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.

集成AD和TRIZ的箱式电梯防疫功能创新设计
箱式电梯狭小空间内人员之间大量的间接接触给2019冠状病毒病的传播带来了隐患，如何抑制病毒在电梯中生存和传播成为亟待解决的问题。为此，通过分析公理化设计（axiomatic design，AD）和发明问题解决理论（Teoriya Resheniya Izobreatatelskikh Zadatch，TRIZ）这2种创新设计方法的优缺点，面向突破性设计、适应性设计和变参数设计等不同的设计类型，提出了集成AD和TRIZ的创新设计方法。首先，对产品的功能需求进行分析，以确定其归属的设计类型，并利用AD理论对功能需求进行分解，采用TRIZ构建功能-结构树。然后，对初步确定的设计方案进行耦合判断，并利用TRIZ进行解耦，经多次迭代求解后得到最终的设计方案。以传统箱式电梯的公共交互控制面板和密闭运载轿厢为研究对象，面向阻止病毒传播和消杀病毒的功能需求，采用集成AD和TRIZ的创新设计方法对箱式电梯的防疫功能模块进行设计，最终为传统箱式电梯设计了非接触式交互控制模块和分条件消毒灭菌模块。创新设计实例在从传统的机械结构设计拓展到新型的人机交互模式设计方面做了有益的尝试，验证了集成AD和TRIZ的创新设计方法的可行性。研究结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撑。
