Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing processes are limited by the ability of machines to drill holes one at a time, and the number of machines required is limited by the size of the workpiece and machines, leading to inefficiencies in processing.
Innovation Solution
A processing system with an end-effector tool and a set of process tools attached to a fixture, controlled by a controller to perform tasks on a work surface, and a probe assembly for measuring hole characteristics, allowing for multiple processes to be performed simultaneously and accommodating workpiece tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple machines are used to drill holes simultaneously, then productivity is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple drilling operations into a single machine by equipping it with multiple end-effectors, each capable of performing drilling tasks. This merging approach allows simultaneous multi-hole drilling while avoiding the need for multiple separate machines, thus improving productivity without proportionally increasing device complexity
Solution Approach 2:
The machine is designed with universal end-effectors that can perform multiple functions - drilling, countersinking, and other hole-preparation operations. This multi-functionality allows a single machine to replace multiple specialized machines, improving manufacturing efficiency while reducing the overall number of machines required
2Productivity
If the size of machines is increased to handle larger workpieces, then processing capability is improved, but the number of machines that can be used is limited
Solution Approach 1:
The machine system is segmented into multiple independent end-effectors that can be distributed across the workpiece surface. Each end-effector handles a specific region, allowing the system to process large workpieces without requiring a single oversized machine, thus maintaining processing capability while managing machine footprint
3Productivity
If traditional single-hole drilling is used, then machine simplicity is maintained, but manufacturing time increases
Solution Approach 1:
The system enables continuous useful action by having multiple end-effectors drill holes simultaneously in different locations on the workpiece. This parallel processing eliminates idle time between drilling operations, significantly reducing total manufacturing time while keeping the machine continuously productive

AI summary
A processing system and a method for manufacturing a component includes a workpiece having a work surface and an end-effector tool. The end-effector tool includes a fixture, and a set of first process tools attached to the fixture in a predetermined pattern. The first process tools are configured to perform a task to the work surface. The processing system also includes a controller in communication with the end-effector tool. The controller is configured to control movement of the end-effector tool to position the first process tools relative to the work surface such that the predetermined pattern is aligned at a predetermined location relative to the work surface. The controller is also configured to control operation of the first process tools such that the first process tools perform the task to the work surface to form a first processed area at the predetermined location of the work surface.
