Wearable Image Capture for Worker Range Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing devices in production sites often create blind spots, making it difficult to accurately capture the work range of workers, and can impose a psychological burden due to fixed positioning that may capture a worker's face.
Innovation Solution
A work management system featuring an image capturing device worn by the worker, which captures images of their work range and transmits them to a server device, allowing for flexible positioning and reducing psychological burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an image capturing device is provided at a fixed position on the production site, then the device structure is simple and easy to install, but blind spots are formed by machines and workers' positions, making it impossible to accurately capture the work range
Solution Approach 1:
The image capturing device is transformed from a fixed installation to a wearable device that moves with the worker. The capturing position dynamically follows the worker's movements, ensuring the work range is always within the capturing scope without requiring multiple fixed devices.
Solution Approach 2:
A single wearable image capturing device serves multiple purposes: capturing work range images, monitoring worker operations, and adapting to different work positions. This multi-functional approach eliminates the need for multiple specialized fixed cameras.
2Object-affected harmful factors
If an image capturing device is provided at a fixed location, then the installation is simple, but the device captures the worker's face, imposing a great psychological burden on the worker
Solution Approach 1:
The capturing perspective dynamically shifts with the worker's movements and orientation. The device captures images from the worker's field of view rather than from a fixed overhead position, naturally avoiding face capture while maintaining work range visibility.
Solution Approach 2:
The wearable device acts as an intermediary between the worker and the monitoring system. It captures images from the worker's perspective without directly observing the worker's face, serving as a buffer that protects worker privacy while enabling work monitoring.
3Measurement precision
If multiple image capturing devices are provided to eliminate blind spots, then the work range capture accuracy improves, but the device complexity and cost increase
Solution Approach 1:
Instead of using multiple fixed devices to cover all possible positions, a single wearable device dynamically adjusts its capturing position to follow the worker. This ensures complete coverage of the work range regardless of worker movement, eliminating blind spots without increasing device quantity.
Solution Approach 2:
The wearable device copies the worker's position and movement patterns. By attaching the device to the worker, it replicates their spatial trajectory, ensuring the work range remains consistently within the capturing scope without requiring additional devices at various locations.
