Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If samples are transported open or loosely covered, then access and identification are easy, but contamination and mixing risks increase

Engineering Contradiction:
Improveaccess and identificationVSAvoidcontamination and mixing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention employs a flexible, transparent foil cover that can be easily placed over and removed from the sample receptacle. This thin film provides protective coverage to prevent contamination and mixing while maintaining ease of access and visual identification of the sample contents.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If cap holders are integrated directly on the transport cart, then cap security is improved, but device complexity increases

Engineering Contradiction:
Improvecap securityVSAvoidtransport cart structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cap holder is designed as a separate, modular component that can be independently attached to or removed from the transport cart. This segmentation allows the cap security function to be added without permanently complicating the base transport cart structure, enabling flexible configuration based on specific needs.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple caps are stored on the transport cart, then cap availability is improved, but risk of wrong cap attachment increases

Engineering Contradiction:
Improvecap availabilityVSAvoidcorrect cap matching
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The cap holder incorporates visual identification features such as color coding or labeling that correspond to different sample types and their required caps. This allows operators to quickly and accurately identify the correct cap for each sample, preventing mismatches even when multiple cap types are stored on the transport cart.

Inventive Principle:
Principle #32Color changes
