Integrated Fuel Tank Assembly for Leak-Free Motor Grader Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internal space constraints on motor graders necessitate multiple interconnected fuel tanks, leading to hose-related leaks and inefficiencies due to exposure to harsh environments and wear and tear, while existing solutions do not adequately address these issues.
Innovation Solution
A single, integral fuel tank design that integrates with the front frame of a motor grader, featuring a body and neck configuration that allows for pivotability and includes a roll-over-protection apparatus to secure the operator compartment, eliminating the need for auxiliary tanks and hoses by storing all fuel within a unified chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple interconnected fuel tanks are used to meet operation requirements, then fuel capacity is sufficient, but hose-related leaks and wear occur due to exposure to harsh environments
Solution Approach 1:
The patent combines multiple separate fuel tanks into a single integrated fuel tank assembly with a unified chamber. This eliminates the need for multiple hoses and connections between tanks, directly resolving the reliability issue while maintaining sufficient fuel capacity through the enlarged single chamber design
2Quantity of substance
If multiple fuel tanks are mounted on the front frame, then operational fuel requirements are met, but the system complexity and number of components increase
Solution Approach 1:
The patent merges multiple fuel tanks into one integrated assembly consisting of a single chamber with integrated mounting features. This reduces the device complexity by eliminating redundant tanks, mounts, and interconnecting hoses while maintaining the total fuel storage capacity needed for operation
3Adaptability or versatility
If hoses extend over the articulation joint, then flexibility is provided for steering, but the hoses are exposed to the outside environment and develop leaks
Solution Approach 1:
By integrating the fuel tank directly into the front frame structure with pivotable mounting, the patent eliminates the need for external hoses extending over the articulation joint. The fuel tank itself becomes part of the structural assembly, removing it from environmental exposure while maintaining steering flexibility through the pivotable connection
Solution Approach 2:
The fuel tank assembly serves multiple functions: it provides fuel storage, structural support as part of the front frame, and pivotable connection for steering. This multi-functionality eliminates the need for separate hoses and mounting structures, reducing environmental exposure points

AI summary
A structurally integrated fuel tank and method of assembling is disclosed. The fuel tank may comprise a body and a neck disposed on the body. The neck may be configured to be coupled to an arm of a front frame of a machine. The body may comprise a cover, an endwall and a base. The cover includes a cover hitch that defines an upper pivot bore centered about a pivot axis. The upper pivot bore is configured to receive a pivot fastener about which the fuel tank is pivotable. The endwall may be disposed below and coupled to the cover. The base may be coupled to the endwall, and may include a lower hitch that extends outward and away from the endwall. The neck and the body together define a chamber configured to store fuel. The cover is a top of such chamber.
