Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If light emitting units are arranged in a conventional horizontal position, then the structure is simple and easy to manufacture, but dead zones are generated due to limited beam angle
Solution Approach 1:
The patent transitions from horizontal mounting to inclined mounting of light emitting units on a conical support surface. This dimensional change in mounting orientation allows the light beams to diverge at wider angles, eliminating dead zones while maintaining manufacturing simplicity through the conical geometry.
Solution Approach 2:
The conical (curved) support surface replaces flat horizontal mounting surfaces. This curvature enables uniform inclined positioning of multiple light emitting units, optimizing beam angle distribution and eliminating dead zones through geometric arrangement.
2Illumination intensity
If the beam angle is increased by changing light emitting unit orientation, then dead zones are reduced, but the device complexity increases
Solution Approach 1:
The conical support surface simultaneously serves multiple functions: it provides mechanical support for light emitting units, establishes inclined positioning for optimal beam angle, and creates uniform spatial distribution. This multi-functionality achieves wide beam angle without proportionally increasing complexity.
Solution Approach 2:
The conical geometry provides a simple yet effective curved surface that naturally establishes inclined orientations for multiple light emitting units, achieving wide beam angle coverage without complex adjustment mechanisms or multiple separate components.
3Illumination intensity
If more light emitting units are used to eliminate dead zones, then light emission quality improves, but material cost increases
Solution Approach 1:
By mounting light emitting units on an inclined conical surface rather than horizontally, each unit's light beam covers a wider angular range. This dimensional change in mounting orientation increases the effective coverage area per unit, reducing the total number of units needed to eliminate dead zones.
