Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional print beds are used with fixed configurations, then the bioprinter structure is simple and stable, but the adaptability to different laboratory vessel shapes and functionalities is limited

Engineering Contradiction:
Improveadaptability to different vessel shapesVSAvoidprint bed structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The print bed is divided into a base plate and interchangeable inserts. The base plate provides structural support while the inserts can be swapped to accommodate different vessel shapes and functionalities. This segmentation allows the system to adapt to various laboratory vessels without redesigning the entire print bed structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular print bed system serves multiple functions through interchangeable inserts that can be configured for different vessel types (petri dishes, well plates, custom dishes). The same base plate structure supports various inserts, making the bioprinter versatile for different applications without requiring multiple dedicated print beds.

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

2Adaptability or versatility

If conventional fixed print beds are used, then the device is easier to operate, but the functionality is limited to what was initially designed

Engineering Contradiction:
Improvefunctionality alteration capabilityVSAvoidoperational simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The print bed transitions from a static fixed configuration to a dynamic modular system where inserts can be exchanged based on printing requirements. This dynamic capability allows functionality to be altered by swapping inserts while maintaining ease of operation through simple insertion and removal mechanisms that do not require complex tools or procedures.

Inventive Principle:
Principle #15Dynamics

3Reliability

If conventional print beds accommodate specific standardized vessel shapes, then the print bed structure is simple, but the retention and heat distribution are poor

Engineering Contradiction:
Improveretention and heat distributionVSAvoidprint bed configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Different inserts are designed with specific local qualities optimized for their intended vessel types. Each insert has tailored retention features and thermal properties suited to the particular vessel shape it accommodates, improving overall retention and heat distribution without requiring a completely different print bed structure for each application.

Inventive Principle:
Principle #3Local quality
