Decorative Light Projecting Static and Dynamic Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative outdoor lights lack the ability to effectively project both static and dynamic lighting effects simultaneously, limiting their versatility and aesthetic appeal during holiday decorations.
Innovation Solution
A decorative light system comprising a housing with a motor-driven rotating lens module and multiple light modules, including a first light module with rotating lenses and a second light module with stationary lenses, which projects static and dynamic images by rotating the refractive lens and using film slides with negative images, allowing for the combination of static and dynamic imagery effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light module with fixed lenses is used, then the device structure is simple, but it cannot project both static and dynamic lighting effects simultaneously
Solution Approach 1:
The lighting system is divided into separate light modules: a first light module with rotating lenses for dynamic effects and a second light module with stationary lenses for static effects. This segmentation allows each module to specialize in one type of lighting effect while maintaining overall system versatility without excessive complexity
Solution Approach 2:
The decorative light device is designed to perform multiple functions by combining different light modules that can project various lighting effects (static, dynamic, colorful, monochromatic) simultaneously or independently, making the device adaptable to different decorative scenarios while managing structural complexity through modular design
2Adaptability or versatility
If a motor-driven rotating lens module is added to create dynamic effects, then lighting effect versatility is improved, but device complexity increases
Solution Approach 1:
A motor-driven rotating lens module is introduced to enable dynamic lighting effects by rotating the lenses to create moving patterns. This dynamic component is paired with stationary lens modules for static effects, allowing the system to switch between and combine dynamic and static lighting modes while managing mechanical complexity through purposeful differentiation of moving and fixed components
3Adaptability or versatility
If multiple light modules with different lens types are used, then lighting effect versatility is improved, but device complexity increases
Solution Approach 1:
Different light modules are designed with specific lens characteristics suited to their intended functions: rotating lenses for dynamic patterns, stationary lenses for static images, and beam-splitter lenses for colorful effects. Each local component is optimized for its specific role, improving overall projection capability while managing optical system complexity through functional specialization rather than uniform design
