Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated systems for processing O-rings in mass production lack efficient synchronization and coordination between feed, indexing, and pick-and-place operations, leading to inefficiencies in the production process.
Innovation Solution
An automated mass production system with electronically synchronized feed devices, indexing devices, and pick-and-place robots, where O-ring retainers are advanced through loading and unloading positions in alignment with the feed device output, and end effectors are synchronized to pick up and install O-rings on workpieces, utilizing a control system to coordinate these operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated systems are used for O-ring processing, then productivity is improved, but synchronization and coordination between feed, indexing, and pick-and-place operations become complex
Solution Approach 1:
The patent combines multiple independent operations (feeding, indexing, pick-and-place) into a single integrated automated system with unified electronic synchronization. The control system merges the timing and coordination of all subsystems, allowing them to operate as a cohesive unit rather than separate processes, thereby improving throughput while managing complexity through integration.
Solution Approach 2:
The patent replaces manual mechanical coordination with electronic synchronization systems. Instead of using mechanical linkages or manual timing to coordinate feed devices, indexing devices, and pick-and-place robots, the system uses electronic control signals to synchronize operations, reducing mechanical complexity while maintaining precise coordination.
2Manufacturing precision
If electronic synchronization is implemented between feed device and indexing device, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical alignment and timing mechanisms with electronic synchronization. The control system uses electronic signals to precisely time the discharge of O-rings from the feed device with the arrival of retainers at the loading position, achieving high manufacturing precision through electronic control rather than mechanical means.
Solution Approach 2:
The electronic synchronization system incorporates feedback mechanisms to monitor and adjust timing and alignment between the feed device and indexing device. The control system receives information about the positions and states of various components and makes real-time adjustments to maintain precise synchronization, thereby achieving high manufacturing precision through closed-loop control.
3Productivity
If continuous synchronized installation of O-rings is achieved, then productivity is improved, but the complexity of coordinating multiple devices increases
Solution Approach 1:
The patent merges the coordination of feed devices, indexing devices, and pick-and-place robots into a unified automated system. By integrating control of all these devices under a single electronic synchronization framework, the system achieves continuous O-ring installation without the complexity of coordinating multiple independent systems, as the merged control structure streamlines the coordination process.
Solution Approach 2:
The system maintains continuous operation by ensuring that the feed device, indexing device, and pick-and-place robot operate in unbroken sequence without idle time. The electronic synchronization keeps all devices actively engaged in the production process simultaneously, eliminating interruptions and maintaining continuous useful action throughout the system, thereby maximizing productivity.

AI summary
An O-ring processing station for an automated mass production system includes: (a) at least one feed device operable to control discharge of O-rings from an output end of the feed device; (b) an indexing device having a plurality of O-ring retainers, the indexing device operable to advance each retainer to a loading position in alignment with the output end for receiving an O-ring from the feed device, and an unloading position spaced apart from the loading position for unloading the O-ring from the retainer; and (c) a pick-and-place robot including at least one end effector movable between a pick-up position in alignment with a retainer at the unloading position for removing the O-ring from the retainer, and a drop-off position spaced apart from the pick-up position for installation of the O-ring onto a workpiece.
