Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pipette-type dispensing means is used to control discharge amount, then dispensing control is improved, but device complexity increases due to multiple components made of different materials

Engineering Contradiction:

Improvedispensing controlVSAvoidnumber of components

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the pipette and cap into a single integral structure called a pipette cap. The cap body and pipette are formed as one piece through injection molding, eliminating the need for separate assembly of multiple components. This reduces device complexity while maintaining the dispensing control function through the integrated design.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple components made of different materials are used, then functional requirements are met, but manufacturing complexity increases

Engineering Contradiction:

Improvefunctional requirementsVSAvoidmanufacturing process

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The cap body and pipette are combined into a single integral component formed by injection molding. This eliminates the need for separate manufacturing and assembly processes for different materials, simplifying production while maintaining all necessary functions through the integrated structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integral pipette cap structure performs multiple functions simultaneously: the cap body provides sealing and pressing functions, while the integrated pipette provides dispensing control. This multi-functional design eliminates the need for separate components, reducing manufacturing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If various materials are used for different components, then performance requirements are satisfied, but environmental friendliness decreases due to difficulty in separation and disposal

Engineering Contradiction:

Improveperformance requirementsVSAvoidenvironmental friendliness

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The entire pipette cap is formed from a single material (polypropylene) through injection molding, creating a homogeneous structure. This eliminates the need to separate different materials for disposal, making the product fully recyclable and environmentally friendly while maintaining all required performance characteristics.

Inventive Principle:

Principle #33Homogeneity
