Solution Overview

Problem

Existing skid steer road widening and shouldering attachment devices face issues with conveyor belt misalignment due to debris pressure and motion, requiring realignment and manual disassembly for transport, which causes time delays.

Innovation Solution

A flexible skid steer road widening and shouldering attachment device with an adjustable spreader system, improved hopper design for debris deflection, reduced-sized rollers, and tandem casters for weight distribution, eliminating the need for disassembly during transport and providing precise debris placement control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the conveyor belt system is used to transport debris, then debris transport function is achieved, but the conveyor belt becomes misaligned due to pressure from debris and vehicle motion

Engineering Contradiction:
Improvedebris transport capabilityVSAvoidconveyor belt alignment
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies dynamics by making the conveyor belt tensioning system adjustable and responsive to operational conditions. The tensioning mechanism allows the conveyor belt tension to be dynamically adjusted during operation to compensate for misalignment caused by debris pressure and vehicle motion, maintaining proper alignment without requiring disassembly or complex realignment procedures

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of conveyor belt tension from fixed to variable. By incorporating an adjustable tensioning mechanism, the system can modify the tension parameter in response to operational conditions, preventing misalignment while maintaining continuous debris transport capability

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the device is designed with standard-sized rollers and hopper, then debris handling capacity is sufficient, but the device requires disassembly for transport which causes time delays

Engineering Contradiction:
Improvedebris handling capacityVSAvoiddisassembly and reassembly time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies segmentation by dividing the device into modular components with standardized interfaces. The rollers and hopper are designed as separable modules that can be quickly detached and reattached during transport operations, eliminating the need for complete disassembly while maintaining full debris handling capacity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements universality by designing the rollers and hopper with standardized mounting interfaces that serve multiple functions: they can be quickly detached for transport, easily reattached for operation, and potentially interchanged with other compatible components. This multi-functionality reduces transport preparation time while preserving debris handling capability

Inventive Principle:
Principle #6Universality (Multi-functionality)
