Opportunities and limits of the working space model in product development

通过界面模拟工作空间的行为和工作空间的相互作用是产品开发中的一项开放挑战，应通过对技术产品中的工作效应的现象学描述来解决，使经验者知道如何在开发过程的早期跨科学领域获得。到目前为止，对充满媒介的工作空间在产品开发的分析和综合中的作用的描述大多失败了，要么是因为专家的经验知识作为现象学工作空间模型的适用性有限，要么是因为这种模型的接受度有限。工作空间模型的目标是根据可获得的数据对工作空间功能进行早期和定量的评估，从而产生对基本工程问题的物理动机评估。该模型需要与开发过程中使用的专家工具兼容，并且需要在现有数据的有限成熟度的基础上提供有意义的结果。因此，需要解决以下研究主题：-在充满介质的工作空间中的过程(物质、电荷、…)由于重要的和有代表性的功能可以针对静态和暂态情况进行现象学建模，因此故障或功能失调的风险和所需工艺的性能可以作为早期产品开发的决定性标准进行评估。-平衡方程(能量、物质、电荷、…)的耦合和状态方程(一般气体方程，…)能够使专家的经验知识在产品开发的早期获得。-工作空间模型可以通过单个工作空间的特征量来捕捉样本效果的物理限制，并允许在概念设计阶段对变量进行比较评估。因此，我们的目标是改进工作空间模型，以定量描述产品开发中技术系统的特性。由于所需的聚焦重点首先是在工作空间内缓慢变化的过程和层流条件下的气体和液体(牛顿)介质。该模型应帮助产品开发人员评估不需要的风险和期望功能的性能。为了支持模型创建，一方面为技术系统的不同功能建立了样本工作空间模型，另一方面为限制情况建立了样本工作空间模型。此外，需要一个程序来对关键过程的功能和操作条件进行数学分析，需要对该程序进行测试和验证。需要汇编关于将工作空间模型转化为虚拟发展工具的机会的信息，以便描述改进后的工作空间模型的复杂问题。

Modelling of working space behavior and of interaction of working space via the interfaces is an open challenge in product development that is to be addressed by phenomenological description of working effects in technical products making experiential know how accessible early in the development process across scientific domains. So far the description of functions in media filled working spaces in analysis and synthesis in product development fails mostly either due to the limited applicability of experiential know how of experts as a phenomenological working space model or doe to the limited acceptance of such models. The goal of a working space model is the early and quantitative assessment of working space functions based on available data yielding physically motivated evaluation of basic engineering questions. The model needs to be compatible with expert tools used in the development process and need to deliver meaningful result based on the limited maturity of the data available. Thus, the following research topic need to be addressed:- Processes in media filled working spaces (material matter, electric charge, …) as important and representative functions can be modelled phenomenologically for static and transient cases, the risk of mal- or dis-function and the performance of wanted processes can be evaluated as a decisive criterion in early product development.- Coupling of balancing equations (Energy, matter, electric charge, …) and equations of state (General gas equation, …) for the working spaces is enabled to make experiential knowledge of experts accessible early in product development.- Physical limits of sample effects can be captured by the working space model through characteristic quantities of single working spaces and allow for a comparative assessment of variant during concept design phase. Hence, the goal is the enhancement of the working space model for the quantitative description of properties of technical system in product development. Due to the required focusing emphasis is first on gaseous and liquid (Newtonian) media under the assumption of slowly varying processes and laminar flow conditions in the working space. The model shall assist the product developer in evaluating the risk of undesired and the performance of desired functions.To support model creation a collection of sample working space models is established for different functions of technical systems on the one hand and limiting cases on the other. Furthermore, a procedure is required to analyze critical processes functions and operational conditions mathematically, the procedure needs to be tested and validated. Information about opportunities to cast the working space model into a virtual development tool needs to be compiled in order to describe complex problems with the enhanced working space model.
