摘要
为提高创新设计的效率和改善产品的生态性能,提出一种面向产品创新及生态性改进的设计方法。该方法以发明问题解决理论(Theory of inventive problem solving,TRIZ)的对标分析、功能导向搜索和特征传递等现代工具为基础,对产品进行创新设计,快速构建多个初步方案。根据TRIZ的48个工程参数,建立工程参数与生态设计效率参数的关联表,提出了利用该关联表和TRIZ冲突分析工具对初步方案进行生态性改进的措施。基于TRIZ理想度概念,提出综合运用功能性理想度和生态性理想度对系统方案进行评价的新方法,评估设计方案的理想度。根据这些方法,构建了流程化的产品创新及生态性改进设计过程模型。将该模型应用于设计示例,快速得到一系列初步方案及生态性改进方案,并方便有效地对不同方案进行定量评估,实现方案优选,从而验证了该设计方法提高创新效率及改善生态性能的明显效果。
To improve the efficiency of innovative design and the ecological performance of product, an innovative and ecological design method is presented for product development. Based on some TRIZ tools like benchmarking, function oriented search, feature transfer, a new approach to concept innovative design of product is put forward to build a few preliminary schemes rapidly. In order to improve the ecological performance of product, the correlate table of engineering parameters and eco-efficiency parameters is structured according to 48 engineering parameters of TRIZ. By making use of the table and the contradiction analysis tool of TRIZ, the process of ecological improvement to preliminary schemes is constructed. Based on the degree of ideality in TRIZ, an evaluation method used for assessment on design schemes is proposed by synthesizing the degree of functional ideality and the degree of ecological ideality. According to these study, a sequential process model of innovative and ecological design method is built for product development. When the process model is applied to the case of garbage collection device design, lots of preliminary and ecological improvement schemes are acquired quickly. At last, the different design schemes are quantitatively assessed by using the evaluation method. The example have proven the effectiveness of the innovative and ecological design method.
