Feed Roll Mount With Recessed Region For Replaceable Flute Inserts

Solution Overview

Problem

Existing feed roll assemblies for log handling and debarking face challenges in maintaining effective contact and traction with logs due to wear and tear, leading to reduced efficiency and increased maintenance costs.

Innovation Solution

The proposed feed roll assembly incorporates an elongate mount with a recessed region that couples an insert, such as a flute element, to the feed roll. This configuration ensures secure engagement and transmission of forces, while the insert's design provides enhanced traction through serrated teeth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional feed roll assemblies are used, then initial manufacturing cost is lower, but wear and tear increases maintenance costs and reduces reliability

Engineering Contradiction:

Improveoperational reliabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The feed roll assembly is divided into separate modular components: a feed roll body, removable flute inserts, and an elongate mount with recessed region. This segmentation allows the flute inserts to be easily replaced when worn, improving operational reliability without requiring complete replacement of the entire feed roll assembly, thus managing manufacturing complexity through standardized modular parts.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The flute inserts are designed to be received within the recessed region of the elongate mount, creating a nested configuration. This nesting arrangement secures the flute inserts to the feed roll body while allowing for easy removal and replacement, balancing reliability improvement with manufacturing ease through a compact integrated design.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of repair

If flute inserts are made replaceable, then maintenance cost is reduced, but device complexity increases

Engineering Contradiction:

Improvemaintenance easeVSAvoidassembly complexity

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The feed roll assembly is divided into separate modular components: a feed roll body, removable flute inserts, and an elongate mount with recessed region. This segmentation allows the flute inserts to be easily replaced when worn, improving operational reliability without requiring complete replacement of the entire feed roll assembly, thus managing manufacturing complexity through standardized modular parts.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The design transitions from a static integrated flute structure to a dynamic replaceable insert system. The elongate mount with recessed region provides a secure but removable connection, allowing the flute inserts to be dynamically replaced when worn, thereby improving maintenance ease while controlling assembly complexity through standardized interfaces.

Inventive Principle:

Principle #15Dynamics

3Force

If insert is securely coupled to feed roll, then force transmission is improved, but engagement precision requirements increase

Engineering Contradiction:

Improveforce transmissionVSAvoidengagement precision

Core Design Contradiction:

ForceVSManufacturing precision

Solution Approach 1:

The flute inserts are designed to be received within the recessed region of the elongate mount, creating a nested configuration. This nesting arrangement secures the flute inserts to the feed roll body while allowing for easy removal and replacement, balancing reliability improvement with manufacturing ease through a compact integrated design.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The elongate mount with recessed region acts as an intermediary component between the feed roll body and the flute inserts. This intermediary structure provides a standardized interface that ensures secure force transmission while accommodating manufacturing tolerances, thereby reducing the precision requirements for direct engagement between the feed roll and inserts.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An elongate mount couples an insert to a feed roll via a proximal edge thereof. The proximal edge of the elongate mount faces both outwards in part and forwards in part. The elongate mount has a recessed region that is twisted in part. The insert is shaped to be received at least in part within and matingly engage with the elongate mount via the recessed region. The elongate mount is shaped to enclose the proximal edge, spaced-apart ends and backing fact of the insert.
