Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile systems for intersecting joints require tight tolerances for secure and detachable connections, making production more difficult and expensive.
Innovation Solution
A profile system comprising elongate profiles with constant cross-sections, intermediate and/or end elements, and connecting pins. The connecting pins have a radially outwardly domed clamping section and a receiving section with an annular indentation, allowing for a positive and frictional connection without requiring tight tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tight tolerances are used for secure and detachable connections in existing profile systems, then connection reliability is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the geometric parameters of the connecting pin by introducing a radially outwardly domed clamping section with an elongate recess. This parameter change allows the pin to produce both positive and frictional connections without requiring tight manufacturing tolerances, thus improving connection reliability while reducing manufacturing complexity
Solution Approach 2:
The connecting pin features a radially outwardly domed clamping section, which is a curved/spheroidal geometry. This curvature allows the pin to deform elastically during insertion and create a frictional connection with the receiving opening, enabling reliable connections without tight tolerances
2Strength
If tight tolerances are used for secure connections, then connection strength is improved, but production cost increases
Solution Approach 1:
By modifying the geometric parameters of the connecting pin to include a domed clamping section with a recess, the patent achieves strong frictional connections without requiring tight tolerances, thereby reducing production costs while maintaining connection strength
Solution Approach 2:
The connecting pin is designed as a simple, easily manufacturable component that can be produced with standard tolerances. The pin serves its connection function reliably and can be replaced if needed, reducing overall production costs
3Reliability
If complex connection mechanisms are used to achieve releasable connections, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complexity from the connection mechanism by using a simple connecting pin with a domed clamping section. The reliability is achieved through the frictional connection created by the domed geometry, eliminating the need for complex locking mechanisms or multiple components
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
The system enables easy and cost-effective assembly of components with a reliable yet releasable connection, reducing production complexity and costs.
Implementation Method 1
The dimensions of the clamping section (17) can be adapted to the dimensions of the receiving openings (5) in such a manner that the clamping section (17) can be inserted into a receiving opening (5) while producing a positive and frictional connection

AI summary
A profile system includes a series of elongate profiles, the elongate profiles each having: a contact section (4) extending along the length of the profile, the contact section having a lateral edge against which end faces of tiles can rest. The contact section has a face side with receiving openings (5) receiving a first end portion (15) of a connecting pin (14), the receiving openings extending into the contact section parallel to the length of the profiles. A fastening section (3) extends at a 90-degree angle away from the contact section, the fastening section provided with punched holes (2), the punched holes enabling fixing of the profile to a substrate, the fastening section providing a shelf upon which a tile can be installed aside the contact section while the end faces of the tile rest against the lateral edge of the contact section.
