Modular Lock Chassis With Movable Control Module for Battery Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks with integrated energy sources, such as batteries, require laborious demounting procedures for access and replacement due to their compact design, which complicates installation and maintenance.
Innovation Solution
A modular lock design with a separable control module and chassis, allowing access to the energy source without demounting, featuring a movable control module that slides relative to the chassis, enabling easy battery replacement or recharging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the lock is designed with a compact construction and actuating elements arranged at an accessible external side, then the lock achieves a space-saving and user-friendly design, but access to the energy source becomes difficult requiring demounting of the lock
Solution Approach 1:
The lock is divided into a fixed part (chassis with locking means and energy source receptacle) and a movable part (control module with control means). This segmentation allows the control module to be removed independently, providing access to the energy source without demounting the entire lock from the door.
Solution Approach 2:
The control module is designed to be movable relative to the chassis, transitioning between a fixed operational position and a removed position. This dynamic design enables easy access to the energy source by simply detaching the control module, eliminating the need to remove the entire lock assembly.
2Stability of the object's composition
If the energy source is installed in a compartment accessible at a face remote from the actuating elements, then the lock achieves a balanced component distribution, but access to the energy source requires laborious demounting of the lock
Solution Approach 1:
The lock components are segmented into a fixed chassis containing the energy source receptacle and a separable control module. This allows the control module to be removed independently for energy source replacement, making maintenance simple while keeping the overall component distribution balanced.
Solution Approach 2:
The design enables users to easily replace or recharge the energy source themselves by simply removing the control module and accessing the receptacle on the chassis, without requiring professional intervention or complex disassembly procedures.
3Adaptability or versatility
If the lock has components on both sides of a door with a connecting shaft passing through, then the lock achieves symmetrical functionality, but access to the energy source becomes more complicated
Solution Approach 1:
The lock is segmented into a removable control module and a fixed chassis that remains mounted on the door. This segmentation simplifies access to the energy source by allowing the control module to be detached from either side of the door, maintaining bidirectional functionality while reducing access complexity.

AI summary
A surface-mounted keylessly operated lock (10) comprises a chassis (11) mountable on one of two parts, especially a door and a door surround, to be locked and unlocked relative to one another and carrying locking means (17 to 23) transferrable between a locking state and an unlocking state respectively for the locking and unlocking, the locking means being electrically operable to cause or allow transfer from the locking state to the unlocking state. In addition, the lock includes a control module (16) mounted on the chassis (11) and carrying control means (30) for controlling supply of electrical operating power to the locking means. The chassis has a receptacle (25) for reception of an electrical energy source, especially batteries, for providing the operating power and the module (16) inclusive of the control means (20) is movable relative to the chassis (11) to permit access to the receptacle (25) to enable battery exchange without demounting of the installed lock.
