Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional room air conditioning units are noisy, costly, and require professional installation, and when installed in windows, they obstruct natural light and fresh air, cause window damage, and are limited to multi-story installations due to balance issues and inflexible mounting solutions.
Innovation Solution
A modular air conditioning unit with two independent containers suspended over a support surface via an adjustable frame, using flexible piping and hermetic snap connectors, allowing for adjustable gap width and separate servicing, and restoring the functionality of the windowsill as a shelf.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the air conditioning unit is installed in a window, then the unit can be easily installed without making holes in the wall, but the window is obstructed from providing natural light and fresh air, and the windowsill is covered
Solution Approach 1:
The air conditioning unit is divided into two separate containers: an interior container housing the evaporator coil and fan, and an exterior container housing the condenser coil and compressor. This segmentation allows the interior container to be installed inside the room without obstructing the window opening, while the exterior container is mounted outside on the wall or window frame, thereby preserving natural light and fresh air access while maintaining installation ease
Solution Approach 2:
The solution moves the noisy compressor and condenser coil to the exterior dimension (outside the room), while keeping the evaporator coil and fan inside the room. This dimensional separation allows the interior unit to be positioned without blocking the window opening, thus preserving illumination and ventilation while maintaining the cooling function
2Loss of time
If the air conditioning unit is installed in a window, then the unit can be quickly installed, but permanent damage is left to the window
Solution Approach 1:
By separating the unit into interior and exterior containers, the exterior container can be mounted on the wall or window frame using brackets that do not require drilling holes in the window pane itself. The interior container is simply positioned inside the room, preserving window integrity while maintaining quick installation
Solution Approach 2:
The invention introduces an intermediary mounting structure (brackets and frame) that connects the exterior container to the wall or window frame without requiring direct attachment to the window pane. This intermediary system distributes the mounting stress away from the window, preventing damage while enabling quick installation
3Adaptability or versatility
If the air conditioning unit is installed in a building with more than a couple of floors, then cooling can be provided to upper floors, but the unit cannot be installed without a special wall port due to balance issues
Solution Approach 1:
Dividing the unit into two containers allows the heavier exterior container (housing the compressor) to be mounted securely outside on the wall or window frame, while the lighter interior container is positioned inside the room. This segmentation resolves balance issues for multi-floor installations by distributing weight appropriately, eliminating the need for special wall ports while maintaining installation simplicity
Solution Approach 2:
The exterior container serves as a counterweight structure, housing the heavy compressor and condenser coil outside, which balances the overall unit configuration. This allows the interior container to be positioned inside the room without creating instability or balance issues that would prevent multi-floor installation
4Object-affected harmful factors
If the noisy components are placed in a separate unit outside, then the noise problem is resolved, but the cost of the unit, installation, and operation increases
Solution Approach 1:
The unit is segmented into two containers connected by flexible piping, allowing the noisy compressor and condenser coil to be located outside while the evaporator coil and fan remain inside. This segmentation reduces noise inside the room while maintaining a relatively simple system that can be installed by consumers without requiring professional HVAC technicians or complex infrastructure
Solution Approach 2:
The invention uses flexible refrigerant piping to connect the interior and exterior containers, replacing rigid piping that would require professional installation. This flexible connection method simplifies the system complexity while effectively separating the noisy components outside from the quiet components inside, reducing noise without increasing operational complexity
