Work Vehicle Rear Camera Nesting in Air Conditioner Casing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear monitoring cameras on work vehicles, when positioned on the bottom or rear of air conditioning units, either block the operator's view or are prone to damage from external obstacles due to protrusion.
Innovation Solution
The rear monitoring camera is housed within a recess in the air conditioner casing, specifically within the blower part cover, which includes a wind shielding cover that positions the camera between cooling fans, using anti-vibration rubber for mounting, to prevent obstruction of the view and minimize damage from external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rear monitoring camera is disposed on the bottom face of the rear part of the air conditioner, then the camera is protected from external obstacles, but the camera blocks the operator's rear field of view
Solution Approach 1:
The rear monitoring camera is nested within a recess formed in the air conditioner casing, allowing the camera to be housed inside the casing structure rather than protruding outward. This nesting approach protects the camera from external obstacles while preventing it from blocking the operator's rear field of view through the rear window.
2Ease of operation
If the rear monitoring camera is disposed on the rear face of the rear part of the air conditioner, then the camera has a clear view, but the camera is prone to damage from external obstacles
Solution Approach 1:
The camera is nested within a recess in the air conditioner casing, positioned to maintain clear rear monitoring capability while being protected from external obstacles by the casing structure.
Solution Approach 2:
The camera is positioned in a recess that extends into the casing depth, changing the spatial dimension from a surface-mounted configuration to an embedded configuration. This dimensional change allows the camera to maintain its monitoring function while gaining protection from external obstacles.
3Ease of repair
If the rear monitoring camera protrudes from the air conditioner casing, then the camera is easily accessible for maintenance, but the camera is vulnerable to damage from external obstacles
Solution Approach 1:
The camera is nested within a recess in the air conditioner casing, providing protection from external obstacles while remaining accessible for maintenance through the recess opening.
Solution Approach 2:
The recess structure acts as an intermediary between the camera and the external environment, providing protection from obstacles while maintaining accessibility for maintenance activities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration ensures the rear monitoring camera does not obstruct the operator's view and is less likely to be damaged by external obstacles, while also maintaining airflow and reducing temperature elevation.
Implementation Method 1
using anti-vibration rubber for mounting
Implementation Method 2
two cooling fans. The condenser is accommodated in the air conditioner casing while being disposed along a transverse direction of the work vehicle. The cooling fans are accommodated in the air conditioner casing while being disposed adjacent to each other in the transverse direction
Implementation Method 3
The blower part cover covers rear sides of the cooling fans. The blower part cover forms a wind flow path for blown wind from the cooling fans
