Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat and driver's cab mounting systems fail to effectively absorb and dampen multi-dimensional rotational and translational movements, leading to discomfort and potential physical injury for drivers in professional applications, particularly in vehicles with high seating positions and long hours of operation.
Innovation Solution
A vehicle oscillation device with a sprung multipoint mounting system, combining elastomer and fluid spring/damping elements, arranged in a multipiece design to provide multi-dimensional springing and damping capabilities, allowing for adjustable spring characteristics and efficient absorption of rotational and vertical/horizontal movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional springing and damping systems are used for vehicle seats, then basic vertical support is provided, but multi-dimensional rotational and translational movements cannot be effectively absorbed
Solution Approach 1:
The mounting system is divided into multiple independent mounting points (at least two, preferably three or four) distributed around the perimeter of the seat base. Each mounting point contains separate springing and damping elements, allowing independent action in different directions and rotational modes, thereby achieving multi-dimensional movement absorption through segmented functional units.
Solution Approach 2:
Each mounting point is designed to perform multiple functions simultaneously: it provides both springing (for shock absorption) and damping (for motion control), and can handle vertical, longitudinal, and transverse movements as well as rotational movements. This multi-functional design allows a single mounting system to address all six degrees of freedom without requiring separate specialized components for each function.
2Reliability
If multiple separate springing and damping components are used, then comprehensive movement absorption is achieved, but the mounting system becomes more complex and space-consuming
Solution Approach 1:
The springing elements and damping elements are merged into integrated mounting point assemblies. The springing component (such as a spring or elastomer element) and the damping component (such as a damper or viscous element) are positioned in close proximity and work together within each mounting point, reducing the overall space required compared to completely separate systems while maintaining comprehensive movement absorption capability.
Solution Approach 2:
The damping elements are positioned within or around the springing elements at each mounting point. For example, dampers can be nested within spring assemblies or positioned in the same mounting location, allowing the damping function to be incorporated without significantly increasing the external dimensions of the mounting system, thus saving space while maintaining reliability.
3Ease of operation
If standard mounting systems are used, then simple installation is maintained, but rotative springing and damping of the driver's cab cannot be achieved
Solution Approach 1:
The mounting system is segmented into multiple independent mounting points that can be individually installed at predetermined locations around the seat base perimeter. Each mounting point is a self-contained unit with standardized connection interfaces, allowing for relatively simple installation while the collective arrangement of multiple points provides the rotative springing and damping capability that would be impossible with a single simple mounting.
Solution Approach 2:
Each mounting point is designed as a universal assembly that can handle multiple types of movements (vertical, longitudinal, transverse, and rotational) through its integrated springing and damping elements. This multi-functional design allows the same basic mounting point structure to be used throughout the system, simplifying installation procedures while achieving complex rotative movement absorption through the coordinated action of multiple mounting points.
