Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing starry sky and galaxy lamps have poor projection effects and are not easily maintainable due to their integrated structure, which limits their ability to simulate a real star cloud effect and hinders maintenance when faults occur.
Innovation Solution
A projection lamp design that includes a lamp holder, light source, optical lens, and casings with clamping slots and blocks, allowing for assembly and disassembly, and featuring a projection plate with starry sky and galaxy patterns to simulate a real star cloud effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an integrated structure is used for the projection lamp, then the structure is simple and compact, but it is not easy to disassemble and maintain when faults occur
Solution Approach 1:
The lampshade is divided into multiple detachable parts (first lampshade part, second lampshade part, third lampshade part) that can be separated from each other and from the lamp body. This segmentation allows users to access internal components for maintenance while keeping the overall structure compact when assembled, resolving the contradiction between structural simplicity and ease of repair.
2Device complexity
If hollow lampshades are used for pattern projection, then the lamp structure is simple, but the projection effect is poor and cannot simulate real star clouds
Solution Approach 1:
A projection plate is introduced as an intermediary component between the light source and the lampshade. The projection plate contains precise star cloud patterns and can be detachably installed on the inner surface of the lampshade. This intermediary element enables high-quality projection effects while maintaining the simplicity of the overall lamp structure, as the projection plate can be separately manufactured and installed.
3Ease of manufacture
If the lampshade is made as a single integrated piece, then manufacturing is simple, but overhaul and maintenance are not conducive when faults occur
Solution Approach 1:
The lampshade is segmented into multiple detachable portions (first, second, and third lampshade parts) connected through specific connection structures. This segmentation maintains manufacturing simplicity through modular assembly while enabling easy maintenance by allowing users to detach and access internal components without disassembling the entire lampshade.
Solution Approach 2:
The lampshade transitions from a static integrated structure to a dynamic detachable structure. The connection structures between lampshade parts allow for easy assembly and disassembly, providing flexibility for maintenance while maintaining structural integrity during use. This dynamic design resolves the contradiction between manufacturing simplicity and maintenance accessibility.
