Description

Portable device contoller for bicycle riding

The present invention relates to a wireless wireless remote control for a bicycle, and more particularly, to a control device capable of controlling music and calls by reflecting an ergonomic factor in order to prevent distraction and accidents caused by a mobile device operation while driving.

Recently, the number of people using bicycles for eco-friendly trends and leisure and hobbies is increasing. However, the increase in bicycle accident rate is also shown in the trend of bicycle accident incidence between 1998 and 2009 of the National Statistical Office shown in FIG. The increase in the number of people using bicycles may be a big factor, but the activities such as listening to music or making phone calls with mobile devices used on bicycles can reduce the attention and increase the accident rate.

First, a survey of 99 bicycle users is conducted to derive the feasibility and improvement of the design.

1 is a questionnaire.

Figure 2 is the sex ratio of the questionnaire, men and women were evenly investigated.

Figure 3 shows that the purpose of the bicycle use of the survey results, leisure use occupies a large proportion.

Figure 4 is a survey of the ride time of the bike was the number of people riding less than 30 minutes.

5 shows that most people enjoy music when riding bicycles as a preference for listening to music when using bicycles.

FIG. 6 shows that most people feel difficulty in using a mobile device when using a bicycle due to inconvenience of using a mobile device when using a bicycle.

Figure 7 shows the correlation coefficient of the questionnaire content, and measured the correlation coefficient whether there is no discomfort when listening to music when using the bicycle and when operating a mobile device when using the bicycle. The correlation between the above two items is large because the correlation coefficient R = 0.73 is found and it is statistically significant.

8 is a reliability test of the questionnaire, and the reliability test was performed using a statistical program to test whether the questionnaire is reliable. The questionnaire is credible because of the statistically significant cronbach's coefficient of 0.844.

As a result of the survey, bicycle users were mostly in their twenties, and they enjoyed using bicycles and using mobile devices such as music and smartphones. However, a reliable survey showed that there was a lack of operability and a safety risk when riding a bicycle.

When using a bicycle, it provides operability for those who enjoy music or mobile device operation and at the same time prevents the possibility of an accident that may occur due to the operation of the mobile device. In general, the device was designed to complement the user's cognition and attention, and to give a comfortable feeling in consideration of the user's human characteristics.

In order to solve the above problems, according to the embodiment of the product consists of three parts, the fixing part of the lower part to be fixed to the handlebar frame of the bicycle, the control part on the top of the product, and to configure the control part There is a button part.

The operation part has universality of design and operation based on Korean standard hand measurement data (http://sizekorea.kats.go.kr/).

In terms of functions, users can listen to music and use the call function mainly for volume control, playback, and turn up the next song.

 According to the present invention as described above has the following effects.

First, the bicycle occupant can easily control the operation state of the mobile device without a separate large operation.

Secondly, it is possible to control the mobile device through an operation that does not distract attention, so that the bicycle can be driven more safely.

Third, the product can be easily and quickly removed by a suitable fixing method.

Fourth, anyone can use the product comfortably by designing the product according to Korean standard hand data.

Fifth, it is a design that anyone can feel the convenience of operation by adopting the interface with the least muscle usage.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can be specifically realized the object of the present invention. In describing the present embodiment, the same designations and the same reference numerals are used for the same components, and further description thereof will be omitted.

According to the result of FIG. 1, it was found through the reliability verification of FIG. 8 that the bicycle user enjoys using the mobile device while riding the bicycle based on the correlation coefficient of FIG.

According to the necessity of this problem, we will design a product design that can solve the problem.

Before deciding on the design of the product to be designed, the material is decided first.

The products of the polyurethane material of Figure 9 are excellent in mechanical strength, abrasion resistance, impact resistance and the like and have a strong weather resistance, oxidation resistance is adopted as a material of the product in terms of good resistance to the external environment and human-friendly.

In addition, prior to fixing and using the product, there must be no movement when using the bicycle, and a choice of a method for a user concerned about theft of the device is required. And considering the production price of the product, we compare and select three fixed methods that do not have a high unit price.

Figure 10 is a bangle form commonly seen in women's accessories. This way

It fits on a bicycle and has the advantage of being easily removable.

11 is a cable tie for organizing cables, the length of which can be increased or shortened. There is an advantage that the adjustment of the length is easy.

Figure 12 has the advantage that the length is very easy to adjust the removable Velcro tape.

After comparing the methods, we decided to adopt the bangle type method. In the case of the cable tie method, since the diameter of the bicycle bar does not show a big difference between bicycles, the maximum advantage is that it is not easy to adjust the length. In the case of the Velcro tape method of Figure 12 is inappropriate due to the characteristics of the bicycle used outdoors. For this reason, the bangle method of FIG. 10 is adopted, which is easily detachable and has an advantage in design.

Next, we set the default size of the product using Korean standard hand data.

Figure 13 is the data for the thumb length from 20 to 80 adults.

Set the product size based on the average 58.7mm.

FIG. 14 shows data on the thumb open range from 20 to 80 years of age, and the product size is set based on an open angle of 33.5 degrees, which is an average value of 1st quartile, in order to satisfy the range of use of all users.

Based on the illustration of FIG. 13 and FIG. 14, a standard size of a product available to all 20-80 year olds is set.

The distance that the thumb of the average length 58.7mm can be moved using the calculation formula of FIG. The linear length of the drive unit applying the distance is 34.321 mm.

The prototype set based on the illustration of FIGS. 13, 14, and 41 is as shown in FIG. 16 and sets the straight length to 36 mm in order to give a design clearance to the driving unit.

17 is a survey example of an operation function for setting an interface of a user. Based on the tact switch, wheel switch, and jog switch in the contents, prototypes of one to three eyes are set up.

The prototype shown in FIG. 18 consists of three tact switches and the contents of FIG. The user interface is as shown in FIG. The design, which is attached to the handlebar frame of the bicycle, can be used symmetrically, and it is intended to be operated naturally by making a curved shape following the most comfortable shape when the hands are in a dormant state.

The prototype shown in FIG. 19 is constructed based on one jog dial and the contents of FIG. The user interface is as shown in FIG. 22. This design, which is attached to the bicycle handlebar frame, allows intuitive operation, but there is a risk of malfunction if there is a slight direction error in the direction of operation.

The prototype shown in FIG. 20 was constructed based on one wheel dial, one tact switch, and the contents of FIG. 16. The user interface is as shown in FIG. Attached to the bike handlebar frame, the design is symmetrical and can be quickly controlled with wheels for good operability.

Next, when using the three prototypes shown in Figs. 18, 19, 20, the EMG measurement test to determine which muscle fatigue degree is the smallest.

Electromyography is an examination of the electrophysiological phenomena of nerves and muscles using a machine to objectively measure muscle fatigue.

The experiment was conducted at the Hanyang University Ergonomics Laboratory, and 4 subjects. Each experimenter uses three prototypes to measure muscle usage and compares how much the usage increases with a dormant state (without muscle).

Measurement muscles are the long hair flexors of FIG. 24 and the short hair extensor muscles of FIG.

Prior to the experiment, the three prototypes of the test subjects were sequentially measured in order to reduce the error by performing the experiment in the order of FIG. 42 in consideration of accumulated muscle fatigue accumulation. Prototype 1 is as shown in FIG. 18 and prototype 2 is as shown in FIG. Prototype 3 is as shown in FIG. 20.

An example for attaching the EMG measuring device before proceeding with the experiment is shown in FIG. 26.

Channel 1 is connected to the abdominal extensor muscle of FIG. 24, and channel 2 is attached to the long hair flexor muscle of FIG.

28, 29, and 30 are results of measuring changes in muscle usage when using three functions (playback, skipping, and sound volume control). Channel 1 represents the muscle usage of the extra-terminal extensor muscles shown in FIG. 24 and channel 2 represents the muscle consumption of the long limb muscles shown in FIG. The equation shown in FIG. 27 calculates the amount of change in the dormant state. The amount of change in the dormant state is divided by the amount of change in the dormant state because both the dormant muscle usage and the magnitude of the force of each test subject are different.

As a result of comparing the measured amounts, the muscle usage was the highest when three eyes were used, and the one eye used the least muscle on the basis of the results of FIGS. 31, 32 and 33. To analyze this in more detail, a hypothesis test was performed using the statistical analysis tool ezSPC. Since the samples alone do not show a significant difference, the confidence intervals of the sample mean were measured and the hypothesis test was used to determine whether the usage differed significantly. 34, 35, and 36, the confidence interval was 90%, and the test results showed a significant difference when using the play button and the skip button. This confirmed that the muscle usage in one eye was the lowest.

As a result of EMG measurement, a basic design and an interface of three tact switches shown in FIG. 18 were adopted.

Next, in order to determine the size of each switch, the thumb effective area of 21 adult men and women was measured.

As shown in the example shown in Figure 40, each of the measurers wrapped the 250ml canned beverage, buried the paint on the thumb portion and showed the effective portion on the paper by pressing the switch operation.

Finally, collect the 21 size samples of the switch used to operate the switch through the paint.

The average size of the thumb portion for manipulating the adult switch shown through the method of Figure 40 is set to a size of 13mm horizontal, 13mm vertical.

37 is a front view of the finally derived design.

Designed to fit inside diameter of 25.4mm which is used most frequently in handlebar frame.

The operation unit finally derived is as shown in FIG.

The vertical length of the entire control panel was designed to be 37.4 mm based on FIG. 13 and FIG. The most common play and call buttons are designed to be 13mm wide by 13mm wide.

The perspective view of the finally derived design is as shown in FIG. 39.

The operation unit 10 of the main body consists of three tact switches.

The transceiver 20 of the main body is more protruding than the switch.

The fixing part 30 of the main body serves to fix the main body to the bicycle as a fixing body using the elasticity of the polyurethane material.
