Engine Generator Multi-Handle Transport Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine generators are limited in transport methods and are not compatible with various transport techniques, making them difficult to move and position effectively.
Innovation Solution
The engine generator design includes a bottom cover with wheels, a first and second stationary handle, and a draw handle, allowing for multiple transport methods such as lifting, pushing, and pulling, with the handles positioned to enable easy handling by one or two people and reduce the risk of tilting or rolling during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only a single transport handle is provided, then the device complexity is reduced, but the adaptability for various transport methods deteriorates
Solution Approach 1:
The patent provides multiple handles (first transport handle, second transport handle, and draw handle) that can be used for different transport methods including lifting, pushing, and pulling. This multi-functional design allows the engine generator to be transported using various methods depending on the situation, thereby improving adaptability without requiring completely different transport systems for each method.
Solution Approach 2:
The transport system is segmented into multiple independent handles, each suited for specific transport operations. The first and second transport handles are positioned at different locations on the case, while the draw handle is separately provided for pulling operations. This segmentation allows each handle to be optimized for its specific function while collectively providing comprehensive transport capability.
2Ease of operation
If handles are positioned close together, then the device complexity is reduced, but the ease of operation for multiple people deteriorates
Solution Approach 1:
The handles are arranged in three-dimensional space rather than just linearly along the case. The first transport handle is provided on one side of the case, the second transport handle on the opposite side, and the draw handle is positioned externally. This spatial distribution in multiple dimensions allows multiple people to grasp handles without their bodies interfering with each other, greatly improving ease of operation for collaborative transport.
3Ease of operation
If the engine generator is designed without wheels, then the manufacturing complexity is reduced, but the ease of operation for transport deteriorates
Solution Approach 1:
The patent merges the wheel assembly with the case structure, where the case serves dual purposes: it accommodates the engine and generator internally, and simultaneously provides external handles for transport. The wheels are integrated into this combined structure, allowing the engine generator to be both manufactured as a unified unit and transported easily when needed, thus balancing manufacturing simplicity with transport ease.

AI summary
An engine generator accommodating an engine and a generator inside a case. A first stationary handle that extends in the width direction is mounted in the rear section of the case. A second stationary handle is mounted on the upper front part of the case. A draw handle is provided so as to swing in the vertical direction in relation to the second stationary handle. The second stationary handle is manually grasped and the engine generator is moved. The first and second stationary handles are grasped and the engine generator is lifted. The draw handle is pulled to move the engine generator.
