Solution Overview

Problem

Existing stamped and bent parts for conducting electrical currents or shielding face challenges in occupying minimal space and maintaining robustness due to anisotropic grain structures from manufacturing processes, which affect bending properties and space-saving designs.

Innovation Solution

A stamped and bent part with a plate-shaped section and a pin section projecting from it, where the pin section is bent about a perpendicular axis to the main grain direction, allowing for space-efficient insertion and robust connection, utilizing a rolling process to create a line-like texture indicating the grain direction for precise forming and bending.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the pin section is bent parallel to the main grain direction, then the bending process is easier, but the bending radius is large and space is not saved

Engineering Contradiction:

Improvebending process easeVSAvoidspace occupation

Core Design Contradiction:

Ease of manufactureVSVolume of moving object

Solution Approach 1:

The patent changes the bending direction parameter from parallel to perpendicular relative to the main grain direction. This parameter change enables achieving small bending radii and space-saving configurations while maintaining manufacturing feasibility through the specific orientation relationship between the bending axis and grain structure

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces a new dimensional orientation for bending by bending the pin section perpendicular to the main grain direction rather than parallel to it. This dimensional change in bending orientation allows achieving compact geometries with small bending radii that were not possible with conventional bending directions

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Volume of moving object

If the pin section is bent perpendicular to the main grain direction, then space is saved with small bending radii, but the bending process becomes more difficult

Engineering Contradiction:

Improvespace occupationVSAvoidbending process difficulty

Core Design Contradiction:

Volume of moving objectVSEase of manufacture

Solution Approach 1:

The patent optimizes the bending parameter by selecting a specific orientation (perpendicular to main grain direction) that balances manufacturing difficulty with space-saving benefits. This parameter optimization allows achieving compact geometries while keeping the bending process within acceptable manufacturing limits

Inventive Principle:

Principle #35Parameter changes

3Volume of moving object

If the stamped and bent part is designed for compact insertion, then space is saved, but the connection robustness may be compromised

Engineering Contradiction:

Improveinsertion spaceVSAvoidconnection robustness

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent applies different quality characteristics to different parts: the pin section is bent perpendicular to the grain direction to achieve compact local geometry for space-saving insertion, while the plate-shaped section maintains its grain structure for overall structural robustness. This local differentiation allows both compactness and reliability
