Work Vehicle AC Panel Layout for Cooling and Heating Variants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production cost of work vehicles equipped with a cabin and an air conditioner is high due to the need for two types of panels: one that supports both cooling and heating, and another that supports only cooling.
Innovation Solution
A panel design for work vehicles that includes at least one first opening for cooling air and a second opening for heating air, with the second opening optionally equipped with a duct for heating air distribution or a cover for cooling-only configurations, allowing for standardization and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two types of panels are prepared (one for cooling and heating, another for cooling only), then the air conditioning functionality is satisfied, but the production cost increases
Solution Approach 1:
The panel is designed with both a first opening and a second opening, allowing the same panel to serve dual purposes: the first opening handles cooling air flow while the second opening handles heating air flow. This multi-functional design eliminates the need for separate panels for different air conditioning configurations, thereby reducing production costs while maintaining versatility.
Solution Approach 2:
The panel incorporates a switchable configuration at the second opening where a duct can be installed or removed. When the duct is installed, the panel supports both cooling and heating; when removed, it supports cooling only. This dynamic adaptability allows manufacturers to produce a standardized panel that can be configured for different market needs without creating entirely different panel types.
2Adaptability or versatility
If a panel supports both cooling and heating functions, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The panel is segmented into multiple functional openings: the first opening for cooling air flow and the second opening for heating air flow. Each opening can be independently configured, allowing the panel to handle both cooling and heating functions through distinct, manageable pathways rather than a complex integrated system.
Solution Approach 2:
The duct at the second opening is designed to be switchable or removable, allowing the panel structure to adapt its complexity based on the required functionality. When heating is not needed, the duct can be removed, simplifying the panel structure while maintaining the capability to support heating when required.
3Adaptability or versatility
If the second opening is always open for heating air flow, then the heating functionality is improved, but the cooling-only configurations become problematic
Solution Approach 1:
The second opening is designed with a switchable duct that can be installed or removed based on the vehicle's air conditioning requirements. For heating-capable vehicles, the duct is installed to enable heating air flow. For cooling-only vehicles, the duct is removed and replaced with a cover, allowing the use of a standardized panel design across different configurations while maintaining proper functionality for each.
Solution Approach 2:
The duct at the second opening is extracted as a separate, optional component rather than being permanently integrated into the panel. This allows the duct to be removed in cooling-only configurations and replaced with a simple cover, eliminating the problem of unnecessary heating openings while maintaining the standardized panel design.

AI summary
A work vehicle includes a body provided with a panel configured to be equipped with an air conditioner, the panel having at least one first opening and a second opening through each of which air supplied from the air conditioner flows out toward one or more occupants, and the second opening being provided with one of a duct extending from the second opening to the air conditioner and a cover blocking the second opening.
