Abstract Hand drill is commonly used in our daily life. But it has many unreasonable factors especially in security aspects. Unreasonable designed hand drill will do harm to users .This article, stands in the point of design psychology to analysis the security psychology of hand drill. Through the analysis of a new hand drill to expound its security design from the appearance design and usage security two aspects .

Hand drill is the best seller in the electric tool industry which is widely used in architecture, decoration, furniture etc to punch or make a hole in an object . Hand drill can be classified as household type and professional type. Household hand drills call for a lower demand in service life 、work efficiency 、work accuracy .It is under mass production ,accounts for about 70~80 percent of electric products. The other 20~30 percent are professional type, this type has a higher demand over household ones in work accuracy、work reliability、service life and performance etc. As a directly contact tool with people ,the security problem should be fully considered.

There are various kinds of hand drills on the market ,but many of them are unreasonable designed. Hand drills vibrate in use , users may easily get tired with no auxiliary handle, only one handle to support ; spinning drill not only brings panic to users but also gives scraps which may hurt them ; the drill is hard to locate; hand drill brings noise pollution; cold mechanical shape design makes people feel uneasy. And some details may also cause troubles . (Fig.1. shortcomings of hand drill) .Consequently, hand drill design should consider its use security in various aspects. [1]
2 .The security analysis of hand drill Hand drill have a high operating frequency in daily life. Unreasonable design may cause many upper limbs occupational disease or even systemic harm. Thus, hand drill design should follow the ergonomic principles and start with human’s security psychology. 2.1 hand drill appearance design exploration 2.1.1 hand drill’s shape exploration Function decides form, especially in some practical product like hand drill, no matter its entirety or details , should satisfy people’s need and give users a better operation. See from a integral hand drill, it should be streamlined and not too heavy. Pointed shapes may seem aggressive while streamlined form looks moderate; overloaded hand drill increase fatigue,so it should be less than 0.45kg. In details, proportionate relationship between hand and drill and ancillary distribution will directly influence operate. The length of hand drill should be less than arm length; the handle should not have groove; switch and other operating buttons should within fingers’ reach etc. [2] 2.1.2 Hand drill color design

Modern hand drill color design should make users feel stable and safe and even can improve work efficiency. Cold color give people a sense of mechanical cold while warm color may dispel that cold and feel light and soft. Hand drill color design should balance out between those two types of colors . [3] Fig.2. shows the development of hand drill color design, from traditional gray department to modern warm color. It also shows two fashion trends of hand drill color design nowdays. The first one is color warming trend , partly use yellow、orange 、red etc. The second is double toning or much toning. Double toning have a wide adaptability that can satisfy people in different ages、gender and professions. 2.2 New hand drill design analysis A series of research have been done based on the analysis of hand drill’s shortcoming and appearance design above. then find a new type of hand drill. 2.2.1 Analysis of a new hand drill appearance design As it shown in fig.3. The hand drill is similar to a hair dryer. Hand drills have been access to more families that its exterior design should have a more approachable shape to gain consumers’ interest. Hair dryer is a live electrical appliance that almost every family have, so the hair dryer shape hand drill becomes closer to people’s live. Overall streamlined without losing hale. Look from color design, the hand drill adopt double toning that can meet different groups of preferences. Overall uses white which belongs to neuter color, can break machinery of icy cold and give users a feeling of firmness . Local match with warm color to broke formalist of large color piece and increase the aesthetic. [4] 2.2.2 The analysis of new hand drill’s agreeableness There should be a protective barrier between drillbit and user from security point. The barrier can covers the drillbit to protect users from mistakenly touch and clastic splash ; the barrier can not affect the normal operation , that is the operator should be able to see how the drillbit works. A hand drill gives about 100 db noise which is much higher than urban environmental noise severe pollution standards (>74 db ). So the barrier can also appropriately consider the requirement of noise reducing. [5] Shown in fig.4 , a transparent barrier setted around the drill. The barrier is light and small so that it wouldn’t affect its total mass. The barrier have various functions. The first one is the transparent material can let users see how drillbit works clearly; the second is that the barrier’s cross section is parallel to the wall so that the drillbit can perpendicular to the wall in use and also have some positioning function.

third one is the barrier contract with the depth of drillbit , will not affect the operation. The forth is it can isolate some noise. [6] 2.2.3 Tactile analysis of new hand drill As a directly contact tool with people, whether the handle is reasonable designed or not is really important. The hand drill requires hard effort and accurate drilling, bear the focus on positioning and accurate positioning two properties. While the movement should not have both positioning property, the handle design is supposed to consider the feasibility and rationality of the operation to reduce the working intensity and difficulty. [7] From the focus on positioning terms, the handle should adopt hand joint curve for gripping comfortably and alleviating vibration ; handle should use the material which can increase friction; add some auxiliary handle to reduce finger stress. As it shown in fig.5, the auxiliary handle is different from traditional ones , behind or beside the handle. It’s a small change in the handle : extra A point. A gives hand an inward force while B gives an outward one . Those two forces put handle firmly fixed in the palms. [8] This handle design also spares extra auxiliary handle to save material and processing cost. 3 Conclusion Through the analysis of hand drill’s safety psychological above, combining ergonomics theory to discuss hand drill design in appearance safety、agreeableness etc. The analysis of a new hand drill is to help designer work out more reasonable hand drill and provide consumer with real safe hand drill and give people more convenience .
