Isolated Human Work Platform for Collaborative Robotics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current platforms inside aircraft fuselage assemblies are not isolated, leading to positioning errors for robots due to human or machine motion, which affects the accuracy of end-of-arm tooling.
Innovation Solution
A base platform supports robots independently of a work platform, with the work platform being isolated to prevent motion transfer, allowing for stable positioning of robots and safe human access within the fuselage assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a shared platform is used to support both robots and human workers, then device complexity is reduced and space is saved, but positioning precision deteriorates due to motion transfer from human or machine activity
Solution Approach 1:
The platform is divided into two independent segments: a base platform supporting the robots and a work platform for human workers. This segmentation prevents motion from human activity on the work platform from transferring to the robots on the base platform, thereby maintaining positioning accuracy while keeping the overall structure relatively simple
Solution Approach 2:
The disturbing element (human workers and their equipment) is extracted from the robot support platform and placed on a separate work platform. This extraction eliminates the source of vibration and motion that would otherwise affect robot positioning, resolving the contradiction between platform simplicity and positioning precision
2Productivity
If robots are positioned inside the fuselage assembly for direct access, then productivity increases, but safety deteriorates due to lack of isolation from human workers
Solution Approach 1:
The workspace is segmented into distinct zones: the base platform zone for robots and the work platform zone for human workers. This spatial segmentation allows both robots and humans to operate simultaneously inside the fuselage assembly with improved safety, while maintaining high productivity through direct access to the work area
3Manufacturing precision
If the work platform is isolated from the base platform to prevent motion transfer, then positioning precision is improved, but device complexity increases due to additional isolation mechanisms
Solution Approach 1:
The platform carrier serves as an intermediary element that connects the base platform and work platform while providing isolation. This intermediary structure enables motion decoupling between the two platforms, improving positioning precision without requiring complex active isolation mechanisms
Data Source
AI summary
An isolated human work platform for stabilized positioning of collaborative robotics. A base platform is provided, and a work platform is positioned above the base platform for supporting one or more humans. One or more robots are supported on the base platform independently of the work platform, so that movement of the work platform does not affect the robots' positions. The work platform is isolated from the robots for stabilized positioning of the robots, so that the base platform and work platform together provide a collaborative workspace for the robots and the humans.
