Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromechanical pivot lever latches face challenges in being ergonomically advantageous and universally usable, particularly due to increased failure susceptibility from additional movable components and non-standard mounting requirements, which compromise functional reliability and ergonomic design.
Innovation Solution
The electromechanical latch module features a latch housing that covers mounting openings, with a first locking device having a pivot lever handle and a second locking device activatable by an electric motor, where components are strategically positioned to allow universal mounting in various door configurations, eliminating the need for additional external covers and reducing mechanical components, thus enhancing reliability and ergonomics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If additional movable components (covers) are added to seal openings, then watertight sealing is improved, but device complexity and failure susceptibility increase
Solution Approach 1:
The invention extracts the sealing function from separate movable covers and integrates it into the latch housing structure itself. The housing is designed with sealed mounting openings that directly accommodate the locking mechanism, eliminating the need for additional sealing covers and reducing overall device complexity while maintaining watertight protection.
Solution Approach 2:
The invention merges the sealing function with the structural housing design. The mounting openings are integrated into the housing body with built-in sealing features, combining what were previously separate functions (housing + sealing covers) into a unified structure, thereby reducing the number of components and potential failure points.
2Object-affected harmful factors
If additional movable components (covers) are added to seal openings, then watertight sealing is improved, but reliability deteriorates
Solution Approach 1:
The invention removes the unreliable movable sealing covers from the design and extracts only the essential sealing function, implementing it through fixed, sealed mounting openings in the housing. This eliminates the mechanical wear and potential failure associated with movable covers while maintaining effective sealing.
3Extent of automation
If non-standard mounting openings are used to accommodate electric motor components, then electromechanical functionality is achieved, but adaptability deteriorates
Solution Approach 1:
The invention designs the latch housing with standardized mounting opening dimensions that can accommodate both manual and electromechanical locking mechanisms. The housing structure and internal spacing are configured to universally fit standard door preparations, allowing the same housing to work with different actuation methods without requiring custom modifications.
Solution Approach 2:
The invention resolves the space conflict for electric motor components by utilizing the depth dimension of the housing. The mounting openings are designed with sufficient depth to accommodate motor actuators while maintaining standard external dimensions, effectively using three-dimensional space planning to achieve compatibility with standard door configurations.
4Adaptability or versatility
If standard mounting opening dimensions are used, then adaptability is improved, but space for electric motor components deteriorates
Solution Approach 1:
The invention compensates for the limited space in standard mounting openings by optimizing the depth dimension. The housing is designed with sufficient internal depth to accommodate electric motor actuators while maintaining standard width and height dimensions, effectively using vertical space planning to resolve the volume constraint.
Solution Approach 2:
The invention nests the electric motor components within the existing housing structure. The motor and its actuating mechanisms are integrated into the housing's internal volume, with components arranged to fit within the standardized mounting opening dimensions, similar to nesting smaller elements within a container without increasing the container's external size.

AI summary
An electromechanical latch module for a door is provided. Here, all electric or electronic components are situated in an electronics installation space which is encapsulated in a dust-tight and watertight manner and is disposed in a latch housing on the external side of the door. The module is able to be mounted on doors having the two most common hole patterns, and also in combination with a bar lock. An additional external cover for the lock cylinder is not required.
