Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If internal combustion engines are used to power barrier transfer machines, then the machines can operate with sufficient power, but they produce harmful pollution, excessive noise, and are difficult to control precisely
Solution Approach 1:
The patent replaces internal combustion engines with electric motors to power the barrier transfer machine. This substitution eliminates harmful emissions and noise while providing precise control through electrical systems. The electric motors are controlled by a control system that can precisely regulate speed and torque, enabling accurate positioning and operation of the barrier transfer machine.
2Use of energy by moving object
If internal combustion engines are used, then the machines have sufficient power, but they are inefficient and produce harmful pollution
Solution Approach 1:
The patent substitutes electric motors for internal combustion engines, dramatically improving energy efficiency by eliminating the inefficiencies of combustion processes. Electric motors convert electrical energy to mechanical energy with much higher efficiency, and when powered by renewable sources or the grid, they produce no direct harmful emissions at the point of use.
Solution Approach 2:
The patent changes the energy source parameter from chemical energy (fuel) to electrical energy. This parameter change fundamentally improves both efficiency and environmental performance, as electrical energy can be generated from clean sources and delivered with minimal loss through the electrical grid.
3Ease of operation
If traditional barrier transfer machines are used, then they can move road barriers, but they are difficult to control precisely
Solution Approach 1:
The patent replaces mechanical control systems with electrical control systems. Electric motors provide inherent precision control capabilities through electronic control of voltage, current, and frequency. The control system can precisely regulate motor speed and torque, enabling accurate positioning and smooth operation of the barrier transfer machine without the mechanical linkages and control complexities of traditional systems.
