Front-Access Door Frame Locking Device Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door frame systems and latching devices are cumbersome to assemble and retrofit, requiring access to the metal frame from behind, which is often inaccessible and involves significant effort, especially when installing new doors with mismatched latches or modifying frames deviating from standard dimensions.
Innovation Solution
The frame system and latching device design allow the latching device to be installed from the front, with a width in the Y-direction enabling easy insertion and adjustment, eliminating the need for rear access and allowing for effortless assembly and retrofitting without major structural changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the locking device is designed to be mounted from the rear of the metal frame, then the mounting structure can be securely attached, but the assembly process becomes complex and time-consuming requiring access to both sides of the frame
Solution Approach 1:
The locking device is inverted in its mounting approach: instead of requiring rear access to the metal frame for attachment, all mounting operations are performed from the front. The carrier is inserted through the locking opening from the front, and all fastening screws are accessible from the front side, eliminating the need for rear access while maintaining secure attachment.
Solution Approach 2:
The locking device is segmented into a carrier component and a locking element component that can be assembled separately. The carrier serves as the mounting interface that attaches to the metal frame from the front, while the locking element attaches to the carrier, allowing independent optimization of each component's mounting requirements.
2Ease of manufacture
If the locking device requires access to the rear of the metal frame for installation, then proper structural attachment can be achieved, but retrofitting existing frames becomes difficult and labor-intensive
Solution Approach 1:
The mounting approach is inverted to enable retrofitting: the carrier is designed to be inserted through the locking opening from the front and attached using screws accessible from the front. This allows the locking device to be installed on existing metal frames without requiring disassembly or access to the rear of the frame, significantly improving adaptability for retrofitting applications.
3Ease of manufacture
If the locking device is designed with standard dimensions, then manufacturing is simplified, but it cannot accommodate doors with mismatched latch positions or non-standard frame dimensions
Solution Approach 1:
The locking element is designed with adjustability along the carrier, allowing its position to be dynamically changed to match different latch positions on various doors. The locking element can be repositioned and fixed at multiple locations on the carrier, providing adaptability for doors with mismatched latch positions while maintaining a standardized carrier design for simple manufacturing.
Solution Approach 2:
The position parameter of the locking element along the carrier can be changed to accommodate different door configurations. By allowing the locking element to be adjusted to different positions on the carrier, the system can adapt to various latch positions and frame dimensions without requiring custom-manufactured components for each variation.
4Ease of operation
If the locking device width in Y-direction is reduced for easier insertion, then assembly is simplified, but the structural integrity and locking strength may be compromised
Solution Approach 1:
The locking device is segmented into a narrow carrier for easy insertion through the locking opening and a locking element that provides the actual locking function. The carrier can be made narrow in the Y-direction to facilitate easy insertion, while the locking element maintains sufficient width and structural features to ensure adequate locking strength and engagement with the door latch.
