Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated tooling systems for manufacturing and assembly operations require multiple configurations for different workpiece shapes, leading to inefficiencies due to the need for multiple sets of tooling assemblies and end effector tools, which are time-consuming to adjust and costly to maintain.
Innovation Solution
An automated transforming tooling system with motorized joints and a quick-change tooling system that allows for adjustable positioning of end effector tools, enabling the same tooling assembly to accommodate various workpiece configurations by automatically repositioning and quickly changing tools, reducing the need for multiple tooling sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sets of tooling assemblies and end effector tools are used for different workpiece shapes, then the system can accommodate various workpiece configurations, but the time required to adjust between different tooling sets increases and maintenance costs increase
Solution Approach 1:
The patent implements a universal tooling assembly design where a single robotic arm with interchangeable end effectors can handle multiple workpiece configurations. The end effector tools are designed with adjustable components and can be quickly swapped to accommodate different workpiece shapes, eliminating the need for multiple dedicated tooling assemblies for each workpiece type.
Solution Approach 2:
The tooling assembly incorporates dynamic, adjustable components including motorized actuators and reconfigurable fixtures that can be repositioned and reconfigured on-the-fly. This allows the same tooling assembly to adapt to different workpiece geometries without requiring complete tooling changes, reducing adjustment time while maintaining versatility.
2Adaptability or versatility
If multiple sets of tooling assemblies and end effector tools are maintained for different workpiece shapes, then various workpiece configurations can be processed, but the cost of purchasing, storing, and maintaining numerous tooling sets increases
Solution Approach 1:
The system employs a universal robotic manipulator with a standardized interface that can accommodate multiple end effector tools. This universal platform approach allows a single base tooling assembly to perform multiple functions by simply changing the end effector, significantly reducing the total number of tooling sets needed while maintaining the ability to process various workpiece configurations.
Solution Approach 2:
The patent implements a tooling management system where end effector tools can be quickly discarded (removed) from one application and recovered (reinstalled) for another application. This rapid tooling change capability allows the system to maintain versatility across different workpiece types without the permanent overhead of maintaining multiple complete tooling assemblies simultaneously.
3Reliability
If tooling assemblies are designed with fixed configurations, then the structure is simpler and more reliable, but the ability to adjust to different workpiece shapes is limited
Solution Approach 1:
The tooling assembly incorporates dynamic elements such as motorized actuators, adjustable linkages, and reconfigurable fixtures that maintain structural integrity while enabling adaptation to different workpiece shapes. The robotic arm itself provides a stable, reliable base structure with programmable motion, while the end effectors provide the necessary adjustability through controlled mechanical movements.
Solution Approach 2:
The tooling assembly is divided into modular segments: a stable, reliable robotic arm base and interchangeable end effector modules. This segmentation allows the base structure to maintain fixed, reliable configurations while the modular end effectors provide adaptability. Each module can be independently designed for reliability or versatility as needed.
