基于GQFD的手持工具人机工程设计研究

Research on Ergonomic Design of Hand-held Tools based on GQFD

为优化手持工具的用户使用体验,提出一种将基于灰色关联分析的质量功能展开(GQFD)与人机工程相结合的设计方法,并将其应用于手持工具的产品研发中。首先采用非参与式观察法观察用户行为并获取用户需求,并依据手持工具的人机工程设计原则将用户需求转化为对应的设计要素;再运用GQFD构建设计质量屋,对用户需求与设计要素的相关关系度进行量化评价,分析设计要素重要度,从而明确重点设计目标;最后根据人机工程学的原理和方法,对重点设计目标进行分析设计,得到最终的设计方案。将该方法应用于德国Prym公司的手工钳改良设计项目,设计结果不仅满足了用户使用需求,而且提升了用户体验,为手持工具类产品的创新设计提供一种新的研究思路。

In order to optimize the user experience of hand-held tools,the combination of quality function deployment based on grey relational analysis(GQFD)and ergonomics is applied to the product development of hand-held tools.Firstly,use non-participatory observation methods to observe user behavior and obtain user needs,and according to the ergonomic design principles of hand-held tools,the user needs are transformed into corresponding design elements;then use GQFD to construct a house of design quality,quantitatively evaluate the correlation between user needs and design elements,analyze the importance of design elements,so as to clarify the key design goals;finally,according to the principles and methods of ergonomics,the key design objectives are analyzed and designed,and the final design scheme is obtained.This method is applied to the improvement design project of manual plier of Prym Company in Germany.The design result not only meets the needs of users,but also improves the user experience,providing a new research idea for the innovative design of handheld tool products.
