Air conditioning attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile air conditioning units face issues with large discharge hoses that require wide window openings, leading to heat leakage and potential overheating, and are prone to dislodgment due to gravity and forces.
Innovation Solution
An air conditioning attachment with an angled outlet that fits between the window and frame, reducing the necessary window opening while preventing overheating and dislodgment, featuring a fixation element to secure the attachment in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a large discharge hose is used, then the compressor is prevented from overheating, but the window opening must be made wider leading to increased heat leakage
Solution Approach 1:
The outlet is designed as an angled portion that extends in a direction different from the main housing axis, allowing the discharge hose to be positioned vertically between the window and frame rather than horizontally. This dimensional change enables sufficient discharge opening area to prevent compressor overheating while minimizing the horizontal window opening width, thereby reducing heat leakage through the window opening.
2Loss of energy
If the discharge hose is made smaller to reduce window opening, then heat leakage is reduced, but the compressor may overheat
Solution Approach 1:
By orienting the outlet at an angle relative to the housing, the invention creates a vertical dimension for the discharge opening that does not increase the horizontal footprint. This allows the discharge opening area to be sufficiently large for proper heat dissipation while keeping the window opening width minimal, thus preventing compressor overheating without increasing heat leakage.
3Device complexity
If a standard horizontal outlet is used, then the housing structure is simple, but the attachment is easily dislodged by gravity and forces
Solution Approach 1:
The outlet is designed as an angled portion that is asymmetric relative to the housing axis, extending in a direction that allows it to be wedged between the window and frame. This asymmetric configuration creates a mechanical interlock effect where the angled outlet resists dislodgment forces better than a symmetric horizontal outlet, improving attachment reliability without significantly complicating the housing structure.
4Reliability
If the outlet extends perpendicular to the housing, then the attachment can be secured between window and frame, but the housing structure becomes more complex
Solution Approach 1:
The angled outlet creates an asymmetric geometry that naturally wedges between the window and frame, providing secure fixation. The angular configuration allows the outlet to act as a mechanical stop that resists dislodgment forces while maintaining a relatively simple housing structure, as the angle itself provides the fixation mechanism without requiring additional complex components.
