Solution Overview

Problem

The rearrangement and management of peripheral modules in cardiopulmonary bypass systems, such as heart-lung machines, are inefficient due to the complex interweaving of cables and conduits, leading to operational inconvenience and increased downtime during surgical procedures.

Innovation Solution

A cardiopulmonary bypass system with a cable chase that encloses a channel for receiving cables or conduits, featuring apertures for entry and exit at different locations and a reversible cover for access control, allowing for improved routing and management of cables, and attachment to the machine's frame and base for enhanced reconfiguration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If peripheral modules are rearranged or replaced during surgical procedures, then operational flexibility and adaptability are improved, but cable management complexity increases and downtime increases

Engineering Contradiction:
Improveoperational flexibilityVSAvoiddowntime
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system divides the cable management function into separate cable chases associated with each peripheral module. Each cable chase is an independent enclosure that can be accessed, modified, or removed without affecting other modules, enabling quick replacement while maintaining cable organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Cable chases act as intermediary structures between peripheral modules and the main console. These chases provide dedicated pathways and enclosures for cables, serving as mediating elements that facilitate module replacement while managing cable complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple cables and conduits are routed through the system, then connectivity and functionality are improved, but cable clutter and management difficulty increase

Engineering Contradiction:
ImproveconnectivityVSAvoidcable management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable management system is segmented into multiple dedicated cable chases, one for each peripheral module. Each cable chase provides a separate enclosed pathway, preventing cable interweaving and clutter while maintaining all necessary connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Cables and conduits are nested within the enclosed spaces of cable chases. The cable chases themselves are nested within or attached to the peripheral modules and main console structure, creating organized hierarchical routing.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If peripheral modules are quickly replaced, then productivity is improved, but cable routing complexity must be reduced

Engineering Contradiction:
Improvereplacement speedVSAvoidcable routing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

By segmenting cable management into module-specific cable chases, the system enables quick module replacement without requiring complex cable rerouting. Each module's cables remain organized in its own enclosed space, allowing immediate swapout.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Cable chases are pre-configured and pre-routed during system assembly. This preliminary organization of cables before the surgical procedure eliminates the need for complex cable management during module replacement, enabling faster productivity.

Inventive Principle:
Principle #10Preliminary action
