Innovation Solution
A projection device with a first projection assembly comprising a first light source, a first lens, a second lens, and a light-transmitting lampshade, where the lenses are arranged on the light path and driven to rotate, utilizing irregular plano-convex lenses of different shapes to generate dynamic and variable projection effects by superimposing projection effects through the lenses and lampshade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional projection lamps use simple projection patterns, then the device complexity is low, but the projection effect is monotonous and unable to meet requirements for active atmosphere
Solution Approach 1:
The projection device is divided into multiple independent lens assemblies, each containing irregular plano-convex lenses with different shapes. Each lens assembly can independently generate different projection patterns, allowing the system to achieve diverse projection effects through combination rather than requiring a completely complex redesign of the entire device
Solution Approach 2:
The patent introduces a rotating mechanism that allows the lens assembly to rotate, dynamically changing which irregular plano-convex lenses are positioned in the light path. This dynamic adjustment enables the same physical device to produce multiple different projection patterns over time, increasing adaptability without proportionally increasing structural complexity
2Adaptability or versatility
If multiple irregular plano-convex lenses with different shapes are arranged on the light path, then diverse projection patterns are achieved, but the device complexity increases
Solution Approach 1:
Multiple irregular plano-convex lenses with different shapes are merged into a single integrated lens assembly structure. This consolidation allows the lenses to work together in sequence on the same light path, achieving complex projection patterns through the combined optical effects rather than requiring separate independent systems for each pattern type
Solution Approach 2:
The patent utilizes the spatial dimension by arranging lenses at different positions and orientations along the light path. The rotating mechanism adds temporal dimension, allowing the system to cycle through different lens configurations. This multi-dimensional approach enables pattern diversity while maintaining a relatively compact physical structure
