Solution Overview

Problem

Transferring fuel from a heavy fuel supply tank to a fuel tank is labor-intensive and cumbersome, especially when lifting the fuel supply tank is required.

Innovation Solution

A fuel supply guide is provided with a support member on the upper portion of the fuel tank and a body member that projects upward and away from the fuel supply port, allowing the fuel supply tank to be received and supported, thereby easing the transfer of fuel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the fuel supply tank is used to supply fuel to the fuel tank, then the fuel can be transferred, but the work of transferring the fuel while lifting the heavy fuel supply tank becomes labor-intensive and cumbersome

Engineering Contradiction:
Improveease of fuel transferVSAvoidweight of fuel supply tank
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The patent introduces a fuel supply guide as an intermediary device between the fuel supply tank and the fuel tank. The guide includes a support member that provides a resting surface for the fuel supply tank, and a body member that guides the tank during the fuel transfer process. This intermediary structure eliminates the need for operators to manually lift and hold the heavy fuel supply tank, thereby resolving the contradiction between ease of operation and the weight of the moving object.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the fuel supply tank is positioned above the fuel tank for fuel transfer, then fuel can be supplied, but the operator must manually support the heavy tank which increases workload

Engineering Contradiction:
Improvefuel transfer efficiencyVSAvoidoperator workload
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The fuel supply guide enables the fuel supply tank to serve itself during the transfer process. The support member and body member work together to automatically position and stabilize the tank at the correct height and location above the fuel tank. The structure allows the tank to be passively supported and guided without requiring active manual intervention from the operator, thus improving productivity while reducing ease of operation concerns related to workload.

Inventive Principle:
Principle #25Self-service

AI summary

To ease work of transferring a fuel from a fuel supply tank to a fuel tank, a fuel supply guide to be used to supply the fuel by using the fuel supply tank to the fuel tank having a tank body for storing the fuel and a fuel supply port on the upper side of the tank body includes a support member provided on an upper portion of the fuel tank, and a body member projecting from the support member in a direction away from the fuel supply port as the body member extends upward and projecting higher than the fuel supply port. The body member is capable of receiving the fuel supply tank by an upper portion thereof to support the fuel supply tank.
