Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a coding system uses multiple interchangeable parts to modify connector compatibility, then adaptability is improved, but device complexity increases and ease of operation deteriorates

Engineering Contradiction:
Improveconnector compatibilityVSAvoidnumber of interchangeable parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the coding system adjustable through rotation. The first and second parts can be rotated to different angular positions around the connection axis, dynamically changing the alignment between protrusions and recesses. This allows the same physical components to provide different coding configurations without requiring multiple interchangeable parts, thus improving adaptability while reducing device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the coding function into two independent rotatable components (first part on first connector, second part on second connector). Each part has its own protrusions that can be independently positioned. This segmentation allows flexible combination of coding patterns while using a single set of standardized parts, reducing the need for multiple interchangeable components

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a coding system uses multiple interchangeable parts to modify connector compatibility, then adaptability is improved, but ease of operation worsens due to risk of misplacement

Engineering Contradiction:
Improveconnector compatibilityVSAvoidmodification simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The dynamic rotation mechanism allows users to easily reconfigure connector compatibility by simply rotating parts to desired angular positions. The locking mechanism secures the parts in place once positioned, eliminating the risk of misplacement during operation. This provides both adaptability and ease of operation without requiring multiple interchangeable parts that could be misplaced

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If a coding system uses fixed machined surfaces, then manufacturing precision is improved, but adaptability deteriorates

Engineering Contradiction:
Improvecoding system precisionVSAvoidconnector compatibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent maintains manufacturing precision through precisely machined protrusions and recesses on the rotatable parts. However, it overcomes the fixed nature of traditional coding systems by allowing these precisely manufactured features to be positioned at different angular orientations through rotation. This combines the precision of fixed machined surfaces with the adaptability of adjustable positioning

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent adds the angular dimension to the traditional linear coding system. Instead of only providing fixed coding positions along a linear path, the rotatable parts introduce rotational freedom, allowing protrusions and recesses to align at multiple angular positions. This dimensional expansion provides adaptability while maintaining the precision of machined features

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
