Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the storage tank is rigidly fixed to the vehicle body frame, then the stability of the storage tank is improved, but the risk of damage from vibration and twisting increases
Solution Approach 1:
The patent applies dynamics by making the fixing frame movable relative to the vehicle body frame through damping members. The fixing frame can move in the vertical direction and rotate, allowing the storage tank to adapt to vibrations and twisting dynamically rather than being rigidly constrained, thus reducing damage risk while maintaining stability.
Solution Approach 2:
The damping member acts as an intermediary between the vehicle body frame and the fixing frame. It absorbs and dampens vibrations and twisting forces, preventing them from being directly transmitted to the storage tank, thereby protecting the tank from damage while maintaining its stability.
2Object-affected harmful factors
If the damping member allows greater relative movement, then the risk of damage from vibration is reduced, but the stability of the storage tank decreases
Solution Approach 1:
The damping member changes its damping parameter dynamically based on vehicle operating conditions. When the vehicle is stationary or moving smoothly, the damping member allows greater movement to protect from vibrations. When rapid deceleration or turning is detected, the damping member increases its damping force to maintain stability, thus adapting to different conditions.
Solution Approach 2:
The control unit receives feedback signals from sensors detecting vehicle acceleration, deceleration, and turning. Based on this feedback, the control unit adjusts the damping force of the damping member in real-time, allowing greater movement during normal conditions for vibration protection while maintaining stability during maneuvers.
3Object-affected harmful factors
If a complex damping control system is implemented, then the protection from vibration and twisting is improved, but the device complexity increases
Solution Approach 1:
The damping member is designed to automatically adjust its damping force based on the vehicle's operating conditions without requiring complex external control systems. The damping member itself responds to forces applied to it, providing vibration protection through its inherent damping characteristics, thus reducing overall system complexity.
