Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical product supply systems are inefficient and costly due to the need for steam sterilization and manual delivery of surgical instruments and implants, lacking flexibility to handle a wide range of surgical procedures and unable to autonomously identify, locate, and manage inventory effectively.
Innovation Solution
A mobile surgical product supply system utilizing RFID technology with radio-reflective and absorptive materials to optimize RFID tag reading, allowing for efficient tracking and management of a large inventory of sterile packaged items, including RFID-tagged surgical items within compartments designed for radio frequency isolation, enabling rapid retrieval and inventory control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical instruments and implants are provided in steam-sterilizable containers requiring autoclaving, then sterilization is achieved, but time and cost efficiency deteriorates due to the sterilization process and manual delivery requirements
Solution Approach 1:
The surgical instruments and implants are pre-sterilized and sealed in sterile containers before delivery to the surgical facility. This preliminary sterilization action eliminates the need for on-site autoclaving, allowing the sterile products to be immediately available for use without time-consuming sterilization processing.
Solution Approach 2:
The manual autoclaving process is replaced with an automated system that uses RFID technology for tracking and robotic mechanisms for automated retrieval and delivery of sterile surgical products. The mechanical autoclave system is substituted with an automated retrieval system that electronically manages sterile inventory.
2Adaptability or versatility
If surgical products are manually delivered and managed, then flexibility in handling various procedures is maintained, but productivity and efficiency deteriorate due to manual processes
Solution Approach 1:
The surgical product supply system is self-managing through automated RFID tracking and robotic retrieval mechanisms. The system automatically tracks inventory levels, identifies required surgical products based on procedure type, and retrieves items without human intervention, eliminating manual delivery processes while maintaining adaptability to different surgical needs.
Solution Approach 2:
The system incorporates RFID tags on surgical products that provide real-time feedback on inventory status, location, and usage. This automated feedback mechanism enables the system to track and manage surgical products efficiently, improving productivity while maintaining the flexibility to handle various surgical procedures through electronic inventory management.
3Reliability
If limited scope sterile kits are used, then specific procedure requirements are met, but adaptability to unforeseen circumstances and wide range of procedures deteriorates
Solution Approach 1:
The surgical product supply system is designed as a universal platform that can accommodate and retrieve any type of sterile surgical product or implant. Rather than using limited scope kits, the system employs a centralized inventory with diverse surgical products, each tagged with RFID, allowing the same automated system to serve multiple surgical procedures and unforeseen requirements.
Solution Approach 2:
The system dynamically adapts to different surgical procedures by using RFID technology to identify and retrieve the specific products needed for each procedure type. The inventory management and retrieval mechanisms are flexible and can be reconfigured electronically to handle various surgical scenarios, from routine procedures to unexpected complications requiring different implants or instruments.
4Adaptability or versatility
If comprehensive inventory of sterile packaged implants and instruments is provided, then wide scope of surgical procedures is supported, but device complexity and autonomous identification requirements increase
Solution Approach 1:
The complex task of manually tracking and identifying surgical products in a comprehensive inventory is replaced with an automated RFID-based system. RFID tags on each product enable automatic identification and tracking, eliminating the need for manual inventory management and reducing the operational complexity despite the large number of surgical products available.
Solution Approach 2:
The system uses RFID tags as electronic copies or digital representations of each surgical product's identity and characteristics. These electronic identifiers allow the automated system to recognize, track, and manage a comprehensive inventory of sterile packaged implants and instruments without requiring complex physical tracking mechanisms, thereby reducing system complexity while supporting wide procedure scope.
