Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated mass production systems for processing O-rings lack efficiency in synchronizing the movement and loading of O-rings into retainers and subsequent installation on workpieces, leading to inefficiencies in the production process.
Innovation Solution
An automated mass production system that includes a feed device for discharging O-rings, an indexing device for loading and unloading O-rings, and a pick-and-place robot for synchronized pick-up and installation, with a control system to electronically synchronize the operations of these components, allowing for simultaneous processing and installation of O-rings on workpieces held by carriers moving along a track.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated mass production systems process O-rings without precise synchronization, then device complexity is reduced, but productivity decreases due to inefficiencies in the production process
Solution Approach 1:
The system performs preliminary actions by pre-positioning O-rings in retainers before the main assembly operation. The feed device discharges O-rings and loads them into retainers in advance, so that when carriers arrive at the assembly position, the O-rings are already prepared and synchronized for immediate installation, eliminating waiting time and improving productivity
Solution Approach 2:
The patent introduces an intermediary indexing device with retainers that act as a buffer between the feed device and the assembly operation. This intermediary component receives O-rings from the feed device, holds them in a synchronized manner, and presents them to carriers at the appropriate time, thereby coordinating the operations of different system components and improving overall productivity
2Productivity
If manual intervention is used for O-ring loading and installation, then device complexity is reduced, but productivity decreases due to slower processing speeds
Solution Approach 1:
The system implements self-service automation where the feed device automatically discharges O-rings, the indexing device automatically loads them into retainers, and the assembled carriers are automatically returned. This automated sequence operates without manual intervention, enabling continuous mass production at high speed while maintaining synchronization through the coordinated operation of these self-servicing components
Solution Approach 2:
The patent establishes continuity of useful action by creating an unbroken automated cycle: the feed device continuously discharges O-rings, the indexing device continuously loads retainers, carriers are continuously assembled and returned, and the system operates in a sustained continuous loop without idle periods or manual interruptions, thereby maximizing productivity
3Manufacturing precision
If O-ring loading and carrier assembly are performed simultaneously without synchronization, then device complexity is reduced, but manufacturing precision decreases due to timing misalignment
Solution Approach 1:
The system employs feedback mechanisms where sensors detect the position and status of carriers, retainers, and O-rings, and this information is fed back to the control system. The control system uses this feedback to adjust timing and coordination, ensuring that O-ring discharge, retainer loading, and carrier assembly occur in precise synchronization, thereby achieving high manufacturing precision through closed-loop control

AI summary
Processing O-rings in an automated mass production system includes advancing an O-ring retainer toward a loading position in alignment with an output end of a feed device, discharging a leading O-ring from the output end in electronic synchronization with advancement of the O-ring retainer to the loading position to initiate loading of the O-ring into the retainer prior to the retainer arriving at the loading position, after loading the O-ring into the retainer, advancing the retainer away from the loading position toward an unloading position, and moving an end effector in electronic synchronization with advancement of the retainer to the unloading position to synchronize arrival of the retainer at the unloading position with arrival of the end effector at a pick-up position in alignment with the O-ring at the unloading position for pick up of the O-ring by the end effector.
