Brush Stuffing Machine Linear Guide Mechanism

Solution Overview

Problem

Brush tamping machines face challenges in achieving faster cycle times due to inefficiencies in the movement of the tamping tool and guide, leading to increased friction and complexity.

Innovation Solution

The tamping tool with a pivotable tip features a linear guide and a tongue that performs a linear thrust movement, allowing for high-speed, low-effort, and precise reversible pivoting, reducing friction and eliminating the need for a separate bundle displacer, with a cam-driven mechanism for synchronization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the tongue follows a circular arc path in the guide during pivoting movement, then the tamping tool can be pivoted between bundle receiving position and stuffing position, but friction increases and cycle time increases

Engineering Contradiction:

Improvecycle timeVSAvoidguide shape complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent applies the inverse of this principle by using a linear guide instead of a curved guide. The guide in the tip extends linearly, and the front end of the tongue performs a linear pushing movement relative to the tucking tool, eliminating the circular arc path that caused increased friction and cycle time.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Ease of operation

If the guide in the tip is shaped as a circular arc section, then the tongue can follow the pivoting movement, but friction against the guide increases

Engineering Contradiction:

Improvetongue guidanceVSAvoidfriction

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The patent applies the inverse of this principle by using a linear guide instead of a curved guide. The guide in the tip extends linearly, reducing friction against the guide during the linear pushing movement of the tongue's front end.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Stability of the object's composition

If the tongue performs a circular arc movement until plugged in, then it follows the pivoting tool movement, but adverse lateral movement component occurs causing strain on the tip end and additional friction

Engineering Contradiction:

Improvebundle insertion stabilityVSAvoidlateral movement strain

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent applies the inverse of this principle by using a linear guide instead of a curved guide. The guide in the tip extends linearly, and the front end of the tongue performs a linear pushing movement relative to the tucking tool, eliminating the circular arc path that caused adverse lateral movement components, strain on the tip end, and additional friction.

Inventive Principle:

Principle #14Spheroidality (Curvature)
