Engineering Contradiction Analysis
1Reliability
If different configurations are used for different types of auxiliary drivers (air cylinders, hydraulic cylinders, rotary hydraulic dampers), then each driver type can be optimized for its specific function, but manufacturing costs increase and device complexity increases
Solution Approach 1:
The patent implements a universal detection configuration that can detect the bending angle of the knee unit regardless of the type of auxiliary driver used. The detection system measures the relative position between link units and calculates the bending angle through mathematical transformation, making it compatible with air cylinders, hydraulic cylinders, and rotary hydraulic dampers without requiring driver-specific detection mechanisms. This universal approach reduces manufacturing costs by allowing a single configuration to be used across various product groups while maintaining optimized performance for each driver type through software-level adaptations.
2Reliability
If different configurations are used for different types of auxiliary drivers, then each driver type can be optimized, but device complexity increases
Solution Approach 1:
The patent employs a unified detection architecture that interfaces with multiple types of auxiliary drivers through a common methodology. The system detects relative positions between link units using consistent sensors and calculates bending angles through standardized mathematical transformations. This universal configuration reduces device complexity by eliminating the need for multiple specialized detection systems, while still providing optimized control for different driver types through adaptable control algorithms that interpret the universal detection data appropriately for each specific driver configuration.
