Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light is directed from the rear onto a transparent or translucent cover, then the cover emits light in one or more directions, but the light distribution is not selectively controllable in specific directions
Solution Approach 1:
The cover is divided into multiple areas (first area, second area, third area) with different light-deflecting structures, allowing each area to independently direct light in specific directions. This segmentation enables selective directional control of light emission from different regions of the cover.
Solution Approach 2:
Different areas of the cover are equipped with different light-deflecting structures tailored to their specific functional requirements. For example, the first area has structures for directing light in one direction while the second area has structures for different directional control, optimizing light distribution locally for each function.
2Adaptability or versatility
If multiple lighting elements are arranged in an interior space, then various lighting functions can be achieved, but the interior areas are not visually separated
Solution Approach 1:
A light barrier is introduced as an intermediary element between different interior areas to visually separate them. This light barrier allows the system to maintain multiple lighting functions while providing clear visual separation between different lighting zones, reducing structural complexity.
3Illumination intensity
If light-deflecting structures are added to the cover, then light can be directed in specific directions, but the manufacturing process becomes more complex
Solution Approach 1:
The light-deflecting structures are integrated directly into the cover manufacturing process, combining the cover and light-deflecting structures into a single component. This merging eliminates the need for separate assembly steps and reduces manufacturing complexity despite the added functional complexity.
Solution Approach 2:
The cover serves multiple functions: it acts as a protective enclosure, a light-emitting surface, and a light-directing element through its integrated light-deflecting structures. This multi-functionality reduces the need for additional components and simplifies the overall manufacturing process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
