Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing starry sky lamps do not effectively utilize the heat dissipation function of their shells, leading to potential damage or malfunction due to poor heat dissipation, which affects user experience.
Innovation Solution
A starry sky lamp design that includes a shell with a heat dissipation fan, a light-transmitting cover, and a clamping structure for the bottom and spotlight covers, along with an oxidized graphene insulation and heat dissipation coating, to enhance heat dissipation by blowing air towards the laser and utilizing the shell's surface for heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional starry sky lamp structure is used, then the lamp can project starry sky effects, but the heat dissipation effect is poor causing laser damage or malfunction
Solution Approach 1:
The shell is divided into multiple functional areas: laser mounting area with heat dissipation fins, LED light ring area, control circuit area, and air inlet/outlet channels. This segmentation allows each area to be optimized for its specific function, particularly improving heat dissipation from the laser while maintaining other lamp functions.
Solution Approach 2:
A heat dissipation fan is introduced as an intermediary component to actively move air through the heat dissipation channels. The fan creates forced convection current that accelerates heat removal from the laser and other heat-generating components, significantly improving the heat dissipation effect.
2Temperature
If heat dissipation structures are added to improve cooling, then heat dissipation effect improves, but device complexity increases
Solution Approach 1:
The shell serves multiple functions simultaneously: it provides structural support, acts as a heat dissipation radiator through integrated fins, guides airflow through built-in channels, and houses mounting positions for all components. This multi-functionality reduces the need for separate heat dissipation components, maintaining structural simplicity while improving cooling.
Solution Approach 2:
The heat dissipation fins are merged directly into the shell structure rather than being separate attachments. The air inlet and outlet channels are integrated into the shell walls. This merging approach combines the shell's structural function with heat dissipation function, reducing overall device complexity while achieving effective cooling.
