Electronic Deadbolt Lock Braking Mechanism for Tolerance Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic deadbolt locks fail when there is a small tolerance between the deadbolt and the hole on the wall, as they are not designed to be manually aligned or inserted, and repeated attempts can lead to mechanical failure.
Innovation Solution
An electronic deadbolt lock with a braking mechanism controlled by an electronic recognition device, allowing the turnpiece to be rotated only after user verification, enabling precise alignment and insertion of the deadbolt, while also incorporating a key operating mechanism for manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an electronic deadbolt lock is designed to automatically insert the deadbolt into the hole on the wall, then the locking operation is faster and more convenient, but the deadbolt cannot be precisely inserted when there is a small tolerance between the deadbolt and the hole
Solution Approach 1:
The turnpiece is designed to be rotatable only after electronic verification, transitioning from a static locked state to a dynamic operational state. This allows the system to adapt between automatic operation (when verified) and manual alignment capability (when verification fails or is bypassed), resolving the contradiction between speed and precision.
Solution Approach 2:
The braking mechanism changes the rotational parameter of the turnpiece from restricted (braked) to free (unbraked) based on verification status. This parameter change enables the deadbolt to be precisely aligned and inserted when tolerance issues arise, while maintaining fast automatic operation under normal conditions.
2Ease of operation
If an electronic deadbolt lock is designed to automatically insert the deadbolt, then the operation is easier, but repeated attempts can lead to mechanical failure
Solution Approach 1:
The braking mechanism applies a preliminary restraining force to the turnpiece, preventing unauthorized or repeated failed insertion attempts. This anti-action protects the mechanical components from damage caused by forced or repeated unsuccessful operations, while still allowing easy operation after successful verification.
3Reliability
If a braking mechanism is added to control turnpiece rotation, then security and insertion precision are improved, but the device complexity increases
Solution Approach 1:
The braking mechanism uses a gear-driven stopping member controlled by an electronic recognition device, replacing purely mechanical key-based systems. This substitution integrates electronic control with mechanical braking, providing enhanced security and precision while managing complexity through electromechanical integration rather than purely mechanical solutions.

AI summary
An electronic deadbolt lock which includes a housing; an electronic recognition device disposed on the housing; a turnpiece pivotally mounted on the housing and connected to a deadbolt; a key operating mechanism disposed on the housing and connected to the deadbolt, wherein the deadbolt moves as a result of rotation of one of the turnpiece and the key operating mechanism; and a braking mechanism controlled by the electronic recognition device, wherein the braking mechanism normally applies a brake to the turnpiece to prevent the turnpiece from being rotated, and it is only when a user passes verification by the electronic recognition device that the turnpiece can be rotated by the user.
