Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illuminated mirrors face challenges in achieving high brightness while maintaining an aesthetically pleasing design, as recessing the light source from the translucent portion reduces lighting efficiency and visibility of reflections.
Innovation Solution
The implementation of a reflective element secured to the rear surface of the mirror adjacent to the translucent portion, coupled with a flexible substrate and non-orthogonal housing transitions, allows light to be reflected and passed through the translucent portion without being absorbed, enhancing brightness and hiding the light source from view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the light source is recessed from the translucent portion to maintain an aesthetically pleasing design, then the aesthetic appearance is improved, but the lighting efficiency and brightness are reduced
Solution Approach 1:
A reflective element is introduced as an intermediary component between the recessed light source and the translucent portion. This reflective element redirects light that would otherwise be absorbed by the housing or mirror back through the translucent portion, thereby maintaining brightness while preserving the recessed aesthetic design.
Solution Approach 2:
The housing surfaces that would normally absorb and waste light are converted into beneficial reflective surfaces. By applying reflective coatings or using reflective materials in the housing structure, the previously harmful light absorption is transformed into useful light redirection, improving overall lighting efficiency without changing the recessed design.
2Shape
If the light source is positioned behind the rear surface to hide it from view, then the aesthetic appearance is improved, but the light intensity and visibility are reduced
Solution Approach 1:
The reflective element serves as a mediator that bridges the gap between the hidden light source and the translucent portion. It captures light emitted backward or sideways from the recessed source and redirects it forward through the translucent portion, ensuring the light source remains hidden while maintaining full visibility and intensity of the illumination.
Solution Approach 2:
The solution moves the light redirection problem from a linear path into a multi-dimensional spatial arrangement. By positioning reflective elements on multiple housing surfaces at different angles, light is redirected from various dimensional paths all converging toward the translucent portion, maximizing illumination while maintaining the recessed design.
3Ease of manufacture
If conventional housing designs are used with orthogonal transitions, then manufacturing is simplified, but light absorption increases and brightness is reduced
Solution Approach 1:
The housing design parameters are modified by changing the transition angles from orthogonal to non-orthogonal configurations. These angular parameter changes optimize the reflective paths of light, reducing absorption and improving brightness. The manufacturing complexity increase is minimal and can be achieved through standard fabrication techniques with adjusted angles.
