Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack an efficient method for automatically attaching parts to complex supports, such as claws or pins, in industries like automobiles and cosmetics, leading to manual and labor-intensive processes that hinder productivity due to the non-repeatability of complex support geometries.
Innovation Solution
An automated installation featuring a polyarticulated system with vision systems for part and support localization, allowing real-time adaptation to unique support geometries, and gripping mechanisms like clamps or suction cups for secure attachment, enabling rapid and efficient part attachment on complex supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual attachment operations are used for parts on complex supports, then flexibility to handle non-repeatable geometries is maintained, but productivity and operational efficiency deteriorate
Solution Approach 1:
The system employs a multi-articulated robotic manipulator with dynamic positioning capabilities that can adapt its motion轨迹 to match the specific geometry of each complex support. The vision system provides real-time feedback enabling the manipulator to dynamically adjust its attachment operations for non-repeatable geometries while maintaining high-speed automated operation
Solution Approach 2:
A vision system captures images of the complex supports and provides feedback to the control system, which then adjusts the multi-articulated manipulator's positioning and gripping forces accordingly. This closed-loop feedback mechanism enables automated handling of variable geometries with the flexibility previously only achievable through manual operations
2Productivity
If automated systems are implemented for part attachment, then productivity increases, but the system becomes complex due to non-repeatable support geometries
Solution Approach 1:
The vision system acts as an intermediary between the complex supports with non-repeatable geometries and the automated manipulator. It translates visual information about support geometry into positioning data that the manipulator can use, bridging the gap between automated operation and geometric variability without requiring complex reprogramming or mechanical redesign
Solution Approach 2:
The multi-articulated manipulator is designed with universal gripping capabilities and programmable motion control that can handle various support geometries through software configuration rather than hardware modification. This multi-functionality allows a single automated system to replace multiple specialized fixtures while maintaining productivity
3Manufacturing precision
If complex supports with non-repeatable geometries are used, then part processing quality is improved, but automation difficulty increases
Solution Approach 1:
The system replaces traditional mechanical positioning fixtures with a vision-guided robotic manipulator. Instead of using custom-machined mechanical locators for each support geometry, the vision system optically identifies support features and the manipulator computationally determines attachment positions, achieving high precision through software rather than complex mechanical design
