Solution Overview
Problem
Window air conditioners with a saddle-shaped design have an indoor unit positioned low, affecting cooling and heating efficiency due to the air outlet location, and noise isolation measures compromise operational quietness.
Innovation Solution
The indoor unit is equipped with a sliding assembly and locking mechanism allowing adjustment of the air outlet height, enhancing cooling and heating efficiency by directing air flow as needed, while maintaining noise isolation through a saddle-shaped design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the indoor unit is positioned low in a saddle-shaped design, then noise isolation is improved, but cooling and heating efficiency deteriorates due to air outlet location
Solution Approach 1:
The patent applies the dynamics principle by making the indoor unit movable rather than fixed. The sliding assembly allows the indoor unit to move vertically along the connecting device, enabling dynamic adjustment of the air outlet height. This resolves the contradiction by allowing the system to maintain low position for noise isolation while periodically adjusting to optimal heights for cooling/heating efficiency.
Solution Approach 2:
The patent changes the positional parameter of the indoor unit from fixed to adjustable. By implementing a sliding mechanism with locking assemblies, the air outlet height can be changed between different positions (first position for noise isolation, second position for optimal air flow). This parameter change enables the system to switch between noise isolation mode and efficiency mode as needed.
2Device complexity
If the air outlet position is fixed, then device complexity is reduced, but adaptability deteriorates for different cooling and heating requirements
Solution Approach 1:
The patent segments the air outlet positioning function into discrete adjustable positions rather than continuous movement. The locking assembly provides specific first and second positions, creating segmented positioning options. This maintains relatively simple structure while providing adaptability for different cooling and heating requirements through multiple discrete positions.
Solution Approach 2:
The sliding assembly with locking mechanism serves multiple functions: it enables vertical movement for position adjustment, provides locking at specific positions for stability, and allows easy transition between positions. This multi-functional design achieves adaptability without proportionally increasing device complexity.

AI summary
A window air conditioner includes an outdoor unit, an indoor unit and a connecting device. The connecting device includes a third housing, and the third housing is connected to a first housing and a second housing. The second housing is movable relative to the third housing in a first predefined direction in order to adjust a position of the indoor unit. The connecting device further includes at least one cooperating assembly connected to the third housing. The indoor unit further includes at least one locking assembly connected to the second housing. The at least one locking assembly is configured to cooperate with the at least one cooperating assembly for locking when the second housing moves to a first position in the first predefined direction, in order to limit a position of the second housing and position the air outlet at a predefined height.
