Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light emitting device is positioned close to the extension portion to maximize light output, then luminance is improved, but light reflection occurs causing luminous efficiency to deteriorate
Solution Approach 1:
The light emitting device is extracted from direct contact with the extension portion and positioned at a predetermined interval away from it. This separation eliminates the harmful light reflection that would occur if the light emitting device were placed directly against the extension portion, while still maintaining sufficient luminance output through proper optical design of the light guide plate and diffusion plate.
Solution Approach 2:
A light guide plate is introduced as an intermediary component between the light emitting device and the extension portion. The light guide plate receives light from the LED, guides it through its internal structure, and distributes it evenly through a diffusion plate, preventing direct reflection from the extension portion while maintaining high luminous efficiency.
2Device complexity
If conventional lighting structures are used to maintain simple design, then device complexity is reduced, but adaptability to different spaces is limited
Solution Approach 1:
The lighting apparatus is divided into modular components: a base portion, an extension portion, a light source unit, a light guide plate, and a diffusion plate. This segmentation allows the extension portion to be adjusted or configured for different spatial requirements while maintaining a simple overall structure, thereby increasing adaptability to various installation environments.
Solution Approach 2:
The lighting apparatus incorporates an extension portion that extends in a direction substantially perpendicular to the base portion, utilizing vertical or lateral spatial dimension. This dimensional approach allows the lighting device to adapt to different ceiling heights, wall distances, and room configurations without complicating the fundamental structure.
