Pressure-Sensitive Whiteboard Pen Pattern Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic whiteboard pens require continuous power, leading to inconvenience, environmental concerns, and high costs, and fail to accurately represent the unique writing styles of different users due to their reliance on electric transmission and print form.
Innovation Solution
A whiteboard writing instrument with a changeable pattern on its outer surface that varies with pressure, allowing a detection device to gather information on writing strokes and forces, eliminating the need for power storage and enabling the projection of written content onto the whiteboard, while distinguishing between different user writing styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional electronic whiteboard pens are used, then writing contents can be transmitted to the whiteboard, but continuous power supply is required which causes inconvenience and environmental issues
Solution Approach 1:
The whiteboard pen uses the mechanical pressure from the user's hand to directly drive the writing terminal, eliminating the need for external power sources. The system serves itself by converting the user's writing action into the driving force for the writing terminal.
Solution Approach 2:
The patent replaces the electronic power-based system with a purely mechanical system. The writing terminal is directly connected to the pressure-sensitive component, using mechanical pressure to drive the writing process without electrical power.
2Measurement precision
If conventional electronic whiteboard pens are used, then writing contents can be displayed, but the writing style differences of different users cannot be accurately represented
Solution Approach 1:
The system continuously detects the pressure applied by the user through the pressure-sensitive component and feeds this information back to control the writing terminal. This feedback mechanism ensures that the writing style and force variations of different users are accurately captured and represented.
Solution Approach 2:
The patent changes the parameter of pressure detection to capture writing style differences. By measuring the pressure applied by the user, the system can distinguish between different writing styles and forces, transforming abstract writing actions into detectable physical parameters.
3Productivity
If conventional whiteboard pens are used, then writing can be done, but the pens must be replaced frequently and contents are difficult to clear
Solution Approach 1:
The whiteboard pen integrates multiple functions: it detects pressure, drives the writing terminal, and transmits writing information to the whiteboard. This multi-functional design eliminates the need for separate pens and erasers, improving writing efficiency and reducing replacement frequency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous operation without power storage and accurately represents varying writing styles by projecting images based on pressure variations, enhancing user interaction and reducing environmental and cost issues.
Implementation Method 1
a pressure-sensitive component disposed in the housing and configured to detect a pressure from the whiteboard when the user holds the whiteboard writing instrument to write contents on the whiteboard
Implementation Method 2
a projection device coupled with the detection device and configured to project an image corresponding to the contents onto the whiteboard according to the information
Data Source
AI summary
An interactive whiteboard system and a whiteboard writing instrument thereof are provided. The interactive whiteboard system comprises a whiteboard, a whiteboard writing instrument, a detection device and a projection device. The whiteboard writing instrument comprises a housing and an internal element that has a writing terminal. The writing terminal receives a pressure from the whiteboard when a user holds the whiteboard writing instrument to write contents on the whiteboard. The housing presents a pattern, which experiences a variation according to the pressure so that the detection device detects the variation of the pattern to get information corresponding to the contents. The projection device projects an image corresponding to the contents onto the whiteboard according to the information.
