Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In advanced manufacturing environments, the calibration of multiple robots involved in collaborative fabrication becomes complex due to dependencies between robots, necessitating a method to simplify the alignment process and prevent collisions or interference during operation.
Innovation Solution
The use of alignment tools with a tip section, chamber fit section, lip, and fitting member to ensure axial alignment between a fastener feed mechanism and a fastening device, allowing for precise positioning and preventing further insertion to maintain alignment, thereby reducing the chances of collision or interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple robots are used for collaborative fabrication, then productivity is improved, but device complexity increases due to calibration dependencies
Solution Approach 1:
The alignment tool serves as an intermediary device between the fastener feed mechanism and the fastening robot. It provides a standardized reference interface that mediates the alignment process, allowing independent calibration of each robot against the tool rather than requiring complex inter-robot calibration dependencies
Solution Approach 2:
The alignment tool is pre-configured with specific geometric features (chamber fit section with matching diameter, lip at predetermined distance) that establish reference positions before robot operation. This preliminary setup enables robots to be calibrated against fixed reference points rather than requiring iterative mutual calibration
2Manufacturing precision
If precise alignment is achieved between fastener feed mechanism and chamber, then manufacturing precision is improved, but device complexity increases due to alignment requirements
Solution Approach 1:
The alignment tool acts as a mediator that translates complex alignment requirements into simple geometric matching. The chamber fit section's diameter matches the chamber's inner diameter, and the lip's position corresponds to the desired fastener delivery point, providing intuitive mechanical references that simplify the alignment process
Solution Approach 2:
The patent replaces complex mechanical alignment systems with simple geometric interference fits. The chamber fit section's precise diameter match with the chamber creates a self-aligning mechanical interface, eliminating the need for complex adjustment mechanisms or sensors
3Reliability
If axial alignment is ensured with the chamber, then reliability is improved by reducing collision chances, but ease of operation decreases due to alignment constraints
Solution Approach 1:
The alignment tool serves as a protective intermediary that physically defines the safe operational envelope. The lip positioned at a predetermined distance from the chamber end acts as a mechanical stop and reference, ensuring the fastener feed mechanism is positioned correctly without requiring complex sensor-based collision avoidance systems

AI summary
Systems and methods are provided for aligning a fastener feed mechanism. One embodiment is an apparatus that includes an alignment tool that aligns a fastener feed mechanism with a chamber of a fastening device that receives fasteners. The alignment tool includes a tip section having a diameter less than a diameter of the chamber, a chamber fit section that extends from an end of the tip section in a lengthwise direction and has a diameter corresponding with the diameter of the chamber, a lip that protrudes radially from the chamber beyond the diameter of the chamber, and a fitting member that extends from the lip in the lengthwise direction.
