Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If automated dispensing robots are used to improve accuracy and efficiency, then medication distribution accuracy is improved, but system reliability deteriorates due to susceptibility to electro-mechanical failures
Solution Approach 1:
The system divides the automated dispensing function into multiple independent robotic units, each capable of autonomous operation. This segmentation ensures that a failure in one unit does not compromise the entire system, as other units can continue operating or serve as backups.
Solution Approach 2:
The patent transitions from mechanical articulated arms to wireless autonomous robotic units with different operational parameters. These robotic units use alternative locomotion and dispensing mechanisms that are less susceptible to traditional electro-mechanical failures, changing the system's reliability characteristics.
2Device complexity
If a small number of robotic arms are used to store and retrieve medications, then device complexity is reduced, but productivity deteriorates due to inability to service large concurrent volume
Solution Approach 1:
Instead of using a few complex robotic arms, the system employs multiple simpler autonomous robotic units. Each unit is relatively simple in design but the collective system achieves high throughput through parallel operation of many units simultaneously servicing different medication stations.
Solution Approach 2:
The system moves from a centralized vertical robotic arm architecture to a distributed horizontal network of autonomous units. This dimensional shift allows concurrent medication distribution across multiple locations simultaneously, dramatically increasing productivity without proportionally increasing individual unit complexity.
3Adaptability or versatility
If manual medication picking tasks are performed to maintain operational flexibility, then adaptability is improved, but manufacturing precision deteriorates due to human error in picking and storage
Solution Approach 1:
The autonomous robotic units are equipped with onboard identification and verification systems that enable them to independently locate, pick, and verify medications without human intervention. This self-service capability eliminates human error in medication picking while maintaining the flexibility to adapt to different medication types and locations.
Solution Approach 2:
The system incorporates verification mechanisms where robotic units scan and confirm medication identities before dispensing. This feedback loop ensures high precision in medication picking and storage, with the system able to detect and correct errors automatically while adapting to various medication configurations.
