本文运用逻辑和系统工程观点,从思维和行为两个方面研讨有关设计方法的主题。 文中阐明,一个正确的设计方法,必须遵照从抽象到具体、从发散到收敛、从核心到整体的逻辑思维过程。这是使设计人员的创造能力得以充分发挥的唯一途径。 设计用的系统方法是系统工程在设计中的具体应用,其核心是用系统观点依据能量流、材料流以及信号流的转换,在功能、物理和结构等方面揭示机械系统内部的固有联系,以及一切机械系统的共同本质。当方案设计采用此方法时,将会为达到最佳方案开辟宽广的通道。
This article uses the logic and systems engineering point of view, from two aspects of thinking and behavior to discuss the theme of the design method. The article states that a correct design method must follow the logical thinking process from abstract to concrete, from divergence to convergence, and from the core to the whole. This is the only way to give full play to the creative ability of designers. The systematic approach to design is a concrete application of system engineering in design. Its core is to reveal the inherent relationship within the mechanical system in terms of function, physics and structure based on the system view based on the conversion of energy flow, material flow and signal flow, and The common essence of all mechanical systems. When this approach is adopted in a program design, there will be a broad avenue for achieving the best solution.
