Compartmentalized Drying Rack for Instrument Set Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying rack devices for dental, medical, and veterinary instruments result in inefficiencies and increased risk of injury and pathogen exposure due to loose instruments mixing, rewetting, and the need for manual sorting, which slows the sterilization process and increases the risk of damage.
Innovation Solution
A compartmentalized countertop drying rack with drain holes and a water collection tray that organizes instruments, allowing them to air dry while preventing cross-contamination and injury, featuring optional fans and heating elements for enhanced drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If instruments are dumped from ultrasonic cleaner into a pile to dry, then instruments can be dried, but instruments become mixed up and require manual sorting which slows the sterilization process
Solution Approach 1:
The drying rack is divided into multiple compartments that correspond to different instrument sets. Instruments are placed in designated compartments based on their set assignment, preventing mixing and eliminating the need for manual sorting. Each compartment acts as a separate drying zone for specific instrument groups.
2Ease of operation
If loose instruments are handled for sorting, then instruments can be organized into sets, but users risk being poked, cut, and exposed to bloodborne pathogens
Solution Approach 1:
Instruments are assigned to specific compartments before the drying process begins. This preliminary organization based on instrument set designation allows instruments to dry in their final designated positions without requiring subsequent handling for sorting, thereby eliminating exposure risks during the drying phase.
3Productivity
If instrument tips are handled during sorting, then instruments can be organized, but instrument tips can be easily damaged
Solution Approach 1:
Instruments are placed in their final compartment destinations before drying begins, based on pre-determined set assignments. This eliminates subsequent handling and manipulation of instrument tips during the drying process, preventing damage to delicate tips while maintaining organization efficiency.
4Area of stationary object
If cassettes are piled on top of each other to dry, then space is saved, but instruments rewet and the sterilization process is slowed
Solution Approach 1:
The drying rack uses vertically stacked compartments with separate drainage pathways for each level. Instruments in upper compartments dry independently from those below, preventing cross-contamination and rewetting. Each compartment functions as an isolated drying chamber, allowing compact vertical arrangement without compromising drying effectiveness.
5Productivity
If a compartmentalized drying rack with drain holes is used, then instruments stay organized and dry efficiently, but the device complexity increases
Solution Approach 1:
The drying rack integrates multiple functions into a single device: compartmentalization for organization, drain holes for water removal, and tray collection for runoff management. This multi-functionality achieves efficient drying and organization without requiring separate devices for each function, balancing complexity with performance benefits.

AI summary
The present invention relates to a novel drying rack device. The device is designed to save time and effort when cleaning and sterilizing instruments, cassettes, tools, and/or accessories. The device comprises a countertop drying rack that sits on a tray. The countertop drying rack comprises a plurality of compartments that can be round and/or flat, with a plurality of drain holes for air drying wet instruments. Further, the tray below the rack collects water runoff for safe disposal and to allow the instruments to air dry. The device keeps instruments and tools organized, different kits separated, allows instruments to dry, and decreases risk of injury and exposure to bloodborne pathogens.
