Espagnolette Corner Guide Perpendicular Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner drives for windows and doors face challenges in easily replacing movable functional elements, leading to sluggish coupling and limited space for assembly, with existing solutions either not allowing for exchange of locking elements or requiring complex separate units.
Innovation Solution
A corner guide design where the additional structural unit is fed in perpendicular to the first leg, featuring a base plate with a sliding element that is longitudinally movable and positively connected to the coupling element, allowing for easy assembly, disassembly, and exchange of movable functional elements, with a form-fitting connection simplifying assembly and increasing reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a slide guided in the first leg is used to switch the coupling element into form-fitting connection, then the coupling element can be connected, but the guide between slide and leg requires very high precision and causes sluggishness when coupling
Solution Approach 1:
The invention divides the additional structural unit into separate components: a base plate that can be mounted stationarily on the wing, and a sliding element that is guided longitudinally movable in a slot on the base plate. This segmentation allows each component to be manufactured and assembled independently, reducing the precision requirements for the overall assembly while maintaining reliable form-fitting connection through the pin-like extension and cavity interface.
2Ease of manufacture
If the additional structural unit is fed in from a direction parallel to the first leg, then assembly is straightforward, but the space for movable functional element is very limited
Solution Approach 1:
The invention changes the assembly direction from parallel to perpendicular relative to the first leg. The additional structural unit is fed in from a direction perpendicular to the first leg, which opens up additional space for accommodating movable functional elements while still allowing for straightforward assembly through the perpendicular insertion path.
3Reliability
If a complex separate additional unit with connecting bolt is used for form-fitting connection, then connection is achieved, but the device complexity increases and locking element cannot be exchanged
Solution Approach 1:
The invention creates a universal additional structural unit with a base plate and sliding element that can accommodate different movable functional elements (such as locking elements, brakes, or other mechanisms). The standardized interface with the coupling element allows various functional elements to be exchanged without replacing the entire additional unit, reducing device complexity while maintaining connection reliability.
4Ease of operation
If the sliding element is guided in a slot on the base plate, then the additional structural unit can be easily assembled and disassembled, but the coupling element must be precisely positioned
Solution Approach 1:
The invention incorporates a pin-like extension on the sliding element that is designed to penetrate into a cavity on the coupling element during the assembly process. This preliminary form-fitting connection guides the coupling element into the correct position as the additional structural unit is fed in perpendicular to the first leg, ensuring precise positioning is achieved automatically during assembly rather than requiring separate precision alignment steps.
