Modou Sudoku Brain

Modou Sudoku Brain is an intelligent Sudoku learning device designed by our company for children aged 5-12. It takes "ink screen + AI education" as the core and creates an immersive eye protection experience through paper-like display technology. The product deeply integrates traditional Sudoku games with STEAM education, aiming to cultivate children's logical thinking, concentration and mathematical reasoning ability through dynamic level-breaking, real-time error correction, voice interaction and other functions, while solving parents' concerns about electronic screens hurting their eyes.
Core design concept:

• Health first: It uses electronic ink screen (E Ink), no blue light, no flicker, and has passed the German Rhine TÜV certification. The eye fatigue index is reduced by 60% after 4 hours of continuous use.
• Fun and educational: Sudoku problem solving is broken down into 120+ fun animation levels, combined with AR effects (mobile phone required) to enhance interactivity.
• Data-driven growth: Analyze user behavior through AI algorithms, generate personalized training reports, and accurately locate weak links.

Materials and electronic components

1. Shell and structural materials

• Shell material: Made of ABS environmentally friendly plastic, RoHS certified, non-toxic, odorless, drop-resistant and wear-resistant. The body design is ergonomic, weighs only 180 grams, and measures 15cm×8cm×2cm, which is easy for children to hold with one hand
• Screen and buttons: Equipped with a 5.3-inch ink screen, a resolution of 1200×800, and supports eye protection mode (low blue light, no flicker). The operation area uses a 360° joystick (direction control) and physical buttons (digital input), which are sensitive and durable, and are suitable for children's hand strength

2. Core electronic components

Main control chip: Equipped with an ARM Cortex-M7 processor (main frequency 240MHz), low power design, and supports fast response touch operation and AI computing.
Display: 5.3-inch electronic ink screen (E Ink Carta 1200), resolution 1200×800, 16-level grayscale, paper-like display effect, no blue light damage, and battery life of up to 30 days.
Sensor: built-in three-axis gyroscope (for automatic rotation of screen direction), ambient light sensor (intelligent adjustment of backlight brightness).
Battery and charging: 2000mAh lithium polymer battery, supports Type-C fast charging (full in 2 hours), standby time ≥90 days.

3. Other components

Buttons and interfaces: physical power button, Type-C charging port, speaker (provides sound feedback).
Heat dissipation design: graphene heat conductive sheet + honeycomb heat dissipation holes to ensure long-term operation without heat.

Manufacturing process

Precision injection molding: The shell adopts an integrated injection molding process, and the edges are rounded and polished to avoid scratches; the button area is sealed with silicone, and the dust and water resistance level reaches IPX4.
Safety testing standards: Passed the national 3C certification and EU CE certification, all electronic components meet the children's toy safety standards (EN71), ensuring no radiation and no sharp parts.
Environmentally friendly coating process: The screen surface is covered with anti-fingerprint coating, which has been tested for 100,000 times; the body is sprayed with food-grade matte paint to avoid reflective interference

Product advantages

Layered advanced question bank: The questions cover three modes: 4×4, 6×6, and 9×9. The difficulty increases from "children's enlightenment" to "competition level" step by step, which is suitable for different age groups.
Intelligent voice teaching: Built-in 14 kinds of problem-solving skills analysis (such as row and column elimination method, block elimination method), through voice step-by-step guidance, to help children learn independently.
Gamification operation: The joystick controls the cursor movement, the physical button inputs the number, with the sound effect of the level and the star rating system (based on the time and the number of errors), to enhance the fun.
Real-time error correction feedback: When the input is wrong, the screen flashes prompts and automatically marks the conflicting numbers to strengthen the child's understanding of the rules.
Lightweight and portable: can be put into pockets or school bags, suitable for travel, classroom and other scenarios; supports automatic archiving function, interrupt or continue the challenge at any time.
Eye protection mode: the screen brightness can be adjusted in five levels, and has passed the German Rhine TÜV low blue light certification to reduce the impact of long-term use on vision

Made of environmentally friendly ABS plastic, RoHS certified, non-toxic, odorless, drop-resistant and wear-resistant.

The body design is ergonomic, weighs only 300 grams, and measures 18.3cm×10.2cm×2.5cm, making it easy for children to hold in one hand.

The body adopts a streamlined design, conveying a sense of speed and technology through simple lines and smooth surfaces. The remote control panel has soft keys, making the operation smooth and easy to use.

Family enlightenment: parents and children solve problems together, replace mobile games, reduce screen dependence; 10 minutes of thinking training before bed.

Classroom teaching aids: auxiliary tools for elementary school mathematics classes, used for logical thinking training or after-school interest groups.

Travel entertainment: kill time during long-distance travel and keep children focused; portable use in camping, waiting for buses and other scenes.

Competition preparation: provide high-intensity simulation training for Sudoku contestants to accumulate practical experience
