Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting systems use light emitting elements with variable emission properties, then dynamic adjustment of light properties is achieved, but manufacturing cost increases significantly
Solution Approach 1:
The lighting system divides the light emitting elements into multiple sets with fixed emission properties (e.g., first set for warm white, second set for cool white). The processor selectively activates different sets to achieve dynamic light property adjustment without requiring each element to be individually variable, thus reducing manufacturing cost while maintaining adaptability.
Solution Approach 2:
The patent combines multiple sets of light emitting elements with fixed properties into a single integrated lighting system. By merging these fixed-property sets under unified processor control, the system achieves variable emission characteristics comparable to expensive variable-property elements, resolving the contradiction between adaptability and manufacturing cost.
2Adaptability or versatility
If lighting systems incorporate electromagnetic signals outside the visible spectrum, then advanced imaging and communication capabilities are enabled, but device complexity increases
Solution Approach 1:
The lighting system is designed to perform multiple functions using the same hardware infrastructure. The light emitting elements serve both traditional illumination purposes and advanced functions such as imaging (using invisible spectrum signals) and communication (via modulated light signals). This multi-functionality approach enables expanded capabilities without proportionally increasing device complexity.
Solution Approach 2:
The processor acts as an intermediary that manages the complexity of coordinating multiple light emitting element sets for diverse functions. It selectively controls which sets are activated based on the required function (illumination, imaging, or communication), thereby enabling versatile capabilities while maintaining manageable system complexity through centralized intelligent control.

AI summary
A connected lighting system that includes a substrate defining a broad face, a first set of light emitting elements, and a second set of light emitting elements. Each light emitting element of the second set of light elements may be configured to emit light having a fixed color parameter different from a first color parameter of the first set of lighting elements. The first and second sets of light emitting elements may be arranged at at least two different contiguous portions of the broad face of the substrate. A processor may be configured to control the first set of light emitting elements with a predetermined intensity and control relative intensities of one or more of the second set of light emitting elements to cooperatively emit light having a first color parameter value.
