Development and design of cordless electric drill control board

With the improvement of people's living standards and aesthetic awareness, consumers pay more and more attention to their own creation and artistic pursuit. Power tools designed for home users gradually enter our daily life and become an indispensable part of life. a member. Once any industrial tool enters the home, it must be endowed with a new appearance and function. Many household electric tools continue to introduce styling designs to improve the operability and safety of the product to meet the psychological and physical consumption needs of home users. 

Entering the Internet and information age, the intelligence and automation of product design began to enter people's lives. Intelligent design simplifies the operation of some professional tools, and the operation can be completed smoothly without professional knowledge, making it easier for ordinary users to use. The smart home rechargeable electric drill design in this article can enable consumers to control the electric drill through the interface like operating a smartphone, and can adjust part of the curve of the electric drill handle more intuitively and conveniently, making the handle more suitable for the user's palm and increasing the comfort of operation sex. At the same time, the rechargeable type used can be applied to various working environments, freeing you from the trouble of finding a power source.

1. Analysis of existing electric drill products

Generally speaking, the largest users of electric drills are young and middle-aged men who use them as tools, so most of the existing electric drill products on the market are designed for male users. In modern families, many women, the elderly, and even some disabled people have also joined the group of users of electric tools, which shows that the group of users of electric tools has undergone major changes. But now women and teenagers have smaller palms and handles with larger diameters lead to insufficient grip strength, which makes it difficult to use them.

2. Analysis of human-machine factors of portable electric drill

The products under research are aimed at ordinary home users, so the hand size measurement is carried out for users over 13 years old. According to the measurement results, the switch of the final electric drill product is set to the specification of two and a half fingers, that is, the height is 32.4mm. The experiment proves that, in this way It is more labor-saving and safer to use. The design of the handle part adopts an organic shape with an elliptical cross-section to facilitate the user's grip. At the same time, according to the suggestion in "Ergonomic Principles in Hand Tool Design": handles with different structural forms have different optimal handle spans. The pistol handle is generally 5~6cm, and the straight handle is 4.06~6.10cm. For the diameter of the handle in the design of the electric drill, the majority of electric drill users have put forward a clear requirement: they hope that the diameter is smaller. Therefore, this topic adopts a smaller handle diameter when designing the handle diameter. Such a tool is light in weight and easy to hold. Under normal circumstances, the handle of an electric manual electric drill is close to the size of a straight handle or a pistol handle. When designing, it is advisable to consider a width of 4~6cm and a diameter of 2.5~4cm.

3. Design example of rechargeable portable electric drill

The products studied in the project are aimed at ordinary household users. The characteristic of this group of people is that they have no corresponding professional knowledge of electric drills, and there are many uncertain factors for electric drill products. Therefore, the ease of operation of the products must be fully considered to ensure that users without experience can also Can complete various operations easily and freely. At the same time, combined with the man-machine size of the palm of the home user and the needs of related users, the conception of the scheme was carried out on the basis of market research, and the appearance design direction of the smart home rechargeable electric drill based on ergonomics was finally determined:

3.1 The main design of the electric drill

①The overall shape chooses a streamlined design style based on organic curves to reduce the visual weight brought by the product. The aiming axis is full of volume and reflects the sense of strength; the line of the handle is smooth and concise with the palm curve as a reference;

② Add water column to test and ensure whether the electric drill is kept in a horizontal state;

③After repeated experiments and tests, the switch button of the electric drill is made into a two-and-a-half-finger specification, which is more labor-saving and safer to use;

④ The material is made of soft and hard rubber to increase the comfort of the hand and ensure non-slip;

⑤ There are two fashion trends in the design color of electric drills. One is the overall color warming trend. Warm colors have the characteristics of eye-catching, strong affinity, and advancement. Black, blue-black, green-black, yellow-black, etc., that is, one bright color and one achromatic color (black and white), such a combination can better use color to partition products and remind consumers of important information. Therefore, this standard collocation is still used in this project.

3.2 Adjustable handle design

The market target of this electric drill is household type, which determines that the main users of this product have problems such as a large age span, large differences in physiological and psychological factors, and a large gap in knowledge structure. Based on the analysis of the difference in palm size between men and women in different age groups, this project creatively uses Shape Memory Alloys (SMA) in the rubberized part of the electric drill handle. After heating, SMA can completely eliminate its deformation at lower temperature and restore its original shape before deformation. The user can click the operation interface at the tail of the electric drill to select the part to be adjusted, and control and change the convexity of the rubberized part through temperature rise and fall, so as to increase the degree of friction to adapt to different sizes of hands. The soft pad at the back of the drill body can help the user reduce the impact force when the electric drill is working, and at the same time play a role in protecting the operation interface.

3.3 Design of charging base for electric drill

The base adopts silver as the main color, blue as the auxiliary color, matched with the blue and black color of the main body of the electric drill, while enhancing the overall sense, it also divides the main body of the product and the charging base by color; in terms of the shape design of the base, refer to The shape of the existing products on the market is simplified, and the visual weight is reduced by simplifying the lines of the base, and the curve is integrated to make the overall design more harmonious; a frame is added around the base to increase the stability of the base, and the shape is more novel; heat dissipation adopts The fan blade method can discharge the waste heat generated during charging to the greatest extent, which is beneficial to prolong the service life of the base and the battery.

Summarize

When electric tools enter the daily life of consumers, what needs to be changed is not only the shape, color and other appearance factors, but also the ease of operation of the product needs to be improved and upgraded in combination with existing technologies, simplifying the complexity, and adopting a more concise and intuitive way Transform professional operations so that more ordinary consumers can use them. In recent years, with the rapid development of science and technology in our country, the emergence of various new materials and new technologies has injected new energy into product design. The development of Internet technology has made more and more intelligent products appear in people's daily life. Intelligent products have creatively integrated science and technology with consumer needs. In the future, the development and innovation of electric tools in my country will not only need to strengthen and improve product functions, but also have a product design that can reflect the characteristics of the times.
