Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing systems face challenges in efficiently transferring components of varying sizes without requiring significant modifications, leading to increased costs and time in the manufacturing process.
Innovation Solution
A part transfer system comprising a movable support, arms with end effectors having modular dividers and vacuum ports, and a control system that allows secure transfer of parts by creating a vacuum between the end effector and the part, enabling the system to accommodate parts of different sizes using detachable partitions and vacuum sources at both the end effector and kitting tray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single part transfer system is used to transfer components of varying sizes, then manufacturing costs and time are reduced, but the system must accommodate different part sizes without significant modifications
Solution Approach 1:
The end effector is divided into multiple detachable partitions that can be reconfigured based on part size. Each partition can be independently attached or removed to create different configurations, allowing the same end effector to accommodate various component dimensions without requiring multiple specialized tools
Solution Approach 2:
The part transfer system is designed with universal end effectors that can handle multiple types of components through reconfigurable partitions. The vacuum port arrangement and partition design enable a single system to perform the function of transferring different sized parts, replacing the need for multiple dedicated transfer systems
2Reliability
If multiple part transfer systems are used for different component sizes, then each system is optimized for specific parts, but manufacturing costs and time increase
Solution Approach 1:
The end effector partitions are designed to be dynamically reconfigurable during operation. The detachable nature of the partitions allows quick adjustment between different configurations based on the specific part being transferred, enabling the system to adapt rather than requiring multiple fixed systems
3Adaptability or versatility
If significant modifications are made to the system for different part sizes, then the system can accommodate various components, but manufacturing costs and time increase
Solution Approach 1:
By segmenting the end effector into detachable partitions, the system achieves adaptability through simple reconfiguration rather than significant modifications. The modular design allows partitions to be attached or removed without complex assembly operations or specialized tools, maintaining ease of manufacture while providing flexibility
Solution Approach 2:
The system achieves different configurations by changing the arrangement and number of active partitions rather than modifying the fundamental structure. This parameter-based reconfiguration (number of partitions, their positions) allows adaptability without physical modifications to the end effector body

AI summary
A part transfer system includes a movable support, a plurality of arms coupled to the movable support, and an end effector coupled to each of the plurality of arms. The end effector includes a body and a plurality of dividers each coupled to the body. The plurality of dividers divides the body into a plurality of partitions. The end effector includes a plurality of vacuum ports each in fluid communication with one of the plurality of partitions. The part transfer system further includes a vacuum source in fluid communication with at least one of the plurality of vacuum ports. Each of the plurality of vacuum ports is configured to draw a fluid from the plurality of partitions to establish a vacuum between the end effector and a part that is engaged with the end effector, thereby securing the part to the end effector.
