Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional simulated munitions are used for training, then training can be conducted, but realistic firing conditions and operational accuracy cannot be simulated

Engineering Contradiction:
Improvetraining effectivenessVSAvoidsimulation capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The training round incorporates a telescopic assembly that allows dynamic adjustment of the round's length between extended and retracted states. This dynamic structure enables the round to simulate different firing conditions and trajectory profiles, enhancing training realism and adaptability without compromising structural integrity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The training round integrates multiple functions including telescopic movement capability, electronic sensor integration for data collection, and adjustable configuration for different training scenarios. This multi-functionality allows a single training round design to serve multiple training purposes, from basic handling to advanced tactical decision-making exercises

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

2Ease of manufacture

If the training round structure is simplified, then manufacturing is easier, but the ability to provide real-time feedback and comprehensive oversight is reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidfeedback capability
Core Design Contradiction:
Ease of manufactureVSLoss of information

Solution Approach 1:

The telescopic assembly employs a nested structure where one tube is inserted within another, allowing compact storage and simplified manufacturing while maintaining the capability for length adjustment. The electronic components are similarly integrated within the existing round structure, minimizing additional manufacturing complexity while maximizing feedback functionality

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The training round incorporates self-contained electronic sensors and communication systems that automatically collect, process, and transmit firing data without requiring external intervention. This self-service capability ensures continuous real-time feedback while keeping the overall system design relatively simple and manufacturable

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enhances training effectiveness and operational accuracy by providing real-time feedback and comprehensive oversight, enabling troops to make tactical decisions during simulated indirect fire missions.

Implementation Method 1

A hydraulic system is situated between projectile shell and the stabilizing rod to adjust a length of the training round. The hydraulic system has a first tube fixedly connected to the projectile shell, a second tube fixedly connected to stabilizing rod and movably connected to the projectile shell, and a conduit for a transmission of a fluid between the first tube and the second tube.

Methodology Applied
Scientific EffectHydraulic system: Hydraulic Press

Implementation Method 2

A weight of the top end induces the telescopic movement between the top end and the bottom end of the training round.

Methodology Applied
Scientific EffectGravity: Gravitation

AI summary

A training round for performing indirect fire mission, including a top end oriented towards a direction of projectile motion of the training round. A bottom end is situated opposite to the top end. The top end and the bottom end are separated by a first distance. An adjuster is arranged between the top end and the bottom end to adjust a length of the training round. The adjuster compresses such that the top end and the bottom end are separated by a second distance. The second distance is less than the first distance. A round sensor attached to the training round and communicatively couples to a simulation computer while performing the indirect fire training mission.
