Abstract

We will use SolidWorks to draw the model of the disposable lighter and inquire about the process and material of the relevant parts, and discuss its design concept, the material strength and functionality of each component, and cooperate with COMSOL to analyze the difference between theoretical and practical application to parts, reconsider what design tweaks or processing the component could have done to extend its life. Finally, we analyze the advantages and disadvantages of disposable lighters and our evaluation of this product, and also propose some feasible improvement plans for the shortcomings. That is, this project will describe the material, process, size, and function of each component of the lighter, and then explain the ignition and transmission principle of the lighter, and then discuss the use of the disposable lighter in different weather and operating environments, as well as the advantages and disadvantages of the processing process. Disadvantages, put forward feasible improvement methods for the shortcomings, and think about the design scheme that can make the disposable lighter more complete.
