Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If guide wires and catheters are looped by hand and clipped or placed on a weighted wet towel, then the wires and catheters can be held in place, but the method is clumsy, inefficient, and prone to droppage and contamination

Engineering Contradiction:

Improveprevention of droppage and contaminationVSAvoidefficiency of wire and catheter handling

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a dedicated wire and catheter holder as an intermediary device between the operator and the medical instruments. This holder provides a secure, controlled environment for storing and retrieving wires and catheters, eliminating the need for manual looping and clipping methods that are prone to error and contamination.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The holder is designed to maintain wires and catheters in a ready-to-use state through its structured compartments and retention mechanisms. The system serves itself by automatically maintaining organization and sterility without requiring continuous manual intervention, thereby improving both reliability and operational efficiency.

Inventive Principle:

Principle #25Self-service

2Area of stationary object

If multiple guide wires and catheters are stored in limited space in the procedure room, then space is utilized, but the wires and catheters are accidentally dropped or contaminated

Engineering Contradiction:

Improvespace utilization in procedure roomVSAvoidrisk of droppage and contamination

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The holder employs a nested structure with multiple levels and compartments that efficiently organize multiple wires and catheters in a compact footprint. Each wire and catheter has its designated space within the holder, preventing them from falling or becoming contaminated while maximizing space utilization in the procedure room.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The holder creates a controlled, sterile environment that protects wires and catheters from contamination. The enclosed design with secure retention mechanisms minimizes exposure to the external environment, effectively reducing the risk of contamination while maintaining compact storage.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

3Ease of operation

If manual looping and clipping methods are used to hold wires and catheters, then the instruments can be retained, but the process is clumsy and inefficient

Engineering Contradiction:

Improveconvenience of wire and catheter retentionVSAvoidprocedural efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The holder is pre-configured with compartments, clips, and retention mechanisms ready to receive and secure wires and catheters. This preliminary preparation eliminates the need for operators to perform manual looping and clipping actions during the procedure, thereby improving both ease of operation and procedural efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the manual mechanical actions of looping and clipping with a structured holder system that provides automatic retention through its design features. This substitution eliminates the clumsiness of manual methods while maintaining secure retention, thereby enhancing both ease of operation and productivity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present invention provides a guide wire and catheter disk holder that carries coiled guide wires and catheters with easy insertion of coiled guide wires and catheters through a side cutout on the holder allowing the user's hand to extend through the disk. The coiled guide wires and catheters are inserted substantially along a plane of the disk thus encouraging uncoiling and expanding of the wires and catheters into a longitudinal channel of the disk. The secured wire can be pulled out of the disk by holding and pulling the entire coiled wire, or by simply pulling the end of the wire while the rest of the wire is still secured inside the holder. Optionally, a spool may be inserted into the disk holder in order to wind up uncoiled wire and catheter within the disk holder.
