Modular Tablet Dispensing Interface for Fast Blister Format Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tablet dispensing systems require extensive reconfiguration and multiple heavy equipment changes when switching between different tablet formats or types, leading to inefficiencies in filling blister pockets, particularly for elongated or complex shapes, and pose challenges in maintaining cleanliness and flexibility.
Innovation Solution
A reconfigurable device with a modular frame and interchangeable dispensing accessories, featuring a removable interface with drive members and adjustable attachment points, allowing for quick setup and tool-free operation, reducing equipment size and complexity, and enabling easy integration with various blister packaging machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple specific heavy equipment are used for different tablet formats, then optimal filling for each format is achieved, but the complexity of equipment changes and assembly-disassembly operations increases significantly
Solution Approach 1:
The patent implements a universal dispensing platform that can accommodate multiple tablet formats through interchangeable modules. The base unit remains constant while format-specific accessories attach to the front, allowing one piece of equipment to perform multiple functions for different tablet shapes and sizes, thereby reducing the need for multiple heavy equipment pieces.
Solution Approach 2:
The dispensing equipment is divided into a permanent base structure and removable front accessories. This segmentation allows the complex format-specific components to be separated from the main unit, enabling quick attachment and detachment without reconfiguring the entire system, thus reducing assembly-disassembly complexity.
2Manufacturing precision
If multiple specific heavy equipment are used for different tablet formats, then optimal filling for each format is achieved, but the time required for assembly-disassembly operations increases
Solution Approach 1:
By segmenting the equipment into a permanent base and removable front accessories, the system enables quick changes without reconfiguring the entire dispensing unit. Only the front portion needs to be attached or detached, significantly reducing the time required for format changes compared to reconfiguring heavy equipment.
Solution Approach 2:
The accessories are designed to be pre-configured for specific tablet formats before attachment. This preliminary preparation allows operators to simply attach the appropriate pre-configured module rather than configuring components during format changes, reducing reconfiguration time.
3Manufacturing precision
If multiple specific heavy equipment are used for different tablet formats, then optimal filling for each format is achieved, but productivity is reduced due to shutdown of packaging
Solution Approach 1:
The segmented design allows format changes without shutting down the entire packaging line. Only the front accessory module needs to be changed while the base unit and packaging operations continue, minimizing productivity loss during format transitions.
Solution Approach 2:
The system transitions from static heavy equipment requiring full shutdown for reconfiguration to a dynamic modular system where accessories can be quickly swapped. This dynamic approach maintains continuous packaging operations while adapting to different tablet formats, preserving productivity.
4Adaptability or versatility
If a reconfigurable device with interchangeable accessories is used, then flexibility and ease of operation are improved, but the device size and integration difficulty increase
Solution Approach 1:
The accessories are designed to attach to the front of the base unit in a nested configuration, where the removable module integrates with the existing structure rather than adding significant external dimensions. This nesting approach maintains a compact overall device size while providing format versatility.
5Stability of the object's composition
If actuators and attachment points are fixed in position, then structural stability is maintained, but the ability to use new dispensing solutions is limited
Solution Approach 1:
The system separates the fixed base structure with stable attachment points from the removable front accessories. This segmentation allows the base to maintain structural integrity while the accessories provide dispensing versatility, as each accessory can be designed for specific dispensing configurations without compromising base stability.
6Adaptability or versatility
If multiple actuators and attachment points are present, then multiple dispensing configurations are supported, but cleaning difficulty increases
Solution Approach 1:
By concentrating the actuators and attachment points in the permanent base unit while making the front accessories removable, the system allows the complex multi-actuator portion to be easily detached for cleaning. The removable accessory can be cleaned separately or replaced, simplifying maintenance while maintaining dispensing versatility.
