Manipulator Platform Alignment for Stable Object Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated platforms face challenges in stably picking up and placing objects due to deviations in the position of the manipulator relative to the station, which can result in uncertainty and instability during object transfer.
Innovation Solution
A platform system is designed with a station that includes a moving portion and a guide to facilitate stable movement, and a manipulator with a gripper having an inclined surface to accurately pick up and place objects. The system incorporates aligners, stoppers, and plungers to manage movement and position adjustments, ensuring precise object handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a manipulator is used to transfer objects on an automated platform, then automation and productivity are improved, but position deviations occur between the manipulator and station, reducing reliability
Solution Approach 1:
The station includes a moving portion that can dynamically adjust its position in response to manipulator pickup and placement actions. This dynamic adjustment compensates for position deviations, allowing the system to maintain reliability while achieving full automation of object transfer operations.
Solution Approach 2:
The system incorporates feedback mechanisms where the moving portion responds to the manipulator's actions by adjusting its position. This feedback loop corrects position errors in real-time, ensuring that automated operations maintain high reliability despite initial position deviations.
2Manufacturing precision
If the moving portion is designed to move in response to object pickup and placement, then position accuracy is improved, but device complexity increases due to additional guides and alignment mechanisms
Solution Approach 1:
The station is segmented into a stationary portion and a moving portion, each with specific functions. The moving portion handles position adjustment while the stationary portion provides structural support and guidance. This segmentation allows for simplified design of individual components while achieving high overall precision.
Solution Approach 2:
The guide structure acts as an intermediary between the moving portion and stationary portion, providing constrained movement paths. This intermediary mechanism simplifies the design by defining clear motion constraints, reducing the complexity of controlling the moving portion's position and orientation.
3Reliability
If aligners and stoppers are added to manage movement, then stability and reliability are improved, but ease of manufacture deteriorates due to additional components
Solution Approach 1:
The aligner and stopper functions are merged into integrated components that perform multiple functions simultaneously. For example, guide structures incorporate both alignment and stopping functions, reducing the total number of separate parts and simplifying the manufacturing process while maintaining high reliability.
Solution Approach 2:
Components are designed with multi-functionality, where single elements serve multiple purposes. The guide structure provides both movement guidance and position limiting functions, while the moving portion serves both as a support surface and a dynamically adjustable element. This multi-functionality reduces component count and assembly complexity.
