Door Hardware Illumination Device with Motion Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting solutions fail to provide effective, direct, and accessible illumination for door handles and locks in dark or dimly lit areas, leading to user anxiety and inconvenience, especially for children, and require manual activation which can be difficult in dark environments.
Innovation Solution
A 'smart' illuminating light device with a motion sensor, rechargeable battery, and timer circuit that automatically turns on when motion is detected, providing direct and indirect illumination to specific areas like door handles and locks, and can be easily attached to surfaces using adhesive or magnetic fasteners, allowing for wireless control via smartphone apps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lamps or nightlights are placed on tables or walls to provide light sources in rooms, then general illumination is provided, but the lighting is indirect and ineffective for seeing door handles and locks
Solution Approach 1:
The patent applies local quality by positioning the light source specifically adjacent to the door handle and lock area rather than providing general room illumination. The light device is configured to illuminate only the specific area where it is needed (the door hardware), making the lighting effective for its intended purpose while avoiding unnecessary general illumination.
2Illumination intensity
If a light source is attached to a wall opposite from the door to provide direct lighting, then illumination is provided, but the light source is blocked by the individual standing in front of the door creating shadows
Solution Approach 1:
The patent uses the door itself as an intermediary surface to mount the light source. By attaching the light device to the door or door frame rather than the wall opposite the door, the light is positioned to illuminate the door handle area from an angle that prevents shadow creation by the user's body.
3Loss of energy
If conventional lights require manual turning on using light switches or outlets, then energy is saved when not in use, but it is difficult to locate and activate lights in dark environments
Solution Approach 1:
The patent implements self-service by incorporating a motion sensor that automatically detects when someone approaches the door and activates the light accordingly. The system serves itself by sensing the need for illumination and activating without requiring manual intervention, eliminating the problem of not being able to locate switches in dark environments while maintaining energy efficiency through automatic deactivation when motion is no longer detected.
4Illumination intensity
If light sources provide broad illumination in dark areas, then general visibility is improved, but the specific area of door handles and locks remains difficult to see
Solution Approach 1:
The patent applies local quality by designing the light device with a specific orientation and positioning that directs illumination precisely at the door handle and lock area. The device is configured to provide targeted lighting rather than broad ambient light, ensuring that the specific area requiring interaction is clearly visible.
