Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydraulic suspension systems face challenges in installation and adaptability due to separately disposed components, making it difficult to configure and apply to various vehicle types, leading to increased development costs.
Innovation Solution
An electric height control device with integrated components, including an oil storage part, motor driving part, hydraulic block part, and control part, which are stacked and fixedly installed on the vehicle body, reducing the need for separate hydraulic lines and wiring, and allowing for modular configuration and application across different vehicle types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If components of hydraulic system are separately disposed, then each component can be independently manufactured and maintained, but it becomes difficult to install and connect components in vehicle with spatial constraints and increases device complexity
Solution Approach 1:
The patent integrates the reservoir, pump, and valve blocks into a single integrated control unit. The reservoir is positioned within the valve block structure, and the pump is mounted on the valve block, eliminating the need for separate component mounting and reducing installation complexity while maintaining manufacturing independence through modular design
2Reliability
If components are separately disposed with pipes and wiring, then system functionality is maintained, but spatial constraints in vehicle installation are difficult to satisfy and development cost increases
Solution Approach 1:
By combining reservoir, pump, and valve blocks into one integrated unit with internal fluid passages, the system eliminates external piping and wiring requirements, reducing spatial constraints and enabling application across different vehicle types without modification
Solution Approach 2:
The integrated control unit serves multiple functions (fluid storage, pressurization, flow control) in a single compact structure, making it universally applicable to various vehicle platforms without requiring vehicle-specific customization
3Ease of repair
If multiple separate components are used, then system redundancy and maintainability are improved, but mounting package configuration becomes difficult and development cost increases
Solution Approach 1:
The integrated control unit is designed as a modular assembly where the reservoir, pump, and valve blocks can be manufactured separately and then assembled into a single unit, maintaining manufacturing independence while simplifying installation to a single mounting operation
