Solution Overview
Problem
Existing insulating devices for building openings, such as windows and doors, are not effectively retrofittable and do not provide sufficient thermal insulation to reduce energy consumption in buildings.
Innovation Solution
An insulating device with an airtight surface structure and frame, which can be easily mounted to form a thermally insulating space between the surface structure and the sash, using a foil or transparent film, and adjustable frame components for various sizes, allowing easy retrofitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If existing insulating devices are used, then thermal insulation is provided, but they are not easily retrofittable and do not provide sufficient thermal insulation
Solution Approach 1:
The insulating device is divided into separate components: a frame structure and an airtight surface structure that can be independently manufactured and then assembled. This segmentation enables easy retrofitting as the components can be independently prepared and installed on existing building openings without requiring complex integrated systems.
Solution Approach 2:
The airtight surface structure is implemented as a thin film or foil that can be easily attached to the frame and positioned between the sash and the building frame. This thin film approach provides effective thermal insulation while being simple to install retroactively on existing windows or doors.
2Loss of energy
If an airtight surface structure is added to form an insulating space, then thermal insulation is improved, but device complexity increases
Solution Approach 1:
The airtight surface structure is implemented as a thin film or foil that can be easily attached to the frame and positioned between the sash and the building frame. This thin film approach provides effective thermal insulation while being simple to install retroactively on existing windows or doors.
Solution Approach 2:
The frame structure serves multiple functions: it provides mechanical support for the airtight surface structure, enables positioning relative to the sash, and facilitates attachment to the building frame. This multi-functionality reduces overall device complexity by consolidating multiple components into a single integrated frame element.
