Keyless Lock Battery Access via Movable Control Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks with integrated energy sources, such as batteries, require laborious and complicated procedures for access and replacement due to their compact design, necessitating demounting of lock components.
Innovation Solution
A lock design that separates the chassis and a movable control module, allowing access to the energy source without demounting, by incorporating the control means into the module and enabling sliding or pivoting motion relative to the chassis, with secure electrical connections and a releasable securing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a lock body is divided into a head portion and a shank portion with a transverse fracture surface, then the lock can be broken open by applying force to snap the shank, but the lock may remain stuck in the closed position after breaking due to deformation of the lock body
Solution Approach 1:
The locking mechanism is extracted from the lock body by breaking the shank portion at the transverse fracture surface, separating the locking function from the body structure. This allows the lock to be broken open quickly while the hasp remains intact for removal.
Solution Approach 2:
The lock body is segmented into a head portion and a shank portion with a defined fracture surface, allowing the shank to break independently at a predetermined location without damaging the hasp or requiring removal of the entire lock assembly.
2Strength
If a padlock has a shackle that is rigid and resistant to cutting, then the padlock provides strong security, but the shackle cannot be opened by bending or snapping forces
Solution Approach 1:
The shackle transitions from a static rigid structure to a dynamic component with a predetermined fracture surface that allows controlled breaking. The shank portion is designed to fail in a specific manner under excessive force, providing both security during normal use and emergency release capability.
Solution Approach 2:
The transverse fracture surface is pre-formed in the shank portion during manufacturing, preparing the weak point in advance so that when breaking force is applied, the shank snaps cleanly at the predetermined location rather than requiring forceful breaking anywhere along the shackle.
3Device complexity
If the lock body is made as a single solid piece, then the lock structure is simple and strong, but the lock cannot be broken open quickly without damaging the hasp
Solution Approach 1:
The lock body is divided into distinct portions (head and shank) with a defined fracture surface between them, maintaining overall structural simplicity while enabling quick breaking at the predetermined location without damaging the hasp or requiring complex mechanisms.

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.
