Multidirectional Tilting Mechanism for Complete Container Draining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tilting mechanisms for filling and draining biopharmaceutical containers are complex, prone to premature failure, limited in directional movement, and costly, making them inefficient and difficult to integrate with standard doorways during the handling of biopharmaceutical compositions.
Innovation Solution
A multidirectional tilting mechanism with a base, tilting deck, and multi-dimensional hinges, actuated by a lifting member, allowing for tilting in multiple directions (up to eight) and featuring a simplified design that fits through standard doorways, with a lifting bag or pneumatic actuator to expand and adjust the tilting deck's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a linear actuator with linkage is used to tilt the platform left or right, then the platform can be tilted in two directions, but the mechanism becomes complex and prone to premature failure
Solution Approach 1:
The tilting mechanism is divided into four independent hinge assemblies positioned at each corner of the platform. Each hinge can independently control tilting in one direction, allowing the system to achieve multi-directional tilting through combination of simple, modular units rather than a complex single actuator system
Solution Approach 2:
The hinge assemblies are designed to be selectively engageable and disengageable, allowing dynamic reconfiguration of the tilting capability. The locking members can engage to lock the platform in a tilted position or disengage to allow return to neutral, providing dynamic control without complex continuous actuators
2Adaptability or versatility
If a linear actuator with linkage is used to tilt the platform, then the platform can be tilted to the right or left, but the mechanism is limited to only two directions
Solution Approach 1:
Four separate hinge assemblies are positioned at each corner of the platform, with each hinge capable of independent operation. This segmentation allows the system to tilt in multiple directions (forward, backward, left, right) by engaging different combinations of hinges, rather than being limited to a single axis of rotation
Solution Approach 2:
Each hinge assembly is designed with universal functionality to handle tilting operations in any direction. The standardized hinge design with globe and receiver components can be engaged in different configurations to achieve various tilting directions, making the system versatile and reliable
3Ease of operation
If a linear actuator is used in the tilting mechanism, then the tilting function is achieved, but the components become cost prohibitive
Solution Approach 1:
The hinge assemblies use simple, inexpensive components such as globes, receivers, and locking members that can be manufactured at low cost. These components are designed to be replaceable if needed, but their simplicity and modularity make them economically viable for standard manufacturing rather than requiring expensive custom actuators
Solution Approach 2:
The expensive linear actuator and linkage system is extracted and replaced with a simpler mechanism using basic mechanical components. The tilting function is achieved through the coordinated action of four independent hinge assemblies with simple locking mechanisms, eliminating the need for costly actuators while maintaining operational capability
4Ease of operation
If the tilting mechanism with FDS is designed with sufficient height for operation, then the tilting function is achieved, but the height prevents passing through a traditional doorway
Solution Approach 1:
The FDS and tilting mechanism are designed as modular, separable components. The FDS can be detached from the tilting mechanism, allowing each component to be transported independently through standard doorways. The modular design enables assembly at the destination while maintaining full operational capability
Solution Approach 2:
The tilting mechanism uses a compact design with hinges that fold or collapse when not in use, reducing the overall height profile. The FDS can be positioned at optimal height for operation during use, but the entire assembly can be configured for low profile during transport through doorways
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables more complete filling and draining of biopharmaceutical compositions by allowing for precise tilting angles (5-45 degrees) in multiple directions, reducing air entrapment, and lowering costs while ensuring the mechanism can pass through standard doorways, thus improving operational efficiency and reducing waste.

AI summary
A tilting mechanism including a base, a tilting deck, four hinges, and a lifting member. Each hinge is positioned adjacent a corner of the base and the tilting deck. Each hinge includes a globe and a receiver with the globe or the receiver secured to the base frame or the deck frame and the other secured to the other of the base or the tilting deck. Each hinge includes a locking member that selectively secures a globe within a respective receiver. The lifting member is secured at a center of the base frame and a center of the deck frame. The lifting member is configured to urge the tilting deck away from the base such that selective engagement allows for tilting of the tilting deck relative to the base in at least four directions.
