Solution Overview
Problem
Active chassis systems face challenges in mounting motor-pump units due to installation space constraints, requiring remote placement which complicates hydraulic and electrical connections.
Innovation Solution
A compact, pre-mountable device comprising two identical motor-pump units firmly connected via connecting components or a common housing, allowing for simplified installation and reduced mounting effort by integrating both units as a single component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motor-pump units are mounted directly at each shock absorber, then control precision is improved, but installation space requirements increase and mounting complexity increases
Solution Approach 1:
The patent combines two separate motor-pump units into a single integrated unit that can control two shock absorbers. This merging approach reduces the total installation space while maintaining the ability to precisely control each shock absorber individually through separate control ports.
Solution Approach 2:
The integrated motor-pump unit is designed with multiple control ports (first and second control ports) that enable it to perform multiple functions - controlling two different shock absorbers simultaneously. This multi-functionality allows the unit to maintain precise control over each shock absorber while reducing overall system complexity and space requirements.
2Area of stationary object
If motor-pump units are placed remote from shock absorbers, then installation space is reduced, but hydraulic connection complexity and electrical cabling complexity increase
Solution Approach 1:
The patent integrates the motor-pump unit with the shock absorber assembly, eliminating the need for long hydraulic lines and electrical cables. This merging of functions reduces mounting complexity while maintaining space efficiency.
Solution Approach 2:
The integrated unit is designed with separate control ports for each shock absorber, allowing independent control while maintaining a compact unified structure. This segmentation of control functions within an integrated body reduces the complexity of hydraulic and electrical connections.
3Adaptability or versatility
If individual motor-pump units are mounted for each shock absorber, then control independence is improved, but mounting time and mounting effort increase
Solution Approach 1:
The patent combines two motor-pump units into one integrated assembly that maintains independent control over two shock absorbers through separate control ports. This allows the unit to be installed as a single component, significantly reducing mounting time and effort while preserving control independence.
Solution Approach 2:
The motor-pump units are pre-integrated into a unified assembly with all necessary hydraulic and electrical connections prepared in advance. This preliminary integration allows for rapid installation as a single unit rather than requiring separate mounting and connection of individual units.
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 solution reduces mounting time and complexity, ensuring correct hydraulic and electrical connections while maintaining efficient operation for controlling two shock absorbers and enabling energy recuperation.
Implementation Method 1
by pumping hydraulic fluid, for example pitching and/or rolling movements of the vehicle can be counteracted
Implementation Method 2
such an arrangement of shock absorber, hydraulic pump and electric motor can in principle also be used to feed electrical energy obtained by recuperation back into the vehicle's onboard electrical system
