Solution Overview

Problem

Existing technologies face challenges in creating a space-saving and easy-to-manufacture contact element for conducting electrical currents or shielding that can be efficiently connected to circuit boards.

Innovation Solution

A stamped and bent part with a plate-shaped section and a pin section that projects perpendicularly to the main grain direction, allowing for a stable connection and easy integration with circuit boards, utilizing a bending axis parallel to the surface normal of the plate-shaped section.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the pin section is bent about a bending axis perpendicular to the main grain direction, then the bending process becomes easier and more reliable, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvebending processVSAvoidmanufacturing process
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent changes the orientation parameter of the bending axis relative to the main grain direction. By specifying that the bending axis is perpendicular to the main grain direction, the patent optimizes the bending process for easier and more reliable formation while accepting the need for precise alignment in manufacturing

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent performs the bending operation as a preliminary action during the stamping and bending process itself, rather than as a separate subsequent operation. This integrates the bending into the primary manufacturing flow, reducing the need for additional complex equipment

Inventive Principle:
Principle #10Preliminary action

2Volume of moving object

If the stamped and bent part lies in one plane with the pin section, then space is saved for insertion into housing, but the connection stability to circuit board may be compromised

Engineering Contradiction:
Improveinsertion spaceVSAvoidconnection stability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent utilizes the third dimension by bending the pin section perpendicular to the main grain direction, which creates an out-of-plane configuration that provides both space efficiency for insertion and adequate connection stability through the bent geometry

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

Solution Approach 2:

The patent creates an asymmetric configuration where the pin section is bent at a specific angle relative to the plate-shaped section, with the bending axis perpendicular to the main grain direction. This asymmetric bending provides both compactness for space-saving insertion and mechanical stability for reliable connection

Inventive Principle:
Principle #4Asymmetry
