Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional T-shaped shield development is used with progressive processing, then the anti-noise shielding function is provided, but the process takt time is long and material cost is high

Engineering Contradiction:

Improveprocess takt timeVSAvoidfeed takt time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The shield development is segmented into multiple portions (first shield portion, second shield portion, third shield portion A, third shield portion B, fourth shield portion) with specific adjacency relationships. This segmentation allows for optimized stamping sequences and reduced feed pitch, improving productivity while maintaining shielding effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shield development transitions from a conventional T-shape to a multi-dimensional configuration where the third shield portion is divided into A and B sections with specific spatial relationships. This dimensional reorganization enables shorter feed pitch in progressive processing by optimizing the layout in both horizontal and vertical dimensions.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If a conventional T-shaped shield development is used with progressive processing, then the anti-noise shielding function is provided, but material cost is high

Engineering Contradiction:

Improvematerial utilizationVSAvoidmaterial usage

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The third shield portion is merged into two contiguous sections (A and B) that are strategically positioned to maintain electrical continuity while reducing overall material consumption. The merging of functional requirements into a reorganized structure reduces material waste.

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If conventional shield portions are used, then basic shielding is provided, but conduction paths for noise reduction are insufficient

Engineering Contradiction:

Improvenoise shieldingVSAvoidanti-noise shielding function

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

Conduction path portions are pre-formed during the stamping process to establish electrical continuity between shield portions before final assembly. This preliminary action ensures reliable noise shielding by pre-establishing ground paths.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Conduction path portions act as intermediaries that electrically connect adjacent shield portions (first, second, third A, third B, and fourth portions). These intermediary elements ensure continuous electrical grounding across the entire shield structure, enhancing noise shielding reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)
