Abstract

The large number of indirect contact between people in the narrow space of the box elevator has brought hidden dangers to the spread of COVID-19 (Corona Virus Disease 2019). How to inhibit the survival and spread of the virus in the elevator has become an urgent problem to be solved. Therefore, by analyzing the advantages and disadvantages of axiomatic design (AD) and Tteoriya Resheniya Izoblateskikh Zadatch (TRIZ), an innovative design method integrating AD and TRIZ was proposed for different design types, such as breakthrough design, adaptive design and variable parameter design. Firstly, the function requirements of the product were analyzed to determine its design type, and the function requirements was decomposed by the AD theory, and the function-structure tree was constructed by the TRIZ. Then, the coupling judgment of the initial design scheme was carried out, and the TRIZ was used to decouple. After several iterations, the final design scheme was obtained. Taking the public interactive control panel and the enclosed car of the traditional box elevator as the research object, facing the function requirements of preventing virus transmission and eliminating virus, the innovative design method integrating AD and TRIZ was adopted to design the epidemic prevention function module of the box elevator, and the non-public contact interactive control module and the conditional disinfection and sterilization module for the traditional box elevator were designed. The innovative design example made a beneficial attempt to expand from the traditional mechanical structure design to the new human-computer interaction mode design, which verified the feasibility of the innovative design method integrating AD and TRIZ. The research results can provide effective theoretical support for the conceptual innovative design of new functional modules of products. © 2021. All Rights Reserved.

集AD与TRIZ于一体的箱式电梯防疫功能创新设计

箱式电梯狭小空间内大量人员间接接触，为新冠病毒传播带来隐患。如何抑制病毒在电梯内的生存和传播，已成为一个亟待解决的问题。因此，通过分析公理化设计(AD)和TRIZ (Tteoriya Resheniya Izoblateskikh Zadatch)的优缺点，针对突破性设计、自适应设计和变参数设计等不同的设计类型，提出了一种将AD和TRIZ相结合的创新设计方法。首先对产品的功能需求进行分析，确定其设计类型，利用AD理论对功能需求进行分解，利用TRIZ构造功能结构树;然后对初始设计方案进行耦合判断，并利用TRIZ进行解耦。经过多次迭代，得到了最终的设计方案。以传统箱式电梯的公共交互控制面板和封闭轿厢为研究对象，面对防止病毒传播和消除病毒的功能需求，采用AD与TRIZ相结合的创新设计方法，设计了箱式电梯的防疫功能模块;设计了传统箱式电梯非公共接触交互控制模块和条件消毒灭菌模块。创新设计实例为从传统的机械结构设计向新型人机交互模式设计拓展做了有益的尝试，验证了AD与TRIZ相结合的创新设计方法的可行性。研究成果可为产品新功能模块的概念创新设计提供有效的理论支持。©2021。版权所有。

期刊介绍： Chinese Journal of Engineering Design is a reputable journal published by Zhejiang University Press Co., Ltd. It was founded in December, 1994 as the first internationally cooperative journal in the area of engineering design research. Administrated by the Ministry of Education of China, it is sponsored by both Zhejiang University and Chinese Society of Mechanical Engineering. Zhejiang University Press Co., Ltd. is fully responsible for its bimonthly domestic and oversea publication. Its page is in A4 size. This journal is devoted to reporting most up-to-date achievements of engineering design researches and therefore, to promote the communications of academic researches and their applications to industry. Achievments of great creativity and practicablity are extraordinarily desirable. Aiming at supplying designers, developers and researchers of diversified technical artifacts with valuable references, its content covers all aspects of design theory and methodology, as well as its enabling environment, for instance, creative design, concurrent design, conceptual design, intelligent design, web-based design, reverse engineering design, industrial design, design optimization, tribology, design by biological analogy, virtual reality in design, structural analysis and design, design knowledge representation, design knowledge management, design decision-making systems, etc.
