Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If antenna modules are disposed at a corner of the portable electric device to save inner space, then the space utilization is improved, but the number of antenna radiation directions is limited

Engineering Contradiction:

Improvecorner space utilizationVSAvoidantenna radiation directions

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The flexible substrate is divided into multiple bent portions (first bent portion, second bent portion, third bent portion) that can be independently configured to different angles, allowing each segment to radiate in different directions while occupying corner space

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bent portions of the flexible substrate are designed to be adjustable in angle, enabling dynamic reconfiguration of antenna radiation directions to adapt to different communication needs while maintaining compact corner placement

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple antenna circuits are integrated on the flexible substrate to provide multiple radiation directions, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:

Improveantenna radiation directionsVSAvoidantenna module structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The flexible substrate serves multiple functions simultaneously: it acts as the structural support, the mounting platform for antenna circuits, and the radiation element itself through its bent portions, eliminating the need for separate support structures for each antenna

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple antenna circuits are integrated on the same flexible substrate with shared bent portions, merging what would traditionally be separate antenna assemblies into a single unified structure that provides multiple radiation directions

Inventive Principle:

Principle #5Merging (Combining)
