Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed suspension system is used in vehicles designed for rearward loading, then the vehicle structure is simple, but the vehicle tilts when loaded causing reduced front downforce and braking performance
Solution Approach 1:
The patent applies dynamics by making the suspension mounting component vertically adjustable rather than fixed. The electric motor drives a lead screw mechanism that enables the suspension mounting component to move vertically along the bracket, allowing the system to adapt its position dynamically in response to load conditions and maintain vehicle levelness.
Solution Approach 2:
The patent replaces traditional mechanical suspension adjustment mechanisms with an electric motor-driven lead screw system. This substitution enables automated vertical positioning of the suspension mounting component, eliminating the need for manual mechanical adjustment while maintaining system stability.
2Loss of energy
If a fixed suspension system is used, then the device complexity is low, but fuel consumption increases due to higher front end and increased drag coefficient
Solution Approach 1:
The system dynamically adjusts the suspension mounting component's vertical position to maintain optimal vehicle attitude. By keeping the front end lower through automated adjustment, the system reduces drag coefficient and consequently decreases energy loss from increased fuel consumption.
3Reliability
If the suspension mounting component is made vertically adjustable, then vehicle stability is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical adjustment systems with an electric motor-driven lead screw mechanism. This substitution improves reliability by enabling automated, precise vertical positioning of the suspension mounting component, ensuring optimal braking performance through maintained vehicle levelness.
Solution Approach 2:
The system incorporates sensors that automatically detect vehicle tilt and load conditions, triggering the electric motor to adjust the suspension mounting component's position without manual intervention. This self-service capability maintains braking performance while managing system complexity through automation.
4Stability of the object's composition
If an electric motor is added to adjust the suspension vertically, then ride stability is enhanced, but the weight of the vehicle increases
Solution Approach 1:
The patent introduces a lightweight electric motor that enables dynamic vertical adjustment of the suspension mounting component. This dynamic capability enhances ride stability by maintaining optimal vehicle attitude under varying load conditions, while the electric motor's lightweight design minimizes the weight penalty.
