Solution Overview

Problem

Terminal devices, such as wearable exercise devices, face challenges in implementing multiple functions with a single operation unit, as they require complex procedures or multiple buttons, which complicates operations and increases device size and weight.

Innovation Solution

A terminal device with a hardware operation unit, sensor, orientation determining unit, and control unit that switches functions based on orientation and vibration state, allowing multiple functions to be implemented with a simple operation on the same unit, regardless of vibration state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple buttons are installed as operation units to support a plurality of functions, then the versatility is improved, but the device complexity and weight increase

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

Solution Approach 1:

A single operation unit is designed to perform multiple functions by dynamically changing its operational mode based on detected orientation and vibration patterns. The control unit switches between different functions (e.g., volume control, track selection, mode switching) depending on the exercise activity detected, allowing one physical button to replace multiple dedicated buttons while maintaining full functionality

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

2Reliability

If a complicate procedure is performed for operations to switch functions, then the reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvefunction switching accuracyVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The operation unit automatically determines the appropriate function based on detected vibration patterns and orientation without requiring user intervention. The system self-identifies the exercise activity (running, cycling, walking) through acceleration sensor data and autonomously switches functions, eliminating the need for complex manual switching procedures while ensuring reliable function assignment

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If GUIs are displayed on a touch panel to implement various functions, then the versatility is improved, but the ease of operation deteriorates during exercise due to vibration

Engineering Contradiction:
ImprovefunctionalityVSAvoidoperability during exercise
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces the touch panel GUI interface with a physical operation unit that detects mechanical vibrations and orientation. Instead of requiring visual interaction with a screen during exercise, the system uses acceleration sensors to detect vibration patterns and a physical button for input, providing a more reliable and easier-to-use interface during dynamic exercise conditions

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