Modular Closure Device Interchangeable Insert Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular closure systems require multiple pivoted lever constructions and separate recesses or controls for different closure elements, increasing production costs and storage complexity.
Innovation Solution
A modular closure device with an interchangeable insert that can be adapted to various receptacles, featuring a lever hook mechanism that interacts with a guide to allow insertion from the front or rear, and is secured with a cap, utilizing a leg spring to automatically return the lever to its starting position without further actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pivoted lever constructions and separate recesses are provided for different closure elements, then each closure element can have its own dedicated control, but production costs and storage complexity increase
Solution Approach 1:
A single standardized pivoted lever construction is designed to work with multiple different closure elements (profile cylinders, profile half cylinders, finger levers) through a universal recess design. The lever body, shaft, and spring mechanism remain identical across applications, while only the closure element itself varies.
Solution Approach 2:
The closure system is segmented into modular components: a standardized lever assembly that remains constant, and interchangeable closure elements that can be independently replaced. This allows the lever construction to be separated from the specific closure element type, reducing the need for multiple complete lever assemblies.
2Ease of manufacture
If a standardized lever construction is used for different closure elements, then production costs and storage are reduced, but the mechanism must accommodate multiple closure element types
Solution Approach 1:
The recess and lever assembly are designed as universal components that can accommodate various closure element types (profile cylinders, profile half cylinders, finger levers) through standardized mounting interfaces and geometric compatibility, allowing a single lever construction to serve multiple functions across different door locking applications.
Solution Approach 2:
The lever is designed with dynamic characteristics (pivoting motion, spring-loaded return) that adapt to different closure elements while maintaining consistent operational behavior. The standardized spring mechanism and pivot point allow the lever to work with various closure element weights and geometries without requiring construction changes.
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 efficient adaptation to different closure systems by replacing only the interchangeable insert, reducing the need for multiple lever constructions and simplifying storage, while ensuring secure operation without additional user input.
Implementation Method 1
the lever hook is returned to the starting position by a leg spring, so that the lever is closed again without further actuation of the closure element

AI summary
A modular closure device for different closure elements, such as finger levers, plate cylinders, profile cylinders, profile half cylinders, for locking a pivot lever in a recess, is described, wherein the closure elements can be inserted and fastened in a receptacle arranged in the recess or the pivot lever, either from the front or from the rear, characterised in that the closure device, which has an interchangeable insert adapted to the closure device and having a different design for the various receptacles, interacts with a guide in such a way that this can be inserted into the recess or into the pivot lever, and the recess or the pivot lever having the inserted interchangeable insert can be plugged in a door leaf through an opening in the door leaf or the like and can be fastened with a cap.
