Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door fitting systems face challenges in coupling components with shallow fitting grooves, requiring significant installation space and limited adjustability, especially when trying to couple very flat fitting parts.
Innovation Solution
A method involving a pivoting movement where the first fitting part passes under a U-leg of a U-shaped spring element, allowing the toothings to align and engage without needing movable components, utilizing a U-shaped spring element to facilitate assembly and adjustability within a shallow groove.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pivoting movement is used to couple fitting components, then the coupling reliability is improved, but the installation space requirement increases
Solution Approach 1:
The patent applies the dynamics principle by enabling the first fitting component to perform a pivoting movement during assembly. This dynamic approach allows the component to transition from a parallel position to an engaged position, ensuring reliable toothed connection while accommodating space constraints through controlled motion rather than static configuration.
Solution Approach 2:
The patent utilizes dimensionality change by introducing a rotational/pivoting dimension to the assembly process. Instead of relying solely on linear insertion, the first fitting component pivots around a point, allowing engagement in a different spatial dimension. This resolves the contradiction by achieving reliable coupling through angular displacement rather than increasing linear installation space.
2Area of stationary object
If the fitting groove depth is reduced to save space, then the space efficiency is improved, but the height of the toothed shoe becomes minimal
Solution Approach 1:
The patent overcomes the geometric constraint of minimal toothed shoe height by introducing a dynamic pivoting movement. Even when the shoe height is minimal due to shallow groove depth, the pivoting action allows the first fitting component to achieve proper engagement angle and force distribution, maintaining functional effectiveness despite reduced static dimensions.
Solution Approach 2:
The patent changes the operational parameters by transitioning from static engagement to dynamic pivoting engagement. This parameter change allows the system to achieve reliable coupling with minimal toothed shoe height, as the pivoting motion provides the necessary mechanical advantage and alignment without requiring increased structural height.
3Adaptability or versatility
If movable mounting is used for fitting components, then the adjustability is improved, but the device complexity increases
Solution Approach 1:
The patent achieves adjustability through a simple pivoting movement rather than complex movable mounting mechanisms. The first fitting component can pivot during assembly to accommodate angular misalignments and achieve proper engagement, providing adaptability without requiring multiple adjustment mechanisms or complex mounting structures.
Solution Approach 2:
Instead of making components movable during operation, the patent inverts the approach by making the assembly process dynamic through pivoting. The components themselves remain structurally simple and fixed in design, but the assembly method provides the necessary adaptability through controlled pivoting motion, reversing the traditional approach of using movable components for adjustment.

Function Achieved in This Case
Enables reliable coupling of flat fitting parts in shallow grooves with enhanced adjustability and space-saving design, ensuring secure engagement and alignment of toothings for flexible assembly and operation.
Implementation Method 1
A further development of the invention provides that the retaining leg is a U-shaped leg of a U-shaped spring element. This promotes elastic deformation of the retaining leg, which springs back into shape after deformation, thus saving space.

AI summary
The invention relates to a method for mounting a fitting of a window or of a door, in which the fitting has two tooth systems (12, 13, 17, 18), which are to be brought into engagement with one another, on fitting parts (1, 2) which are to be coupled to one another, wherein a first of the fitting parts (2) can be tilted with respect to the second fitting part (1), the fitting parts (1, 2) which are to be coupled and which comprise the tooth systems (12, 13, 17, 18) are guided towards one another and are brought into bearing contact and then the tooth systems (12, 13, 17, 18) are brought into engagement with one another by means of a pivoting movement. Simple and reliable coupling is to be achieved even given a small installation space in that the first fitting part (2) has a U-shaped engagement portion over which a holding leg (21) partially engages.
