Solution Overview
Problem
Current inventory management systems in hospitals, particularly for medical products like sutures, face inefficiencies due to lack of accurate record-keeping, leading to waste, improper restocking, and increased costs, as they rely on manual processes that are time-consuming and prone to errors.
Innovation Solution
A modular shelving system equipped with weight sensors and optical sensors that track the removal and addition of products, transmitting digital signals to a terminal for real-time inventory management, enabling accurate tracking and reducing manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inventory management is used, then device complexity is reduced, but productivity decreases and loss of time increases
Solution Approach 1:
The inventory system performs automatic tracking and monitoring without requiring manual intervention. Weight sensors and optical sensors continuously monitor product inventory levels, and the system automatically generates restocking alerts and manages inventory records, allowing the system to serve itself rather than requiring staff to manually count and track products
Solution Approach 2:
Manual mechanical inventory counting and tracking methods are replaced with an automated electronic system comprising weight sensors, optical sensors, processors, and communication interfaces. The mechanical action of manual counting is substituted with electronic detection and automatic data processing
2Measurement precision
If manual inventory tracking is implemented, then device complexity remains low, but loss of information increases due to estimation errors
Solution Approach 1:
The system continuously monitors inventory levels through weight sensors and optical sensors, providing real-time feedback to the central processor. This feedback loop enables automatic updating of inventory records and generates alerts when products need restocking, ensuring accurate and current inventory information without manual estimation
Solution Approach 2:
Sensors act as intermediaries between the physical products and the digital inventory management system. Weight sensors detect changes in product mass, while optical sensors detect product presence and characteristics, translating physical states into measurable data for accurate tracking
3Reliability
If frequent manual restocking is performed, then inventory availability is maintained, but loss of time increases due to repeated trips to storage areas
Solution Approach 1:
The system performs preliminary monitoring and prediction of inventory needs before actual stockout occurs. By continuously tracking consumption rates and maintaining real-time inventory records, the system can predict when products will need restocking and alert staff in advance, allowing them to prepare and restock during non-critical periods rather than making urgent trips
4Reliability
If excessive inventory is stored to prevent stockouts, then product availability is ensured, but loss of substance increases due to expiration waste
Solution Approach 1:
The system provides continuous feedback on actual consumption rates and inventory levels, enabling dynamic adjustment of restocking quantities. By monitoring usage patterns in real-time, the system can optimize inventory levels to match actual demand, preventing both stockouts and overstocking that leads to expiration waste
Solution Approach 2:
The system dynamically adjusts inventory management parameters such as reorder points and order quantities based on observed consumption patterns and product characteristics. This adaptive approach allows optimization of inventory levels for each product type, maintaining availability while minimizing waste from expiration
