Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional accent lighting systems are used in smaller venues, then the lighting can be implemented with simple equipment, but the lighting effects are limited to dimmer capabilities and monochromatic options
Solution Approach 1:
The patent combines multiple lighting functions into a single device by integrating a coherent light source, holographic optical element, and switched-mode power supply into one retrofitable unit. This merging allows the device to provide both traditional dimming capabilities and advanced effects like star field projections, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The lighting device is designed with universal adaptability to retrofit into various pre-existing light fixtures through different mounting configurations. The single device can produce multiple lighting effects including star fields, pin-point lights, and traditional accent lighting, making it suitable for diverse applications in smaller venues without requiring specialized equipment for each effect.
2Adaptability or versatility
If sophisticated lighting systems are installed in smaller venues, then advanced lighting effects can be achieved, but extensive electrical rewiring and special equipment are required
Solution Approach 1:
The patent divides the sophisticated lighting system into a self-contained module that can be independently installed. By segmenting the system into discrete components (light source, optical element, power supply) housed in a single unit, the device can be retrofitted into existing fixtures without requiring extensive rewiring or structural modifications to the venue's electrical infrastructure.
Solution Approach 2:
The invention acts as an intermediary device that bridges between simple existing light fixtures and sophisticated lighting effects. The retrofitable design serves as a mediator, allowing advanced coherent light effects to be introduced into traditional lighting infrastructure without requiring direct integration with the building's electrical system or extensive installation work.
3Use of energy by moving object
If traditional lighting systems are used, then the installation is simple and cost-effective, but energy efficiency and advanced effects are limited
Solution Approach 1:
The patent employs a switched-mode power supply that efficiently converts electrical power to suit the coherent light source requirements. This parameter change in power conversion methodology significantly improves energy efficiency compared to traditional lighting systems. The device maintains relatively simple installation while achieving superior energy performance through optimized electrical parameters and efficient power management circuitry.
