Sliding Fan Support Layout for Engine Compartment Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan structures in work vehicles often face challenges in maintenance accessibility, particularly around the engine compartment, due to the placement of the motor and fan configuration.
Innovation Solution
The fan structure includes a fan, a fan support, a base, and a motor, where the motor is located closer to the engine compartment than the fan, and the base is connected to the exterior frame, allowing for sliding movement to facilitate maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the motor is placed below the rotational shaft of the fan (conventional configuration), then the fan structure is compact, but maintenance accessibility around the engine compartment is poor
Solution Approach 1:
The fan support is made slidable relative to the base along a sliding direction, allowing the motor to be dynamically repositioned. During maintenance, the fan support can be slid to move the motor away from the engine compartment, providing accessibility. During operation, the fan support is positioned to maintain compact configuration and operational efficiency.
Solution Approach 2:
The motor is repositioned from a vertical arrangement (below the rotational shaft) to a horizontal arrangement (axially along the rotational axis). This dimensional change allows the motor to be located closer to the engine compartment while still enabling maintenance accessibility through the sliding mechanism of the fan support.
2Ease of repair
If the motor is located closer to the engine compartment than the fan, then maintenance accessibility is improved, but the fan structure may become more complex
Solution Approach 1:
The fan structure is segmented into distinct components: the base, the fan support that can slide relative to the base, and the motor mounted on the fan support. This segmentation allows independent positioning of each component, enabling the motor to be located closer to the engine compartment while maintaining structural integrity and operational functionality.
3Ease of operation
If the base is connected to the exterior frame with sliding capability, then maintenance accessibility is enhanced, but the structural stability may be compromised
Solution Approach 1:
The connection between the base and the exterior frame incorporates sliding capability, allowing the fan support (with the motor) to be dynamically repositioned for maintenance accessibility. The sliding mechanism is designed to maintain structural stability during operation while enabling movement when needed for maintenance purposes.

AI summary
A fan structure is provided with a fan, a fan support, a base, and a motor. The fan is provided with a rotational shaft rotatable about a rotational shaft, and a blade coupled to the rotational shaft to rotate about the rotational axis together with the rotational shaft. The fan support rotatably supports the rotational shaft. The base slidably supports the fan support so as to be slidable in the sliding direction. The motor includes a motor main body supported by a fan support opposite to the rotational shaft of the fan in the axial direction along the rotational axis, and a motor rotational shaft connected to the rotational shaft so as to rotate the rotational shaft.
