Damping Ring for UV Lamp Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UV radiator units face mechanical stress issues due to vibrations and shocks, particularly in mobile applications, where plastic or rubber centering rings fail to provide adequate protection and stability, leading to potential damage of the lamp and sleeve tube.
Innovation Solution
A damping ring with a first and second side element, connected by axial portions, which can flex and compress under load, is positioned between the lamp body and the quartz tube, ensuring durable mechanical resistance and concentric alignment while allowing UV light transmission and accommodating electrical wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic or rubber centering rings are used to position the lamp inside the sleeve tube, then the lamp is centered and supported, but the mechanical resistance to shock and vibration is insufficient
Solution Approach 1:
The damping ring is made from a resilient material that combines elastic properties with damping characteristics, creating a composite functional material that simultaneously provides mechanical support, shock absorption, and vibration damping, resolving the contradiction between centering function and mechanical protection
Solution Approach 2:
The resilient damping ring is installed beforehand between the lamp body and sleeve tube to provide preventive cushioning against upcoming mechanical shocks and vibrations, protecting the lamp from damage before the stress events occur
2Use of energy by moving object
If the lamp is positioned concentrically in the sleeve tube, then UV output is maintained by preventing cooling, but mechanical stress from vibrations can still cause the lamp to hit the sleeve tube
Solution Approach 1:
The damping ring acts as an intermediary element between the lamp body and sleeve tube, providing both thermal isolation to maintain UV output and mechanical cushioning to protect against vibration-induced contact, simultaneously addressing both energy efficiency and mechanical protection
3Stability of the object's composition
If a rigid centering structure is used to prevent lamp movement, then mechanical stability is improved, but the ability to absorb shock and vibration is reduced
Solution Approach 1:
The centering structure transitions from a rigid static design to a dynamic resilient design, where the damping ring can elastically deform and adapt to mechanical stresses, maintaining lamp position stability while absorbing shock and vibration through controlled deformation
