Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Adaptability or versatility
If cable adapters are used to accommodate round cross-section contact pins, then connector compatibility is improved, but installation space increases
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.
3Productivity
If contact elements are made from stamped grids, then manufacturing efficiency is improved, but contact geometry flexibility deteriorates
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.
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.

Function Achieved in This Case
Enables a compact, robust, and easily handled assembly that maintains electrical contact under operational conditions, accommodating various connector configurations without increasing installation space.
Implementation Method 1
the contact elements of the contact adapter are elastically deformed by the contact elements of the connector within the spring section. This is intended to ensure a robust electrical contact between the contact adapter and the connector, even under operational vibrations or thermal expansion.
