Solution Overview

Problem

Wearable devices often perform unintended operations due to their functions, causing user inconvenience, especially when the user is driving a vehicle.

Innovation Solution

A wearable device equipped with a sensor unit to detect user movements and a control unit to determine the user's state, allowing it to operate in a mode that performs preset functions or avoids them, and enabling communication with vehicles to enhance user convenience during driving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wearable device provides various functions based on collected information, then the functionality and versatility are improved, but unintended operations occur causing user inconvenience

Engineering Contradiction:
ImprovefunctionalityVSAvoidoperation accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The control unit continuously monitors sensor data and user actions, comparing detected movements against predefined criteria to determine whether to activate or suppress functions. This feedback mechanism ensures that functions are only executed when genuine user intent is detected, preventing unintended operations while maintaining full functionality availability

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The wearable device dynamically adjusts its operational state based on real-time sensor input. The system transitions between different operational modes (active vs. inactive) depending on whether user movements meet the threshold for intentional interaction, allowing the device to adapt its behavior to the current context

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the wearable device detects user movements to activate functions, then the ease of operation is improved, but false gesture triggers occur causing unintended operations

Engineering Contradiction:
Improvegesture recognitionVSAvoidgesture accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system adjusts the sensitivity threshold for gesture detection based on contextual parameters such as detected activity state and movement patterns. By dynamically changing the parameter thresholds for what constitutes a valid gesture, the system maintains ease of operation for genuine user actions while filtering out false triggers from incidental movements

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The control unit pre-establishes criteria for valid gestures and uses preliminary sensor data analysis to predict whether detected movements are likely to be intentional. This preliminary assessment allows the system to prepare appropriate responses while avoiding activation from accidental movements

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the wearable device operates with full functionality during driving, then the versatility is improved, but user safety and convenience deteriorate due to unintended operations

Engineering Contradiction:
Improvefunction availabilityVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system applies different operational rules to different functions based on the driving context. When driving is detected, the system selectively suppresses functions that could cause distraction or unintended operations while maintaining availability of essential functions, creating localized quality differences in function accessibility

Inventive Principle:
Principle #3Local quality
