Solution Overview

Problem

Existing dual lock systems for doors are cumbersome to use and install, particularly when retrofitting existing mortise lock casings, and often require multiple keys for authorized and unauthorized access, leading to management issues with extra keys.

Innovation Solution

A dual lock adapter module with a robust and space-efficient lock transfer mechanism, allowing for easy mounting of both mechanical and electromechanical lock cylinders of various sizes, using a module housing with cogwheel-based transfer members and adaptable mounting adapters, ensuring reliable operation and compatibility with existing lock systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a dual lock system with two lock cylinders is mounted outside the door to allow access for authorized persons, then access control is improved, but device complexity increases and key management becomes cumbersome

Engineering Contradiction:
Improveaccess controlVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dual lock system is divided into two independent lock cylinders mounted side-by-side on a common housing, each cylinder handling one access function. This segmentation allows independent operation of each lock while maintaining a unified structure, reducing overall system complexity compared to integrated designs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The common housing and mounting structure serve multiple functions: providing structural support for both cylinders, enabling unified installation on the door, and facilitating coordinated operation of both locks. This multi-functionality reduces the number of separate components needed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If existing mortise lock casings are retrofitted with dual lock systems, then access management is improved, but ease of manufacture and installation deteriorates due to compatibility issues

Engineering Contradiction:
Improveaccess managementVSAvoidease of installation
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The common housing is designed with universal mounting features that can interface with various existing door and lock configurations. The housing incorporates standardized mounting points and attachment mechanisms that work with different mortise lock casings, enabling retrofittable installation without custom fabrication for each existing lock type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If lock cylinders of various sizes are mounted within the housing, then adaptability is improved, but device complexity increases due to mounting adapters

Engineering Contradiction:
Improvelock cylinder compatibilityVSAvoidmounting adapter requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing incorporates localized adapter interfaces at specific mounting positions, allowing different sized lock cylinders to be accommodated at different locations. Each mounting position can be configured with appropriate local adapters while the overall housing structure remains standardized, minimizing the complexity increase from supporting multiple cylinder sizes.

Inventive Principle:
Principle #3Local quality

AI summary

A dual lock adapter module (2) configured to be mounted at a door, the adapter module (2) comprises a module housing (4) provided with at least two openings, a first opening (12), and a second opening (14), the first opening (12) leads to a first lock cylinder cavity (16), and the second opening (14) leads to a second lock cylinder cavity (18), within the module housing (4). wherein the first lock cylinder cavity (16) is configured to receive a first lock cylinder (20), and the second lock cylinder cavity (18) is configured to receive a second lock cylinder (22). The adapter module (2) also comprises a lock transfer mechanism (24) arranged within a mechanism cavity (25) in the module housing (4), and that said lock transfer mechanism (24) comprises a lock operating member (26) configured to operate a lock mechanism in the door when the adapter module (2) is mounted at a door, to set the lock mechanism in a locked state and in an unlocked state. The lock transfer mechanism (24) further comprises a first transfer member (28) and a second transfer member (30). A presumption to transfer a lock activity and an unlock activity by one of the first and second transfer members (28, 30) to the lock operating member (26), is that the other transfer member is in a neutral state. The lock operating member (26), the first and second transfer members (28, 30) comprise cogwheels arranged in a common plane, wherein the cogwheel of said lock operating member (26) is provided with cogs around its entire circumference, and the cogwheels of said first and second transfer members (28, 30) have a predetermined length of their entire circumferences not provided with cogs.
