Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional projection lamps focus on achieving diversification of patterns, then pattern presentation is improved, but lighting effect diversity remains limited and visual experience quality is insufficient
Solution Approach 1:
The patent employs rotating optical path plates with different patterns of light-transmitting holes and light-transmitting areas. By dynamically changing the arrangement and orientation of these light-transmitting features through rotation, the system achieves diverse lighting effects including meteor shooting, meteor shower, and starry sky effects without requiring multiple separate optical systems, thus improving lighting effect diversity while controlling device complexity
Solution Approach 2:
The optical system is segmented into multiple optical path plates, each with specific light-transmitting hole arrangements. The first optical path plate has holes arranged in a first pattern while the second optical path plate has holes arranged in a second pattern. This segmentation allows each plate to contribute specific lighting characteristics, and their combination produces diverse effects while keeping individual components relatively simple
2Adaptability or versatility
If conventional projection lamps use fixed optical paths, then device structure is simple, but lighting effects are single and lack dynamic visual experience
Solution Approach 1:
The patent introduces rotating optical path plates that can change their orientation and position dynamically. The first optical path plate rotates around a first rotation axis while the second optical path plate rotates around a second rotation axis. This dynamic configuration allows the system to produce various lighting effects such as meteor shooting, meteor shower, and starry sky effects without requiring complex manual operation, as the rotation is controlled automatically to achieve the desired visual experiences
