In the fusion design process of the system, ill-conditioned features, that are not explicit in previous generation systems, may exhibit to negate the operation of the new-generation system. This type of ill-conditioned feature is termed as the recessive ill-conditioned feature (R-ICF) of the system. It is believed that R-ICF in the fusion design process is attributed to the complex system recessive inheritance mechanism (C-RIM), which is analogical to organism recessive inheritance. In-depth study of the characteristics of C-RIM, it is found that one of the reasons leading to R-ICF is the recessive couplings between parameters of the previous generation of systems. This article proposes screening methods for recessive couplings and preliminary methods to intervene R-ICF. An auxiliary software is developed to facilitate implementation of the currently proposed methods. In order to reduce the number of design iterations due to R-ICF, thus to improve efficiency for the fusion innovation process, this article further proposes a system fusion innovation design process model based on C-RIM. Through this process model, R-ICF incurred by recessive couplings can be detected and resolved in advance at the early-stage of product design. The applicability of the currently proposed process model is demonstrated by design exemplification with an irregular workpiece transport system.

在系统的融合设计过程中，上一代系统中不明确的病态特征可能会表现出否定新一代系统的运行。这种类型的病态特征被称为系统的隐性病态特征（R-ICF）。融合设计过程中的R-ICF被认为是复杂系统隐性遗传机制（C-RIM）的结果，类似于生物体的隐性遗传。深入研究C-RIM的特点，发现导致R-ICF的原因之一是上一代系统参数之间的隐性耦合。本文提出了隐性耦合的筛选方法和干预R-ICF的初步方法。开发了辅助软件以促进当前提出的方法的实施。为了减少R-ICF带来的设计迭代次数，从而提高融合创新过程的效率，本文进一步提出了一种基于C-RIM的系统融合创新设计过程模型。通过该过程模型，可以在产品设计的早期阶段提前发现并解决隐性耦合引起的R-ICF。当前提出的过程模型的适用性通过不规则工件传输系统的设计实例得到证明。通过该过程模型，可以在产品设计的早期阶段提前发现并解决隐性耦合引起的R-ICF。当前提出的过程模型的适用性通过不规则工件传输系统的设计实例得到证明。通过该过程模型，可以在产品设计的早期阶段提前发现并解决隐性耦合引起的R-ICF。当前提出的过程模型的适用性通过不规则工件传输系统的设计实例得到证明。
