Facade Frame with Resilient Profile Beam for Timber Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Timber frame construction is hindered by the time-consuming and costly process of installing chambranles for windows and doors at construction sites, which also compromises weather isolation and structural protection.
Innovation Solution
A facade frame design that allows glass panels or doors to be directly placed against a U-shaped profile beam at the factory, eliminating the need for chambranles, featuring a resilient element connecting strips to facilitate assembly and enhance weather protection, using aluminium profile beams for improved durability and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a chambranle is placed in the facade frame at the construction site, then glass panels or doors can be installed, but the building assembly time increases and construction costs increase
Solution Approach 1:
The profile beam is pre-formed with an integrated groove and resilient element structure during factory manufacturing, so that the glass panel or door can be directly placed against the profile beam at the construction site without requiring additional chambranle installation steps. This preliminary preparation of the mounting structure eliminates the need for on-site chambranle placement, thereby reducing building assembly time while maintaining ease of glass panel or door installation.
2Ease of manufacture
If a chambranle is placed in the facade frame, then glass panels or doors can be installed, but the isolation of the building deteriorates and weather protection is reduced
Solution Approach 1:
The profile beam integrates multiple functions into a single component: it provides the structural support for glass panels or doors, creates the groove for positioning, and incorporates the resilient element for sealing. By merging the chambranle function with the profile beam structure, the solution eliminates the need for separate chambranle components that would compromise isolation, thereby maintaining both ease of installation and building weather protection.
Solution Approach 2:
The resilient element acts as an intermediary sealing component between the profile beam and the glass panel or door, providing weather tightness and isolation. This intermediary element ensures that the direct connection between the profile beam and glass panel maintains both structural integrity and weather protection, eliminating the need for additional chambranle layers that would compromise isolation.
3Object-affected harmful factors
If a U-shaped profile beam with resilient element is used, then weather protection and isolation are improved, but the device complexity increases
Solution Approach 1:
The profile beam is segmented into distinct functional strips: a first strip for structural support, a second strip forming the groove, and a third strip with the resilient element. This segmentation allows each component to perform its specific function while maintaining overall structural integrity. The resilient element is further divided into fourth and fifth strips that can move relative to each other, providing flexibility without excessive complexity.
Solution Approach 2:
The resilient element is designed with movable strips (fourth and fifth strips) that can move away from each other to allow the profile beam to be opened temporarily for installation, and then return to their original position to provide sealing. This dynamic capability allows the structure to adapt during assembly while maintaining weather protection when closed, managing complexity through functional flexibility rather than rigid multi-component design.
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
This approach accelerates building assembly, improves thermal isolation, and enhances protection against weather influences, reducing construction costs and time while maintaining structural integrity.
Implementation Method 1
The resilient element allows the second strip and the third strip to move away from each other, so the profile beam can be opened temporarily
