【摘要】：为进一步缓解全球气候变暖,从源头降低产品生命周期碳排放的低碳设计日益成为产品设计的重要方向。基于对产品低碳设计过程中决策信息的构成及对应设计策略的研究,构建了一种融合碳足迹的产品低碳设计信息模型,并在分析低碳设计决策信息内涵的基础上提出了一种基于产品结构树和详细设计参数的双重递进碳足迹根源特征定位方法。该方法基于定性/半定量矩阵的简约式生命周期评估(streamlined life cycle assessment,SLCA)法对碳排放关键结构单元进行初筛,并采用赋权关联图方法定位低碳设计的关键特征和设计参数。针对设计参数矛盾,利用TRIZ冲突解决理论进行求解从而实现低碳设计目标。以手持吸尘器作为低碳创新设计案例,对所提方法的可行性和有效性进行了验证。
[Abstract]:In order to further mitigate global warming, low carbon design, which can reduce carbon emission from source, has become an important direction of product design. Based on the research on the composition of decision information and the corresponding design strategy in the process of low carbon product design, a low carbon design information model of product with carbon footprint is constructed. On the basis of analyzing the connotation of decision information of low carbon design, a dual progressive carbon footprint feature localization method based on product structure tree and detailed design parameters is proposed. This method is based on qualitative / semi-quantitative matrix reduced life cycle assessment (streamlined life cycle assessment SLCA) method to screen the key structural units of carbon emissions, and uses weighted correlation graph to locate the key features and design parameters of low-carbon design. Aiming at the contradiction of design parameters, the TRIZ conflict resolution theory is used to solve the problem to achieve the low carbon design goal. The feasibility and effectiveness of the proposed method are verified by using the hand-held vacuum cleaner as a low carbon innovative design case.
