Solution Overview

Problem

Existing stylus devices face limitations in intuitively and efficiently selecting a large number of line properties and attributes for computer-aided drawing applications, as they can only practically have a small number of buttons, making it cumbersome to choose from numerous colors and settings.

Innovation Solution

A method and system where a stylus interacts with a host electronic device to cycle through a list of settings, allowing a single control to select from multiple attributes, such as color and tool type, with the selected settings displayed on the stylus, enabling efficient switching between different drawing tool settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple buttons are added to the stylus to select different line properties, then the ability to select various drawing attributes is improved, but the device complexity and physical size increase

Engineering Contradiction:
Improveability to select drawing attributesVSAvoidnumber of buttons
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single button on the stylus is designed to perform multiple functions by cycling through different drawing attributes (color, thickness, style) sequentially. When the user presses the button, it advances to the next attribute in a predefined sequence, allowing one physical component to control multiple drawing properties that would otherwise require separate buttons or menu interactions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The single button operates in a periodic cycle through different drawing attributes. Each press of the button advances the selection through a repeating sequence of attributes (e.g., color → thickness → style → color...). This periodic cycling allows the user to access multiple attributes using a single repetitive action, eliminating the need for multiple buttons while maintaining full functionality.

Inventive Principle:
Principle #19Periodic action

2Device complexity

If a single button is used to cycle through drawing attributes, then the device complexity is reduced, but the time required to select specific attributes increases

Engineering Contradiction:
Improvenumber of buttonsVSAvoidtime to select attribute
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system pre-organizes drawing attributes into a logical sequence or groups related attributes together in the cycling order. Commonly used attributes are positioned earlier in the cycle, and the default starting attribute is set to the most frequently used property. This preliminary arrangement reduces the average number of presses needed to access commonly selected attributes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The electronic device provides visual feedback on the display screen showing which attribute is currently selected and what value it has. This feedback allows the user to see the changing attribute values in real-time as they press the button, enabling faster recognition and selection without needing to physically count presses or remember the cycle position.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If more drawing attributes are made selectable, then the versatility of the drawing tool is improved, but the ease of operation decreases due to more selection options

Engineering Contradiction:
Improvenumber of selectable attributesVSAvoidintuitiveness of selection
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The drawing attributes are segmented into distinct categories (color, thickness, style, pattern) and arranged in a logical sequence within the cycling order. This segmentation allows users to mentally organize the attributes and predict which category they need, making it easier to navigate through the cycle. Related attributes are grouped together in the sequence, reducing the cognitive load of selecting from a large number of options.

Inventive Principle:
Principle #1Segmentation

AI summary

The present disclosure provides a method, system and stylus for drawing tool selection. One or more drawing tool settings, each defined by user-selectable drawing tool attributes, are formed by user interaction with a user interface. A user-activated control on a stylus signals a host electronic device to select a drawing tool setting. The settings may be selected in cyclic order. When a selected drawing tool setting includes color, the host electronic device may signal the selected color to the stylus for display using a color indicator on the stylus.
