Solution Overview

Problem

Skid loaders' hydraulic hose lines are prone to damage and entanglement due to exposure during operation in rough environments, leading to increased repair costs and downtime.

Innovation Solution

A universal rigid hose guard with an elongate enclosure and attachment means secures hydraulic hose lines, protecting them from entanglement and external damage by routing them through a tubular structure that can be easily installed on skid loaders, using hooks and pipe stubs for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hose lines are left loose and hanging, then they maintain flexibility and ease of connection, but they become entangled and snared by attachments during operation

Engineering Contradiction:
Improveease of connectionVSAvoidentanglement and snaring
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The protective enclosure is divided into sections with the tubular body providing a dedicated pathway for each hose line. This segmentation prevents hoses from tangling with each other or with attachment components while maintaining individual hose flexibility and connection ease.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rigid enclosure serves as an intermediary structure that guides and separates hose lines, preventing them from becoming entangled with moving attachments while still allowing for easy connection and disconnection at the endpoints.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a protective structure is added around hose lines, then protection from foreign objects is improved, but device complexity and installation difficulty increase

Engineering Contradiction:
Improveprotection from foreign objectsVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective enclosure is designed as a universal component that can be adapted to various skid loader configurations and hose line arrangements. The standardized tubular design with attachment features provides multi-functional protection while maintaining relatively simple construction and installation procedures.

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

Solution Approach 2:

The enclosure design allows hose lines to be nested within the protected longitudinal passage of the tubular body. This nested configuration provides comprehensive protection while using space efficiently and minimizing the overall complexity of the protective system.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of manufacture

If hose lines are exposed during operation in rough environments, then installation is simple and maintenance is easy, but damage from brush and debris increases repair costs and downtime

Engineering Contradiction:
Improveinstallation simplicityVSAvoiddamage resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The protective enclosure is installed beforehand to establish a protected pathway for the hose lines before operation begins. This preliminary protective measure prevents damage from brush and debris during rough environment operation, reducing repair costs and downtime while maintaining relatively simple installation.

Inventive Principle:
Principle #10Preliminary action

AI summary

A hose guard for a skid loader attachment includes an axial elongate rigid enclosure defining a central cavity, the elongate rigid enclosure having an opening at a first end and an opening at a second end. A first attachment means at the first end of the elongate rigid enclosure is configured to secure the first end of the elongate rigid enclosure to the skid loader. A second attachment means at the second end of the elongate rigid enclosure is configured to secure the second end of the elongate rigid enclosure to the skid loader whereby the elongate rigid enclosure is readily attachable and removable from the skid loader facilitating removing and exchanging different skid loader attachments, and the elongate rigid enclosure has limited freedom of motion during operation of the skid loader and attachment.
