Solution Overview

Problem

Existing apparatus for distressing materials, such as wood, fail to effectively reduce chatter and produce the desired features of a distressed surface due to inability to maintain the position of the cutting head.

Innovation Solution

An apparatus comprising a cutter head with a guide member and a flattening device positioned proximate to the cutter head, which compresses and flattens the material to maintain the cutting head's position, preventing chatter and gouging by ensuring consistent contact and alignment with the material surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If known apparatus (sanding heads, molded heads, embossing drums) are used to distress material surfaces, then distressing operations can be performed, but chatter and gouging cannot be effectively reduced

Engineering Contradiction:

Improveconsistency of distressed surfaceVSAvoidchatter and gouging

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A guide member is introduced as an intermediary element between the material surface and the cutter head. The guide member engages the material surface and maintains consistent positioning of the cutter head, preventing chatter and gouging while enabling the distressing operation to proceed effectively.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The guide member changes the positional parameters of the cutter head relative to the material surface, maintaining optimal engagement depth and angle. This parameter control ensures consistent distressing while eliminating the harmful chatter and gouging effects that occur with uncontrolled cutter head positioning.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If the cutter head position is not maintained, then distressing operation can proceed, but chatter occurs reducing surface quality

Engineering Contradiction:

Improvedistressing operation speedVSAvoidsurface irregularity consistency

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The guide member serves as a mediator that simultaneously enables continuous operation and maintains precise cutter head positioning. It allows the distressing operation to proceed without interruption while ensuring consistent surface irregularity formation by preventing cutter head displacement that causes chatter.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If the cutter head moves relative to the material surface, then distressing can occur, but gouging and chatter are produced

Engineering Contradiction:

Improvedepth and width consistency of surface irregularitiesVSAvoidgouging

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The guide member controls the engagement parameters between the cutter head and material surface, maintaining optimal depth and angle. This parameter control allows the cutter head to move relative to the material for distressing while preventing excessive movement that would cause gouging, and ensures consistent formation of surface irregularities.

Inventive Principle:

Principle #35Parameter changes

AI summary

An apparatus and method for distressing material, such as a board. The apparatus may include a cutter head supporting a blade, a guide member, and a flattening device. The flattening device and the guide member are positioned proximate the cutter head and on opposite sides thereof. In response to the cutter head and the surface of the material being brought into cutting contact and moved relative to each other, a resulting portion of the surface of the material is distressed. The flattening device maintains the proper vertical position of the cutter head and blade relative to the material and a material support as the material is being brought into cutting contact with the cutter head. The guide member levels warped material boards thereby bringing the board into proper elevation and engagement with the blade for cutting or scraping a top surface of the board. The material may be wood.
