Adjustable Insulating Cover for Airtight A/C Wall Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioning units, whether sleeve-mounted or window-mounted, are a significant source of heat loss during cold months due to air leakage, with conventional sealing methods failing to create an airtight seal, leading to increased energy consumption and expenses.
Innovation Solution
An adjustable insulating cover device comprising corner pieces, side walls, and fasteners that can be customized to fit various A/C unit sizes and openings, using multiple layers and attachment devices like magnets or sticky surfaces to secure the cover, ensuring a tight seal and adjustable dimensions to accommodate different equipment and openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional sealing methods (caulk, foam strips) are used to seal around A/C units, then some air leakage is reduced, but air gaps between the sleeve interior and A/C unit remain, allowing cold air to enter
Solution Approach 1:
The cover is divided into multiple segments including a first cover portion that fits over the A/C unit and a second cover portion that fits over the sleeve opening, with insulation material positioned between them. This segmentation allows each portion to address specific leakage paths independently, with the first portion sealing around the A/C unit and the second portion sealing the sleeve opening, eliminating the need for a single complex seal.
Solution Approach 2:
Insulation material is introduced as an intermediary element between the first and second cover portions. This insulation material fills the gap between the A/C unit and the sleeve interior, preventing cold air from flowing through the gap while the cover portions provide the primary sealing structure. The intermediary insulation material addresses the specific problem of air gaps that conventional sealing methods cannot eliminate.
2Loss of energy
If pillows, roll plastic, or textile covers are used to cover A/C units, then some insulation is provided, but the seal between the product and sleeve or window is not airtight, allowing outside air to flow inside
Solution Approach 1:
The cover system is segmented into a first cover portion that directly contacts and seals around the A/C unit exterior surfaces, and a second cover portion that seals the sleeve opening. This segmentation ensures that the seal addresses both the A/C unit interface and the sleeve interface separately, creating a more reliable airtight seal compared to single-piece covers that must accommodate both interfaces simultaneously.
Solution Approach 2:
The cover portions are designed with flexible materials that can conform to the irregular surfaces of the A/C unit and sleeve opening. This flexibility allows the cover to create an airtight seal around the A/C unit without rigid structures, while the insulation material provides the necessary thermal barrier. The flexible design overcomes the limitation of rigid conventional covers that cannot adapt to various A/C unit shapes and sizes.
3Ease of manufacture
If a fixed-size cover is used for A/C units, then manufacturing is simplified, but it cannot accommodate different A/C unit sizes and opening dimensions
Solution Approach 1:
The cover system incorporates adjustable elements including expandable insulation material and flexible cover portions that can be adjusted during installation to accommodate different A/C unit sizes and sleeve opening dimensions. The insulation material can be compressed or expanded to fill varying gaps, and the flexible cover portions can be stretched or folded to fit different geometries, providing adaptability while maintaining relatively simple manufacturing processes.
Solution Approach 2:
The cover system utilizes materials and design features that allow parameter changes during installation, such as adjustable thickness of insulation material, flexible dimensions of cover portions, and variable compression levels. These parameter changes enable the same cover design to adapt to different A/C unit sizes and opening dimensions without requiring multiple fixed-size cover variants, balancing manufacturing simplicity with versatility.

AI summary
Embodiments disclose an apparatus for enclosing and insulating an opening in a structure such as an air conditioning unit mounted in a sleeve. The apparatus includes one or more layers required depending on the distance which any equipment installed in the opening extends beyond the wall surface. An embodiment for a rectangular insulating cover apparatus includes corner pieces, horizontal wall pieces, and side wall pieces. Corner pieces are configured to allow the horizontal wall pieces and side wall pieces to be slid into the corner pieces. The depth of the insertion into the corner pieces can be varied depending on the desired dimensions for the insulating cover apparatus. After cutting the top cover the required dimensions for the opening in the insulating cover apparatus, top cover corner boots and C-channels are installed on the top cover which is then pressed into place. A method for assembling and installing the same is provided, as are other aspects.
