Laboratory is an important place of practice for teaching and scientific research in Colleges and universities. The design of experimental furniture plays a very important role in the design of indoor environment. Ergonomics takes man-machine-environment as its research object. By revealing the law of the relationship between man-machine-environment, it can optimize the performance of man-machine system and improve the living and working environment. From the angle of ergonomics, this paper discusses the design of laboratory furniture, that is, to make full use of ergonomics principles in the design of laboratory furniture, to meet the ergonomics needs of users as far as possible, and to make the experimenter feel convenient, comfortable and lightly pleasant when operating the experiment.
Ergonomics originated from Europe and America, also known as "ergonomics". The International Society of Human Engineering defines ergonomics as "the study of human anatomy, physiology, psychology and other factors in the working environment, the study of the interaction of various components of the system (efficiency, health, safety, comfort, etc.), and the study of how to achieve the optimization of human-machine-environment in the working and family environment and in the vacation environment". In the laboratory, the human environment system of the laboratory is composed of the experimenter, equipment, furniture and indoor environment. Ergonomics uses the methods of human physiology, psychometrics and measurement to study the factors of human structure, function, psychology and mechanics of laboratory operators, so as to meet the needs of people's physical and mental activities, and to achieve the best use efficiency.
2 Current problems in laboratory furniture design
At present, the furniture design of many laboratories does not meet the needs of the human body, which brings a lot of inconvenience to the experimental operation. For example: some experimental table table height is unreasonable, too high cause neck and shoulder discomfort, too low cause back forward. In some cases, the width of the desktop is not enough and the manipulation space of the arm is too small, resulting in fatigue and soreness of the muscles of the shoulder and elbow. Some experimental manipulators are unreasonable in space design, unclear division of experimental instruments and materials, and disorderly placement of instruments and equipment, which can easily lead to visual fatigue and misoperation. Some experimental chairs do not meet the needs of the human body, long-term sitting experiments are easy to backache.
To sum up, the design of experimental furniture should be people-oriented, fully apply the principles of ergonomics, respect the physiological and psychological needs of experimental operators, provide them with scientific, convenient, comfortable and pleasant experimental furniture, improve and optimize the internal environment of the laboratory, and then improve the accuracy and innovation rate of the experiment, so as to achieve better teaching and scientific research results.
