Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack efficient methods for supporting tasks performed by multiple workers using display devices, particularly in overlapping real and virtual spaces, which hinders task efficiency.
Innovation Solution
A task support system with multiple display devices that assign virtual objects to specific fastening locations, allowing workers to efficiently perform tasks by displaying virtual objects that overlap with real space, using spatial mapping and hand tracking to guide tool placement and task progression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple workers perform tasks on multiple fastening locations simultaneously, then task completion speed increases, but coordination complexity and task assignment management become more difficult
Solution Approach 1:
The patent divides the article into multiple segments or regions, with each wearable display device assigned to a specific segment. Fastening locations are grouped into segments, and each device displays virtual objects only for its assigned segment. This segmentation allows multiple workers to operate simultaneously on different portions of the article without coordination conflicts, maintaining high productivity while reducing management complexity.
Solution Approach 2:
Each wearable display device is configured with local quality by assigning it to display virtual objects for a specific segment or region of the article. The display content is customized per device based on its assigned segment, showing only relevant fastening locations and instructions. This local quality approach enables parallel task execution across multiple workers while simplifying the information management burden.
2Loss of information
If virtual objects are displayed for all fastening locations on all devices, then complete task information is provided, but information overload and visual clutter increase
Solution Approach 1:
The patent implements segmentation by dividing fastening locations into multiple segments and assigning each wearable display device to display virtual objects for only one segment at a time. This ensures that each worker sees a manageable subset of information rather than being overwhelmed by all fastening locations simultaneously, maintaining visual clarity while preserving complete task information across the team.
Solution Approach 2:
Each display device is configured with local quality by customizing its display content to show only virtual objects relevant to its assigned segment. This targeted information display prevents information overload and visual clutter for each individual worker, while the collective output across all devices maintains complete task information coverage.
3Adaptability or versatility
If workers manually track and communicate task progress, then flexibility is maintained, but time is lost to communication overhead and coordination
Solution Approach 1:
The patent implements automatic feedback mechanisms where each wearable display device monitors and displays the completion status of fastening locations in real-time. When a worker completes a fastening location, the system automatically updates the display for other workers, eliminating the need for manual communication. This maintains task flexibility while significantly reducing communication time and coordination overhead.
Solution Approach 2:
The system enables self-service by allowing each wearable display device to automatically track and update task progress without requiring manual input or communication between workers. The devices independently monitor completion status and adjust their display content accordingly, reducing communication time while maintaining adaptability.

AI summary
According to one embodiment, a task support system is configured to support a task for a plurality of fastening locations of an article present in a real space. The task support system includes a first display device and a second display device configured to display virtual objects to overlap the real space. Each of the plurality of fastening locations is assigned to one of a plurality of groups. The first display device displays a first virtual object for a first fastening location included in a first group, the first group being one of the plurality of groups. The second display device displays a second virtual object for a second fastening location included in a second group, the second group being another one of the plurality of groups.
