Blind Frame Profile With Detachable Insert Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window frame profiles have complex outer contours due to fixed side webs for fittings and seals, increasing manufacturing effort and costs, and require specialized profiles for different applications, limiting flexibility and storage efficiency.
Innovation Solution
A window frame profile with an L-shaped outer side surface featuring a single side bar, allowing for a continuous contact surface without intermediate webs, and an insert strip that can be detachably attached to hold fittings or glazing beads, enabling versatile use and simplified manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed side webs are provided on the side surfaces to delimit receiving grooves for fittings or seals, then fittings and seals can be securely held, but the outer contour becomes complex and manufacturing effort increases
Solution Approach 1:
The profile is divided into a basic profile part and separate insert strips. The insert strips are detachably inserted into the basic profile to form receiving grooves for fittings and seals. This segmentation allows the basic profile to have a simple, easy-to-manufacture contour while the insert strips provide the necessary functional features for securing components.
Solution Approach 2:
The receiving groove structures are extracted from the main profile body and implemented as separate insert strips. This extraction simplifies the outer contour of the basic profile, making it easier to manufacture, while the insert strips can be added only where needed to provide secure holding for fittings and seals.
2Adaptability or versatility
If specially adapted profiles are kept ready for different purposes, then specific functions are optimized, but storage costs increase
Solution Approach 1:
A universal basic profile is created that can accommodate various fittings, seals, and glazing beads through different combinations of insert strips. Instead of maintaining multiple specialized profiles for different applications, the same basic profile serves multiple functions by accepting different insert strip configurations, thereby reducing storage requirements.
Solution Approach 2:
The profile system becomes dynamic and reconfigurable through the use of detachable insert strips. The basic profile can be adapted to different functional requirements by inserting or removing strips as needed, allowing the same profile to serve multiple purposes across different applications without requiring pre-manufactured specialized variants.
3Ease of operation
If intermediate or separating webs protrude outwards to form fitting grooves, then fittings can be accommodated, but the contact surface is interrupted and mounting area is reduced
Solution Approach 1:
The insert strips are nested within the basic profile structure, being detachably inserted into it. This nesting approach allows the receiving grooves to be formed without protruding intermediate webs that would interrupt the outer contour. The insert strips are contained within the profile's boundary, preserving the continuous contact surface while still providing fitting accommodation capabilities.

AI summary
The profile (1) has an outer profile part (6) connected with an inner profile part (4) via connecting rods (5). An outer side surface (25) of a side wall (24) of the inner profile part is designed in an L-shape with an individual side bar (26) at an outer side or an inner side of the inner profile part. An insertion strip is detachably fastened at the side surface for holding a fitting part or a glass retaining strip. A receiving groove is defined between the side bar and the insertion strip and receives the fitting part or the glass retaining strip.
