1Productivity
If workers perform manual tasks requiring delicate handling and dexterity, then task completion is achieved, but fatigue increases and part breakage occurs
Solution Approach 1:
The sensing glove incorporates multiple sensors (force sensors, motion sensors, temperature sensors, proximity sensors, and imaging sensors) that continuously monitor task performance parameters. This feedback mechanism provides real-time data on force application, motion trajectories, temperature, and proximity to targets, enabling workers to adjust their actions to prevent part breakage while maintaining productivity.
Solution Approach 2:
The patent replaces subjective human judgment and manual control with an automated sensing and feedback system. The mechanical sensing glove with digital sensors substitutes for human sensory limitations, providing objective, quantifiable measurements of task parameters that enable more reliable and consistent performance.
2Measurement precision
If multiple sensors are integrated into the sensing glove to capture comprehensive task data, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent integrates multiple different sensor types (force, motion, temperature, proximity, and imaging sensors) into a single unified sensing glove device. This merging of multiple sensing functions into one wearable device enables comprehensive task parameter measurement while maintaining a compact, user-friendly form factor.
Solution Approach 2:
The sensing glove is designed as a multi-functional device that simultaneously performs force sensing, motion tracking, temperature monitoring, proximity detection, and imaging. This universal design allows a single device to capture comprehensive task data across multiple dimensions, improving measurement precision without requiring separate devices for each parameter.
