Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser-based display systems face limitations in producing wide beams that can project long distances with minimal dispersion, particularly in entertainment settings, where they often suffer from blooming effects due to environmental factors like fog and smoke, and are restricted by the narrow beam width and single color output of individual lasers.
Innovation Solution
An array of red, green, and blue lasers is mounted coaxially in a base unit, allowing for focused and aligned beams to create a wide, long-distance projection with minimal dispersion, capable of producing over 16 million colors by varying intensity, and can be mounted on a gimbal for directional control or integrated into a display and control system for dynamic color and intensity modulation.

Engineering Contradiction Analysis
1Area of moving object
If a single laser is used to project beams, then the beam width is narrow and color is limited to one wavelength, but the device complexity is low
Solution Approach 1:
The patent divides the laser system into multiple individual lasers (typically three: red, green, and blue) arranged in an array. Each laser operates independently to produce its own beam, which are then combined to create a wider composite beam with multiple colors. This segmentation allows the system to achieve wide beam width and full-color capability while maintaining manageable complexity through modular design.
Solution Approach 2:
The patent merges multiple separate laser beams into a single composite beam through precise optical alignment and combining optics. The individual beams from red, green, and blue lasers are spatially overlapped and combined to create a unified wide beam that displays full-color capabilities, effectively merging multiple light sources into one coherent output.
2Reliability
If traditional lasers are used in fog or smoke environments, then blooming effects occur and beam focus is lost, but the setup is simple
Solution Approach 1:
The patent implements individual focusing optics for each laser in the array, allowing each beam to be independently focused to a specific distance. This local quality control ensures that each laser maintains its focus stability independently, preventing the blooming effect that occurs when traditional single lasers are used in fog or smoke environments.
Solution Approach 2:
The system allows dynamic adjustment of focus distance and beam parameters for each individual laser. By changing the focus parameter independently for each laser in the array, the system can optimize beam performance for different environmental conditions and distances, maintaining reliability without blooming effects.
3Adaptability or versatility
If individual lasers are used, then each laser is limited to single color output, but the device complexity is low
Solution Approach 1:
The patent segments the color output capability by using three distinct lasers (red, green, and blue) in an array. Each laser is responsible for producing one primary color, and by combining these segmented color sources, the system achieves full-color versatility (over 16 million colors) while keeping each individual laser component relatively simple.
Solution Approach 2:
The laser array system achieves multi-functionality by combining multiple single-color lasers into a unified system that can produce any color in the visible spectrum. The same hardware platform can dynamically switch between and combine different colors, making the system universally capable of full-color display applications.
4Length of stationary object
If laser beams are projected long distances, then dispersion occurs and beam quality degrades, but the setup is straightforward
Solution Approach 1:
The patent applies individual focusing optics to each laser in the array, enabling each beam to be precisely focused for long-distance projection. This local quality control ensures that each laser maintains optimal beam quality over extended distances, preventing dispersion and maintaining beam integrity throughout the projection path.
Solution Approach 2:
The system enables adjustment of focus and beam parameters for each individual laser to optimize performance for long-distance projection. By changing these parameters independently for each laser, the system can compensate for dispersion effects and maintain high beam quality over extended projection distances.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves low dispersion and long-distance projection of wide beams, enabling vibrant color displays and dynamic control, overcoming traditional limitations of narrow beam width and single color output, while allowing for safe and flexible directional adjustments.
Implementation Method 1
Laser is short for Light Amplification by Stimulated Emission of Radiation. The concept of a laser dates back to the late 1800s. In the early 1900s, Einstein proffered the theoretical physics behind the operation of a laser.
Implementation Method 2
Laser may also be used to create 'atmospheric' or beam effects, in which an audience sees the laser beam as it moves through the air. This effect is due to Rayleigh scattering, which is the scattering of light, or other electromagnetic radiation, off small molecules in the air.
