Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle suspension systems with electrically adjustable hydraulic shock absorbers lack integrated power drive electronics, leading to increased complexity and reduced control over damping characteristics.
Innovation Solution
An integrated electronic system, including a printed circuit board assembly with power drive electronics, is electrically coupled to the shock absorber, allowing for direct control of electromechanical valves and adjustment of damping states within the shock absorber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power drive electronics are integrated into each shock absorber, then control over damping characteristics is enhanced, but device complexity increases
Solution Approach 1:
The patent integrates power drive electronics directly into each shock absorber assembly, combining previously separate components (electromechanical valves, power electronics, control circuitry) into a unified modular unit. This merging enables direct control of damping characteristics at the shock absorber level while managing complexity through integration rather than distributed separate components.
2Ease of operation
If integrated electronic systems are added to shock absorbers, then damping control is improved, but manufacturing complexity increases
Solution Approach 1:
The system is segmented into modular shock absorber units, each containing its own integrated electronics and control capabilities. This segmentation allows for standardized manufacturing of modular components that can be independently produced and then assembled, reducing overall manufacturing complexity compared to building entirely customized integrated systems.
Solution Approach 2:
The integrated electronic system is designed with universal components and standardized interfaces that can be applied across multiple shock absorber models. The power drive electronics and control architecture serve multiple functions (damping control, diagnostics, communication) within a unified platform, simplifying the manufacturing process through component reuse and standardization.
