Technical Field

The utility model relates to a pen tool, in particular to a portable pen for product design.

Background

Product design is a series of technical works from the creation of a new product design task book to the design of a product sample. The work content is to set up the project requirements (including the performance, structure, specification, type, material, internal and external quality, service life, reliability, service condition, technical and economic index, etc.) in the product design task book and the implementation design task book. The product design should do: (1) the designed product is advanced and high in quality and can meet the use requirements of users. (2) The manufacturer and the user of the product can obtain better economic benefit. (3) From the practical point of view, the optimum design is made with full attention to the resource conditions and the production and living standards. (4) Attention is paid to improving the serialization, generalization and standardization level of the product. The main categories are: a new product is designed by itself; surveying and mapping imitation of external sample objects; designing an external drawing; improved design of old products. The method has the advantages that the design and drawing of products are extremely important links, such as rudimental sketches of the products, many products are generated due to one-time inspiration, the best mode for recording the inspiration is to draw the sketches of the products, the existing drawing board and painting brush is large in size, not suitable for carrying, and lack of a pen tool suitable for recording the sketches at any time.
