Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic security locks face issues with incomplete or failed bolt extraction due to irregular alignment or high friction, leading to suboptimal security conditions that users cannot easily identify or rectify.
Innovation Solution
An automatic security lock design featuring a box-like body with actuation lever systems, including an actuation rod and slider mechanism, allows for full bolt extraction and user verification through key rotation, ensuring correct alignment and maximum protrusion of bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic actuation mechanism is used for bolt extraction, then security is improved by forcing maximum extraction configuration, but reliability deteriorates due to incomplete extraction caused by irregular alignment or high friction
Solution Approach 1:
The patent implements a feedback mechanism by providing a visual indicator (the bit visible through the window) that allows the user to verify whether the bolt has been fully extracted. This feedback loop enables the user to identify incomplete extraction and take corrective action by rotating the key further, thereby resolving the contradiction between automatic actuation and user ability to identify/rectify malfunctions.
Solution Approach 2:
The system allows the user to self-diagnose and self-correct extraction issues by observing the bit position and rotating the key accordingly. The transparent window design enables the user to monitor the extraction process and perform necessary adjustments without requiring technical expertise or external assistance.
2Adaptability or versatility
If traditional lock appearance is maintained for easy replacement, then adaptability is improved, but device complexity increases due to integration of automatic actuation and verification mechanisms
Solution Approach 1:
The patent merges multiple functions into a unified mechanism: the key cylinder serves both as the traditional user interface and as the actuator for automatic bolt extraction. The bit and window are integrated into the existing lock body structure, combining verification functionality with the traditional lock appearance. This merging approach enables easy replacement while managing complexity through functional integration.
Solution Approach 2:
The key cylinder is designed to serve multiple functions: it acts as the traditional key interface, the actuator for automatic bolt extraction, and the mechanism that positions the bit for verification. This multi-functionality reduces the need for separate components, thereby managing complexity while maintaining adaptability for replacement.
3Reliability
If bolt extraction is fully automated upon wing closure, then security is improved by eliminating user dependency, but measurement precision deteriorates as user cannot verify bolt configuration
Solution Approach 1:
The transparent window and visible bit provide direct visual feedback to the user about the bolt extraction status. This feedback mechanism restores measurement precision by enabling the user to verify whether the bolt has been fully extracted, complementing the automatic actuation system and ensuring security confidence.
Solution Approach 2:
The bit acting as a visual indicator serves as an intermediary between the internal bolt extraction mechanism and the user's verification capability. It translates the internal mechanical state into visible information, allowing the user to accurately assess the security condition without directly observing the bolt itself.
