Vibration Isolation Device for Moving Body Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration isolation devices are inadequate for autonomous-running-type vehicles equipped with monitoring devices, which require effective isolation of both vertical and horizontal vibrations to prevent mechanical failures and image blurring during operation on uneven terrain.
Innovation Solution
A vibration isolation device comprising a lower plate, an upper plate, elastic members between them, and regulating members that include pins and loose-fit holes to effectively isolate horizontal vibrations, with the elastic members handling vertical vibrations and the regulating members managing horizontal movements through strategic placement and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-precision cameras are mounted on moving bodies, then monitoring quality improves, but image blurring due to vibrations increases
Solution Approach 1:
The vibration isolation system is segmented to provide direction-specific damping: elastic members handle vertical shocks that would cause camera bounce, while regulating members constrain horizontal movements during acceleration and deceleration. This segmented approach protects the high-precision camera from multi-directional vibrations that would otherwise cause image blurring.
Solution Approach 2:
The vibration isolation device provides beforehand cushioning by pre-installing elastic members and regulating members that are ready to absorb and constrain vibrations before they reach the camera. This prior cushioning protects the camera from both vertical shocks and horizontal inertial forces during operation on uneven terrain.
2Object-affected harmful factors
If vibration isolation devices are added to moving bodies, then vibration protection improves, but device complexity increases
Solution Approach 1:
The isolation mechanism is segmented into simple, discrete components: elastic members (springs) for vertical isolation and regulating members (pin-hole constraints) for horizontal isolation. This segmentation uses basic mechanical elements rather than complex active control systems, achieving effective vibration protection while maintaining relatively simple device structure.
Solution Approach 2:
The regulating member with pin-hole configuration serves multiple functions: it constrains horizontal vibrations during acceleration and deceleration, provides structural support between upper and lower plates, and maintains alignment of the mounted device. This multi-functionality reduces the need for additional separate components, simplifying the overall device complexity.
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
The device achieves significant vibration isolation across both vertical and horizontal axes, preventing mechanical failures and image blurring, even during acceleration, deceleration, and unexpected shocks, while reducing manufacturing costs by optimizing component placement and usage.
Implementation Method 1
elastic members interposed between the lower plate and the upper plate and each fixed to the lower plate and the upper plate
Implementation Method 2
isolating up-down (i.e. perpendicular) vibrations mainly with the elastic members
Implementation Method 3
the loose-fit hole is loosely fitted on the regulating pin
Implementation Method 4
isolating front-back and right-left (i.e. horizontal) vibrations (specifically, the horizontal movement due to the force of inertia that is received during acceleration, deceleration, or the like of the moving body)
