Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative outdoor spotlights lack the ability to project dynamic, multi-colored lighting patterns effectively, limiting their decorative and aesthetic appeal during holiday seasons.
Innovation Solution
A decorative light comprising a lamp case with a rotating beam splitter and a lighting module of LEDs, coupled with a motor and a control unit, along with a convertible support stand that can change configurations from collapsed to expanded, allowing for stable and adjustable placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a decorative outdoor spotlight uses a static beam splitter and single-color light source, then the device complexity is low, but the lighting effect is static and lacks dynamic multi-colored patterns
Solution Approach 1:
The beam splitter is made rotatable instead of static, allowing it to dynamically redirect light beams in different directions. The motor rotates the beam splitter to create moving light patterns across the ceiling, transforming the static lighting effect into a dynamic one that simulates celestial movements.
Solution Approach 2:
Multiple light sources of different colors (red, green, blue LEDs) are integrated into the device, and the beam splitter redirects these different colored lights to create multi-colored lighting patterns. This allows the device to project various colors simultaneously or sequentially, enhancing the decorative lighting effect.
2Stability of the object's composition
If the support base is always in expanded tripod configuration, then the stability is high, but the ease of operation and storage is reduced
Solution Approach 1:
The support base is designed with movable auxiliary posts that can transition between extended and retracted positions. The hinge mechanism allows the auxiliary posts to be easily extended for stable operation or retracted for compact storage, providing dynamic adaptability between stability and ease of operation modes.
Solution Approach 2:
The support base is divided into separate components: a primary post and two auxiliary posts that can independently move relative to each other. This segmentation allows the auxiliary posts to be extended or retracted independently, enabling the base to transform between expanded tripod configuration for stability and collapsed configuration for easy storage and portability.
3Stability of the object's composition
If the auxiliary posts are always extended, then the stability for outdoor placement is maximized, but the device complexity and space requirement increase
Solution Approach 1:
The auxiliary posts are designed to be dynamically extendable and retractable. When extended, they provide maximum stability for outdoor placement; when retracted, they minimize the space requirement for storage and transport. This dynamic configuration allows the device to adapt its volume based on operational needs.
Solution Approach 2:
The auxiliary posts can be nested or folded against the primary post when not in use, similar to a nested doll structure. This nesting capability allows the support base to collapse into a compact form that minimizes space requirements while maintaining the ability to expand into a stable tripod configuration when needed.
