Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metallic joinery locks face challenges in accommodating anti-panic mechanisms and adaptable functionality due to space constraints, leading to limited actuation options and safety features, with existing designs often being non-interchangeable and lacking smooth operation.
Innovation Solution
A multi-purpose casing with a specific design featuring a body, lateral cover, and front, incorporating reciprocal bearings and toothed rotary levers, a radial extension with a vertical arm and spring mechanism, and discoid flange rollers for smooth operation, allowing for anti-panic and reversible actuation, and compatibility with both right-hand and left-hand doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lock mechanism is designed with anti-panic features and multiple actuation options, then the safety and versatility of the lock is improved, but the device complexity and space requirements increase
Solution Approach 1:
The lock mechanism is designed with a universal casing that can accommodate multiple actuation mechanisms including traditional key actuation, anti-panic actuation, and reversible actuation for left-hand and right-hand doors. The single casing integrates multiple functional elements such as the follower, follower supplement, toothed rotary levers, and articulated latch, allowing one device to serve multiple security and operational purposes without requiring separate locks for different door configurations
Solution Approach 2:
The invention merges previously separate lock mechanisms into a single integrated assembly. The follower (4) and follower supplement (4a) are combined within the same casing, along with the first and second toothed rotary levers (10, 11) and the articulated latch (7). This consolidation reduces the number of separate components and simplifies installation while maintaining multiple actuation options and safety features
2Adaptability or versatility
If the lock mechanism is designed with multiple bearings and rotary levers for reversible actuation, then the adaptability for left-hand and right-hand doors is improved, but the device complexity increases
Solution Approach 1:
The lock mechanism employs asymmetric design elements that enable reversible actuation for both left-hand and right-hand doors. The first and second toothed rotary levers (10, 11) with their specific bearing arrangements (1e, 1f, 1g and 2a, 2b, 2c) create an asymmetric mechanism that can be configured for different door orientations. This asymmetric design allows the same casing to adapt to different installation scenarios without requiring mirror-image versions
3Ease of operation
If the horizontal groove is made longer and wider to accommodate the articulated latch, then the ease of operation is improved, but the volume of the casing increases
Solution Approach 1:
The horizontal groove (1k) in the lateral wall is designed with locally enhanced dimensions - longer and wider than the groove in the cover - specifically at the regions where smooth operation is needed for the articulated latch (7) and button (7h). This localized dimensioning provides the necessary clearance for smooth latch operation without increasing the overall casing volume uniformly, maintaining compactness while ensuring operational ease at critical locations
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
The solution enables reliable, smooth, and silent operation of the lock mechanism with enhanced safety features and adaptability, addressing the limitations of existing designs by providing a versatile and efficient locking system within constrained metallic sections.
Implementation Method 1
a vertical spring is intercalated between the inferior protrusion of the vertical arm and the supporting element of the articulated latch
Implementation Method 2
a vertical spring is intercalated between the inferior protrusion of the vertical arm and the supporting element of the articulated latch; the vertical arm has an elevated position corresponding to a compressed state of the vertical spring and that the superior protrusion remains outside of the free space
