Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
2Reliability
If a complicate procedure is performed for operations to switch functions, then the reliability is improved, but the ease of operation deteriorates
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
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
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
