Adjustable Pivot Lever for Vehicle Vibration Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle vibration devices are inadequate for effectively compensating for brief rotations, translations, and driving on slopes, as they are primarily designed for short-term rotations and lack adjustable suspension systems.
Innovation Solution
A vehicle seat or cabin vibration device with a lower part and upper part that are spring-mounted via a damping device, featuring pivot bearings with adjustable levers, allowing the position of the pivot axis to change, enabling rotation about a fictitious or real axis in the vehicle width or longitudinal direction, and accommodating changes in vehicle dimensions to adjust for various driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed pivot point is used for suspension, then the device structure is simple, but the device cannot effectively compensate for translations and slope driving
Solution Approach 1:
The patent applies the dynamics principle by making the lever position adjustable rather than fixed. The lever can be positioned at multiple locations along the lower part, allowing the suspension system to dynamically adapt to different driving conditions such as translations and slope driving, thereby improving compensation capability while maintaining manageable complexity through discrete adjustment positions.
Solution Approach 2:
The patent implements parameter changes by varying the lever position parameter along the lower part. By changing the position parameter of the lever relative to the lower part, the system can optimize its performance for different operational scenarios including translation compensation and slope driving, transforming a static system into one with variable characteristics.
2Adaptability or versatility
If the lever position is fixed, then the manufacturing and assembly are simple, but the device cannot adapt to different driving conditions
Solution Approach 1:
The patent applies dynamics by introducing adjustability to the lever position, enabling the system to adapt to various driving conditions. The manufacturing complexity is managed by providing specific adjustment positions that can be pre-configured, balancing adaptability with ease of manufacture through standardized adjustment options.
Solution Approach 2:
The patent implements universality by designing the lower part with multiple lever attachment positions that can handle various driving scenarios. This multi-position capability allows a single device to perform multiple functions - compensating for translations, adapting to slope driving, and maintaining stability under different conditions, thereby achieving versatility without requiring multiple specialized components.
3Adaptability or versatility
If the pivot axis position is fixed, then the suspension geometry is simple, but the device cannot optimize kinematics for various driving conditions
Solution Approach 1:
The patent applies parameter changes by making the pivot axis position variable through adjustable lever locations. By changing the lever position parameter, the system can optimize its kinematic characteristics for different driving conditions such as slope driving and translation compensation, transforming a fixed-geometry suspension into one with variable kinematics.
Solution Approach 2:
The patent implements dynamics by enabling the pivot axis position to be adjusted according to driving conditions. This dynamic geometric adjustment allows the suspension system to optimize its kinematic behavior for different operational scenarios, improving adaptability while maintaining a manageable level of complexity through discrete adjustment positions.
