Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single point light source is used, then the device structure is simple, but shadows are eliminated and light coverage is improved
Solution Approach 1:
The lighting system is divided into multiple independent light sources arranged in an array configuration. Each light source can be individually positioned and oriented, allowing the system to illuminate areas from multiple angles simultaneously, thereby eliminating shadows that would be cast by a single point source.
Solution Approach 2:
The patent transitions from a single-point (0D) or linear (1D) light source to a two-dimensional array of light sources. This dimensional expansion allows light to be emitted from multiple positions across a surface area, providing omnidirectional illumination that covers shadows and dark areas that would exist with traditional single-point sources.
2Illumination intensity
If traditional lighting styles (flood lights, throw lights, lanterns) are used, then each has specific lighting capabilities, but they require frequent positioning and aiming adjustments
Solution Approach 1:
The lighting array is designed to perform multiple lighting functions simultaneously - flood lighting, spot lighting, and ambient illumination - all from a single deployed structure. The array can be configured to illuminate different areas and angles without requiring repositioning, as the multiple light sources work together to provide comprehensive coverage.
Solution Approach 2:
The lighting array is pre-configured with multiple light sources positioned at different angles and orientations before deployment. This preliminary arrangement ensures that when the system is activated, it immediately provides multi-directional illumination without requiring the user to perform aiming or positioning adjustments during operation.
3Volume of moving object
If cylindrical throw lights are used, then the device is compact, but it is difficult to position and aim and can tip and roll
Solution Approach 1:
The compact cylindrical form factor is maintained by segmenting the light source into an array of multiple small LED elements arranged on the cylindrical surface. This segmentation allows each LED to be positioned at specific angles while maintaining the overall compact cylindrical structure, eliminating the need for large bulky housings.
Solution Approach 2:
The patent distributes light sources across the two-dimensional surface of the cylinder rather than using a single central point. This allows the compact cylindrical device to emit light in multiple directions simultaneously, providing aiming capability without requiring mechanical adjustment mechanisms that would increase size or complexity.
4Area of stationary object
If flood lights are used, then light coverage is provided, but the device is bulky and not suitable for tight spaces
Solution Approach 1:
The flood lighting function is achieved by segmenting the illumination task across multiple small LED sources arranged in an array on the cylindrical surface. Each LED contributes to the overall flood coverage, allowing the system to provide wide-area illumination from a compact form factor that can fit in tight spaces.
Solution Approach 2:
The patent combines multiple light sources, power supply components, control electronics, and mounting mechanisms into a single integrated cylindrical unit. This merging of functions allows the device to provide comprehensive flood lighting capabilities while maintaining a compact size suitable for tight spaces, eliminating the need for separate bulky components.
