Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light distribution element is used, then the structure is simple, but it is difficult to achieve precise light distribution in deep installation scenarios
Solution Approach 1:
The light distribution element is divided into multiple portions (first light distribution portion and second light distribution portion), each responsible for different angular ranges. This segmentation allows precise control of light distribution in each sector while maintaining overall structural feasibility in deep installation scenarios.
2Area of stationary object
If the installation depth is increased, then the light distribution coverage is improved, but the structural design becomes more difficult
Solution Approach 1:
By dividing the light distribution element into multiple portions, each handling specific angular ranges, the patent achieves comprehensive light distribution coverage in deep installations without requiring an overly complex single-structure design.
Solution Approach 2:
The light distribution element employs different structural configurations (such as prismatic surfaces, reflective surfaces, or micro-structured surfaces) in different spatial dimensions to control light propagation, enabling effective light distribution despite the deep installation constraint.
3Manufacturing precision
If multiple light distribution portions are used, then light distribution precision is improved, but the device complexity increases
Solution Approach 1:
Multiple light distribution portions are integrated into a single monolithic light distribution element that can be manufactured as one piece. This merging approach maintains precise light distribution control while simplifying manufacturing and reducing assembly complexity.
Solution Approach 2:
The light distribution element serves multiple functions simultaneously: it distributes light in different angular ranges, guides light from the light source, and can be integrated into various lamp configurations. This multi-functionality reduces the need for separate components.
4Manufacturing precision
If the light source installation depth is increased, then the light distribution pattern compliance is improved, but the design flexibility is reduced
Solution Approach 1:
The segmented light distribution element design allows adaptation to different lamp configurations and installation depths while maintaining statutory light distribution compliance. Each portion can be optimized for specific angular requirements.
Solution Approach 2:
The light distribution element utilizes variations in geometric parameters (such as prism angles, surface curvatures, or micro-structure dimensions) to control light distribution patterns, enabling compliance with statutory requirements across different installation scenarios.
