Innovation Solution
A music starry sky projection lamp with a swinging transparent water pattern cover, a thumb wheel component, and a laser component, featuring a motor-driven swinging arm, rotatable pattern plates, and adjustable pattern imaging transparent covers to simulate dynamic starry sky, cloud, and water ripple effects, along with a speaker for enhanced ambiance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional projection lamp structure is used, then the structure is simple, but the projection effect is static and lacks dynamic variability
Solution Approach 1:
The patent applies the dynamics principle by introducing a swinging arm mechanism that rotates a transparent water pattern cover around a projection lamp bead. This mechanical dynamic structure enables the projection pattern to swing and change orientation, transforming a static projection into a dynamic one that can cover different areas and angles, thereby resolving the contradiction between simple structure and dynamic projection effects.
Solution Approach 2:
The patent segments the projection system into distinct functional modules: a projection lamp bead, a transparent water pattern cover with pattern pieces, a swinging arm mechanism, and a motor-driven rotation system. This segmentation allows each component to perform its specific function independently while contributing to the overall dynamic projection effect, enabling versatility without requiring complete structural redesign.
2Adaptability or versatility
If multiple projection patterns are implemented, then the usage scenes are diversified, but the device structure becomes more complex
Solution Approach 1:
The transparent water pattern cover serves multiple functions: it contains pattern pieces that can be rotated to different positions, it can be swung to different angles, and it allows light transmission while creating water-like projection effects. This multi-functionality enables a single component to provide diverse projection patterns and usage scenes without requiring separate devices for each function, thus resolving the contradiction between versatility and structural complexity.
Solution Approach 2:
The pattern pieces within the transparent water pattern cover are arranged to be rotatable, allowing users to dynamically change projection patterns by rotating the cover. This dynamic reconfiguration capability enables multiple usage scenes (such as different festival themes, seasonal patterns, or decorative styles) without adding multiple static pattern components, thereby achieving versatility with minimal structural complexity.
3Reliability
If a swinging mechanism is added to create dynamic projection, then the projection effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent implements a swinging mechanism where a transparent water pattern cover is suspended from a swinging arm that can rotate around a projection lamp bead. This dynamic structure allows the projection pattern to swing naturally, creating more effective and engaging visual effects. The mechanism uses simple rotational joints and gravity-assisted movement rather than complex motorized systems for each moving part, thereby improving projection effectiveness while controlling mechanism complexity.
