Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current freeze-drying systems require inflexible rail-guided transfer cars, leading to longer loading times and difficulties in adapting to system expansions, while maintaining clean room conditions is challenging, especially when maintaining or modifying the transfer device.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rail-guided transfer car is used, then the transfer path is predetermined and stable, but the system lacks flexibility when expanding or supplementing the freeze-drying system
Solution Approach 1:
The transfer device is divided into a detachable lifting carriage and a support frame. The lifting carriage can be separated from the support frame, allowing independent maintenance, cleaning, and sterilization of components without disrupting the entire system. This segmentation enables flexible system expansion and modification.
Solution Approach 2:
The transfer device replaces the fixed rail system with a mobile lifting carriage that can be freely positioned and maneuvered. The lifting carriage can be driven to different locations and lifted to adjust heights, providing dynamic adaptability for system expansion and reconfiguration without requiring permanent rail infrastructure.
2Productivity
If the transfer car moves on a fixed rail route, then the path is predetermined, but loading times are extended and system adaptability is reduced
Solution Approach 1:
The lifting carriage and support frame are detachable, allowing the lifting carriage to be separated for rapid maintenance, cleaning, and sterilization. This reduces downtime and allows these activities to occur independently without moving the entire transfer device or disrupting freeze-drying operations.
Solution Approach 2:
A detachable coupling device connects the lifting carriage to the support frame, enabling quick attachment and detachment. This intermediary mechanism facilitates rapid reconfiguration and maintenance operations, minimizing time losses while maintaining operational efficiency.
3Reliability
If the laminar flow device operates continuously to maintain clean room conditions, then contamination is prevented, but energy consumption increases
Solution Approach 1:
The detachable coupling device allows the laminar flow device to be quickly disconnected from the support frame. This enables the laminar flow device to be moved to a separate area for maintenance, cleaning, or sterilization without transporting the entire support frame, reducing energy consumption during these operations while maintaining clean room conditions during active use.
