Electronic Pen Color Mixing Through Pressure, Tilt, And Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic pens are limited by fixed color palettes, leading to a restricted number of output colors and difficulty in accurately mixing desired colors, causing user confusion and inefficiency in creating vivid drawings.
Innovation Solution
An electronic pen that utilizes touch pressure, inclination angle, and rotation angle of the pen head to simulate colors, with a color combiner to mix different colors based on detected data, and a color recorder to store and recall color combinations.

Engineering Contradiction Analysis
1Quantity of substance
If a fixed palette with limited colors is used, then the device complexity is reduced, but the number of output colors is limited and drawings cannot be vivid
Solution Approach 1:
The palette transitions from a fixed static structure to a dynamic one where color sections can be selectively activated and deactivated. The processor dynamically determines which color sections to activate based on touch detector inputs (pressure, inclination angle, rotation angle), allowing the system to provide a virtually unlimited range of colors through dynamic combination rather than requiring all colors to be permanently displayed.
Solution Approach 2:
The color output is segmented into multiple independent color sections that can be individually controlled. Instead of selecting from a fixed set of complete colors, the system divides colors into component sections that can be independently activated and combined, enabling flexible color creation through selective segmentation of the color spectrum.
2Quantity of substance
If a palette with many colors is provided, then the number of output colors increases, but the user feels fuzzy and confuse in selection of colors
Solution Approach 1:
The system incorporates a touch detector that provides real-time feedback to the processor about user interactions (pressure, inclination angle, rotation angle). This feedback loop allows the processor to dynamically adjust which color sections are activated based on the user's intended action, making color selection intuitive and eliminating the confusion of browsing through numerous static color options.
Solution Approach 2:
The system enables users to create their own colors through natural pen movements and pressures rather than requiring them to search through pre-defined palettes. The touch detector and processor work together to automatically determine and activate the appropriate color sections based on user input, allowing users to self-generate colors as needed without manual selection from extensive lists.
3Adaptability or versatility
If color mixing is provided through grey level selection, then color combination capability is added, but the user cannot exactly determine grey levels and needs to operate repeatedly
Solution Approach 1:
The manual mechanical process of repeatedly adjusting grey levels is replaced with an automated electronic system. The touch detector automatically measures physical parameters (pressure, inclination angle, rotation angle) and the processor automatically calculates and activates the corresponding color section combinations, eliminating the need for manual grey level adjustment and repeated operations.
Solution Approach 2:
The system changes the controlling parameters from abstract grey level values to physical touch parameters (pressure, inclination angle, rotation angle). This parameter transformation allows users to naturally control color mixing through physical pen movements rather than manually adjusting numerical grey levels, making the process more intuitive and eliminating repeated trial-and-error operations.
4Ease of operation
If the electronic pen is used to point color sections, then color selection is simplified, but the number of output colors remains limited by the fixed palette
Solution Approach 1:
The system maintains the simple pointing interaction but dynamically expands the color output beyond the fixed palette. When the user points at or touches a color section, the processor dynamically determines additional color sections to activate based on touch parameters, transforming a simple selection action into a dynamic color generation process that provides unlimited color possibilities while maintaining ease of operation.

AI summary
A device for combining different colors on a computer screen by using an electronic pen includes: an electronic pen having a pen head; a palette capable of being displayed in a screen of a display; the palette including a plurality of color sections of various colors; a touch detector serving to detect a contact angle and pressure of the pen head touching one color section of the palette for determining an amount of a dye and the hue of the color touched; a touch converter serving for converting the angle and the pressure to a hue and an amount of dye so that when the electronic pen is used to writer or draw, the output from the pen head having the color; a color combiner used to mix different colors of the color sections which are touched by the pen head continuously so as to obtain a mixing color.
