Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If millimeter wave communications are used to support high data traffic, then communication capacity increases, but signal loss increases due to absorption in high-frequency bands

Engineering Contradiction:

Improvecommunication capacityVSAvoidsignal loss

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent combines a patch antenna and a chip antenna into a single antenna module. The patch antenna provides high gain for millimeter wave communication, while the chip antenna supplements signal transmission in directions where the patch antenna has low radiation efficiency, thereby reducing overall signal loss and improving communication capacity simultaneously

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The antenna module serves multiple functions: the patch antenna handles primary millimeter wave communication, while the chip antenna provides supplementary transmission and reception in directions where the patch antenna is less effective. This multi-functional design allows the system to maintain high communication capacity across multiple directions and frequencies

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a connection member with extended regions is used to accommodate chip antenna, then layout flexibility improves, but device complexity increases

Engineering Contradiction:

Improvelayout flexibilityVSAvoidconnection member structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection member is divided into a first region for mounting the patch antenna and a second region extending farther than the antenna package for mounting the chip antenna. This segmentation allows each region to serve its specific function independently, improving layout flexibility while managing complexity through functional separation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection member extends in a direction different from the lamination direction, utilizing spatial extension in another dimension. This allows the chip antenna to be positioned optimally for omnidirectional performance without increasing the footprint in the primary lamination plane, thereby improving layout flexibility without proportionally increasing overall device complexity

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
