Mobile Power Generator Wheel Support via Side-Mounted Guide Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile power generator apparatus face challenges in accommodating a power generator with large wheels, as larger wheels require a higher axle position, making it difficult to secure space for the generator and creating maintenance access issues.
Innovation Solution
The use of at least three guide rollers on each wheel, mounted on the frame's side walls, allows for larger wheel diameters without increasing the frame height, eliminating the need for a conventional axle and providing space for the generator and maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the left and right wheels have a greater outer diameter to move more smoothly on uneven surfaces, then the mobility and comfort are improved, but the centers of the wheels would be located at a high position, requiring the axle to extend through a relatively high interior region of the frame, making it difficult to secure space for the power generator
Solution Approach 1:
The patent extracts the axle from the conventional configuration and replaces it with guide rollers mounted on the side walls of the frame. This allows the wheels to be supported at a lower position while maintaining their large outer diameter, thus securing space for the power generator below the wheel centers.
Solution Approach 2:
Instead of supporting the wheels from below through a horizontal axle, the patent mounts the guide rollers on the vertical side walls of the frame. This dimensional change in support configuration allows the wheel centers to be positioned lower, creating vertical space for the power generator while maintaining large wheel diameter for improved mobility.
2Ease of operation
If the left and right wheels have a greater outer diameter, then the smoothness of movement on uneven surfaces is improved, but the left and right side walls of the frame are covered with the wheels, making it difficult to form openings for maintenance of the power generator
Solution Approach 1:
The patent extracts the wheel support function from the central axle configuration and relocates it to guide rollers mounted on the side walls. This creates vertical clearance between the wheels and the frame side walls, allowing maintenance openings to be formed in the side walls for accessing the power generator.
3Device complexity
If the axle is provided to extend through a relatively high interior region of the frame to support large wheels, then the wheel support is achieved, but it is difficult to secure space inside the frame for accommodating the power generator
Solution Approach 1:
The patent extracts the axle component entirely and replaces it with guide rollers mounted on the side walls. This eliminates the need for a high-position horizontal axle, allowing the power generator to be positioned lower in the frame with sufficient space, while still supporting large-diameter wheels.

AI summary
Mobile power generator apparatus includes: left and right wheels attached to a frame having a power generator mounted therein; three guide rollers provided for each of the wheels for rotatably supporting the rim of the wheel at three positions of the rim; and mounting sections for respectively mounting the three guide rollers on a side wall of the frame, so that each of the wheels is rotatably supported by the three guide rollers on one of the side walls of the frame.
