Solution Overview

Problem

Current mobile terminals, especially wearable watch-type devices, lack efficient methods for remote control and sharing of photographs taken by connected photography devices, limiting user convenience and functionality.

Innovation Solution

A watch-type mobile terminal equipped with a wireless communication unit, display unit, and controller that allows users to receive and decode preview images, transmit remote photograph commands, and share photos with other terminals, utilizing gestures and predefined inputs for control and communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If a wearable mobile terminal is used for remote control of photographing device, then portability is improved, but control precision and user interaction quality deteriorate

Engineering Contradiction:
ImproveportabilityVSAvoidcontrol precision
Core Design Contradiction:
Weight of moving objectVSEase of operation

Solution Approach 1:

The wearable mobile terminal serves as an intermediary device between the user and the photographing device. It transmits control commands (shutter release, zoom, focus) from the user to the photographing device via wireless communication, enabling remote control while maintaining portability. The terminal acts as a mediator that bridges the gap between limited wearable interface capabilities and the need for precise photographing control.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The wearable mobile terminal performs multiple functions: it serves as a remote control for the photographing device, displays preview images, transmits captured images, and provides user interface for control operations. This multi-functionality compensates for the limited size and interface capabilities of wearable devices, allowing them to perform complex photographing control tasks that would otherwise require a larger device.

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

2Loss of information

If preview image data is transmitted to wearable terminal, then remote viewing capability is improved, but power consumption increases

Engineering Contradiction:
Improvepreview image viewing capabilityVSAvoidpower consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The wearable mobile terminal receives and displays preview image data from the photographing device, enabling the user to view the preview remotely on the wearable device. This partial transmission of image data to the wearable terminal provides sufficient viewing capability for composition and framing, while avoiding the excessive action of full-resolution continuous streaming that would drain power quickly.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If remote photograph command is transmitted from wearable terminal, then remote control capability is improved, but control reliability deteriorates

Engineering Contradiction:
Improveremote control capabilityVSAvoidcontrol reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system implements feedback mechanisms where the wearable terminal receives confirmation signals from the photographing device after transmitting control commands. The terminal displays feedback information such as successful shutter release, image capture status, and transmission confirmation. This feedback loop ensures that control commands are reliably executed and provides the user with real-time status information, compensating for the potential unreliability of wireless remote control.

Inventive Principle:
Principle #23Feedback
