Writing device, intelligent writing board and method for setting color of electronic handwriting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent blackboard systems struggle to accurately determine and switch between different colors of electronic handwriting, requiring cumbersome software-based settings that do not align with the teaching habits of users.
Innovation Solution
A writing device with a detection component to identify the use state of a writing pen, such as a pressure sensor or state switching key, communicates this data to an intelligent writing board to automatically set the color of electronic handwriting, using near-field or Bluetooth communication, and optionally includes a containing part and color determination components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software-based color settings are used in existing intelligent blackboard systems, then color switching functionality is provided, but the operation becomes cumbersome and does not align with user habits
Solution Approach 1:
The writing device automatically detects its own use state through integrated sensors and autonomously transmits color-related information to the intelligent writing board, eliminating the need for manual software color settings. The system serves itself by self-detecting writing/non-writing states and self-configuring color parameters.
Solution Approach 2:
The patent replaces manual software-based color selection with automatic sensor detection. Pressure sensors, state switching keys, or color sensors physically detect the writing state and pen color, then automatically transmit this information via communication modules, substituting mechanical/physical detection for software-based manual configuration.
2Productivity
If manual color setting methods are used, then color customization is possible, but the efficiency of electronic handwriting conversion is reduced
Solution Approach 1:
The writing device pre-configures color-related information based on detected use state before actual writing occurs. The system proactively determines and transmits color parameters in advance, so that when writing begins, the color is already configured, eliminating time loss during the writing process.
Solution Approach 2:
The system continuously monitors the use state through sensors and provides real-time feedback by automatically adjusting and transmitting color information. This closed-loop feedback mechanism ensures the color setting always matches the current writing state, maintaining high conversion efficiency without manual intervention.
3Measurement precision
If automatic detection components are added to the writing device, then color switching accuracy is improved, but the device structure becomes more complex
Solution Approach 1:
The writing device integrates multiple functions into a single compact unit: the detection component serves both as a structural element (containing part) and a sensing element. The same housing that contains the writing pen also houses the detection components, eliminating the need for separate detection devices and reducing overall structural complexity.
Solution Approach 2:
The patent merges the containing part with the detection component into a unified structure. The containing part that holds the writing pen also incorporates pressure sensors, state switching keys, or color sensors, combining mechanical containment with electronic detection functions in one integrated component.

AI summary
A writing device, an intelligent writing board and a method for setting a color of electronic handwriting are provided. The writing device includes: a detection component, configured to obtain detection data of a use state of a writing pen, where the use state includes a writing state and a non-writing state; a communication component, configured to transmit the detection data and color-related information of the writing pen to the intelligent writing board, so that the intelligent writing board determines the use state of the writing pen according to the detection data, and when the use state of the writing pen is determined to be the writing state, a color of electronic handwriting of the writing pen obtained during the writing state of the writing pen is set to be a color corresponding to the color-related information.
