Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of door or window fittings is time-consuming due to the need for screwing a faceplate into a fitting groove, which can be cumbersome and inefficient.
Innovation Solution
A fastening element comprising a base body with a coupling section and resilient latching elements that allows automatic latching into the fitting groove without the need for screwing, featuring a blocking element that moves between release and blocking positions to secure the connection, and can be easily attached to standard faceplates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a faceplate is screwed to the casement frame after insertion into the fitting groove, then the connection is secure and reliable, but the assembly process becomes time-consuming and cumbersome
Solution Approach 1:
The fastening element is divided into distinct functional components: a base body for insertion into the fitting groove, resilient latching elements for automatic engagement with the groove, and a blocking element for securing the latched position. This segmentation allows each component to perform its specific function efficiently, enabling quick assembly without screwing while maintaining connection reliability through the coordinated action of multiple specialized elements.
Solution Approach 2:
The resilient latching elements are designed to automatically engage with the fitting groove when the base body is inserted, eliminating the need for manual screwing operations. The latching mechanism self-activates through the insertion motion itself, and the blocking element automatically secures the latched position, making the entire fastening process self-serving and无需 additional fastening operations.
2Reliability
If a blocking element is added to prevent unintentional release of the latching connection, then the reliability of the connection is improved, but the device complexity increases
Solution Approach 1:
The blocking element is integrated with the resilient latching elements through a predetermined breaking point connection, combining the blocking function with the latching mechanism into a single unified component. This merging approach allows the blocking element to be part of the fastening element assembly without requiring completely separate blocking devices, thus improving latching connection security while minimizing the increase in overall device complexity.
Solution Approach 2:
The blocking element is pre-positioned on the resilient latching elements in a delivery-ready state, with the predetermined breaking point already prepared for interruption during assembly. This preliminary arrangement ensures that the blocking function is built-in from the start, and when the breaking point is interrupted during installation, the blocking element automatically assumes its blocking position, providing enhanced security without requiring complex additional mechanisms.
3Adaptability or versatility
If the base body and blocking element are manufactured as separate components, then assembly flexibility is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The base body and blocking element are manufactured as separate components with a predetermined breaking point connection already prepared, allowing them to be easily assembled by simply interrupting the breaking point during installation. This preliminary preparation of the connection interface provides assembly flexibility while keeping the manufacturing process simple and cost-effective for each individual component.
Solution Approach 2:
The fastening element is segmented into a base body and a blocking element that can be manufactured separately using cost-effective processes and then easily assembled together. This segmentation allows each component to be optimized for its specific manufacturing requirements and assembled through a simple breaking point interruption, providing both manufacturing efficiency and assembly flexibility without increasing overall complexity.
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
Enables quick and secure assembly of door and window fittings by eliminating the need for screwing, ensuring reliable hold and easy retrofitting of standard faceplates with no risk of unintentional release.
Implementation Method 1
at least one resilient latching element arranged on the base body for gripping behind an attachment of the fitting groove
Implementation Method 2
a blocking element guided in or on the base body, which can be moved between a release position allowing movement of the latching element and a blocking position blocking movement of the latching element

AI summary
A fastening element for fastening a strike plate in a fitting groove of a window, door or the like comprises a base body, which is designed as a component separate from the strike plate, a coupling section that can be attached to the base body or formed integrally with it for the positionally fixed coupling of the base body with the strike plate and at least one spring-loaded locking element arranged on the base body for engaging behind a projection of the fitting groove.
