Solution Overview

Problem

Existing wearable devices lack the ability to dynamically adjust their operation modes in response to changes in user behavior or environmental conditions, potentially leading to unsafe or ineffective interactions.

Innovation Solution

A wearable device equipped with sensors and control modules that can detect pattern changes in sensor data and utterance triggers, allowing it to switch to an intervention blocking mode to stop the generation of external force when hazardous situations are detected, such as falls or sudden stops.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wearable device continuously generates external force to assist user movement, then the assistance function is improved, but the safety risk increases when hazardous situations occur

Engineering Contradiction:
Improveassistance functionVSAvoidinjury risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The wearable device dynamically switches between different operation modes (normal mode and intervention blocking mode) based on real-time sensor data analysis. The driving module adjusts its operation from generating external force to stopping force generation, enabling the system to adapt to changing user conditions and eliminate harmful effects during hazardous situations

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device continuously monitors sensor data (acceleration, velocity, position) and uses this feedback to detect hazardous situations. When abnormal patterns are detected, the system triggers an intervention blocking mode to stop external force generation, creating a closed-loop control system that prevents harmful effects

Inventive Principle:
Principle #23Feedback

2Productivity

If the wearable device operates in normal mode to provide assistance, then the productivity is improved, but the safety control capability deteriorates when unexpected situations occur

Engineering Contradiction:
Improveassistance efficiencyVSAvoidsafety control
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The operation mode is dynamically adjusted based on real-time sensor data analysis. The system transitions from normal operation (high productivity) to intervention blocking mode (high safety control) when hazardous situations are detected, allowing the device to optimize between productivity and safety control based on current conditions

Inventive Principle:
Principle #15Dynamics

3Reliability

If the wearable device monitors sensor data continuously to detect hazardous situations, then the safety monitoring capability is improved, but the device complexity increases

Engineering Contradiction:
Improvesafety monitoringVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The processor performs multiple functions using the same hardware resources: it processes sensor data for hazardous situation detection, controls the driving module operation, manages mode switching, and handles safety monitoring. This multi-functionality approach improves safety monitoring capability while minimizing the increase in device complexity

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