Active Protective Glove with Motion Sensors and Risk Alarms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Personal Protection Equipment (PPE) provides only passive mitigation of injuries and fails to actively prevent incidents, as users may be unaware of potential hazards due to their awareness level and working environment complexities.
Innovation Solution
A hand protection system that detects self-motion and relative motion information between the hand and surrounding objects, evaluates the risk level, and sends alarms to alert users of potential hazards, combining passive and active protection measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional passive protective gloves with TPR buffers are used, then injury mitigation is provided, but active prevention of incidents cannot be achieved
Solution Approach 1:
The system continuously monitors hand motion and environmental data, processes this information through risk evaluation algorithms, and provides real-time feedback to the user through alarm signals. This closed-loop feedback mechanism enables active prevention by alerting users to hazards before contact occurs, transforming the passive TPR buffer into an active protection system that combines both real-time warning and passive mitigation capabilities.
2Object-generated harmful factors
If active prevention measures are added to PPE, then incident prevention capability is improved, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it processes acceleration data from the acceleration sensor, processes distance data from the distance sensor, performs risk level evaluation using integrated algorithms, and controls the alarm output. By consolidating these functions into a single multi-functional control unit, the system achieves active prevention capabilities while minimizing the increase in device complexity through functional integration rather than adding separate dedicated components for each function.
Solution Approach 2:
The system merges the passive TPR buffer protection with active sensing and warning functions into a unified protective glove system. The acceleration sensor, distance sensor, control unit, and alarm are integrated into the glove structure, combining traditional passive protection materials with modern active monitoring and warning technologies to create a hybrid protection system that delivers both injury mitigation and incident prevention.
3Measurement precision
If multiple sensors and processing units are added for risk evaluation, then detection precision is improved, but manufacturing complexity increases
Solution Approach 1:
The protective glove is divided into functional modules: the TPR buffer material provides passive protection, the acceleration sensor module detects hand motion, the distance sensor module monitors environmental hazards, the control unit processes data and evaluates risk, and the alarm module provides warnings. This segmentation allows each module to be optimized and tested independently, improving overall detection precision while facilitating modular manufacturing and assembly, thereby reducing production complexity compared to a fully integrated custom design.

AI summary
A hand protection method is provided that detects hand self-motion information and relative motion information between the hand and surrounding objects. The method also contemplates evaluating a risk level of the hand injured by surrounding objects according to the detected self-motion information and the detected relative motion information. An alarm is sounded if the risk rises above a predetermined risk level.
