Solution Overview

Problem

Existing connection arrangements on printed circuit boards face challenges in efficiently accommodating differently configured connectors without reconfiguring the contact elements, particularly when using stamped grids and round cross-section contact pins, necessitating the use of cable adapters.

Innovation Solution

A contact adapter with a carrier plate and configurable contact elements, designed for integration into connectors, allows for flexible interfacing between circuit boards and connectors, using metallic stamped and bent parts with optional spring sections for robust electrical contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cable adapters are used to mediate between differently configured connectors, then connector configurability is improved, but device complexity and installation space increase

Engineering Contradiction:
Improveconnector configurabilityVSAvoidconnection arrangement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The contact adapter merges the functions of multiple contact elements with different geometries into a single integrated component. The carrier plate combines stamped grid contacts and round cross-section contacts in one structure, eliminating the need for separate cable adapters and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The contact adapter serves multiple functions simultaneously: it provides electrical connections for both stamped grid contacts and round cross-section contacts, acts as a mechanical interface between different connector types, and enables configurability without requiring separate adapter components for each contact geometry.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If cable adapters are used to accommodate round cross-section contact pins, then connector compatibility is improved, but installation space increases

Engineering Contradiction:
Improveconnector compatibilityVSAvoidinstallation space
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The contact elements are nested within the carrier plate structure. The stamped grid contacts and round cross-section contacts are integrated into the same carrier plate, allowing them to occupy the same spatial envelope and eliminating the need for additional external adapter components.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If contact elements are made from stamped grids, then manufacturing efficiency is improved, but contact geometry flexibility deteriorates

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidcontact geometry flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The contact adapter segments different contact geometries into distinct contact elements that are then integrated into a single carrier plate. This allows each contact element to be optimized for its specific geometry (stamped grid or round cross-section) while maintaining manufacturing efficiency through standardized production methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The contact adapter uses a composite structure combining different contact element types (stamped grid contacts and round cross-section contacts) within a single carrier plate, enabling both manufacturing efficiency and geometric flexibility to coexist.

Inventive Principle:
Principle #40Composite materials
