Solution Overview

Problem

Current life tests for throwing mechanisms in air vehicles require manual re-attachment of weights, leading to work-related accidents, test errors, and time losses due to the need for human intervention.

Innovation Solution

An automated test system comprising a chassis, throwing mechanism, control unit, and pushing member that allows for the automatic throwing and re-attachment of weights, eliminating the need for human intervention through a mechanism involving a control unit, adjuster, and motor-driven transfer member to manage the pushing member's movement and contact with the weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual re-attachment of weights is used in life tests, then the throwing mechanism can be tested, but work-related accidents, test errors, and time losses occur due to human intervention

Engineering Contradiction:

Improvetesting reliabilityVSAvoidwork-related accidents and test errors

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The test system enables automatic re-attachment of weights to the throwing mechanism through a robotic arm or transfer mechanism, eliminating the need for manual human intervention. The system performs its own testing operations autonomously, thereby preventing work-related accidents and human errors while maintaining testing reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical operation of attaching weights with an automated mechanical system. A robotic arm or automated transfer mechanism controlled by a control unit substitutes human hands and operations, eliminating harmful factors associated with manual labor while preserving the mechanical testing function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual re-attachment process is used, then the throwing mechanism can be tested, but time losses occur due to the repetitive manual operation

Engineering Contradiction:

Improvetesting capabilityVSAvoidtime losses in re-attachment process

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The automated test system performs weight re-attachment operations autonomously without human intervention. The system can continuously cycle through testing operations at a controlled speed, eliminating the time losses associated with manual setup and operation while maintaining accurate and reliable testing capabilities.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The automated system enables continuous testing operations by automatically re-attaching weights without the interruptions inherent in manual processes. The control unit manages a continuous cycle of weight attachment, throwing mechanism operation, and reset, maximizing productivity and eliminating idle time between test cycles.

Inventive Principle:

Principle #20Continuity of useful action

3Object-affected harmful factors

If automated test system is implemented, then human intervention is eliminated and safety is improved, but device complexity increases due to additional components

Engineering Contradiction:

Improvework-related accidentsVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The automated test system uses a self-contained robotic or automated mechanism for weight re-attachment, eliminating the need for human operators and associated safety hazards. While the system complexity increases due to automated components, this is justified by the complete elimination of work-related accidents and human exposure to testing hazards.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The automated test system is designed with multi-functional components that perform multiple operations. The control unit manages various functions including weight attachment, throwing mechanism activation, and system monitoring, thereby consolidating what could be multiple separate systems into a unified platform that improves safety without proportionally increasing overall complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
