1 is a perspective view showing a time management device according to an embodiment of the present invention. FIG. 2 is a perspective view illustrating the time management apparatus according to FIG. 1 from a different angle. 3 is a schematic diagram schematically showing a control configuration of the time management apparatus according to FIG. 1.

As shown in FIGS. 1 to 3, the time management apparatus 10 according to an embodiment of the present invention has a cube shape, and is a device capable of displaying time on a plurality of surfaces and counting (count up/down). . The time management device 10 may be linked with an application (hereinafter referred to as “app”) installed on a user device such as a smart phone so as to store and manage the counted details.

On (ON) / off (OFF) of the time management device 10 may be performed by a power button not shown in the drawing. When the power button is operated during the initial operation of the time management device 10, power is supplied and the current time (the current time calculated by the RTC module) may be displayed.

In addition, the transition of the time management device 10 from the standby state to the counting state may be performed by rotation of the time management device 10, detection of a separate sensor, or the like. After the time management device 10 is turned on, a state in which only the current time is displayed because the user does not perform an additional operation is a'standby state'. The standby state may be a state in which the current time is not displayed according to the user's setting change.

If the current time is displayed, if the user rotates the time management device 10 in a desired direction, the time displayed on the corresponding surface can be directly entered into the counting state. However, if the time management device 10 is in an ON state or a state in which the current time is not displayed, the standby state may be released through a separate motion detection sensor (not shown) that detects whether a user is in proximity. Alternatively, if the time management device 10 is touched and moved or tapped, the sensor unit 200, which will be described later, detects it and releases the standby state.

Of course, the current time may always be displayed without a separate standby state according to the user's setting, and counting may be started immediately when the time management device 10 is rotated.

This basic setting change is made in the app of the user terminal, and the setting change is transmitted to and stored in the control unit 400 to be described later.

Hereinafter, the hardware configuration of the time management device 10 will be described.

1 to 3, the time management apparatus 10 has a polyhedral shape and includes an output unit 100, a sensor unit 200, a power supply unit 300, and a control unit 400. The sensor unit 200, the power unit 300, and the control unit 400 are installed inside the cube-shaped output unit 100. In the present embodiment, the time management device 10 is described as an example in the form of a cube of a cube, but if the time management device 10 can maintain a stationary position without rolling, it may have several polyhedral shapes such as an octahedron and a dodecahedron. .

The output unit 100 is a term that refers to all sides of a cube. The output unit 100 includes a display surface 110 set to always display the current time, a first operation surface 120, a second operation surface 130, and a second operation surface 120 used to count different times according to the user's needs. It includes a three operation surface 140 and a fourth operation surface 150. The cover 162 is coupled to open and close the remaining surface on which they are not formed. A light emitting unit 170 is provided on the display surface 110 and the first operation surface 120 to the fourth operation surface 150, and a speaker 180 is installed inside the output unit 100.

However, this is only an exemplary form, and the cover 162 that can be opened and closed may be omitted, and the light emitting unit 170 may not be provided on the first to fourth operation surfaces 120 to 150. When the light emitting unit 170 is not provided on the first operation surface 120 to the fourth operation surface 150, the current time and a counting time to be described later (which is changed by starting a count up or a count down) Time) can all be displayed.

1 and 2, the display surface 110 is a surface that displays the current time, and the time is displayed by the light emitting unit 170. The display surface 110 displays the current time in connection with the RTC module 440 to be described later. When the counting time is displayed on the display surface 110 together, the display surface 110 may include an area displaying the current time and an area displaying the counting time. Alternatively, when the counting time is displayed according to a user setting change in the app, it may be configured to selectively determine whether to display the current time and display or omit it.

The display surface 110 is set so that the number display direction does not lie down or upside down, regardless of which surface of the output unit 100 faces upward. That is, if the display surface 110 is the direction the user looks at, the number of times displayed on the display surface 110 is always set so that the top and bottom match the user's gaze. Accordingly, the time displayed on the display surface 110 is rotated to match which of the first to fourth operation surfaces 120 to 150 faces the upper side of the cube and is displayed (see FIG. 5). For convenience, the display surface 110 is defined as a surface facing the user and a front surface.

The first operation surface 120 to the fourth operation surface 150 mean the remaining four surfaces, excluding the front and rear surfaces of a cube shape, respectively. 1 and 2, the first to fourth operation surfaces 120 to 150 may be sequentially disposed. Each of the first to fourth operation surfaces 120 to 150 is also provided with a light emitting unit 170 so that time may be displayed.

When the first to fourth operation surfaces 120 to 150 are disposed in a cube-shaped upward direction, counting is started. The sensor unit 200 detects which one of the first operation surface 120 to the fourth operation surface 150 faces upward, and the control unit 400 determines it to execute a count-up or count-down function. do. The counting time is displayed as a number on the corresponding side facing upward, but is displayed in real time. That is, a change in the count-up or count-down time is displayed in real time on the upper-facing surface of the first to fourth operation surfaces 120 to 150.

Each of the first to fourth operation surfaces 120 to 150 may be formed in different colors for user convenience. Alternatively, the first to fourth operation surfaces 120 to 150 may have the same color, but may include a light emitting unit 170 that emits light in different colors. Therefore, the user can set the time management item corresponding to each side based on the color of each side. Alternatively, the user may set a time management item corresponding to each surface based on the color of the light emitting unit 170. The color of the first operation surface 120 to the fourth operation surface 150 or the color of the light emitting unit 170 are expressed in the same manner in the app, so that the user can intuitively check and set the time management item.

A cover 162 may be formed on the rear surface 160 facing the display surface 110. The cover 162 is installed to be slidably opened and closed, and may be opened for replacement of the battery 310 or parts installed in the output unit 100. The cover 162 is formed to open and close a part of the rear surface 160, and a charging terminal 164 is formed on one side of the rear surface 160 on which the cover 162 is not formed. When the cover 162 is omitted, only the charging terminal 164 may be formed on the rear surface 160, and an additional configuration such as a power button may be provided. Alternatively, the rear surface 160 may also be set to serve as an operating surface.

The charging terminal 164 is electrically connected to the battery 310 and an external power source to charge the battery 310. The charging terminal 164 may be formed in the form of a USB standard standard terminal or a standard pin generally applied to a mobile phone.

As shown in FIG. 3, the light emitting unit 170 may be provided to display time on the display surface 110 and the first to fourth operation surfaces 120 to 150, respectively. Alternatively, the light emitting unit 170 may be configured to display time only on the display surface 110.

The light-emitting unit 170 may be configured to display numbers in the form of dots or may be configured to display numbers in the form of lines. The light-emitting unit 170 may be composed of a plurality of LEDs. Alternatively, the light emitting unit 170 may be configured in the form of an LCD installed on the display surface 110 or the first to fourth operation surfaces 120 to 150. The light emitting unit 170 emits light according to a control signal transmitted from the controller 172 to display time.

The controller 172 is a kind of IC chip and controls the light emitting unit 170 according to the rotation of the time management device 10 in connection with the control unit 400 to be described later. The controller 172 may turn on/off each of the light emitting units 170 or simultaneously control the light emitting units 170. For example, the controller 172 may control the light emitting unit 170 installed on the display surface 110 to be always turned on. In the case of the light emitting unit 170 installed on the first operation surface 120 to the fourth operation surface 150, the light emitting unit installed on the upper surface of the first operation surface 120 to the fourth operation surface 150 ( 170) can be controlled to turn on.

In addition, the controller 172 controls the time display direction displayed on the display surface 110 to always be correctly displayed. To this end, the control unit 400 controls the light emitting unit 170 by receiving vertical direction information of the output unit 100 according to the rotation direction of the time management device 10.

As shown in FIG. 3, the speaker 180 may be installed inside the output unit 100. The speaker 180 outputs a notification sound by receiving a control signal from the controller 400 at a preset timing, such as when a user sets a specific notification or when time counting is completed. The notification sound output of the speaker 180 can be set and changed on an app installed on the user device.

Meanwhile, the rotation of the output unit 100 is detected by the sensor unit 200 installed inside the output unit 100.

As shown in FIG. 3, the sensor unit 200 may be installed on a structure such as a substrate provided inside the output unit 100, and is connected to the MCU 410 of the control unit 400 to be described later, thereby detecting a result of detection. Is transmitted to the MCU 410. The sensor unit 200 may be configured as a single sensor, such as a gyro sensor or an acceleration sensor, or a combination of several sensors.

The sensor unit 200 is used to detect which one of the first to fourth operation surfaces 120 to 150 is disposed toward the upper side. The detection result of the sensor unit 200 is transmitted to the control unit 400, the MCU 410 determines which side faces upward based on the detection result, and transmits a control signal to the controller 172. According to the control signal of the MCU 410, the controller 172 controls the light emitting unit 170 installed on the upper-facing surface to emit light, so that the time of the corresponding surface is counted and the counting time may be displayed.

As shown in FIG. 3, the power supply unit 300 may include a battery 310 and a battery management unit 320. Although not shown in the drawing, the power supply unit 300 may further include a residual amount display circuit that senses and displays the remaining amount of the battery 310 as necessary.

The battery 310 may be composed of a rechargeable lithium ion battery or the like that is charged by receiving external power through the charging terminal 164. However, the battery 310 may be applied without limitation to its shape or type as long as it has a size and capacity that can be installed inside the output unit 100. The battery 310 may supply power by being electrically connected to all components requiring power supply. In the present invention, for convenience, only the flow in which the battery 310 supplies power to the output unit 100 and the power supply unit 300 is illustrated.

The battery management unit 320 protects the battery 310 from overcharging, overdischarging, and/or overcurrent of the battery 310, and communicates with the MCU 410 to transmit the state of the battery 310 to the MCU 410. Do it. The battery management unit 320 may include a protection circuit such as a Protection Circuit Module (PCM), Electrostatic Discharge (ESD) and Electromagnetic Compatibility (EMC). The MCU 410 may transmit a battery charging notification sound through the speaker 180 when the remaining amount of the battery 310 is less than a preset remaining amount through data transmitted from the battery manager 320.

Hereinafter, a control configuration of the time management device 10 will be described.

As shown in FIG. 3, the controller 400 includes an MCU 410 that controls the time management device 10 as a whole, a memory 420 that is a storage space, and a communication module 430 for communicating with a user terminal. And, it may include an RTC module 440 for accurate time display.

The MCU 410 is electrically connected to the sensor unit 200 to receive the detection result, and based on this, determines which side of the output unit 100 faces upward, and starts or stops counting time management items. Do it. In addition, the MCU 410 determines which side of the output unit 100 faces upward based on the detection result of the sensor unit 200, and adjusts the time display direction of the display surface 110 according to the side facing the upper side. It passes a control signal to the controller 172 to change.

When the counting of the operation surface in which the counting started is stopped, the MCU 410 may store and manage the counted time and a corresponding time management item in the memory 420. When the counting of the corresponding time management item is restarted, the MCU 410 retrieves the stored counting details, accumulates at the corresponding time, and controls the counting to be performed again.

The MCU 410 may transmit the control result or stored information of the time management item to the user terminal through the communication module 430, and may receive and store various data or setting values set or changed in the user terminal.

The memory 420 may be configured according to a required storage capacity, and the communication module 430 may be provided as a Bluetooth communication module. However, the types of the memory 420 and the communication module 430 are not limited thereto.

The RTC (Realtime Clock) module 440 is a module that calculates time in real time and transmits time data to the MCU 410 and the controller 172 in real time. Since the RTC module 440 cannot calculate time without power, it holds a separate battery or receives power from the battery 310 of the power supply unit 300. The current time is displayed on the display surface 110 in real time according to time data calculated in real time by the RTC module 440.

The time management items and various data of the time management device 10 described above are transmitted to an app of the user terminal. Hereinafter, the app screen of the user terminal will be described as an example.

As shown in FIG. 4A, the time management app may be implemented to display menus such as daily statistics, monthly statistics, activity analysis by user's time management items, settings, and the like. When the daily statistics are clicked, statistics for each time management item counted during the day may be provided as shown in FIG. 4B. When the monthly statistics are clicked, statistics for each time management item may be provided on a monthly basis as shown in FIG. 4C.

Similarly, on the setting screen, menus such as matching of each operation surface and time management items, registration, deletion, modification of time management items, setting start/end sound for each item, deletion of statistical data, and transmission may be provided. Changes in settings in the app may be transmitted to the MCU 410 of the time management device 10 and stored in the memory 420.

In the time management device according to an embodiment of the present invention having such a configuration, a method of using the time management device and a time management method will be described in detail by way of example.

5 is a perspective view illustrating an operation example of a time management apparatus according to an embodiment of the present invention. 6 is a diagram illustrating an example of a screen display in an application according to FIG. 5.

As shown in FIG. 5, if the user is a student, the time management item may be set as a study subject and a break. For example, the first operation surface 120 is rest, the second operation surface 130 is math, the third operation surface (not shown in FIG. 5) is physics, and the fourth operation surface 150 is time management in English. Items can be set and matched to each operating surface.

Matching of the time management item and each operation surface may be made in an app of the user terminal. Other than the time displayed on each side of the output unit 100, the letters are shown to aid understanding of the present invention. However, a separate LED may be provided on the output unit 100 to display time management items.

After matching and setting the time management items on each operation surface, the user may set the time management device 10 so that the second operation surface 130, which is the counting surface of the math item, is upward. When going to the bathroom after studying for 5 minutes in this state, the time management device 10 may be rotated so that the first operation surface 120, which is the counting surface of the rest item, is upward, as shown in FIG. 5.

Then, the counting time of the math item is stopped at 5 minutes, and since the first operation surface 120 of the rest item is disposed on the upper side, counting of the first operation surface 120 starts. When the user returns after 1 minute and starts studying again, the time management device 10 is rotated so that the desired operation surface is upward. If the user wants to study math again, the time management device 10 may be rotated so that the second operation surface 130 is upward, and if the user wants to study English, the fourth operation surface 150 is upward.

If the fourth operation surface 150 is turned upward, the counting stopped at 1 hour and 32 minutes previously studied is restarted, and the additional time is accumulated in addition to the existing time.

Here, the controlling subject of the start, stop, and restart of counting for each time management item is the above-described MCU 410, and which operation surface is facing upward is detected by the sensor unit 200 and transmitted to the MCU 410, and the MCU At 410, it is determined which side is the side facing up.

The operation of the time management device 10 may be similarly displayed on the app screen of the user terminal.

As shown in FIG. 6, while the math item is counting, the current time and ON are displayed on the app screen, and the counting time (5 minutes) in real time is displayed on the app screen. In this state, since the operation surface corresponding to the rest, English, and physical items does not face upwards of the output unit 100, it may be displayed as a STOP state.

Thereafter, when the time management device 10 is rotated for a break, the math, English, and physics items are displayed in a STOP state, the break items are displayed in an ON state, and the time counting in real time is displayed.

Depending on which operation surface is arranged toward the upper side of the output unit 100 in the same manner, counting of the operation surface starts/restarts or stops, and the same contents may be displayed on the app screen. Accordingly, the user can start/restart or stop time counting of a desired time management item by simply rotating the time management device 10. In addition, since these actions can be displayed and managed in conjunction with the app, intuitive and simple time management is possible.

Meanwhile, referring to FIG. 5, the time on the display surface 110 displaying the current time even when the first operation surface 120 faces upward or when the fourth operation surface faces upward, the vertical number of the number is displayed in the correct direction. Can be seen. This determines which operating surface the MCU 410 is placed upwards according to the detection result of the sensor unit 200, and in response to the determination result, the vertical direction of the number displayed on the display surface 110 is correctly displayed. This is because it is controlled to be able to be. According to the control signal from the MCU 410, the controller 172 controls the light emitting unit 170 to change the display direction of the number, so that the number can always be displayed in the correct direction on the display surface 110 viewed by the user. .

A brief description of such a time management method according to the order of the control flow is as follows.

7 is a flowchart schematically illustrating a time management method according to the time management apparatus of FIG. 1 (a configuration not shown in FIG. 7 will be described with reference to reference numerals in FIGS. 1 to 6).

As shown in FIG. 7, the MCU 410 determines whether the time management device 10 is rotated (S100), and if the time management device 10 is not rotated, maintains a standby state (S120). At this time, the light-emitting unit 170 of the first to fourth operation surfaces 120 to 150 is not lit, and only the light-emitting unit 170 of the display surface 110 is lit to display the current time.

If the time management device 10 is rotated in step S100, the MCU 410 determines which operation surface is disposed toward the upper side of the output unit 100 (S200). In step S200, when the operation surface disposed toward the upper side of the output unit 100 is detected, time counting of the time management item matched to the operation surface is started (S300). Time counting may be in the form of a COUNT UP in which time is accumulated and displayed, or in a form of COUNT DOWN in which time is subtracted from a set time and displayed. The counting method can be changed on the app of the user terminal.

The MCU 410 monitors whether the time management device 10 is continuously rotated even during time counting. Since the detection result of the sensor unit 200 is transmitted to the MCU 410 in real time, when the time management device 10 is rotated (S400) during time counting, the counting of the existing operation surface is stopped and the counting result is stored in the memory. . Thereafter, the time of the time management item matched to the new operation surface arranged to face the upper side of the output unit 100 is counted (S500). Steps S400 and S500 may be repeated until the user wants to stop counting, and all counting results are stored in the memory 420 and the user terminal.

In the above-described embodiments and drawings, the current time is displayed on the display surface 110 and the counting time is displayed on the first to fourth operation surfaces 120 to 150, respectively. However, the time management device may be configured so that the current time and the counting time are displayed only on the display surface and the time is not displayed on the first to fourth operation surfaces.

What has been described above is only one embodiment for carrying out the present invention, and the present invention is not limited to the above-described embodiment, and the present invention without departing from the gist of the present invention as claimed in the following claims. Anyone with ordinary knowledge in the field to which it belongs will be said to have the technical spirit of the present invention to the extent that various changes can be implemented.
