Solution Overview

Problem

The increasing use of data input devices, such as electronic pens, requires a smarter solution for effectively changing the color of data input to electronic devices, as existing technologies lack efficient methods for dynamic color manipulation.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a data input device uses traditional color changing methods, then the device structure remains simple, but the color changing speed and responsiveness are slow

Engineering Contradiction:

Improvecolor changing speedVSAvoiddevice structure

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical color changing mechanisms with a magnetic field-based non-contact potentiometer system. The permanent magnet rotates within the magnetic resistance devices without physical contact, generating output signals that correspond to different colors. This substitution of mechanical contact with magnetic field interaction achieves rapid color changing while maintaining device simplicity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnetic field as an intermediary between the user's rotational input and the color output. The permanent magnet creates a magnetic field that interacts with the magnetic resistance devices, allowing color changes to be transmitted wirelessly through magnetic coupling without direct mechanical contact, thereby improving responsiveness and speed.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If a non-contact potentiometer with magnetic resistance devices is used, then color changing responsiveness improves, but manufacturing complexity increases

Engineering Contradiction:

Improvecolor changing responsivenessVSAvoidmanufacturing complexity

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The non-contact potentiometer assembly serves multiple functions simultaneously: it acts as both a rotational input mechanism and a color selection device. The permanent magnet's rotation position directly determines the color output without requiring separate sensing mechanisms, simplifying the overall manufacturing process despite the advanced magnetic resistance technology used.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes changes in magnetic resistance parameters as the permanent magnet rotates to different angular positions. By varying the resistance values detected by the magnetic resistance devices based on magnetic field strength at different positions, the system achieves responsive color changing through parameter variation rather than complex mechanical linkages, improving manufacturability.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If mapping information for multiple electronic devices is stored, then device compatibility and adaptability improve, but storage and processing requirements increase

Engineering Contradiction:

Improvedevice compatibilityVSAvoidstorage information quantity

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent pre-stores mapping information for multiple electronic devices in the data input device's memory before actual use. When connecting to a new device, the system can quickly retrieve and apply the appropriate color mapping without requiring real-time configuration or extensive data processing, thereby achieving broad compatibility while minimizing active storage and processing requirements.
