Solution Overview

Problem

Conventional dual wheel assemblies for agricultural vehicles face challenges with wider tires, including increased stress, metal fatigue, and high manufacturing costs, as well as difficulties in easily removing or adding outer wheels without assistance.

Innovation Solution

A dual wheel system featuring a first and second wheel with specific bolt patterns, a transition plate, and a tube and rim extension segment, allowing for easier installation and removal of outer wheels, reducing stress on components and manufacturing costs by using a combination of tubes and shorter rim extension segments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional dual wheel assemblies are used with wider tires, then the vehicle can handle heavier loads and work in wet/muddy conditions, but the stress on wheel components increases leading to metal fatigue and higher manufacturing costs

Engineering Contradiction:

Improveload handling capacityVSAvoidmetal fatigue resistance

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The wheel assembly is segmented into multiple components: inner wheel, outer wheel, transition plate, and fastening system. This segmentation allows each component to be optimized independently for strength and fatigue resistance, with the transition plate distributing loads across multiple attachment points.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wheel assembly uses composite construction combining different materials and structural forms - the transition plate with its pattern of holes provides both structural integrity and weight optimization, while the combination of inner and outer wheels creates a composite load-bearing system that reduces stress on individual components.

Inventive Principle:

Principle #40Composite materials

2Strength

If conventional dual wheel assemblies are used with wider tires, then the vehicle can handle heavier loads, but the manufacturing costs increase

Engineering Contradiction:

Improveload handling capacityVSAvoidmanufacturing cost

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

By segmenting the wheel assembly into standardized components (inner wheel, outer wheel, transition plate), each part can be manufactured independently using optimized processes, reducing overall manufacturing complexity and cost while maintaining high load handling capacity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transition plate serves multiple functions: structural support, load distribution, and attachment interface for both inner and outer wheels. This multi-functionality reduces the need for additional specialized components, thereby lowering manufacturing costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If conventional dual wheel assemblies are used, then the vehicle structure is simple, but the outer wheel cannot be easily removed or added without assistance

Engineering Contradiction:

Improvewheel assembly structureVSAvoidouter wheel removal ease

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The fastening system is designed to be dynamically adjustable - the transition plate with its pattern of holes accommodates different fastening configurations, allowing the outer wheel to be easily attached or removed by loosening fasteners without requiring complex tools or assistance, while maintaining structural integrity during operation.

Inventive Principle:

Principle #15Dynamics

4Ease of operation

If the wheel assembly is designed for easier outer wheel removal, then operator can remove/replace wheels independently, but the structural integrity and stability may be compromised

Engineering Contradiction:

Improveouter wheel removal easeVSAvoidwheel assembly stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The transition plate is pre-configured with a pattern of holes that align with both inner and outer wheels, establishing the correct geometric relationship and stability before the outer wheel is attached. This preliminary structural arrangement ensures that when the outer wheel is removed and reattached, the assembly maintains its stability and center of gravity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The transition plate structure provides inherent structural support and stability before the outer wheel is attached, cushioning against potential instability during the removal and reattachment process. The pattern of holes and plate geometry are designed to maintain assembly integrity even when the outer wheel is detached.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A dual wheel system includes a first wheel, a second wheel, and a transition plate arranged between the first and second wheels. Each wheel includes a rim with a disk positioned transverse to a longitudinal axis. The disk of the first wheel has a first plurality of holes arranged concentric about the longitudinal axis with a first bolt pattern, and the disk of the second wheel has a second plurality of holes arranged concentric about the longitudinal axis with a second bolt pattern. The transition plate includes an outer ring of holes for fastening the wheels to the transition plate via the first and second plurality of holes, and an inner ring of holes for fastening the transition plate to an axle flange of a work vehicle.
