Mirror Lighting Control for Semantic Cues Without Image Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mirrors used during personal care activities face challenges in providing semantic information without interfering with the evenness of lighting, as conventional methods can cause shadowing or color casting, affecting the visibility of the user's image.
Innovation Solution
An apparatus with a display surface and a light emitting portion that uses sensors to measure the user's position, allowing the control unit to adjust the light's intensity, color, and emission angle to minimize shadowing and color casting effects, ensuring optimal lighting and information delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If light is used to convey semantic information to the user, then information delivery is improved, but shadowing and color casting effects worsen the presented image of the user
Solution Approach 1:
The patent applies dynamics by making the lighting system adjustable and controllable in real-time. The control unit dynamically adjusts the intensity, color temperature, and emission angle of the light emitting portion based on sensor data about user position and environmental conditions. This dynamic adaptation allows the system to optimize both information delivery and image quality during different usage scenarios.
Solution Approach 2:
The patent implements parameter changes by modifying multiple lighting parameters including intensity, color temperature, and emission angle. The control unit adjusts these parameters based on the measured position of the user relative to the light emitting portion. For example, when the user is detected to be in a position where shadowing would occur, the system changes the emission angle or intensity to minimize the harmful effects while maintaining semantic information delivery.
2Loss of information
If the light emitting portion is used to provide semantic information, then information presentation is improved, but evenness of lighting on the user deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the function of different parts of the lighting system. The light emitting portion is divided into multiple independent light emitting elements that can be controlled separately. This allows the system to provide semantic information through specific localized light patterns while other elements maintain even illumination on the user's face and body, thus resolving the contradiction between information presentation and lighting evenness.
Solution Approach 2:
The patent implements segmentation by dividing the light emitting portion into multiple independently controllable light emitting elements. This segmentation allows the control unit to selectively activate specific elements for conveying semantic information while keeping other elements active for providing even illumination. The sensor detects user position and the control unit adjusts which segments are used for information delivery versus illumination, maintaining both functions simultaneously.
3Loss of information
If an integrated display is used inside the mirror to present semantic information, then information delivery is improved, but the reflected image of the user is interfered with
Solution Approach 1:
The patent applies the extraction principle by removing the semantic information presentation function from the reflective surface itself. Instead of displaying information directly on the mirror surface (which would interfere with the reflected image), the system extracts this function and implements it through the light emitting portion. The light emits semantic information in a manner that does not obstruct or degrade the quality of the user's reflected image, thus resolving the contradiction between information delivery and image quality.
