The scrap rate of hardware power tools can reduce the generation of electronic waste. In the past few years, the amount of electronic waste in the world has increased dramatically, accounting for 5% of the world's municipal solid waste, which is almost equal to the sum of all plastic packaging materials. Electronic waste is more harmful to the human body. It is not only developed countries that produce electronic waste. Developing Asian countries also discard nearly 120 million tons of electronic waste every year. In the classification of garbage, scrapped power tools are a type of electronic waste. To reduce the output of garbage, according to the 3R principle of sustainable design, it is necessary to reduce the waste of resources, improve the utilization rate, and increase the number of recyclable parts.
With the advent of the intelligent era of power tools, the structure of its electronic components will become more complex. Do a good job of functional division, modularization will be the mainstream, and energy innovation of power tools is also a future development trend. The development of new energy and energy storage technology will have an important impact on the development of power tools, and power tools will enter a new era.
Safety is an issue that must be considered in the design process of handheld power tools. The design for this issue can not only solve the safety problem in use, but also achieve harmonious coordination between people, objects and the environment.
