Solution Overview

Problem

Existing small terminals for mobile communication networks require complex user operations to perform functions, which can lead to errors and inconvenience, especially when used in environments where precise movement is difficult.

Innovation Solution

A small terminal that performs processes based on instructions from a connected device via a sensor-activated communication system, allowing users to operate mobile phone functions with simple movements such as pressing, holding, or wearing/removing the device, utilizing a near-field communication interface and a low-capacity battery for power efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex user operations are required to perform functions on mobile phones, then more functions can be controlled, but the ease of operation deteriorates and errors increase

Engineering Contradiction:
Improvefunction control capabilityVSAvoidoperation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces complex mechanical button pressing operations with simple ear detection mechanisms. The sensor automatically detects when the earpiece is inserted into the user's ear and triggers corresponding functions (answering calls, playing music, etc.) without requiring the user to press multiple buttons or perform complex sequences. This substitution of mechanical operation with automatic sensing resolves the contradiction by maintaining full function control while dramatically improving ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs functions automatically based on the detection of earpiece insertion. When the sensor detects that the earpiece is in the user's ear, the system self-activates appropriate functions such as answering incoming calls or playing music without requiring user intervention. This self-service mechanism allows comprehensive function control while eliminating the need for complex user operations.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If precise movements are required for operation, then operation accuracy improves, but the reliability deteriorates in environments where precise movement is difficult

Engineering Contradiction:
Improveoperation accuracyVSAvoidoperation reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent replaces precision-dependent mechanical button pressing with automatic sensor detection of earpiece insertion. The sensor detects the presence of the earpiece in the ear through simple positional detection rather than requiring precise user movements. This substitution maintains high operation accuracy while significantly improving reliability in environments where precise movement is difficult, such as when the user's hands are occupied or the user has motor control issues.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sensor acts as an intermediary between the earpiece and the mobile phone system. Instead of requiring direct user input through precise movements, the sensor mediates by automatically detecting earpiece insertion and translating it into system commands. This intermediary mechanism ensures both high accuracy in function execution and high reliability in diverse operating environments.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Duration of action of moving object

If a large battery is used in the small terminal, then the duration of action improves, but the volume of the device increases

Engineering Contradiction:
Improvebattery lifeVSAvoiddevice size
Core Design Contradiction:
Duration of action of moving objectVSVolume of moving object

Solution Approach 1:

The patent extracts the battery function from the earpiece itself and relocates it to the mobile phone. The earpiece contains only a small battery or no battery at all, serving as a passive audio output device. The mobile phone provides the main power source, eliminating the need for a large battery in the earpiece. This extraction resolves the contradiction by maintaining extended usage duration through the phone's battery while keeping the earpiece volume small.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mobile phone serves multiple functions including providing power to the earpiece, processing audio signals, and controlling various media functions. By making the phone a universal power source for the earpiece and other accessories, the system eliminates the need for large batteries in peripheral devices while maintaining extended duration of action through the phone's larger battery capacity.

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