Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current work machines, such as loaders, are often too large to maneuver through narrow entryways, limiting their accessibility in residential and commercial settings due to their large size and footprint.
Innovation Solution
A compact loader design featuring a tracked drive assembly with endless tracks, torsion axles, and a hingedly connected operator cab, allowing for reduced dimensions and improved maneuverability while maintaining functionality through a compact footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If loaders are manufactured in large sizes to maintain structural strength and functionality, then operational capability is improved, but maneuverability and accessibility to confined spaces deteriorates
Solution Approach 1:
The loader is divided into modular components including the frame, tracked drive assembly, loader arms, and operator cab that can be independently configured. This segmentation allows the machine to maintain structural integrity where needed while reducing overall footprint for maneuverability in confined spaces.
Solution Approach 2:
The patent transitions from conventional wheel-based movement to tracked drive assembly, changing the dimension of contact with the ground. The endless tracks distribute weight over a larger surface area, improving ground contact and stability while reducing the machine's overall footprint for better maneuverability in confined spaces.
2Adaptability or versatility
If loaders are manufactured in large sizes to carry and operate various attachments, then functionality and versatility are improved, but footprint and accessibility to narrow entryways deteriorates
Solution Approach 1:
The loader frame is designed with a universal attachment interface that can accommodate multiple types of attachments including loader arms, buckets, and other implements. This multi-functionality allows a single compact machine to perform diverse tasks without requiring multiple specialized large machines.
Solution Approach 2:
The tracked drive assembly is integrated within the frame structure in a nested configuration, where the tracks are positioned to optimize space utilization. This nesting approach minimizes the overall footprint while maintaining the structural capacity to support various attachments.
3Device complexity
If traditional wheel-based drive systems are used, then structural simplicity is maintained, but maneuverability in confined spaces and ground contact capability deteriorates
Solution Approach 1:
The tracked drive assembly incorporates hydraulic mechanisms to power the drive sprockets and control track movement. This hydraulic system provides precise control and sufficient power for maneuvering the compact loader in confined spaces while maintaining a relatively simple overall drive system architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compact loader achieves enhanced maneuverability and accessibility in confined spaces while maintaining operational efficiency and functionality, enabling efficient operation in tight areas.
Implementation Method 1
The torsion axle shiftably supports a single one of the one or more roller wheels relative to the idler wheels and urges the single roller wheel into rolling engagement with the lower run, with the torsion axle permitting up-and-down movement of at least part of the lower run relative to the idler wheels
