Solution Overview
Problem
Existing air intake ventilators have complex designs that interfere with window constructions, require additional insulation, and increase size and weight, especially in buildings with concrete lintels and cold climates, leading to inefficient thermal energy consumption.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a complex design with multiple components and insulation layers is used, then thermal insulation performance is improved, but device complexity and size increase
Solution Approach 1:
The patent employs a flexible shell made of resilient material with good heat insulation properties that forms the housing of the ventilator. This single flexible component replaces complex multi-layer insulation structures, providing both structural integrity and thermal insulation while reducing overall device complexity and weight.
Solution Approach 2:
The patent uses composite material construction by combining resilient heat-insulating material with rigid structural elements (such as the horizontal partition and profiled ribs) to create a hybrid structure that provides both thermal insulation and mechanical strength without requiring separate insulation layers.
2Loss of energy
If additional insulation and complex components are added, then thermal insulation is improved, but weight and size increase
Solution Approach 1:
The flexible shell provides thermal insulation without the weight penalty of traditional rigid insulation materials. Its thin-film nature allows it to provide adequate insulation while keeping the ventilator lightweight and easy to install.
Solution Approach 2:
The patent changes the material parameters by using resilient materials with good heat insulation properties, which have higher thermal resistance per unit weight compared to traditional insulation materials, thereby reducing overall weight while maintaining or improving insulation performance.
3Ease of repair
If a modular design with replaceable components is used, then ease of repair and development is improved, but device complexity increases
Solution Approach 1:
The patent divides the ventilator into distinct modular components including the flexible shell, horizontal partition, profiled ribs, and closure elements that can be independently manufactured, assembled, and replaced. This segmentation enables easy maintenance and development while the standardized connection methods keep the overall structure simple.
Solution Approach 2:
The flexible shell serves multiple functions simultaneously: it provides structural housing, thermal insulation, and a mounting surface for other components. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall complexity while maintaining modularity.
