Guided by a technological revolution, widely discussed paradigms as servitization and Circular Economy (CE) are progressively pushing manufacturers towards delivering increasingly complex solutions. Design plays a strategic role in this sense, either considering products, services or Product-Service Systems (PSSs). Concurrent engineering and, specifically, Design for X (DfX) approaches have been widely associated to products, revealing great potentialities for enhancing service functionalities like supportability and circularity. Again, DfX approaches have been already exploited to systematically support the PSS design process, given their re-known ability to allow a better information sharing between product designers and service managers. However, even if several DfX approaches related with the End of Life (EoL) stage already exist (e.g. Design for recycling, remanufacturing and EoL), they still need to better fit with a circular design perspective. Therefore, the aim of this paper is exploring and understanding how design can contribute towards a CE transition through the adoption of DfX approaches.

在技​​术革命的引导下，广泛讨论的服务化和循环经济（CE）范式正逐步推动制造商提供日益复杂的解决方案。在这种意义上，设计在考虑产品，服务或产品服务系统（PSS）方面起着战略性作用。并行工程，尤其是Design for X（DfX）方法已与产品广泛关联，显示出增强服务功能（如可支持性和循环性）的巨大潜力。再次，DfX方法已经被利用来系统地支持PSS设计过程，因为它们具有重新定义的功能，可以在产品设计师和服务经理之间更好地共享信息。但是，即使已经存在几种与寿命终止（EoL）阶段有关的DfX方法（例如 对于回收，再制造和EoL的设计，他们仍然需要更好地适应圆形设计的观点。因此，本文的目的是探索和理解设计如何通过采用DfX方法为CE过渡做出贡献。
