Flushing Head Camera Damping Mass Vibration Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rinsing heads used for examining and cleaning channels are prone to damage due to strong vibrations and water pressure, which can harm the camera installed within the housing.
Innovation Solution
The camera is integrated into a damping mass within the rinsing head's housing, using a damping compound like polyurethane or polyamide to absorb vibrations, and is connected via a frame element with non-positive locking, ensuring it is securely fixed and protected from moisture, with additional damping and encapsulation for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is directly mounted in the flushing head housing, then the structure is simple and easy to manufacture, but the camera is exposed to strong vibrations and water pressure causing damage
Solution Approach 1:
A damping mass is introduced as an intermediary element between the camera and the flushing head housing. This damping mass absorbs vibrations and mechanical stresses, protecting the camera while maintaining a relatively simple overall structure. The damping mass acts as a buffer that decouples the camera from direct mechanical contact with the housing.
Solution Approach 2:
The camera is embedded in the damping mass before the final assembly is completed. The damping mass is prepared in advance with the camera positioned within it, providing pre-cushioning against upcoming vibrations and impacts during operation. This ensures the camera is protected before any harmful vibrations occur.
2Reliability
If the camera is surrounded by damping mass, then vibration damping is improved, but moisture protection becomes more critical
Solution Approach 1:
The damping mass is formulated as a composite material that simultaneously provides vibration damping and moisture protection. By incorporating hydrophobic additives or creating a closed-cell foam structure, the damping mass performs dual functions: absorbing mechanical vibrations while preventing water and moisture from reaching the camera.
Solution Approach 2:
The damping mass is designed to serve multiple functions simultaneously: it provides vibration damping, shock absorption, and moisture protection. This multi-functional approach eliminates the need for separate protective layers, simplifying the overall structure while addressing both vibration and moisture hazards.
3Stability of the object's composition
If the damping mass is firmly locked to the housing, then the camera is securely fixed, but vibrations are transmitted more directly to the camera
Solution Approach 1:
The mounting structure is segmented into distinct functional zones: the damping mass is firmly locked to the housing for stable positioning, while the camera is embedded within the damping mass with vibration isolation. This segmentation allows different parts of the mounting structure to have different mechanical properties - rigid for positioning, compliant for vibration isolation.
Solution Approach 2:
The damping mass exhibits different mechanical properties in different regions: it is firmly anchored to the housing at the mounting interface for stable positioning, while the region surrounding the camera provides soft, compliant vibration isolation. This local differentiation of mechanical properties simultaneously achieves secure fixation and vibration protection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively dampens vibrations, preventing camera damage and protecting it from moisture ingress, ensuring long-term operational reliability and reducing the risk of water penetration into the camera's electronics.
Implementation Method 1
The damping mass is preferably a plastic material with a Shore hardness A of 60 to 100, preferably 75 to 85 or a Shore hardness D of around 40 to 60, preferably 45 to 55. Vibrations that occur during operation are sufficiently dampened so that the camera remains undamaged
Implementation Method 2
The camera is arranged in a damping mass in the housing of the rinsing head. The damping compound is preferably a casting compound that largely surrounds the camera
