Rotating Receiving Housing for Secure Door Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door closing aids face challenges in efficiently transferring force to the door leaf, especially near the closed position, and require separate components on the door frame and leaf, complicating installation and design integration.
Innovation Solution
A closing aid comprising a base body, receiving housing, and gear, where the receiving housing is rotatable or linearly movable via a drive, interacting with a door opener or screw-on piece to ensure secure closure without additional elements on the door leaf, using a self-locking gear mechanism to maintain the closed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate closing aid components are arranged on the door frame and door leaf, then the door can be securely closed in final angular positions, but the installation complexity increases due to additional openings and wiring requirements
Solution Approach 1:
The patent combines the closing aid components into a single integrated unit mounted on the door frame, eliminating the need for separate components on both the door frame and door leaf. This integration reduces installation complexity while maintaining the secure closing function through the receiving housing that accommodates the door opener or screw-on piece.
Solution Approach 2:
The receiving housing serves multiple functions: it accommodates either a door opener or a screw-on piece, providing universal compatibility with different locking mechanisms. This multi-functionality allows the same base structure to work with various door closure systems without requiring separate specialized components.
2Force
If a hydraulic or electric door closer is used to transfer additional force to the door leaf, then the door can be brought into the closed position, but the force transfer is insufficient shortly before the closed position due to changing lever arm
Solution Approach 1:
The receiving housing is designed to rotate about a rotation axis during the closing process, dynamically adjusting its position to maintain an optimal lever arm throughout the door's closing movement. This rotational movement ensures that force is effectively transferred even in the final positions where traditional fixed mechanisms fail.
Solution Approach 2:
The receiving housing acts as an intermediary mechanism between the door opener/screw-on piece and the door leaf. It translates the rotational or linear movement into effective force application on the door, bridging the gap between the locking mechanism and the door leaf to ensure reliable closing.
3Ease of operation
If the receiving housing is rotated about a rotation axis or moved linearly by the drive, then the door can be pulled into the closed position, but the mechanism complexity increases
Solution Approach 1:
The closing mechanism is segmented into distinct functional components: the base body for mounting, the receiving housing for accommodating the door opener, and the drive mechanism for movement. This segmentation allows each component to be optimized independently while maintaining overall simplicity and ease of operation.
