Vibration Dampening Gasket Mount for HD Camera Jello Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional HD video cameras using CMOS technology experience undesirable rolling shutter distortion, known as the 'jello effect,' due to vibrations and air buffeting, which causes wobble in recorded video.
Innovation Solution
A camera mounting system featuring a central mounting post with first and second vibration dampening gaskets sandwiching a mounting plate, and a backing plate, along with a camera mounting stud and fasteners, to absorb and isolate vibrations, thereby reducing wobble distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is mounted rigidly to the vehicle, then the camera remains stable and secure, but vibrations are transmitted directly to the camera causing wobble distortion
Solution Approach 1:
The patent introduces vibration dampening gaskets as intermediary elements between the camera and the mounting structure. These gaskets act as mediators that decouple the rigid connection, allowing the camera to remain securely mounted while blocking the transmission of harmful vibrations. The gaskets are positioned at multiple points in the mounting assembly to effectively isolate the camera from vibration sources.
Solution Approach 2:
The patent changes the physical parameters of the mounting system by incorporating compliant, vibration-absorbing materials with specific damping properties. The gaskets are selected with appropriate durometer ratings and material characteristics to optimize vibration attenuation while maintaining secure camera attachment. This parameter change transforms the mounting system from purely rigid to a hybrid rigid-compliant structure.
2Object-affected harmful factors
If vibration dampening materials are added to the mounting system, then vibration isolation is improved, but the device complexity increases
Solution Approach 1:
The patent divides the mounting system into distinct functional segments: rigid mounting components for structural support, compliant gasket layers for vibration isolation, and fastening elements for secure attachment. This segmentation allows each component to be optimized for its specific function while maintaining overall system simplicity. The gaskets are positioned at specific locations where vibration transmission occurs, rather than requiring complete system redesign.
Solution Approach 2:
The patent employs composite mounting structures that combine rigid materials (metal or hard plastic mounting plates and brackets) with compliant vibration-dampening materials (rubber or foam gaskets). This composite approach creates a multi-functional mounting assembly that provides both structural support and vibration isolation without requiring separate complex systems for each function.

AI summary
A high definition video camera mounting system includes the camera fastened to a camera mount assembly via a central mounting post. The mounting assembly includes a first vibration dampening gasket, a second vibration dampening gasket, a mounting plate sandwiched between the first and second gaskets, and a backing plate disposed behind one of the gaskets. The mounting system allows a camera to capture HD video while mounted to a vehicle or aircraft without experiencing an unacceptable amount of wobble distortion effect. The mounting system can be fastened to an adjustable angle block.
