Solution Overview
Problem
The existing method of repeatedly replacing lampshades or light sources to meet different color needs is cumbersome, leading to low color-changing efficiency and increased costs.
Innovation Solution
A color-changing lampshade with a color-changing coating, such as an electrochromic, thermosensitive, or photosensitive layer, that changes color without replacing the lampshade or light source, integrated with a lamp that includes a light source, reflective component, and a detachable upper cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lampshades or light sources are repeatedly replaced to meet different color needs, then color variety is achieved, but color-changing efficiency decreases and operation time increases
Solution Approach 1:
The patent applies color-changing coatings (electrochromic, thermosensitive, or photosensitive) directly on the lampshade surface, enabling the lampshade to change colors without replacement. This resolves the contradiction by maintaining color variety while eliminating the time-consuming replacement process, thus improving color-changing efficiency.
Solution Approach 2:
The patent changes the optical parameters of the lampshade by applying functional coatings that respond to external stimuli (electricity, temperature, light). This allows the same lampshade to exhibit different color states, achieving color variety without physical replacement and improving operational efficiency.
2Adaptability or versatility
If multiple lampshades of different colors are prepared, then color needs are met, but device complexity and cost increase
Solution Approach 1:
The patent makes a single lampshade multi-functional by applying color-changing coatings that respond to different stimuli. One lampshade can produce multiple colors, eliminating the need to prepare and manage multiple lampshades of different colors, thus reducing device complexity while maintaining color variety.
Solution Approach 2:
By coating the lampshade with color-changing materials, a single lampshade can transform into multiple color states. This eliminates the need to maintain an inventory of multiple colored lampshades, simplifying the system while preserving adaptability to different color needs.
3Adaptability or versatility
If lampshades are frequently replaced, then color changes are achieved, but assembly reliability decreases
Solution Approach 1:
The patent applies color-changing coatings directly to the lampshade, making the color-changing capability an integral part of the lampshade structure. This eliminates repeated assembly and disassembly operations, thereby maintaining assembly reliability while achieving color changing capability.
