Solution Overview

Problem

Conventional antenna apparatuses require replacement when changing frequency bands, and they have limited heat discharge efficiency due to integrated electric parts.

Innovation Solution

The antenna apparatus is designed with detachable unit antenna blocks that can be easily switched between single and dual banding, and heat discharge is improved by separating electric parts from the main board and mounting them on heat sinks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If antenna elements are designed for a preset frequency band, then the antenna apparatus can operate at that band, but the entire antenna apparatus needs to be replaced when changing to a different frequency band

Engineering Contradiction:
Improvefrequency band adaptabilityVSAvoidantenna apparatus replacement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The antenna apparatus is divided into separate modular components: a main body and detachable antenna elements. Each antenna element can be independently replaced or swapped based on frequency band requirements, while the main body remains unchanged. This segmentation enables flexible frequency band adaptation without replacing the entire apparatus.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main body of the antenna apparatus is designed with universal interfaces and structures that can accommodate multiple types of antenna elements for different frequency bands. This multi-functionality allows a single main body to support various frequency bands by simply changing the antenna elements, eliminating the need for complete apparatus replacement.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple antennas are installed in one antenna apparatus, then channel capacity increases, but heat discharge efficiency decreases due to integrated electric parts

Engineering Contradiction:
Improvechannel capacityVSAvoidheat discharge efficiency
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

Electric parts are segmented and distributed across multiple antenna elements rather than being integrated in one location. This distribution allows heat to be dispersed across a larger surface area, improving heat discharge efficiency while maintaining multiple antennas for high channel capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a two-dimensional integrated layout to a three-dimensional distributed arrangement of antenna elements and electric parts. By utilizing spatial distribution in multiple dimensions, heat can be dissipated more effectively across the apparatus structure while maintaining the required number of antennas for high productivity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
