Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single support surface is used on the attachment base, then the structure is simple, but the attachment can only fit one specific lid geometry

Engineering Contradiction:

Improvecompatibility with different lid geometriesVSAvoidnumber of support surfaces

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment base is designed with multiple support surfaces (first support surface and second support surface) that can accommodate different lid geometries. This multi-functional design allows the same attachment to work with various lid types without requiring modifications, thereby achieving universality across different kitchen machine variants.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The support structure is segmented into multiple distinct support surfaces rather than a single continuous surface. Each support surface is positioned at a different location and orientation to match specific lid geometries, allowing the attachment to adapt to different lid types through selective engagement of appropriate support surfaces.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple support surfaces are added to accommodate different lids, then versatility improves, but the attachment structure becomes more complex

Engineering Contradiction:

Improvecompatibility with various lid typesVSAvoidstructural complexity of attachment

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple support surfaces and locking surfaces are merged into a single integrated attachment base structure. Rather than using separate components for each support function, the design combines these elements into one unified base that maintains consistent positioning while providing adaptability through its integrated multi-surface geometry.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If the attachment is designed to fit multiple lid geometries, then versatility increases, but maintaining consistent positioning becomes more difficult

Engineering Contradiction:

Improvecompatibility with different lidsVSAvoidconsistent distance from rotating unit

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The attachment base is designed so that despite having multiple support surfaces for different lid geometries, all support surfaces are positioned to maintain the same height and distance relationship to the rotating unit. This equipotential positioning ensures that the attachment operates at a consistent reference level regardless of which lid geometry is being used.

Inventive Principle:

Principle #12Equipotentiality

4Reliability

If frictional connection is used to absorb torque, then the connection is secure, but the attachment may be difficult to install and remove

Engineering Contradiction:

Improvesecure connection and torque absorptionVSAvoidease of installation and removal

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The locking surfaces are designed to provide dynamic frictional engagement that adapts to the applied loads. During normal operation, the frictional connection provides secure torque absorption, while during installation and removal, the same frictional surfaces allow controlled engagement and disengagement through slight rotational movement, making the connection both secure and operationally convenient.

Inventive Principle:

Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables the attachment to be used with multiple lid types without modifications, ensuring stable and secure attachment and consistent positioning for various applications, such as juicing or slicing, while maintaining a fixed distance from the rotating unit.

Implementation Method 1

The locking surfaces primarily serve to create a frictional connection between the lid and the attachment, thus also absorbing torque
