Design Of Food Pesticide Residues Detector Based On Portable Mode

With the popularization of modern health knowledge,fruits and vegetables have become the essential food for modern people to eat three meals a day.However,in China,except for a few green fruits and vegetables meeting certain quality standards,most fruits and vegetables are polluted by pesticides to varying degrees in the process of planting.The pesticide residues have a serious impact on people’s body and some harm.When the pesticide accumulated in human body reaches a certain extent,it will cause different degrees of damage to the body.Especially,the most serious injury to pregnant women is.The quality of modern life is getting better and better,and the awareness of the user group on the aspect of food health has become stronger and stronger.Especially,it is worth paying attention to that the pesticide residues in fruits and vegetables are too much,which leads to the food safety and the problems of residual agricultural drugs.Therefore,this paper has made innovations in the product design of household agricultural residue detection to meet the needs of users.According to the principle of ergonomics,a portable and safe detector machine for home users is designed based on food.The purpose is to make its structure more reasonable,function more applicable,operation mode more humanized and appearance more beautiful.Thus,it shows the first and second function characteristics in the same kind of products,and forms the leading competitiveness.Secondly,discuss the theory and principle of the function design of the detector,describe the design principle of the function and confirm the design strategy,such as:simple operation principle,product touch interaction principle,functional aesthetics principle.Then,the design direction and parameters are determined according to the research of hand muscle distribution and grip curve in the interaction design practice and research,and the extraction strategy of detector appearance modeling intention.Finally,on the basis of the confirmed research parameters,the work of product design is started.This topic has confirmed the unity of product appearance,product engineering structure and product function before design,and then went through the process of modeling image conception,sketch design,scheme evaluation and screening,combined with the needs of consumers,completed the design.The practice process of the project runs through the design concept of agile and easy operation,comfortable operation touch,personalized fashion aesthetic principles,explores the user’s behavioral needs and aesthetic demands,integrates the use value,aesthetic value and emotional value of the product,so as to enhance the added value of the product.
