Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively simulate and train workers on cooperative tasks between successive works in a work line, limiting efficient learning and collaboration.
Innovation Solution
A simulation system that utilizes virtual space to reproduce a work environment, incorporating motion capture and model workers to teach efficient cooperation between first and second workers through synchronized model motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional training methods are used for cooperative tasks, then workers can learn individual operations, but they cannot effectively learn cooperation between successive works
Solution Approach 1:
The patent creates virtual copies of workers (first virtual worker and second virtual worker) that replicate real worker actions and movements. These virtual workers are drawn in the virtual space to demonstrate proper cooperative techniques, allowing trainees to observe and learn from the copied motions without requiring complex physical training setups with multiple real workers.
Solution Approach 2:
The patent transitions from physical three-dimensional space to virtual two-dimensional display space. By projecting the work line and virtual workers onto a display device, the system enables cooperative training in a simplified visual environment while maintaining the essential spatial relationships and interaction patterns of the actual work cooperation.
2Ease of operation
If multiple workers are trained separately on individual works, then individual skill development is achieved, but collaboration and coordination between workers are not improved
Solution Approach 1:
The patent merges the training of multiple workers into a single integrated virtual environment. The first virtual worker and second virtual worker are displayed together in the same virtual space, showing their interactions and coordination. This allows trainees to simultaneously observe both individual operations and their coordination, combining what would otherwise require separate training sessions.
3Loss of information
If physical demonstrations of cooperative work are provided, then workers can observe real motions, but training space requirements and setup complexity increase
Solution Approach 1:
Instead of requiring physical space for real worker demonstrations, the patent creates virtual copies of workers that can be displayed on a screen. The virtual workers replicate the motions and interactions of real workers, preserving the essential motion information while eliminating the need for large physical training spaces and complex physical setups.

AI summary
A work line includes: a first work carried out by a first target worker; and a second work carried out by a second target worker on a resultant product of the first work. A first model motion is a model motion when the first target worker passes the resultant product of the first work to the second target worker. A second model motion is a model motion when the second target worker receives the resultant product of the first work from the first target worker. When the first target worker carries out the first work in a virtual space, a simulation system draws a first model worker performing the first model motion in the virtual space. When the second target worker carries out the second work in the virtual space, the simulation system draws a second model worker performing the second model motion in the virtual space.
