Saddle window air conditioner with an adjustable bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Variations in wall or window thickness make it difficult to install saddle window air conditioners, which require adjustable length features to fit various window sizes.
Innovation Solution
A saddle window air conditioner with an adjustable bridge that includes a first sleeve slidably received within a second sleeve, facilitated by a gear assembly allowing the length between interior and exterior casings to be adjusted by rotating the gear assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bridge length is fixed, then the manufacturing and installation process is simple, but the air conditioner cannot adapt to windows and walls with varying thicknesses
Solution Approach 1:
The bridge structure is transformed from a fixed static design to a dynamic adjustable one. The telescopic mechanism with nested sleeves allows the bridge length to be varied, enabling adaptation to different window thicknesses while maintaining a relatively simple overall structure.
Solution Approach 2:
The telescopic bridge employs a nested sleeve configuration where one sleeve is positioned within another. This nesting arrangement allows the bridge to extend or retract by sliding the inner sleeve relative to the outer sleeve, achieving length adjustment without significantly increasing structural complexity.
2Adaptability or versatility
If the bridge is made adjustable to fit various window thicknesses, then adaptability improves, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The adjustment mechanism is designed to be user-operable without requiring external tools or complex actuation systems. The gear assembly can be manually operated to slide the telescopic sleeves, allowing users to adjust the bridge length themselves during installation or maintenance.
Solution Approach 2:
The patent replaces complex motorized or automated adjustment systems with a simple mechanical gear assembly. This mechanical substitution reduces device complexity while maintaining the adjustability function, making the system more reliable and easier to manufacture.
3Adaptability or versatility
If a telescopic mechanism is added to adjust bridge length, then versatility improves, but the manufacturing complexity increases
Solution Approach 1:
The bridge is divided into separate modular components - the outer sleeve, inner sleeve, and gear assembly. Each component can be manufactured independently using standard machining processes, then assembled together. This segmentation simplifies manufacturing by allowing specialized production of each part and easier quality control.

AI summary
A saddle window air conditioner includes an interior casing and an exterior casing. A bridge extends between the interior casing and the exterior casing. A first sleeve of the bridge is slidably received within a second sleeve of the bridge such that a length of the bridge between the interior casing and the exterior casing is adjustable by sliding the first sleeve within the second sleeve. The saddle window air conditioner also includes a gear assembly mounted within the bridge. The first sleeve is slidable within the second sleeve by rotating the gear assembly.
