Turning Vehicle Cabin Rear-Wall Layout for Compact Hood Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The arrangement of a condenser, compressor, and receiver dryer under the hood in turning working vehicles increases the hood size, reducing the turning radius and creating an obstruction.
Innovation Solution
Housing the condenser and receiver dryer in a lower portion of the rear wall cabin, above the hood, allowing for a smaller engine room and hood, with maintenance access facilitated through a pivotally supported open/close cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the condenser, compressor and receiver dryer are arranged under the hood, then the air conditioning equipment is housed, but the hood size increases and the turning radius becomes larger
Solution Approach 1:
The patent relocates the condenser and receiver dryer from the horizontal space under the hood to the vertical space in the lower portion of the rear wall of the cabin. This dimensional transition from horizontal to vertical arrangement allows the air conditioning equipment to be housed without increasing the hood size, thereby maintaining a compact turning radius while still providing adequate space for all necessary components
2Quantity of substance
If the condenser and receiver dryer are arranged under the hood, then the air conditioning system is complete, but maintenance access becomes difficult
Solution Approach 1:
The patent extracts the condenser and receiver dryer from the confined space under the hood and places them in the lower portion of the rear wall of the cabin, which is more accessible. This extraction allows maintenance personnel to easily access these components for inspection, repair and replacement without needing to work in the cramped engine compartment, significantly improving ease of maintenance
