Swing Handle Arrangement with Dual Locking Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lift handle arrangements face challenges in compactly integrating two sturdy locking mechanisms within limited space to securely lock and unlock doors, while efficiently utilizing the available space within the handle housing.
Innovation Solution
A handle arrangement with a compact design that incorporates a single actuating device to control both locking mechanisms, allowing for efficient use of space and enhanced security, featuring a handle that moves between secured and released positions, and a second mechanism to prevent latch movement, ensuring secure engagement with the door frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate locking mechanisms are integrated into the handle housing, then security and locking reliability are improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines two separate locking mechanisms (first locking mechanism for securing handle to housing, second locking mechanism for preventing latch movement) into a single integrated handle arrangement. Both locking mechanisms share common components including a single actuating device (70) that can actuate both mechanisms, and are housed within the same handle housing (10), thereby achieving improved security while managing device complexity through integrated design
Solution Approach 2:
The actuating device (70) is designed with multi-functionality to control both the first locking mechanism (60) and the second locking mechanism (80) using a single actuation action. This universal actuating mechanism reduces the number of separate control devices needed and simplifies the overall system while maintaining dual locking functionality
2Reliability
If two separate locking mechanisms are integrated into the handle housing, then security and locking reliability are improved, but the space utilization within the handle housing becomes more difficult
Solution Approach 1:
The patent employs a nested arrangement where the first locking mechanism (60) and second locking mechanism (80) are integrated within the same handle housing (10) space. The mechanisms share common structural elements and actuating components, effectively nesting multiple locking functions within a compact volume. The actuating device (70) serves both mechanisms simultaneously, maximizing space utilization while maintaining both locking functions
Solution Approach 2:
By merging the two locking mechanisms into a shared housing space with common actuating components, the patent achieves compact integration. The first locking mechanism (60) with handle latch (61) and the second locking mechanism (80) with latch receiving element (21) are positioned to share structural support and actuation pathways, reducing the total volume required compared to separate housings

AI summary
Handle arrangement for arrangement to a door provided with a door latch, the handle arrangement comprising a housing having a hollow interior, and handle moveable relative to the housing along a first direction, the handle configured to couple to the door latch, wherein a movement of the handle along said first direction moves the door latch to or from the latching position; wherein the handle is moveable relative the housing along a second direction, between a secured position, in which position the handle is locked to the housing, and a released position, in which position the handle is moveable relative the housing about the first direction; a first locking mechanism configured to, in a locking state, lock the handle in the secured position, and in a releasing state, allow the handle to be moved to the released position, and a second locking mechanism.
