Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the tube assembly is attached to the cell processing device, then the production automation is improved, but the tube assembly becomes entangled and handling becomes complicated

Engineering Contradiction:
Improveproduction automationVSAvoidhandling of tube assembly
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The panel is divided into multiple groove portions (first groove portion for tube insertion, second groove portion for positioning) that separately manage different aspects of tube assembly handling. This segmentation allows the tube to be guided through specific paths while maintaining organization and preventing entanglement during automated operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The panel acts as an intermediary component between the tube assembly and the cell processing device. The grooves on the panel provide a structured interface that guides tube insertion and positioning, facilitating automated attachment while preventing entanglement through controlled geometry.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the tube is fixed to the panel, then the mountability is improved, but the tube protrudes out of the panel surface causing entanglement or separation

Engineering Contradiction:
ImprovemountabilityVSAvoidtube entanglement and separation risk
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The tube is nested within the groove structure of the panel. The first groove portion receives and secures the tube, while the second groove portion provides additional positioning. This nesting approach keeps the tube contained within the panel boundaries, preventing protrusion-related entanglement while maintaining secure fixation.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The panel uses a flexible resin material that can accommodate the tube within its groove structure. The flexibility of the resin panel allows it to conform to the tube while maintaining the groove geometry that prevents protrusion, balancing secure fixation with prevention of entanglement.

Inventive Principle:
Principle #30Flexible shells and thin films

3Productivity

If the tube assembly is frequently attached and detached for single-use operation, then the regenerative medicine production efficiency is improved, but the risk of work mistakes increases due to difficulty in visualizing attachment state

Engineering Contradiction:
Improveproduction efficiencyVSAvoidattachment accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The resin panel utilizes light transmittance properties to provide visual indication of the attachment state. The transparent or translucent nature of the resin panel allows operators to visually confirm proper tube insertion and positioning during frequent attachment and detachment operations, reducing work mistakes while maintaining high productivity.

Inventive Principle:
Principle #32Color changes

4Weight of moving object

If the resin panel is made thin to reduce weight, then the device portability is improved, but the structural strength decreases

Engineering Contradiction:
Improvepanel weightVSAvoidpanel structural strength
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The panel incorporates multiple groove portions that segment the structural load paths. These grooves are strategically positioned to maintain structural integrity while minimizing material usage, allowing the panel to remain thin and lightweight while retaining sufficient strength for tube fixation and device operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The resin panel exhibits local quality variations through the groove portions that concentrate structural strength where needed (at tube insertion points) while maintaining thin overall thickness. The grooves create localized reinforcement zones that provide necessary strength without requiring the entire panel to be thick, thus reducing overall weight.

Inventive Principle:
Principle #3Local quality
