Solution Overview

Problem

Existing bioprocessing systems face challenges in securely managing flexible tubing, including tangling, snagging, and accidental disassembly, particularly with tubes of different diameters, which can lead to operational inefficiencies and complexity.

Innovation Solution

The development of a tube retainer system comprising a block structure with male and female connectors and a mounting bar, allowing for secure interlocking and management of tubing through a tube slot and annular opening configuration, which accommodates various diameters and reduces the risk of tangling and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional tube management methods are used, then tubes can be freely routed, but tubes become tangled and prone to snagging

Engineering Contradiction:
Improvetube routing flexibilityVSAvoidtube tangling and snagging risk
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The tube retainer block is divided into multiple independent tube slots, each capable of holding individual tubes separately. This segmentation allows tubes to be organized in discrete positions rather than freely routed, preventing tangling while maintaining easy access and installation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If tubes of different diameters are managed separately, then each tube type requires dedicated management, but this increases system complexity

Engineering Contradiction:
Improvetube management securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The tube retainer block incorporates multiple tube slots that can accommodate tubes of different diameters within a single unified structure. The block design allows different slots to hold different tube types simultaneously, eliminating the need for separate management systems for each tube diameter while maintaining secure holding through the common block structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If tube retainers are designed with interlocking connectors, then accidental disassembly is prevented, but the assembly process becomes more complex

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The male and female connectors are integrated directly into the tube retainer block structure itself, merging the connector functions with the retainer body. This combination eliminates the need for separate connector components and simplifies the assembly process, while the interlocking design between male and female connectors still provides reliable prevention of accidental disassembly.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If a comprehensive tube management system is implemented, then tube security is improved, but the device size and design complexity increase

Engineering Contradiction:
Improvetube securityVSAvoiddesign complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple tube slots, connectors, and retention features are merged into a single integrated tube retainer block structure. This consolidation provides comprehensive tube security through multiple functional elements while reducing overall design complexity by eliminating the need for separate components and assemblies.

Inventive Principle:
Principle #5Merging (Combining)
