Description

Technical Field

[0001] The present application relates to the technical field of Sudoku game board devices, and particularly to a Sudoku game board device. Background Art

[0002] The Sudoku game is a logic game. This game not only helps improve logical thinking ability but also enhances memory and concentration. Therefore, the Sudoku game is widely loved by people of all ages, especially in the early childhood intellectual development and the elderly's brain fitness, showing significant market demand.

[0003] For children, the Sudoku game can help them cultivate logical thinking ability, problem-solving ability, and patience in the game. This is of great significance for children's intellectual development and comprehensive quality improvement. However, traditional Sudoku game devices have certain limitations in terms of operation complexity and interaction experience, which may affect children's learning interest and effect.

[0004] Similarly, for the elderly, the Sudoku game is a good brain fitness activity that can effectively prevent cognitive function degradation and keep the brain active. However, existing Sudoku game devices are usually simply designed and have single functions, making it difficult to meet the elderly's requirements for ease of operation and interestingness.

[0005] Existing Sudoku toys on the market cannot perform real-time detection on the pieces in the piece placement area.

[0033] A controller 8, which has a plurality of signal acquisition input ends, is respectively connected to the sensing signal output ends of the plurality of detection buttons in each square, and is used for detecting the triggering state of the detection button 12 in the square 11 in real time so as to judge which game piece is placed in the current square; the control signal input end of the LED lamp is electrically connected to the control signal output end of the controller;

[0034] A display screen 3, which is used for displaying game information.

[0035] It should be noted that, as Figure 1 shown, the Sudoku game board device further includes a housing 5 and a bottom plate 7, as well as a speaker 6. The speaker 6 is controlled by the controller 8.

[0036] In this embodiment, each square 11 of the piece placement area 1 is provided with three detection buttons 12, and the three detection buttons 12 are respectively located on the left side, the upper side and the right side of the square 11.

[0037] This embodiment realizes the accurate detection function of chess piece 2 by setting three independent detection buttons 12 in each square 11, which are respectively located on the left, top and right sides. This design allows the system to accurately determine the position and value of chess piece 2 according to the triggering of the detection button 12. Compared with the traditional device that needs to press multiple times to determine the information of chess piece 2, this real-time detection greatly simplifies the player's operation steps and reduces the possibility of operation errors. For children and the elderly, this simplified operation method not only increases the playability and fun of the game, but also effectively exercises their logical thinking and hand-eye coordination ability, and plays a role in early education intelligence development and intelligence prevention of dementia.

[0038] In this embodiment, the controller 8 identifies the placement of the chess pieces 2 in real time by analyzing the triggering status of the three detection buttons 12 in each square 11, and stores the triggering status of the detection buttons 12 in the same area in an internal binary array, where the same area includes the same row, the same column and the same palace area.

[0039] In this embodiment, a first magnet 13 is disposed in each of the squares 11 , and a second magnet 22 is disposed at the bottom of each of the chess pieces 2 , and the second magnet 22 and the first magnet 13 are attracted to each other.

[0040] In this embodiment, the display screen 3 is used to display various information including level information, current power level and the placement status of chess pieces 2 on the chessboard, and supports touch operation.

[0041] In this embodiment, the display screen 3 is a touch screen, which is used to receive user selection of level or switch input and display game information.

[0042] In this embodiment, the device further includes a storage module, and the storage module is connected to the controller 8 .

[0043] In this embodiment, a transparent lamp cover 15 that cooperates with the LED lamp 14 is provided in each square 11, and each transparent lamp cover 15 extends into the corresponding LED groove hole 23. This embodiment provides a Sudoku game board device, including a chess piece placement area 1, multifunctional buttons 4, and a display screen 3. By providing a plurality of squares 11 in the chess piece placement area 1, each square 11 contains a plurality of detection buttons 12, a first magnet 13, and an LED lamp 14, and the board can detect the placement state of the chess pieces 2 in real time. The controller 8 analyzes the trigger state of the detection buttons 12 in each square 11 in real time to ensure the correct placement of the chess pieces 2. The display screen 3 provides rich game information and supports touch operations, making the game operation more intuitive and convenient. The multifunctional buttons 4 have two trigger methods: long press and short press, which further simplifies the operation and improves the user experience. Generally speaking, through real-time detection and intelligent interaction, this Sudoku game board device enhances the intelligence and interest of the game, is particularly suitable for early childhood intellectual development and elderly people's intellectual development to prevent dementia, and has broad market prospects.

[0044] In this embodiment, by storing the trigger states of the three detection buttons 12 in each square 11 in a binary array, the controller 8 can obtain the placement situation of the chess pieces 2 on the entire board in real time. This method not only improves the detection accuracy of the system but also simplifies the process of data storage and processing. The system can update and analyze the board state at any time to ensure the accuracy of the game, enabling the Sudoku game device to immediately feedback the result after each operation, reducing the waiting time, and enhancing the user experience. For children and the elderly, this can help them continuously receive immediate feedback during the game process, strengthen the learning effect, and enhance their thinking ability, having a significant role in early education and intellectual development.

[0045] In this embodiment, during the stage of placing the problem chess pieces 2, the LED lamp 14 is used to display different colors to prompt the player of the correct position and value for placing the chess pieces 2, effectively reducing the probability of incorrect placement when the player sets the problem. The color prompt of the LED lamp 14 is intuitive and easy to understand, enabling the player to quickly find the correct position for placing the chess pieces 2. This design not only improves the operation efficiency of the game but also increases the interest and challenge of the game. For children and the elderly, this intuitive prompt method helps to enhance their learning interest, improve their attention and memory, and plays a role in early education and intellectual development.

[0046] During the game in this embodiment, the LED lamp 14 is used to prompt the accidental touch and drop of the problem piece 2 and its incorrect placement, and display the correctness of the result after the game ends. This design ensures the continuity and smoothness of the game process. When the player accidentally knocks off or incorrectly places the piece 2, the flashing prompt function of the LED lamp 14 can correct the error in time to avoid affecting the overall progress of the game. After the game ends, through the display of the LED lamp 14, the player can intuitively understand their game result, enhancing the interactivity and feedback of the game. For children and the elderly, this real-time feedback and error correction mechanism can effectively improve their learning effect and enhance their logical thinking ability and problem-solving ability.

[0047] In this embodiment, by using the display screen 3, the device can provide a more abundant and diverse information display, including level information, current battery power, the placement state of the board pieces 2, etc. Compared with the traditional LED array display screen, the display screen 3 has a higher resolution and richer color expressiveness, making the information display clearer and more intuitive. At the same time, the display screen 3 also supports touch operations, and the player can directly operate by touching the screen, further simplifying the game operation steps and improving the intelligence level and user experience of the device. For children and the elderly, this convenient operation and rich information display can attract their attention, improve their learning interest, and promote intellectual development and cognitive ability improvement.

[0048] In this embodiment, the controller 8 can detect and record the triggering and disconnection of the detection buttons 12 in each square 11 in real time, and obtain the placement situation of the piece 2 through the analysis of the binary array. This technology enables the system to update and feedback the placement state of the piece 2 at any time, ensuring the real-time and accuracy of the game. The player can obtain instant feedback during the game, improving the interactivity and operation experience of the game. This technology also provides a basis for subsequent game data analysis and function expansion, enhancing the intelligence level of the device. For children and the elderly, this real-time feedback mechanism helps them continuously adjust and optimize their strategies during the game, enhancing logical thinking and problem-solving abilities, and playing an educational and intellectual role.

[0049] In one embodiment, the second magnet 22 at the bottom of the piece 2 attracts the first magnet 13 in the board square 11, ensuring that the piece 2 is closely attached to the board and triggering the detection button 12 group for identification.

[0050] In this embodiment, a second magnet 22 is designed at the bottom of the chess piece 2, which attracts the first magnet 13 in the chessboard square 11, ensuring that the chess piece 2 fits tightly with the chessboard and triggering the detection button 12 group for identification. This design not only improves the stability of the chess piece 2, preventing the chess piece 2 from accidentally moving during the game, but also simplifies the identification process of the chess piece 2. Players only need to place the chess piece 2 in the square 11, and the system can automatically identify and record the information of the chess piece 2. The magnetic adsorption design improves the placement accuracy and operation convenience of the chess piece 2, enhancing the fluency and experience of the game. For children and the elderly, this stable and reliable design not only improves their operation experience, but also helps them focus more on the game, improving their logical thinking ability and hand-eye coordination ability, with the functions of early education and intellectual development.

[0051] In one embodiment, the detection of the chess piece 2 in a certain square 11 by existing products on the market is based on the number of presses by the player, and the information of the chess piece 2 detected inside the current system is displayed through the change of the indicator light. During the game, the player needs to adjust their number of presses according to the flashing of the indicator light, greatly complicating the game process. On the other hand, the system cannot detect the changes of the player's placement of the chess piece 2 in real time, and can only judge the correctness of the current position immediately after the player places a certain chess piece 2, rather than making a judgment after all the chess pieces 2 are placed, which does not conform to the ideal game process of Sudoku.

[0052] Based on this problem, this embodiment relates to an intelligent chessboard design capable of real-time detecting the placed chess pieces 2, and its implementation principle is based on the unique design of the chess pieces 2 and the chessboard squares 11. In each placeable chessboard square 11, one independently triggerable detection button 12 is arranged on each of the left, upper, and right sides. At the same time, a first magnet 13 is placed inside the center of the square 11, and an LED lamp 14 is placed at the lower side. Correspondingly, three sets of hole-drilling designs are made at the bottom of each numbered chess piece 2 at corresponding positions. The left, upper, and right sides are digital detection holes 21, and each different number corresponds to a set of special hole positions; a second magnet 22 is arranged at the center of the numbered chess piece 2, and a first magnet 13 that attracts the second magnet 22 to each other is built in each square 11 of the chess piece placement area 1; the lower side is an LED groove hole 23 to prevent interference with the LED lamp 14 after the chess piece 2 is placed on the chessboard. When the chess piece 2 is placed, the magnet can ensure that the chess piece 2 is closely attached to the chessboard, thereby triggering the set of detection buttons 12 on the chessboard. The set of detection buttons 12 pressed by different chess pieces 2 are different, which helps the system distinguish different numbers that can support up to 0-7, and only 0-6 are used here. On this basis, the system can real-time detect the triggering and disconnection of the three detection buttons 12 in each square 11, and store the triggering situation of the detection buttons 12 in the same row in an internal binary array. By analyzing this array, the system can obtain the placement situation of the chess pieces 2 at any time, instead of only updating and detecting after each step like other products on the market. In this invention, a total of 108 independent detection buttons 12 are used in the chessboard part, and an arrayed cable connection method similar to keyboard triggering is used, and a total of 24 single-chip microcomputer pins are used.

[0053] In one embodiment, the indication function of the existing products on the market for the chess pieces 2 is independent of the chess piece placement area 1, but relies on an external display screen for prompting. This design is very likely to cause disorder and error in the placement of the chess pieces 2. Therefore, during the placement process of the existing product's problem chess pieces 2, a prompting process of placing different chess pieces 2 in batches is used, that is, first place the chess pieces 2 of a certain number, and then place the next type, and this process is looped 6 times. At the same time, during this process, no prompt can be given to any chess piece 2 that may be placed wrongly. This design defect greatly complicates the player's gaming experience.

[0054] Based on this problem, this embodiment involves a function design for display and prompting in the chess piece placement area 1, and its implementation principle is based on the unique design of the chess pieces 2 and the chessboard squares 11. In each chessboard square 11 where the chess piece 2 can be placed, an LED lamp 14 is arranged, and a groove design that can accommodate it is provided at the corresponding position at the bottom of the chess piece 2, so that no interference will occur when it is placed on the chessboard. Based on different game processes, the system can control the LED lamp 14 to display different types of information, thereby optimizing the player's gaming process and experience.

[0055] During the stage of placing the problem piece 2, the LED light in the chessboard square 11 will light up and display the corresponding color according to different problem numbers. The player only needs to place the corresponding numbered piece 2 according to the color. After the piece 2 is placed, the system will automatically detect whether the placed piece 2 is correct. If it is correct, the LED light in the square 11 will go out; if it is incorrect, the LED light in the square 11 will start to flash, indicating that the placement of the piece 2 is incorrect and the player should readjust it.

[0056] During the play stage, this design can be used to prompt accidental dropping and incorrect placement of the problem piece 2. After the game starts, if the problem piece 2 in a certain square 11 is accidentally knocked off by the player or placed incorrectly, the LED light in the square 11 will start to flash, prompting the player to correct the error of the problem piece 2 to avoid interfering with the subsequent play process.

[0057] During the play stage, this design can be used for the prompting function of the piece 2. When the player needs a prompt for the next move, the system can control the empty spaces without placed piece 2 to display the color corresponding to the answer to assist the player to continue the game. The prompting function can be ended by the player manually turning it off or placing the corresponding correct piece 2.

[0058] During the stage of judging right or wrong after the game ends, this design can be used to display whether the result is correct. When all the chessboard squares 11 are filled, the system will detect whether the result is correct. If there is no error, the entire chessboard will flash simultaneously, indicating that the result is correct; if there is an incorrect placement of the piece 2, the corresponding square 11 LED will flash the color of the correct answer and stop flashing after the player modifies the answer or exits the game.

[0059] In one embodiment, existing products on the market use an LED array to form a radar screen. Each LED light corresponds to a chessboard position, and it expresses the situation of placing the piece 2 in the corresponding square 11 by controlling the color of the LED light. This design limits the information it can transmit.

[0060] Based on this problem, this embodiment includes a touchable LCD screen, which has finer display pixels and colors, and can simultaneously display diverse information, not limited to the chessboard state, including but not limited to functions such as level information, current battery level, error messages, and game prompts. The invention also supports direct touch of the screen, thereby realizing more diverse operation functions.

[0061] Compared with existing products on the market, the unique feature of this embodiment lies in the real-time reading of the chess pieces 2 on the chessboard and the intelligent and efficient interaction experience. The key technical points it is based on are as follows: A design of the grid 11 in the chessboard placement area and special chess pieces 2 based on the triple-detection button 12, the effect of which is to identify the placement situation of the chess pieces 2 in real time by judging the trigger state of the triple-detection button 12, effectively simplifying the redundant operations of players and improving the intelligence of the system. The independent LED display design for the grid 11 where the chess pieces 2 are placed, the effect of which is to greatly improve the intuitive connection between the system prompt and the placement of the chess pieces 2, reducing the identification difficulty of players and the operation difficulty. The display screen 3 is introduced, which can display diverse information, including power-on / off prompts, the placement status of the chess pieces 2 on the chessboard, the current battery level of the device, other level selection information, etc., and at the same time supports touch control, effectively improving the intelligent interaction experience. The identification function of the device detection button 12 is strengthened. Each detection button 12 can be triggered in two ways: long press and short press, increasing the operable functions of players and reducing the repetition and complexity of use.

[0062] The design of the chessboard grid 11 and special chess pieces 2 that can be recognized in real time in this embodiment: Compared with existing products on the market, this design greatly simplifies the operation process of players. During the whole game process, "placement and recognition immediately" can be achieved without players having to perform complicated additional operations. At the same time, the triggering mechanism of this design is simple, the triggering principle is reliable, no complex external parts are introduced, the number of external interfaces of the single-chip microcomputer is not increased, the cost is controllable, and there is a significant improvement in effect compared with other products, realizing an intelligent chessboard design, providing a conditional basis for diverse game functions, and having a huge technological improvement among products of the same type.

[0063] The LED light effect design of the chess piece placement area 1: Compared with existing products on the market, this design can intuitively reflect the relationship between the system-indicated chess pieces 2 and the currently placed chess pieces 2. Compared with external screen displays, players can omit the comparison steps and directly connect the chessboard grid 11 with the placed chess pieces 2, and at the same time make functions such as correct / error judgment and placement error reminder more obvious. This design effectively improves the effectiveness and significance of information expression, is convenient for players to understand and accept, improves the interaction intelligence, and there is no similar design among products of the same type. Adding an LCD digital display screen: Compared with existing products on the market, the present invention uses an LCD digital display screen instead of the radar screen composed of common LEDs on the market. This feature effectively improves the intelligence and information transmission efficiency of this toy, making it different from the intelligent chessboard designs on the market and becoming a real early education and intellectual development electronic toy. In addition to more comprehensive information displays such as remaining battery power and level selection, the addition of the digital display screen enables this toy to integrate more comprehensive guiding functions, lower the usage threshold, facilitate children's understanding, and reduce the learning cost.

[0064] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
