Window Assembly Peripheral Belt Insulation Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window assemblies with external thermal insulation often reduce light passage and insulating power due to obstructive designs, and can lead to water infiltration issues, compromising energy efficiency and comfort.
Innovation Solution
An assembly for window renovation that integrates the thermal insulation layer into a peripheral belt with a deflector and water-evacuation cap, allowing for increased light passage and improved insulation, while directing rainwater away from the building to prevent infiltration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the box is positioned to block one end of the pre-frame, then light blocking function is achieved, but light passage is reduced
Solution Approach 1:
The box is repositioned from obstructing the light path to being integrated into the peripheral belt structure, where it blocks light from the sides rather than from the front. This dimensional change in positioning allows the light blocking function to be maintained while eliminating the obstruction to light passage through the window tunnel.
Solution Approach 2:
The peripheral belt acts as an intermediary structure that integrates both the insulation layer and the box. This intermediary structure allows the box to perform its light blocking function while being positioned in a way that does not obstruct the light path through the window tunnel, thus resolving the contradiction between light blocking and light passage.
2Object-affected harmful factors
If the means for light blocking are deployed near the window, then light blocking is effective, but insulating air space is reduced
Solution Approach 1:
The means for light blocking are repositioned from the immediate vicinity of the window to the peripheral belt structure. This dimensional change in positioning allows the light blocking function to be maintained while creating sufficient insulating air space between the window and the light blocking means, thus resolving the contradiction between light blocking effectiveness and insulating capacity.
3Ease of manufacture
If the pre-frame is inserted into the window tunnel, then window installation is achieved, but water infiltration risk increases
Solution Approach 1:
The peripheral belt merges multiple functions into a single integrated structure: it provides the framework for inserting the pre-frame into the window tunnel, integrates the external insulation layer, incorporates the box for light blocking, and includes the deflector for water management. This merging eliminates the need for separate components and connections that could create infiltration pathways, thus resolving the contradiction between installation ease and water infiltration prevention.
Solution Approach 2:
The peripheral belt acts as an intermediary structure between the window tunnel and the external environment. It provides a continuous protective barrier that prevents water infiltration while facilitating the insertion and installation of the pre-frame and other components, thus resolving the contradiction between installation ease and water infiltration prevention.
4Loss of energy
If peripheral insulation is integrated into the pre-frame, then insulation continuity is improved, but water infiltration can degrade the insulation
Solution Approach 1:
The deflector acts as an intermediary structure that intercepts rainwater before it can reach and degrade the peripheral insulation. By positioning the deflector to rest against the wall and direct water away from the insulation, it protects the insulation's integrity while maintaining its continuous insulating function, thus resolving the contradiction between insulation continuity and water infiltration prevention.
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
Enhances light passage and insulation efficiency, preventing water damage and maintaining energy savings by ensuring effective rainwater management and airtight sealing, allowing for easy installation and maintenance.
Implementation Method 1
a deflector (231) designed to rest against the wall in order to direct rainwater running down the wall towards the box
Implementation Method 2
the upper portion of the peripheral belt includes a cap having openings intended to evacuate runoff water from the deflector
Implementation Method 3
the pre-frame comprises a peripheral belt into which the external thermal insulation layer is intended to be integrated
Implementation Method 4
When the shutter is lowered, an air gap is created between the window and the shutter, limiting the penetration of cool or warm air from the outside
