Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing signaling flares are used, then visual signaling is achieved, but auditory effect capability is lacking

Engineering Contradiction:
Improvesignaling capabilityVSAvoidpyrotechnic composition types
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent combines multiple pyrotechnic compositions (flare composition for visual effect, flash charge for auditory effect, and smoke composition for obscuration) into a single integrated flare cup assembly. This merging allows the device to simultaneously provide visual signaling, auditory effect, and smoke generation capabilities that were previously lacking in existing flares.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The flare apparatus is designed as a multi-functional device that can perform multiple signaling functions (visual, auditory, smoke) from a single unit. The flare cup contains separate but integrated compositions that enable the device to adapt to various signaling requirements, making it a universal signaling solution for different military applications.

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

2Adaptability or versatility

If visual and auditory effects are added to enhance signaling, then communication capability is improved, but device complexity increases

Engineering Contradiction:
Improvedirectional signaling capabilityVSAvoidflare cup composition structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The flare cup is segmented into distinct functional zones containing different pyrotechnic compositions. The flare composition, flash charge, and smoke composition are separated into different sections within the cup, each with its own ignition sequence. This segmentation allows complex multi-effect functionality while maintaining manageable structural organization and simplifying the ignition control mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pyrotechnic compositions are pre-arranged in a specific sequence within the flare cup, with ignition paths predetermined. The flash charge is positioned to be ignited after the flare composition, and the smoke composition is pre-positioned to ignite subsequently. This preliminary arrangement of actions eliminates the need for complex real-time control mechanisms during firing.

Inventive Principle:
Principle #10Preliminary action

3Length of moving object

If propellant charge is used to propel flare cup downrange, then flight distance is extended, but ignition timing precision becomes more difficult

Engineering Contradiction:
Improveflare cup trajectoryVSAvoidignition timing
Core Design Contradiction:
Length of moving objectVSManufacturing precision

Solution Approach 1:

The primer serves as an intermediary device that bridges the propellant charge ignition and the pyrotechnic composition ignition. When the primer is activated, it simultaneously ignites the propellant charge to propel the flare cup and ignites the flare composition through a controlled transfer path. This intermediary mechanism ensures synchronized ignition timing between propulsion and visual effect generation, eliminating timing precision issues.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A flare apparatus constructed of a flare case with a primer functionally coupled to a propellant charge. Loaded within the flare case is a flare cup, having within, a starter composition, a flare composition, and a flash charge. The flare composition is functionally coupled to the flare starter composition, and the flash charge is functionally coupled to the flare composition. Upon primer activation the propellant charge is ignited. Flame and hot gasses from the propellant charge propel the flare cup out of the flare case and downrange while also igniting the flare starter composition within the flare cup. The flare starter composition ignites the flare composition, which produces a visual artifact and subsequently ignites the flash charge which produces a visual and audible artifact at or near the end of its flight.
