Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic locks are inaccessible when both the sensing card and key are unavailable.
Innovation Solution
An electronic lock system that allows access using a sensing card, mobile device, or by manually turning a rotary seat, incorporating a lock core unit, driving unit, control module, position-sensing unit, and indication unit to enable operation without the need for both sensing card and key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic lock requires both sensing card and key for access, then security is improved, but accessibility and ease of operation deteriorate when both items are unavailable
Solution Approach 1:
The patent changes the access method parameters by introducing multiple alternative access modes (sensing card, key, and rotary seat combinations) instead of requiring a single fixed method. This allows the system to adapt to different situations while maintaining security through multi-factor verification.
Solution Approach 2:
The rotary seat is designed to serve multiple functions: it can be used alone in combination with sensing card detection, or in combination with key insertion, or as a mechanical backup. This multi-functionality ensures the lock remains accessible through various pathways while maintaining security requirements.
2Ease of operation
If multiple access methods are provided, then accessibility is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple access methods into a unified control system where the control module coordinates sensing card detection, key insertion detection, and rotary seat position monitoring. This integration allows complex functionality to be managed through a centralized control architecture rather than separate independent systems.
Solution Approach 2:
The access control functionality is segmented into distinct modules: sensing card detection module, key insertion detection module, rotary seat position detection module, and control module. Each module handles a specific aspect of access control, making the overall system more manageable and easier to implement despite the multiple access methods.
3Adaptability or versatility
If rotary seat with multiple positions is added, then alternative access method is provided, but manufacturing complexity increases
Solution Approach 1:
The rotary seat is designed as a dynamic component with multiple rotatable positions rather than a static structure. This allows the same physical component to provide different access configurations based on its position, reducing the need for multiple separate mechanical structures and simplifying manufacturing.

AI summary
A electronic lock includes a locking block (22), a latch member (31), a rotary seat (4), a control module (5) mounted to the rotary seat (4), and a position-sensing unit (6) mounted to the rotary seat (4), and output signals upon rotation of the rotary seat (4). The control module (5) is configured to receive the output from the position-sensing unit (6) to thereby compose a string, and then compares the composed string with a built-in string. When the composed string matches the built-in string, the control module (5) sending an engaging command for moving the latch member (31) to engage the locking block (22).
