Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bulb lamps with tungsten filaments are prone to failure due to unstable voltage, and while LED replacements reduce burnout risk, they primarily serve a single function of illumination.
Innovation Solution
A bulb lamp design incorporating a lamp shell with an annular step, a light-transmitting cover, a power panel, a lamp panel with dual circuits, an illumination module, and a sterilization module, which together provide both illumination and air sterilization/purification functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tungsten filament is used in a conventional bulb lamp, then luminous illumination can be achieved, but the bulb is prone to failure when voltage is unstable
Solution Approach 1:
The bulb lamp integrates multiple functions including illumination, air sterilization, and air purification by incorporating a sterilization module with UV-C LED and photocatalyst coating alongside the illumination LED, transforming a single-function device into a multi-functional one that addresses both reliability and versatility
2Reliability
If the internal tungsten filament is replaced with a LED bulb, then the possibility of burning out is reduced, but the bulb lamp has only a lighting effect resulting in a single use function
Solution Approach 1:
The bulb lamp integrates multiple functions including illumination, air sterilization, and air purification by incorporating a sterilization module with UV-C LED and photocatalyst coating alongside the illumination LED, transforming a single-function device into a multi-functional one that addresses both reliability and versatility
Solution Approach 2:
The illumination module and sterilization module are merged into a single bulb lamp structure, with the sterilization module comprising a UV-C LED and photocatalyst coating that work together to provide air sterilization and purification functions alongside illumination
3Adaptability or versatility
If air inlets and air outlets are provided to enable air flow through the bulb lamp, then air sterilization and purification function can be achieved, but the structural complexity increases
Solution Approach 1:
The light-transmitting cover serves dual purposes: it allows light transmission for illumination and simultaneously functions as an air outlet for the sterilization function, eliminating the need for separate air outlet structures and reducing overall structural complexity
Solution Approach 2:
The air inlet and air outlet pathways are merged with the existing bulb structure, using the lamp shell and light-transmitting cover as integral parts of the air flow system rather than adding separate dedicated air handling components
