Inflatable Window Cushion for Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional window shading systems fail to provide sufficient insulation and airtightness, often requiring manual deployment and bulky tracks, which are inefficient and aesthetically unpleasing.
Innovation Solution
An inflatable window-covering system with a drive assembly, including sensors, a microcontroller, and an air pump, that inflates or deflates a cushion to cover the window based on temperature, light, or user input, eliminating the need for tracks and ensuring complete coverage without obstructing the window when retracted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional shading systems are used to block sunlight, then heat transfer through windows is reduced, but the systems do not provide sufficient insulation or airtightness to noticeably prevent heat transfer
Solution Approach 1:
The patent uses an inflatable cushion filled with air to create a sealed barrier over the window. The air pressure within the cushion provides both structural support and sealing force against the window frame, achieving reliable insulation and airtightness through pneumatic pressure rather than rigid mechanical structures.
Solution Approach 2:
The invention employs a flexible inflatable cushion that can conform to the window frame and seal against irregular surfaces. This flexible membrane structure provides effective thermal and air sealing by adapting to the window geometry, overcoming the limitations of rigid conventional shades.
2Loss of energy
If thicker window-covering material is used to provide better insulation, then heat transfer is reduced, but manual deployment or tracks are required which are obtrusive and inefficient
Solution Approach 1:
The patent replaces complex mechanical deployment systems (tracks, manual mechanisms) with a simple inflatable structure. The cushion is deployed by inflating it with air, eliminating the need for obstructive tracks or complicated mechanical systems while providing effective window coverage and insulation.
Solution Approach 2:
The invention changes the physical state of the cushion material from deflated (compact) to inflated (expanded) to achieve deployment. This parameter change (volume expansion through air inflation) provides a simple, track-free deployment mechanism that avoids the complexity of traditional mechanical systems.
3Illumination intensity
If conventional shades are used to cover windows, then some sunlight blocking is achieved, but they do not securely seal to the window frame or against window
Solution Approach 1:
The inflatable cushion uses air pressure to create a secure seal against the window frame. The pressurized air within the cushion forces the sealing surfaces against the frame, achieving reliable attachment and airtightness that conventional gravity-dependent shades cannot provide.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively regulates temperature by preventing heat transfer through windows, enhancing energy efficiency and maintaining aesthetic appeal by not requiring tracks, while allowing for automatic deployment and retraction based on environmental conditions.
Implementation Method 1
an air pump, which may be configured to inflate the inflatable cushion based, at least in part, on the detected triggering event
Implementation Method 2
The inflatable cushion may prevent sunlight from entering the building and warming the building to too high of a temperature. If the outside temperature is colder than a desired inside temperature, the inflatable cushion may be inflated to prevent heat inside the building from dissipating through the window.
Data Source
AI summary
An inflatable, window-covering system is described. The inflatable, window-covering system may include an inflatable cushion and a drive assembly, the drive assembly including a power source; one or more sensors, where the one or more sensors may be configured to detect a triggering event; and an air pump configured to inflate the inflatable cushion based, at least in part, on the detected triggering event. In some cases, the triggering event may include any of sensing a predetermined temperature, sensing a predetermined level of light intensity, sensing a predetermined time, or receiving an instruction, or any combination thereof.
