Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a modular design with separate contact elements and housing components is used, then assembly flexibility and manufacturing efficiency are improved, but the number of separate parts increases device complexity

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidnumber of parts
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The electrical plug connector is divided into modular components: a housing (10) with integrated insulation, separate contact elements (20, 30) that can be independently manufactured and assembled, and a common insulating body. This segmentation allows each component to be optimized and manufactured separately using appropriate processes, then assembled into the final product, improving manufacturing efficiency while maintaining manageable complexity through functional grouping.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines multiple functions into integrated components: the housing (10) integrates structural support, insulation, and contact element retention; the common insulating body houses multiple contact elements and provides electrical isolation. This merging reduces the number of separate parts needed compared to fully discrete designs while preserving manufacturing flexibility through modular assembly of these integrated units.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If contact elements are designed with flexible portions for engagement, then connection reliability is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidflexible portion geometry
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The contact elements utilize elastic deformation as a design parameter, where flexible portions are engineered to bend and return to their original shape. This elastic behavior provides self-adjusting engagement that compensates for minor dimensional variations, achieving reliable connections without requiring extremely tight manufacturing tolerances. The material selection and cross-sectional geometry are optimized to provide appropriate flexibility and recovery force.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The flexible portions of the contact elements perform self-alignment and self-adjustment during assembly through elastic deformation. As contacts are inserted, the flexible portions automatically bend to accommodate slight misalignments and then return to their predetermined positions, creating reliable electrical connections without requiring precision alignment fixtures or complex adjustment mechanisms.

Inventive Principle:
Principle #25Self-service

3Reliability

If separate common insulating bodies are used for different contact element groups, then electrical isolation is improved, but device complexity and assembly steps increase

Engineering Contradiction:
Improveelectrical isolationVSAvoidinsulating body structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple insulating functions into a single integrated common insulating body that houses both the first contact elements and second contact elements. This unified insulating structure provides electrical isolation between different contact groups while reducing the total number of insulating components compared to using separate insulating bodies for each contact group, thereby simplifying assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Within the common insulating body, distinct compartments or regions are created to separate different contact element groups, maintaining electrical isolation through physical segmentation. The insulating material itself is segmented into regions that provide isolation, allowing multiple contact elements to coexist in one housing without electrical interference while keeping the overall structure unified.

Inventive Principle:
Principle #1Segmentation
