Emergency Door Lock Secondary Seat Alarm Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency door-locking devices face challenges in efficiently integrating sensing and alarm components due to limited internal space in the main lock seat, leading to increased installation costs and complexity.
Innovation Solution
An automatic-alarming push-down type emergency door-locking device is designed with a position-sensing module and alarm module housed within the secondary lock seat, allowing for automatic sensing and alarming without altering the internal locking/unlocking mechanisms of the main lock seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing and alarm components are installed inside the main lock seat, then the alarm function can be integrated, but the limited internal space of the main lock seat makes installation difficult and increases complexity
Solution Approach 1:
The lock system is divided into two separate lock seats: the main lock seat for locking elements and the secondary lock seat for sensing and alarm components. This segmentation allows each component to be installed in its dedicated space, avoiding interference and simplifying installation while maintaining full functionality.
Solution Approach 2:
Instead of installing all components in the same spatial location (main lock seat), the solution moves the sensing and alarm components to a different spatial dimension (secondary lock seat), effectively utilizing unused space in the system architecture.
2Adaptability or versatility
If different sensing and alarm components are installed for different main lock seats, then each lock seat can have customized alarm functionality, but the preparation and installation costs increase
Solution Approach 1:
The secondary lock seat serves as a universal platform for housing sensing and alarm components that can support multiple lock seats. A single set of components in the secondary lock seat can provide alarm functionality for the entire locking system, eliminating the need for separate components for each main lock seat.
3Area of stationary object
If sensing and alarm components are installed outside the main lock seats, then space constraints are avoided, but strong protective shells are needed which increase preparation and installation costs
Solution Approach 1:
The sensing and alarm components are nested within the secondary lock seat structure, which is itself integrated into the existing lock system housing. This nested arrangement provides the necessary protection without requiring separate protective shells, as the lock seat structure itself serves as the protective enclosure.

AI summary
An automatic-alarming push-down type emergency door-locking device, disposed at a door board, includes a main lock seat, a secondary lock seat, a push-down type handle assembly, a position-sensing module and an alarm module. The main and secondary lock seats are disposed at the door board, and the main lock seat has at least one locking element. In the push-down type handle assembly, a first handle and a second handle are connected pivotally with the secondary and main lock seats to be moved along a driving path from a locking position toward an unlocking position. At the locking or unlocking position, the locking element is buckled with or separated from the at least one locking groove. The position-sensing module transmits an alarm-triggering signal for the alarm module to generate an alarm, upon when the first handle leaves the locking position.
