Wearable External-Force Blocking for Hazardous Situation Detection
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
