Solution Overview
Problem
Existing methods struggle to accurately manage work information, particularly when handling delicate items or tools with unique shapes, as they fail to effectively determine the strength of touch and surface concave-convex states using wearable sensors.
Innovation Solution
A wearable sensor system that includes a sensor worn by workers to receive data from a sensing object, transmitting this data to a terminal for analysis, allowing for determination of the work content and displaying the results, which can include pressure sensors integrated into gloves or other wearable devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a pressure sensor or wearable object is worn on the body to collect touching strength information, then work information can be acquired, but it becomes difficult to determine what a touched object is like from the sensor data alone
Solution Approach 1:
The patent combines multiple sensing functions into a single wearable device. The wearable sensor integrates both touching strength detection capabilities and object shape detection capabilities, allowing the system to simultaneously acquire both types of information without requiring separate sensing systems. This merging resolves the contradiction by enabling comprehensive data collection from one unified sensor platform.
Solution Approach 2:
The wearable sensor acts as an intermediary between the worker and the work object. It captures both the mechanical interaction (touching strength) and the geometric characteristics (shape) of the object, mediating the transfer of information from the physical interaction to the digital domain. This intermediary function allows comprehensive work information to be acquired without directly requiring complex analysis of the object itself.
2Productivity
If wearable sensors are used to detect work state, then worker and work can be managed, but the sensors cannot determine object characteristics like shape or surface state
Solution Approach 1:
The wearable sensor is designed with multi-functionality, serving both productivity management purposes (detecting work state, touching strength) and object characterization purposes (detecting shape, surface state). This universal design allows the same device to support multiple functions simultaneously, resolving the contradiction between work management efficiency and information completeness.
Solution Approach 2:
The patent merges object detection functions with worker monitoring functions in a single wearable system. By combining shape detection capabilities with touching strength measurement, the system achieves both productive work management and comprehensive object information acquisition without requiring separate systems.
3Ease of operation
If simple wearable sensors are used for work monitoring, then the system is easy to operate, but the sensors cannot detect surface concave-convex states or touching strength
Solution Approach 1:
The wearable sensor utilizes changes in physical parameters (such as capacitance, resistance, or voltage) in response to mechanical deformation caused by touching different objects. By detecting these parameter changes, the sensor can infer both touching strength and object shape characteristics while maintaining a simple wearable form factor that is easy to operate.
Solution Approach 2:
The patent replaces complex mechanical sensing mechanisms with electronic or electromagnetic sensing methods. Instead of using intricate mechanical structures to detect touching strength and shape, the wearable sensor uses electrical parameters that change in response to mechanical interaction, achieving high measurement precision with a simple, easy-to-operate device.
