Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic locks face issues with misalignment during installation, leading to increased motor load, reduced battery life, and potential failure in operation due to interference from door jambs and strike plates, especially when misalignment is not detected early.
Innovation Solution
An electronic lock with a misalignment scoring system that includes a misalignment detection unit and scoring unit, which measures physical characteristics like current, voltage, and torque to determine a lock misalignment score, providing direct feedback to users or installers to improve alignment and extend battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the lock is installed without misalignment detection, then installation is simple and quick, but misalignment causes increased motor load and reduced battery life
Solution Approach 1:
The misalignment detection system performs alignment verification during the installation phase before the lock enters normal operation. The detection unit measures the relationship between the lock body and door, and the scoring unit evaluates alignment quality, allowing installers to correct misalignment issues before they cause motor overload and battery depletion during actual use.
Solution Approach 2:
The system provides real-time feedback through a scoring mechanism that quantifies alignment quality. The detection unit continuously monitors bolt movement parameters, and the scoring unit translates these measurements into actionable alignment scores, enabling users to understand and correct misalignment issues to optimize battery life.
2Reliability
If misalignment is detected and corrected, then operational reliability improves, but installation complexity increases
Solution Approach 1:
The misalignment detection system is integrated into the lock itself, making the alignment verification capability inherent to the product rather than requiring external specialized tools or procedures. The detection unit and scoring unit work together to provide self-contained alignment assessment, reducing the need for additional installation equipment or expert intervention.
Solution Approach 2:
The system transforms the complex physical alignment problem into a simplified numerical scoring system. By measuring multiple alignment parameters and combining them into a single misalignment score, the system makes alignment assessment and optimization accessible to typical installers without requiring deep mechanical expertise.
3Reliability
If the motor operates under high load due to misalignment, then the lock can still function, but battery life is significantly reduced
Solution Approach 1:
The system detects and alerts users to misalignment conditions during installation or early use, before the cumulative effect of high motor load significantly depletes the battery. This preliminary detection allows corrective action to be taken while battery life is still adequate.
Solution Approach 2:
The continuous monitoring and scoring system provides feedback on alignment quality, enabling users to understand the relationship between misalignment and battery consumption. This feedback loop motivates users to correct alignment issues to optimize energy usage and extend battery life.

AI summary
An electronic lock with a lock assembly that includes a bolt movable between an extended position and a retracted position. The electronic lock includes a motor configured to drive the bolt between the extended position and the retracted position. A controller is provided that is configured to control actuation of the motor to selectively move the bolt between the extended position and the retracted position. The electronic lock includes a user interface configured to output information about the electronic lock. A misalignment scoring means is provided for detecting interference to movement of the bolt between the extended position and the retracted position and determining a lock misalignment score based on the detected interference. The user interface identifies the lock misalignment score.
