Electronic Lock Bistable Display for On-Lock Error Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diagnosing errors in access control systems, particularly electronic locks, is cumbersome and requires additional steps such as connecting a handheld device for data retrieval and interpretation.
Innovation Solution
Incorporating a bistable display, such as an electrophoretic, bistable liquid crystal, or electrochromic display, into electronic locks to provide always-on lock status indicators and error codes, including QR codes for error handling, directly on the lock, eliminating the need for external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a handheld device is used to retrieve and interpret audit data from the electronic lock, then diagnostic capability is provided, but device complexity and operational steps increase
Solution Approach 1:
The patent merges the diagnostic functionality into the electronic lock itself by incorporating a display device that can show error codes and diagnostic information directly on the lock. This eliminates the need for separate handheld devices and reduces operational steps by combining the lock and diagnostic display into a single integrated system.
Solution Approach 2:
The electronic lock performs self-diagnosis by automatically detecting errors and displaying them on its integrated display device. The system serves itself by providing diagnostic capabilities without requiring external intervention or additional equipment, thereby reducing operational complexity.
2Difficulty of detecting and measuring
If a handheld device is used for error diagnosis, then diagnostic information can be retrieved, but time required for diagnosis increases
Solution Approach 1:
The electronic lock performs preliminary diagnostics automatically when errors occur, capturing and preparing diagnostic information before any user intervention is needed. The display device is pre-configured to immediately show error codes and diagnostic information, eliminating time delays associated with manual data retrieval and interpretation.
Solution Approach 2:
The system provides immediate feedback to users by displaying error codes and diagnostic information directly on the lock's display device. This real-time feedback mechanism eliminates the time required for manual data retrieval and interpretation, allowing users to immediately see and understand diagnostic results.
3Difficulty of detecting and measuring
If traditional diagnostic methods are used, then error information can be obtained, but ease of operation decreases
Solution Approach 1:
The electronic lock provides self-service diagnostic functionality by automatically detecting errors and displaying them on its integrated display device. Users simply need to view the display, eliminating the need for complex manual procedures or additional equipment, thereby significantly improving ease of operation.
Solution Approach 2:
The display device uses visual indicators including color changes to communicate error states and diagnostic information. This visual feedback mechanism makes error detection intuitive and easy to understand, improving ease of operation by presenting complex diagnostic data in simple, visually distinct formats.

AI summary
An electronic lock for leveraging always-on lock indicator display technologies according to an embodiment includes a bistable display, at least one processor, and at least one memory comprising a plurality of instructions that, in response to execution by the at least one processor, causes the electronic lock to perform a diagnostic on the electronic lock to determine a status of the electronic lock, determine whether an error has occurred on the electronic lock based on the determined status of the electronic lock, and modify a current display image of the bistable display to display an error code on the bistable display in response to a determination that the error has occurred on the electronic lock, wherein the error code is associated with the error that has occurred on the electronic lock.
