Gas Lifting Assembly with Pivoting Basket for Refueling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices are inadequate for safely and efficiently lifting and tilting gas cans, particularly for individuals who lack the necessary strength, making it difficult to refuel machines like lawn mowers.
Innovation Solution
A cart-based lifting device with a pivotally coupled basket that can be selectively lifted and tilted, allowing for horizontal or angled positioning of a gas can, enabling easy lifting and pouring of gasoline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional lifting device is used to lift a gas can, then the lifting function is achieved, but the device cannot tilt the gas can for pouring
Solution Approach 1:
The patent combines the lifting function and tilting function into a single integrated device. The basket is pivotally coupled to the lift mechanism, allowing the same structure to perform both vertical lifting and angular tilting operations on the gas can, thereby achieving versatility without proportionally increasing device complexity.
Solution Approach 2:
The lifting device is designed with multi-functionality to handle both lifting and tilting operations. The basket-lift combination allows the device to adapt to different operational requirements (lifting alone or lifting plus tilting), making it a universal solution for gas can handling tasks.
2Ease of operation
If a person manually lifts and tilts a gas can, then the operation is simple, but it requires significant physical strength
Solution Approach 1:
The patent introduces a basket as an intermediary between the user and the gas can. The basket receives the gas can and transfers it to the lift mechanism, which then performs the heavy lifting and tilting actions. This intermediary structure allows users with limited strength to operate the system safely and easily.
Solution Approach 2:
The patent replaces the manual mechanical system (human arm and back strength) with a mechanical lifting system. The lift mechanism uses mechanical advantage through pulleys, cables, and winches to substitute human physical effort, enabling elderly or disabled individuals to operate the device.
3Ease of operation
If the basket is fixed in horizontal position, then lifting is stable, but pouring is inconvenient
Solution Approach 1:
The patent makes the basket dynamic rather than fixed. The basket can pivot between a horizontal position (stable for lifting and transport) and a tilted position (convenient for pouring). This dynamic positioning capability allows the system to adapt to different operational phases, optimizing both stability and pouring convenience as needed.

AI summary
A gas can lifting assembly for lifting and tilting a gas can includes a cart that may be rolled along the support surface. A lift is coupled to the cart and the lift is selectively manipulated. A basket is pivotally coupled to the lift such that the lift selectively lifts and lowers the basket. A gas can is selectively positioned in the basket. In this way the gas can may be selectively lifted and lowered for refueling a machine. The basket is selectively positioned in a first position having the basket being horizontally oriented. Additionally, the basket is selectively positioned in a second position having the basket being tilted to pour gasoline from the gas can.
