Solution Overview

Problem

Miniature munitions using Enhanced Bit Rate-1553 protocol are incompatible with military standard-1760 and MIL-STD-1553B aircraft interfaces, requiring expensive carriage modifications and hindering integration costs and compatibility.

Innovation Solution

The MIL-STD-1760 interface bridge provides interface translation from MIL-STD-1553B to miniature munitions interfaces using a dual logical interface translator controlled by a programmable microcontroller, eliminating the need for costly modifications and enabling carriage on any MIL-STD-1760 platform with a small, self-contained converter connector.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If miniature munitions use Enhanced Bit Rate-1553 protocol, then communication capability is improved, but compatibility with MIL-STD-1760 aircraft interfaces deteriorates

Engineering Contradiction:

Improvecommunication capabilityVSAvoidinterface compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces an interface bridge as an intermediary device that connects the Enhanced Bit Rate-1553 protocol used by miniature munitions to the MIL-STD-1760 protocol used by aircraft interfaces. This bridge translates between the two incompatible protocols, allowing communication capability to be improved while maintaining compatibility with existing aircraft systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If interface translation is implemented, then compatibility is improved, but device complexity increases

Engineering Contradiction:

Improveinterface compatibilityVSAvoidtranslator complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The interface bridge is designed to perform multiple functions: it acts as a MIL-STD-1760 remote terminal, an Enhanced Bit Rate-1553 bus controller, and a protocol translator simultaneously. By consolidating these functions into a single multi-functional device, the patent reduces overall system complexity while maintaining compatibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If carriage modifications are made for protocol compatibility, then compatibility is improved, but manufacturing cost increases

Engineering Contradiction:

Improveinterface compatibilityVSAvoidintegration cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent segments the compatibility solution into a separate, standalone interface bridge device rather than modifying the aircraft carriage structure. This segmentation allows the translation function to be added without costly modifications to existing aircraft systems, significantly reducing manufacturing and integration costs.

Inventive Principle:

Principle #1Segmentation

AI summary

A military standard-1760 (MIL-STD-1760) interface bridge can include a housing, a translator device, and an energy storage device. The housing can include a MIL-STD-1760 connector on a first end and a weapon side connector on a second end. The translator device can translate a MIL-STD-1553B remote terminal (RT) protocol to a weapon side signaling protocol and translate the weapon side signaling protocol to the MIL-STD-1553B RT protocol. The energy storage device can be coupled to the operating power of the MIL-STD-1760 connector and can be configured to provide power to the translator device for a duration after the power from the MIL-STD-1760 connector is disconnected.
