Sliding Window Fitting Assembly with Collision-Based Sequence Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window or door fitting assemblies often result in operating errors, particularly when users are unfamiliar with the sequence of closing two leaves, leading to frequent damage due to incorrect operation.
Innovation Solution
A fitting assembly with a first and second connecting-rod assembly, featuring a first projection that collides with a second projection when the leaves are slid together, ensuring the passive leaf is closed before the active leaf, preventing complete closure and thus preventing damage and ensuring correct operation.

Engineering Contradiction Analysis
1Productivity
If the user closes the active leaf first without proper guidance, then the closing operation is completed quickly, but damage occurs to the seal or locking mechanism due to incorrect operation sequence
Solution Approach 1:
The first projection on the inactive leaf and second projection on the active leaf are positioned to collide before the leaves can be fully closed in the wrong sequence. This preliminary collision prevents the harmful action of forcing the leaves together incorrectly, thereby protecting the seal and locking mechanism while still allowing quick closing when the correct sequence is followed
Solution Approach 2:
The projection collision mechanism acts as an intermediary between the two leaves during closing operations. When the incorrect sequence is attempted, the projections collide and physically block further movement, serving as a mediator that prevents damage without requiring complex control systems or user awareness
2Reliability
If the passive leaf must be closed first with coordinated end-face contours or locking strikers, then damage is prevented, but the operating complexity increases and users unfamiliar with the sequence make errors
Solution Approach 1:
The fitting assembly is self-regulating through the projection collision mechanism. The system automatically enforces the correct closing sequence without requiring the user to know or remember any specific procedure. The projections themselves provide the guidance and restriction, making the system self-service and eliminating the need for user education or training
Solution Approach 2:
The projections are pre-positioned on the leaves during manufacturing. The first projection on the inactive leaf and second projection on the active leaf are arranged in advance to automatically collide if the wrong closing sequence is attempted, providing preliminary guidance before the actual closing action occurs and preventing errors before they can cause damage

AI summary
A fitting assembly has a device for securing against operating errors that has a first protrusion which can be moved relative to a second protrusion by means of a first operating rod assembly. A buffer can be provided between the end sides of the first protrusion and the second protrusion. The first protrusion can be a cylinder and/or the second protrusion can extend in an elongated manner. The fitting assembly can have an anti-lifting device with a third protrusion which prevents a lifting of the first leaf. The fitting assembly has multiple carriages and multiple sliders in order to position leaves of the window or the door into their slide position in parallel with the main plane of the window or the door. In the blocking position, the leaves can be pressed against a fixed frame of the window or the door via the fitting assembly with multiple carriages and multiple sliders, in order to reliably seal the window or the door.
