Opportunities and limits of the working space model in product development

工作空间行为和工作空间通过界面的相互作用的建模是产品开发中的一个开放性挑战，这将通过对技术产品中工作效果的现象学描述来解决，从而在跨科学领域的开发过程中早期获得经验知识。产品开发中的分析与综合工作空间中的功能描述，由于专家经验知识作为现象学工作空间模型的适用性有限，或者由于对这种模型的接受程度有限，至今未能得到有效的描述。工作空间模型的目标是根据现有数据对工作空间功能进行早期和定量评估，从而对基本工程问题进行物理评估。该模型需要与开发过程中使用的专家工具兼容，并需要根据现有数据的有限成熟度提供有意义的结果。因此，需要解决以下研究课题：-在充满介质的工作空间（物质，电荷，.）中的过程作为重要的和代表性的功能，可以在静态和瞬态情况下进行现象学建模，可以在早期产品开发中评估故障或功能障碍的风险和所需过程的性能作为决定性标准。工作空间的平衡方程（能量、物质、电荷等）和状态方程（一般气体方程等）的耦合使得专家的经验知识能够在产品开发的早期获得。样品效应的物理极限可以通过单个工作空间的特征量由工作空间模型捕获，并允许在概念设计阶段对变体进行比较评估。因此，我们的目标是加强工作空间模型的定量描述的技术系统在产品开发中的属性。由于所需的重点是首先在气体和液体（牛顿）介质的假设下，缓慢变化的过程和层流条件下的工作空间。该模型应帮助产品开发人员评估不期望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一系列样本工作空间模型，另一方面为限制情况建立了一系列样本工作空间模型。此外，需要一个程序来对关键工艺功能和操作条件进行数学分析，该程序需要进行测试和验证。需要汇编关于将工作空间模型转换为虚拟开发工具的机会的信息，以便用增强的工作空间模型描述复杂的问题。

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.
