Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing window or door sashes, such as conventional blocking and adhesive technology, lack versatility and efficiency in meeting customer needs, as they require different profile elements for each production method, increasing complexity and costs for manufacturers.
Innovation Solution
A profile element with a multifold design, featuring a fold base divided into three sections, allowing for both blocking and adhesive production, combined with a centering element that includes a plate-shaped base body with mounting webs and springs for secure glazing centering, enabling the same profile to be used for various production methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If different profile elements are used for blocking and adhesive production methods, then each production method can be optimized, but the device complexity and storage requirements increase
Solution Approach 1:
The profile element is designed with a multi-functional fold base that can accommodate both blocking and adhesive production methods. The fold base includes a first section with an inclined course for blocking integration, a second section with perpendicular profile for adhesive application, and a third section providing additional support. This allows a single profile element to serve multiple production purposes, reducing the need for different specialized profiles.
Solution Approach 2:
The fold base is divided into three distinct sections, each optimized for specific functions. The first section integrates with blocking, the second section provides a perpendicular surface for adhesive application, and the third section offers additional support. This segmentation allows the single profile element to accommodate multiple production methods simultaneously through differentiated zones.
2Adaptability or versatility
If multiple profile elements are maintained for different production methods, then customer needs can be met, but storage complexity and costs increase
Solution Approach 1:
The profile element combines features required for both blocking and adhesive production into a single universal component. The fold base's multi-section design enables it to function in both production methodologies, allowing manufacturers to maintain a reduced inventory of profile elements while still meeting diverse customer requirements for different production preferences.
3Device complexity
If a single profile element is used for both blocking and adhesive production, then storage complexity is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The fold base is segmented into three sections with distinct geometric characteristics. The first section has an inclined course optimized for blocking integration, the second section has a perpendicular profile for adhesive application, and the third section provides additional support. This segmentation allows each zone to be optimized for its specific function while maintaining overall manufacturability through standardized production processes.
Solution Approach 2:
Different sections of the fold base have locally optimized geometries suited to their specific functions. The inclined first section facilitates blocking integration, while the perpendicular second section enables precise adhesive application. This local quality approach allows high manufacturing precision to be achieved only where critically needed, rather than uniformly across the entire profile.
4Strength
If conventional blocking method is used, then structural strength is achieved, but adaptability to different production preferences is limited
Solution Approach 1:
The profile element maintains the structural strength benefits of conventional blocking through its first section design, while simultaneously providing the flexibility to accommodate adhesive production methods through its second and third sections. This multi-functionality allows the same profile to satisfy both structurally-oriented customers preferring blocking and those preferring adhesive technology.
5Adaptability or versatility
If adhesive technology is used, then production flexibility is improved, but manufacturing precision requirements increase
Solution Approach 1:
The fold base is segmented to provide a dedicated second section with a perpendicular profile specifically optimized for adhesive application. This segmentation concentrates the precision requirements to a specific zone rather than distributing them throughout the entire profile, making the precision requirements more manageable during manufacturing while maintaining overall production flexibility.

Function Achieved in This Case
The multifold profile element and centering element combination simplifies production, reduces storage complexity, and provides a cost-effective solution by enabling the same profile to be used for both conventional blocking and adhesive technologies, enhancing the manufacturer's ability to meet diverse customer requirements.
Implementation Method 1
at least one centering spring, which rises up in the first section relative to the plane of the plate and is designed in such a way that it causes a restoring force in the opposite direction when a load is applied in the direction of the plane of the plate
Implementation Method 2
