Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If digital radio interface modules with digital to analogue conversion circuits are integrated into existing dual band radio control room communications systems, then the systems can communicate with various digital and analogue radios through a single operator interface, but the device complexity increases

Engineering Contradiction:
Improvecompatibility with digital radio standardsVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces digital radio interface modules (DRIMs) as intermediary components between the existing dual band radio system and new digital radio standards (TETRA, DMR, Marine VHF). These DRIMs contain digital to analogue conversion circuits that translate digital radio signals into analogue format, enabling the legacy system to communicate with digital radios through the existing analogue interface without requiring complete system replacement.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The control room system is enhanced with multi-functional capability to handle both traditional analogue dual band radios and multiple digital radio standards simultaneously. The DCIM software application provides a unified operator interface that can patch and route communications from various radio types (analogue, TETRA, DMR, Marine VHF) through a single console, making the system universal in its communication capabilities.

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

2Adaptability or versatility

If existing dual band radio control room communications systems are upgraded to support new digital radio standards, then communication capability with digital radios is enabled, but the cost increases significantly

Engineering Contradiction:
Improvesupport for digital radio standardsVSAvoidcost
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The upgrade path is segmented into modular digital radio interface modules (DRIMs) that can be added incrementally to the existing system. Rather than replacing the entire control room system, the solution divides the upgrade into separate functional modules (supporting TETRA, DMR, Marine VHF) that can be integrated one at a time, allowing phased investment and reducing overall cost.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates interface modules that replicate the functionality of native digital radio interfaces within the legacy analogue system. The DCIM software application copies and adapts the control and patching mechanisms from traditional dual band radio operations to work with digital radio standards, allowing the system to emulate familiar operations while supporting new radio types.

Inventive Principle:
Principle #26Copying

3Productivity

If digital radio interface modules are added to enable communication with multiple radio standards, then operational efficiency is enhanced, but the ease of operation decreases due to additional configuration requirements

Engineering Contradiction:
Improveoperational efficiencyVSAvoidconfiguration complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The DCIM software application incorporates self-configuration capabilities that automatically detect and adapt to the connected radio interface modules. The system performs automatic radio type identification and configures appropriate communication parameters without requiring manual intervention for each radio standard, reducing the operational burden on users while maintaining support for multiple radio types.

Inventive Principle:
Principle #25Self-service
