晶格体结构、晶格体材料、打印材料、打印工艺以及后处理工艺中的至少一种相关；或，所述鞋中底的拓扑结构的受力强度与拓扑结构的体积密度、打印材料、打印工艺、以及后处理工艺中的至少一种相关。
例如，当所述鞋中底为采用3D打印工艺制造，通常成型后的鞋中底强度性能与打印材料相关，在此，可基于对打印材料的选择可形成结构强度不同的实体，在某些示例中，确定所述晶格结构或拓扑结构的受力强度时可预先确定打印材料。对于所述体积密度、打印材料、打印工艺、以及后处理工艺对拓扑结构的受力强度的影响方式，或体积密度、晶格体结构、晶格体材料、打印材料、打印工艺以及后处理工艺对晶格结构的受力强度的影响方式，还可参照前述实施例，此处不再赘述。
在一些示例中，所述晶格结构的体积密度与晶格杆径粗细、晶格壁面厚度、晶格大小、以及成型后晶格杆体密度相关；所述拓扑结构的体积密度与拓扑结构的杆径粗细、壁面厚度、成型后拓扑结构杆体或面体密度相关。
在某些实施方式中，所述拓扑结构或晶格结构是通过3D打印的方式获得的，所述3D打印方式包括丝材熔融挤出、材料微滴喷射、粉材平铺熔化、粘合剂喷射、或光敏树脂叠层固化打印。具体的，将所述鞋中底的拓扑结构或晶格结构对应的结构模型与性能参数如强度等输入至所述3D打印设备的控制装置，所述3D打印设备的能量辐射装置在控制装置的控制下，投射所述拓扑结构或晶格结构对应的图像与结构强度对应的辐射能量密度，将待固化材料以预设的三维结构与强度打印为所述鞋中底的实体。
在某些实施方式中，所述拓扑结构或晶格结构的材料包括光固化树脂材料、热塑性橡胶(TPR)、热塑性弹性体；其中，所述热塑性弹性体包括聚氨酯弹性体(TPU)、尼龙弹性体(TPAE)、聚酯弹性体(TPEE)、EVA弹性体及有机硅弹性体。所述晶格结构材料可以为上述任意一种，又或为两种以上材料的混合物。
其中，所述热塑性弹性体是常温下具有橡胶的弹性，高温下具有可塑化成型的一类弹性体，为共聚物或聚合物的物理混合物(通常是塑料和橡胶)，由具有热塑性和弹性体特性的材料组成。通常，热塑性塑料在制造中相对容易使用，例如通过注塑成型。
在某些实施方式中，所述拓扑结构或晶格结构的材料还可以为聚丙烯、丙烯腈丁二烯苯乙烯(ABS)、聚碳酸酯(PC)、PC-ABS、PLA、聚苯乙烯、木质素、聚酰胺、聚酰胺泡沫、具有诸如玻璃或金属颗粒的添加物的聚酰胺、甲基丙烯酸甲酯-丙烯腈-丁二烯-苯乙烯共聚物、诸 如聚合物-陶瓷复合材料的可吸收材料、以及其他类似的适宜于鞋中底制作的材料，所述拓扑结构或晶格结构采用的材料不以上述例举为限制。
某些实施方式中，所述鞋中底还包括由3D打印一体成型于所述鞋中底顶部表面的缓冲层。请参阅图13，显示为本申请的鞋中底在一实施例中的缓冲层及鞋中底示意图。如图13所示，所述缓冲层14设置在鞋中底晶格结构的表面，用于在穿着过程中为用户提供足够的缓冲力。
在某些实施方式中，所述缓冲层14由3D打印的多个晶格结构组成。所述缓冲层14中晶格结构的杆径或壁厚小于所述鞋中底中晶格结构的杆径或壁厚，且所述缓冲层14中晶格结构的晶格体积小于所述鞋中底中晶格结构的晶格体积。所述缓冲层14与所述鞋中底通过3D打印一体成型，基于晶格结构的不同设计与对应的不同功能将鞋中底与缓冲层14区分开。所述晶格结构的基本单元连接杆直径或共用面壁厚与所述晶格结构的强度有关，所述缓冲层14采用小杆径或薄壁的结构，并设计为小体积的晶格基本单元组成，则在保证所述缓冲层14的强度的同时，通过小杆径或薄壁的基本单元连接减小缓冲层14的硬度，在鞋中底表面形成一层硬度低、弹性性能佳并具有柔软触感的缓冲结构，进一步削弱足底与鞋中底接触的压力冲击。
在某些实施方式中，所述缓冲层14由3D打印的拓扑结构组成，所述缓冲层14中拓扑结构的杆体杆径小于鞋中底拓扑结构中的杆体杆径；又或，所述缓冲层14中拓扑结构的节点连接数小于所述鞋中底拓扑结构中的节点连接数，以减小缓冲层硬度，使其易于发生弹性变形，实现缓冲功能。
所述缓冲层14的轮廓可顺应所述鞋中底上表面的轮廓，在实际打印中贴合所述鞋中底上表面打印形成一体的结构。所述缓冲层14可设计为均匀厚度或不均匀厚度，通常来说，所述缓冲层14厚度远小于鞋中底厚度，顺应所述鞋中底的轮廓设计。所述缓冲层14的外围轮廓可基于鞋中底的轮廓获得，例如将缓冲层14下表面外轮廓设计为与鞋中底上表面外轮廓相同，形成在鞋中底上无突变的自然连接。
在某些实施方式中，所述缓冲层14的轮廓设计与拓扑结构或晶格结构设计还与所述目标用户的期望足压数据、步态数据、脚型轮廓等相关，如所述缓冲层14上表面轮廓可顺应目标用户脚型轮廓设计。在实际行走中，所述鞋中底跟随缓冲层14变形，经由缓冲层14对脚底冲击吸收，而后由所述鞋中底提供对足底的支持力即分配调整后的压力。

在某些实施方式中，所述下贴合面沿着所述鞋中底10的底部轮廓呈环形结构。所述下贴合面的外轮廓顺应所述鞋中底10下表面外轮廓，并采用环形结构减轻鞋底重量，在环形结构的上、下接触面上进行鞋中底10与鞋大底30的粘接。
基于本申请提供的用于鞋类制品的鞋中底，针对不同的目标用户，根据目标用户自身的个性化需求与特点如步行畸形状态或步行习惯、脚形轮廓、生理状态如足底健康、下肢关节、身体稳定性、原始的足压分布状态等进行量化，将实际测量获得的数据进行分析评价并与鞋中底的结构设计关联，基于目标用户的不同需求选择鞋中底的预设厚度与鞋中底拓扑结构或晶格结构的三维轮廓及鞋中底不同区域的结构强度，以实现基于目标用户个人的特定条件对其足底压力进行调整；再者，本申请的鞋中底中对承压不同的足压区域压之间设计为过渡渐变形式，可使鞋中底具有良好的缓冲性能。
本申请在第二方面还公开了一种鞋类制品，其包括：鞋大底，用于接触地面；如上述各实施例中任一实现方式所述的鞋中底，以及结合于所述鞋中底顶部周沿以包裹目标用户脚面 的鞋面。
请继续参阅图15，如图15所示，所述鞋类制品包括鞋中底10、鞋面20以及鞋大底30。针对所述鞋大底与鞋面分别的结构、材质以及与鞋中底的结合方式还可参照前述实施例。
在某些实施方式中，所述鞋面20的尺寸或张弛度与测量获得的目标用户的脚型轮廓数据相关。例如，基于所述目标用户的脚型轮廓数据，将所述鞋面20的尺寸与张弛度设计为贴合于所述目标用户的足面轮廓；又或将所述鞋面20设计为鞋面20内轮廓与目标用户的足面之间为预设的间隙。基于目标用户的脚面宽度与高度，选择设计所述鞋面20的尺寸与张弛度。
所述尺寸即鞋面20三维轮廓的大小，所述张弛度即所述鞋面20的可调整性或弹性，可用于评价所述鞋面20的纵向、横向的可延展性及折弯特性。
在某些实施方式中，所述鞋面20的尺寸或张弛度与测量获得的目标用户的步态数据相关。基于所述目标用户的步态数据，确定目标用户在运动状态下的足面状态以及弯折度等足面轮廓的变化，由此确定所述鞋类制品鞋面20的尺寸或张弛度，例如，在容易产生弯折的脚掌部选择高延展性的材料以增加弯折区域的张弛度。
在某些实施方式中，所述鞋面20的尺寸或张弛度与测量获得的目标用户的脚型轮廓数据与步态数据相关。由目标用户在静止状态与运动状态的足面轮廓与运动习惯对鞋面20的影响，选择相适应的鞋面材料与鞋面结构设计。
在某些实施方式中，所述鞋面20的设计还参考所述目标用户的足部健康状态。例如，对于足面具有创伤的目标用户，基于医疗养护的目的，可选择为柔性且质地轻盈的透气性材料制作鞋面20，并确保鞋面20具有足够的张弛度。
在某些实施方式中，所述鞋类制品为矫形鞋。所述矫形鞋即为对应于需要进行足部矫正的用户群体适用的具有矫正功能的鞋类制品，也即，有助于使不正常足部保持或基本保持正常步态的鞋类制品。例如对于因先天足部畸变，后天足部疾病如小儿麻痹引起的足踝病变，足部老化，以及步态习惯不佳引发的足部变形等因素使得足部异常的用户所特别制作的鞋类制品。具体的，基于对目标用户的不同的足部状态的压力分布采集与医疗状态分析，并结合其脚型轮廓，依照本申请提供的鞋类制品的鞋中底及鞋面、鞋大底的设计方法确定对应的鞋类制品结构与材料。

在此，本申请提供的鞋类制品，针对不同的目标用户，可将目标用户自身的个性化需求与特点如步行畸形状态或步行习惯、脚形轮廓、生理状态如足底健康、下肢关节、身体稳定性、原始的足压分布状态等关联至鞋中底的结构，由此确定对目标用户足压调整方式，例如基于目标区域及干预区域，并在鞋中底的目标区域将截面厚度设置为小于基准厚度，将干预区域的截面厚度设置为大于基准厚度，又如基于第一干预区域与第二足压干预区域，又或基于确定腰窝部隆起高度等，由此可实现鞋中底不同区域的强度调整，基于目标用户个人的特定条件对其足底压力进行调整，并可基于目标用户需求确定鞋面结构。
本申请在第三方面还提供了一种用于鞋类制品的鞋中底的三维数据处理方法，所述三维数据的处理方法可用于形成3D打印设备的三维数据切片。

在某些实施方式中，S100中还包括在鞋中底模型区域内设置晶格结构的基本单元或在鞋中底模型三维轮廓内设置拓扑结构的步骤，所述拓扑结构或为晶格结构的多个基本单元的结构以及属性与预期的鞋中底拓扑结构或晶格结构的强度有关，根据预期的鞋中底模型对应实体强度确定拓扑结构或晶格结构的强度设计，以确定拓扑结构在不同区域的结构特性，或确定晶格结构在鞋中底中不同区域的基本单元形式并进行建模。在具体实现方式上，可利用预置的为晶格结构的多个基本单元对目标用户的鞋中底进行建模，以形成为晶格结构的鞋中底模型；又或，预先确定三维鞋中底模型轮廓，基于选用的晶格结构基本单元在鞋中底模型中进行填充；再或，可利用拓扑结构对目标用户的鞋中底进行建模以形成预设的鞋中底模型轮廓；又再或在确定鞋中底模型轮廓后以拓扑结构进行填充。

在某些实施方式中，所述腰窝部具有预设高度的隆起部分用于吻合所述目标用户的足弓。所述腰窝部的隆起高度与三维鞋中底模型的实体结构的受力强度相关，即关联于鞋中底的足压分布，具体确定腰窝部的隆起高度的方式还可参照前述实施例。
在步骤S110中，利用获得的目标用户的足压数据及脚形轮廓数据对所述三维鞋中底模型进行处理以在所述三维鞋中底模型中的后跟部和/或脚掌部分确定至少一个第一足压干预区域。

在某些实施方式中，所述目标用户的足压数据及脚形轮廓数据是通过测量或统计获取的。具体的，所述目标用户的足压数据及脚形轮廓数据的确定方式，还可参照本申请第一方面提供的实施例。
在某些实施方式中，所述至少一个第一足压干预区域或/及第二足压干预区域中的拓扑结构或晶格结构的受力强度与计算获得的期望足压数据相关，所述期望足压数据小于对应所述至少一个第一足压干预区域的实测足压数据；所述期望足压数据大于对应所述至少一个第二足压干预区域的实测足压数据。
即如本申请第一方面提供的实施例所述，所述第一足压干预区域为预期减小足压的区域，所述第二足压干预区域为预期增大足压的区域。
基于所述第一足压干预区域内拓扑结构或晶格结构受力强度的弱化值，或基于第二足压干预区域内拓扑结构或晶格结构受力强度的强化值，确定对应的区域内体积密度或打印材料等参数的调整。

在基于顶面曝光的3D打印设备中，打印基准面设置于待固化材料的上表面即与空气的接触面。在完成一层的固化后，附着在构件平台上的固化层在Z轴驱动机构的带动下下降，构件平台下降距离与待固化材料表面之间形成的预设高度为下一分层图像对应的厚度，该固化层上表面与打印面之间被填充后形成新的待打印层。
在步骤S240中，判断三维鞋中底模型是否打印完毕，若否，则相继执行S210、S220、S230；若是，则结束。通过执行上述步骤，经过多次填充、照射和分离操作，将各固化层累积在构件平台上以得到三维鞋中底模型对应的实体结构。
