Solution Overview

Problem

Current electronic pens lack advanced electronic components, limiting their functionality and the potential interactions with devices, as they primarily rely on touch-enabled surfaces for input, without providing intuitive ways to interact with other devices.

Innovation Solution

A device with a processor and storage that receives transmission signals from a stylus, enabling actions such as waking the device, launching applications, controlling media playback, and authenticating signatures, while an electronic pen with a motion sensor and detachable modules allows for advanced input processing and communication with devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electronic pens include advanced electronic components and sensors, then functionality and interaction capabilities are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electronic pen is divided into modular components including a sensor module with accelerometer, gyroscope, and magnetometer, a communication module for wireless transmission, and a processing unit. This segmentation allows the pen to maintain advanced functionality while reducing overall complexity through independent, specialized modules that can be manufactured and tested separately.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor module in the electronic pen is designed to perform multiple functions: detecting writing pressure, determining writing angle, recognizing gestures, and enabling device control. This multi-functionality reduces the need for separate specialized components, thereby improving versatility without proportionally increasing device complexity.

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

2Adaptability or versatility

If electronic pens include motion sensors and electronic components, then interaction capabilities with devices are improved, but manufacturing cost increases

Engineering Contradiction:
Improveinteraction capabilitiesVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Multiple sensing functions (acceleration, rotation, magnetic field detection) are merged into a single integrated sensor module within the electronic pen. This consolidation reduces the total component count, simplifies assembly procedures, and lowers manufacturing costs while maintaining comprehensive interaction capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electronic pen automatically processes sensor data locally using onboard processing capabilities, performing gesture recognition and command generation without requiring complex external processing. This self-service approach reduces the need for expensive external processing hardware and simplifies the overall system architecture.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If electronic pens transmit detailed motion data, then input precision and control accuracy are improved, but data transmission requirements and processing load increase

Engineering Contradiction:
Improveinput precisionVSAvoiddata transmission
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The electronic pen performs preliminary processing of sensor data by identifying gestures and generating commands before transmission. This preliminary action filters out redundant data and transmits only essential information, maintaining high input precision while reducing data transmission volume and processing load on connected devices.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system extracts only the most relevant motion parameters (such as acceleration thresholds, rotation angles, and gesture patterns) from the complete sensor data set for transmission. This extraction approach maintains measurement precision for critical parameters while significantly reducing the quantity of data that needs to be transmitted and processed.

Inventive Principle:
Principle #2Taking out (Extraction)
