Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If signal terminals and grounding terminals are placed discretely with larger spaces, then each terminal can be independently connected, but wires need to traverse multiple terminals resulting in difficult wire arrangement and poor cross-talk shielding

Engineering Contradiction:

ImproveIndependent terminal connectionVSAvoidWire arrangement complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges signal terminals and grounding terminals into a closely integrated array where they are positioned adjacent to each other rather than discretely separated. This allows wires to connect directly to nearby terminals without traversing large spaces, simplifying wire arrangement while maintaining independent terminal connectivity through the compact terminal layout

Inventive Principle:

Principle #5Merging (Combining)

2Ease of manufacture

If signal terminals and grounding terminals are placed discretely with larger spaces, then each terminal can be independently connected, but cross-talk shielding between grounding terminals deteriorates

Engineering Contradiction:

ImproveIndependent terminal connectionVSAvoidCross-talk interference

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent utilizes the connecting bar extending in a direction substantially perpendicular to the terminal array direction, creating a three-dimensional connection path. This dimensional change allows the wire to bypass the terminal array plane and establish direct connections without traversing across multiple terminals in the same plane, thereby improving cross-talk shielding while maintaining manufacturing ease

Inventive Principle:

Core Design Contradiction:

Ease of manufactureVSLength of moving object

Solution Approach 1:

The patent utilizes the connecting bar extending in a direction substantially perpendicular to the terminal array direction, creating a three-dimensional connection path. This dimensional change allows the wire to bypass the terminal array plane and establish direct connections without traversing across multiple terminals in the same plane, thereby reducing wire path length while maintaining terminal independence through the structured terminal array
