Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for hinges on hollow profiles of windows and doors are complex, costly, require pre-installation, take time and skill to assemble, and occupy significant storage space, with limited adaptability and stability issues due to size and design constraints.
Innovation Solution
A clamping anchor with a hook-shaped or L-shaped body featuring an internal screw thread and broadened head, allowing for easy installation and removal, adaptable to various profile configurations, and providing stable fastening without pre-installation, using a compact design that maximizes the clamping surface area with minimal hole size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamping system is used to secure fittings on hollow profiles, then stable fastening is achieved, but the construction becomes complex and cost increases
Solution Approach 1:
The clamping anchor is divided into two functional parts: an L-shaped body that provides the clamping function and a separate screw thread that provides the fastening function. This segmentation allows each part to be optimized independently, simplifying the overall construction while maintaining stable fastening.
Solution Approach 2:
The L-shaped body serves multiple functions: it acts as a clamping element, provides a mounting surface for fittings, and incorporates a screw thread for secure fastening. This multi-functionality eliminates the need for separate clamping and fastening components, reducing construction complexity.
2Reliability
If traditional fastening elements are used, then stable mounting is achieved, but significant storage space is required and many different types must be kept in stock
Solution Approach 1:
The L-shaped clamping anchor with integrated screw thread is designed to be universally applicable to various hollow profile types and fitting configurations. This single standardized design replaces the need for multiple specialized fastening elements, significantly reducing storage space requirements and inventory complexity.
Solution Approach 2:
The clamping anchor design allows for parameter variations (such as size, thread type, and L-shape dimensions) to be adjusted for different applications, enabling a single basic design to serve multiple purposes across different profile types and fitting sizes.
3Manufacturing precision
If fastening elements are pre-installed during profile assembly, then proper positioning is ensured, but the process requires additional time and skilled mechanics
Solution Approach 1:
The L-shaped clamping anchor is designed to be pre-positioned in the hollow profile during assembly, ensuring proper positioning before the actual fastening operation. This preliminary placement guarantees accurate positioning while simplifying the subsequent fastening step, reducing the need for skilled adjustment work.
Solution Approach 2:
The clamping anchor's L-shaped body automatically positions itself within the hollow profile structure, with the right angle ensuring proper orientation and placement. This self-positioning capability eliminates the need for complex alignment procedures and skilled manual adjustment, reducing assembly time and skill requirements.
4Adaptability or versatility
If a clamping anchor with recesses is used to allow moving parts, then the parts can move in relation to one another, but the construction becomes complex and the visible part becomes large
Solution Approach 1:
The clamping anchor incorporates a movable screw thread that can rotate and engage with the L-shaped body, allowing the fitting to be securely fastened while maintaining the ability to be adjusted or removed. This dynamic mechanism provides moving part capability without requiring complex recesses, simplifying the construction while maintaining adaptability.

Function Achieved in This Case
The solution enables efficient, cost-effective, and time-saving assembly of hinges on hollow profiles with enhanced stability and adaptability, allowing for easy installation and removal, and reduced storage needs, while maintaining a strong and aesthetically pleasing fastening solution.
Implementation Method 1
a broadened head (10) on the end face of said leg (8), whereby the clamping anchor has such a shape and dimensions that the body (6), starting with the first leg (7), can be put entirely through an opening (11) in a wall (12) of the profile up to the broadened head (10) which is such that it cannot pass through the above-mentioned opening (11)
Implementation Method 2
the second leg (8) is provided with an internal screw thread (9) extending in the longitudinal direction of said leg (8)... the clamping anchor can then be clamped with the latter thanks to the tensile strength of a bolt which is screwed in the above-mentioned screw thread (9)
Implementation Method 3
the clamping anchor can then be clamped with the latter thanks to the tensile strength of a bolt which is screwed in the above-mentioned screw thread (9)
Implementation Method 4
the length of the second leg (8) is such that when the body (6) is put in the profile up to the broadened head (10), the clamping anchor can be hooked with the first leg (7) behind a first inner wall surface (13) of the profile
