Optimal human-machine interfaces support the user and increase the user comfort. A good example of this is a conventional static handle, which still represents a compromise for various users and operating scenarios. This is due to its unchangeable shape, which means that it can only be used optimally for a specific application and few operators.The development and realization of an adaptive handle with situational, continuous shape adaptation, depending on the user anthropometry and the operating scenario, requires the consideration of a multitude of different requirements and boundary conditions. This requires interdisciplinary collaboration between the disciplines of ergonomics and engineering design. On the one hand, a description of the design parameters to be varied for specific anthropometry and operating scenarios is missing. On the other hand, there is a lack of suitable effective principles for the technical realization of the required adaptivity. Additive manufacturing (AM) extends the design freedom of established conventional manufacturing processes and thus opens up new design possibilities for the realization of continuous shape changes in the sense of adaptivity. An advantage of AM is the possibility of combining different materials in one component without the need for an additional joining process. The potential of AM with regard to the realization of an adaptive handle design has not yet been explored.Therefore, this research project aims to investigate and realize an adaptive handle using AM-specific effective principles. This approach is facilitated by a close interaction between the disciplines of ergonomics or industrial design engineering and engineering design. The conduction of empirical studies with test persons is the basis for a determination of optimal design parameters for an adaptive handle: structure, shape and surface. Empirical studies are utilized to identify relevant design parameters, which have to be adaptive in terms of universal design. On this basis, a systematic identification, evaluation and experimental investigation of AM-specific effective principles for the realization of shape-variable structures is carried out. The usability is examined and ensured by means of additively manufactured prototypes in test person studies. The participation of persons with different anthropometry as well as physical impairments is a central aspect in the studies. Subjective interviews as well as a measurement of surface pressure are used as parameters for an evaluation of suitability of adaptive handle designs. Thus, the potential of AM effective principles with regard to a realization of adaptive product designs can be evaluated and validated using the example of handles.

优化的人机界面支持用户，增加用户舒适度。一个很好的例子是传统的静态句柄，它仍然代表着对各种用户和操作场景的折衷。这是因为它的形状是不变的，这意味着它只能用于特定的应用和少数操作员的最佳使用。根据用户人体测量和操作场景，开发和实现具有情景、连续形状适应的自适应手柄需要考虑多种不同的要求和边界条件。这需要人机工程学和工程设计学科之间的跨学科合作。一方面，缺少针对特定人体测量和操作场景而改变的设计参数的描述。另一方面，缺乏在技术上实现所需适应性的适当有效的原则。相加制造(AM)扩展了传统制造工艺的设计自由度，从而为实现适应性意义上的连续形状变化开辟了新的设计可能性。AM的一个优点是可以将不同的材料组合在一个组件中，而不需要额外的连接过程。AM在实现自适应手柄设计方面的潜力还没有被发掘，因此，本研究项目旨在研究并实现一种使用AM特有的有效原理的自适应手柄。人类工程学或工业设计工程与工程设计学科之间的密切互动促进了这种方法的发展。对受试者进行的经验研究是确定自适应手柄的最佳设计参数的基础：结构、形状和表面。利用实证研究来确定相关的设计参数，这些参数必须在通用设计方面具有适应性。在此基础上，对AM特有的实现变形状结构的有效原理进行了系统的识别、评价和实验研究。在测试者研究中，通过添加制造的原型来检查和确保可用性。具有不同人体尺寸和身体残疾的人的参与是研究的一个中心方面。主观访谈以及表面压力的测量被用作评估适应性手柄设计的适宜性的参数。因此，AM有效原则在实现适应性产品设计方面的潜力可以使用手柄的例子来评估和验证。
