Cylinder Lock Illumination for Magnet Key Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cylinder lock devices are inconvenient to operate in the dark since the peripheral edge of the second opening, which faces the magnet lock's fitting recess, is not illuminated, making it difficult to manually unlock the magnet lock and insert the mechanical key.
Innovation Solution
Incorporating a dual illumination system with a single light guide member that illuminates the peripheral edges of both the first opening for mechanical key insertion and the second opening for the magnet lock, allowing remote switching of the light sources to facilitate easier operation in dark environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light guide member is used to illuminate both openings, then the number of components is reduced, but the illumination intensity at each opening may be insufficient
Solution Approach 1:
The single light guide member is divided into two separate light guide portions (first light guide portion and second light guide portion), each responsible for illuminating a specific opening. This segmentation allows each portion to be optimized for its specific illumination task while maintaining the overall benefit of using a single integrated light source structure.
2Ease of operation
If the light source is activated continuously, then the openings are always illuminated for operation, but energy consumption increases
Solution Approach 1:
The light source operates periodically rather than continuously, being activated only when needed for key insertion operations. The control unit receives signals from the operation signal receiving portion to trigger illumination, ensuring energy is consumed only during actual use rather than continuously.
Solution Approach 2:
The system incorporates a control unit that receives operational signals and activates the light source accordingly. This feedback mechanism ensures the illumination is provided precisely when operation is required, optimizing the balance between ease of operation and energy consumption.

AI summary
A cylinder lock is provided in which a casing is connectedly provided on a cylinder body of the cylinder lock while having a cover plate on an end part on a side opposite to the cylinder body, a shutter plate is housed in the casing so as to be capable of opening and closing a first opening for mechanical key insertion provided in the cover plate, and a magnet lock that has a tubular fitting portion into which a magnet key can be fitted is provided on the casing so that an outer end of the tubular fitting portion faces a second opening provided in the cover plate, wherein illumination means (47) including a first illumination portion (50b) that can light a peripheral edge of the first opening (29) and a second illumination portion (50c) that can light a peripheral edge of the second opening (35) is provided on the casing (16). This makes unlocking of the magnet lock in a dark easy
