Problem

Existing Distributed Antenna Systems (DAS) require multiple separate modules that need to be interconnected by experienced installers, leading to cumbersome and inefficient installations that are not compliant with federal, municipal, and technical requirements.

Innovation Solution

A unified, integrated bi-directional RF amplifier system with an internal power source, including a power amplifier, RF signal filter, and backup power source within a single housing, reducing the need for external connections and simplifying installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If multiple separate modules are used in DAS systems, then system functionality is achieved, but installation complexity and time increase

Engineering Contradiction:

Improvesystem functionalityVSAvoidinstallation time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The patent combines multiple separate DAS modules (power amplifier, RF signal filter, backup power source) into a single integrated housing. This merging eliminates the need for multiple interconnections and reduces installation complexity while maintaining all required system functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated housing serves multiple functions simultaneously: it provides structural enclosure, houses the power amplifier, contains the RF signal filter, and accommodates the backup power source. This multi-functionality reduces the number of separate components needed and simplifies installation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate modules are interconnected, then system requirements are met, but installer expertise requirements increase

Engineering Contradiction:

Improvecompliance with requirementsVSAvoidinstaller expertise

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

By integrating all modules into a single pre-configured unit, the patent eliminates complex interconnections that require skilled installers. The unified system maintains compliance with federal, municipal, and technical requirements while reducing installation to simple plug-and-play connectivity.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If multiple separate modules are used, then system functionality is achieved, but number of installers required increases

Engineering Contradiction:

Improvesystem functionalityVSAvoidinstallation efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent merges multiple functional modules into a single integrated unit, allowing one installer to complete the installation instead of requiring multiple specialists. This maintains full system functionality while dramatically improving installation productivity.

Inventive Principle:

Principle #5Merging (Combining)

4Ease of operation

If modules are integrated into single housing, then installation is simplified, but internal space constraints increase

Engineering Contradiction:

Improveinstallation easeVSAvoidinternal space

Core Design Contradiction:

Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent nests multiple modules within a single housing structure, with each component (power amplifier, RF filter, backup power source) contained within the unified enclosure. This nesting approach simplifies installation by reducing the number of external connections while efficiently utilizing internal space.

Inventive Principle:

Principle #7Nested doll (Nesting)
