Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single top-end light source is used, then the structure is simple, but the lighting style is simple and cannot meet diverse usage requirements
Solution Approach 1:
The lighting fixture is divided into multiple independent light source modules: a first light source module with multiple columns of light-emitting elements arranged circumferentially on the side wall, and a second light source module at the top end. Each module can be independently controlled to produce different lighting effects, thereby achieving diverse lighting styles without requiring a completely complex restructuring of the overall device.
Solution Approach 2:
The first light source module transitions from traditional top-down illumination to circumferential lateral illumination along the side wall. The light-emitting elements are arranged in multiple columns around the circumference, emitting light in radial directions, which adds a new spatial dimension to the lighting pattern and creates complex lighting effects that were not achievable with single-directional top illumination.
2Illumination intensity
If multiple columns of light sources are arranged circumferentially, then light distribution is enhanced, but manufacturing complexity increases
Solution Approach 1:
The first light source module is segmented into multiple columns of light-emitting elements, where each column contains multiple light-emitting elements arranged along the height direction. This segmentation allows for modular assembly and facilitates uniform light distribution across the side wall while maintaining manageable manufacturing complexity through standardized column units.
Solution Approach 2:
Multiple columns of light-emitting elements are merged into a single integrated first light source module that is collectively mounted on the side wall. The face mask further merges and integrates the light output from all columns, combining their effects to achieve uniform side light emission while simplifying the overall assembly process through unified positioning and mounting structures.
3Adaptability or versatility
If light sources emit laterally toward the face mask, then lighting patterns are enhanced, but device complexity increases
Solution Approach 1:
The face mask serves multiple functions: it diffuses light from the circumferential light sources, shapes the light beam, and creates various lighting patterns. By making the face mask multi-functional, the patent achieves diverse light-emitting patterns without adding separate optical components, thereby enhancing versatility while controlling device complexity.
Solution Approach 2:
The face mask acts as an intermediary between the light-emitting elements and the external environment. It receives light from multiple columns of light sources and transforms it into a unified, diffused output with desired patterns. This intermediary component simplifies the optical system by consolidating multiple light paths into a single controlled output rather than requiring complex individual optical paths for each light source.
