Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of venting caps for disposable cell culture flasks is semi-automatic, leading to extended production time and low productivity due to manual handling, which results in incorrect filter disc placement and defective products.
Innovation Solution
An automated assembly machine with a rotating table, automatic loading, filter disc-sucking, heat-sealing, and unloading mechanisms, along with a lifting platform and guiding rails, ensures precise and efficient placement and bonding of filter discs onto venting caps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling is used to place filter discs, then operation flexibility is maintained, but production time increases and productivity decreases
Solution Approach 1:
The patent replaces manual mechanical operations with an automated mechanical system. A rotating table with multiple positioning fixtures automatically transports venting caps through different stations, and a suction mechanism automatically picks and places filter discs, eliminating manual handling and significantly improving productivity while reducing production time.
Solution Approach 2:
The system enables self-service automation where the machine performs all operations autonomously. The rotating table automatically positions components, the suction mechanism automatically transfers filter discs, and the heat-sealing mechanism automatically bonds components, creating a self-operating production system that eliminates human intervention and maximizes efficiency.
2Manufacturing precision
If manual placement of filter discs is performed, then operational simplicity is maintained, but positioning accuracy decreases leading to defective products
Solution Approach 1:
The patent replaces imprecise manual placement with a precision mechanical system. The rotating table provides exact positioning through multiple fixed fixtures, and the suction mechanism delivers filter discs with consistent accuracy to predetermined locations, ensuring high manufacturing precision and reducing defective products.
Solution Approach 2:
The patent introduces intermediary mechanisms to ensure precision. The rotating table acts as an intermediary transport device with fixed positioning fixtures, and the suction mechanism serves as an intermediary transfer device, both ensuring that filter discs are placed with high accuracy at predetermined positions before heat-sealing.
3Productivity
If semi-automatic production process is used, then equipment complexity is reduced, but production throughput decreases
Solution Approach 1:
The patent segments the production process into distinct functional stations arranged on a rotating table: loading station, filter disc placement station, heat-sealing station, and unloading station. Each station performs a specific operation, and the rotating table coordinates their sequential execution, achieving high throughput through organized modular segmentation.
Solution Approach 2:
The patent merges multiple operations into a single integrated rotating table system. Loading, filter disc placement, heat-sealing, and unloading operations are combined into one continuous automated cycle, allowing simultaneous processing of multiple venting caps and significantly increasing production throughput compared to separate semi-automatic operations.
