Solution Overview

Problem

Current mobile devices lack the ability to remotely control applications using a stylus pen, limiting user convenience and functionality in controlling complex functions such as image capturing, video playback, and alarm settings.

Innovation Solution

A mobile device and method that utilize a stylus pen with a sensing unit, communication unit, and controller to detect the stylus pen's proximity and generate a communication channel, allowing for remote control of applications through button clicks and motion sensors, switching between control modes based on user input and stylus pen status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a stylus pen is added to enable remote control, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The stylus pen is designed as a separate, self-contained unit with integrated sensing unit, communication unit, and controller that can operate independently or in conjunction with the mobile device. The pen can be inserted into a docking station or held in a holder, allowing it to function as both a standalone control device and an accessory to the mobile device, thereby enabling remote control without permanently increasing the complexity of the main device.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The stylus pen is designed to perform multiple functions: it can be used for traditional touchscreen interaction, remote control of mobile device applications, and docking with the mobile device for charging or storage. This multi-functionality justifies the added complexity by providing versatile operational capabilities that enhance ease of use across different scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If communication channel is established for remote control, then ease of operation is improved, but use of energy increases

Engineering Contradiction:

Improveease of operationVSAvoiduse of energy

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The communication channel between the stylus pen and mobile device is established periodically rather than continuously. The sensing unit detects the presence of the stylus pen at intervals, and the communication unit establishes or terminates the communication channel based on these periodic detections, thereby reducing energy consumption while maintaining remote control functionality.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The stylus pen includes its own power source and autonomous sensing capabilities, allowing it to independently detect its presence and establish communication without requiring constant power supply from the mobile device. The pen can autonomously manage its own energy consumption by activating communication only when needed for control operations.

Inventive Principle:

Principle #25Self-service
