Movable Fall-Prevention Structure for Low-Drag Impact Testing

Solution Overview

Problem

Conventional impact test devices require larger motors and increased power consumption due to the weight and wind resistance caused by support plates perpendicular to the traveling direction, leading to higher costs and device size.

Innovation Solution

An impact test device with a dolly and a fall preventing structure that includes a first section movable in the traveling direction, reducing weight and air resistance by using a dolly with columnar supports and a lightweight net-like second support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a support plate is installed perpendicular to the traveling direction of the impact table to prevent the test article from falling over, then the test article stability is improved, but the weight of the impact table increases and air resistance increases, leading to increased power consumption

Engineering Contradiction:

Improvetest article stabilityVSAvoidpower consumption

Core Design Contradiction:

Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The support plate is made movable relative to the impact table, allowing it to be positioned only when needed to prevent falling during the impact test. This dynamic configuration reduces air resistance during high-speed traveling while maintaining test article stability when required.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The support function is separated from the impact table structure. The support plate can be independently positioned and removed, allowing the impact table to operate with minimal weight and air resistance when the support function is not needed.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If a support plate is installed perpendicular to the traveling direction of the impact table to prevent the test article from falling over, then the test article stability is improved, but the weight of the impact table increases, requiring a larger motor and increasing device size

Engineering Contradiction:

Improvetest article stabilityVSAvoidimpact table weight

Core Design Contradiction:

Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The support plate is made movable relative to the impact table, allowing it to be positioned only when needed to prevent falling during the impact test. This dynamic configuration reduces air resistance during high-speed traveling while maintaining test article stability when required.

3Stability of the object's composition

If a support plate is installed perpendicular to the traveling direction of the impact table to prevent the test article from falling over, then the test article stability is improved, but the air resistance increases, requiring a larger motor and increasing initial cost

Engineering Contradiction:

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The support plate is made movable relative to the impact table, allowing it to be positioned only when needed to prevent falling during the impact test. This dynamic configuration reduces air resistance during high-speed traveling while maintaining test article stability when required.

Inventive Principle:
