Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrical means are used to regulate electron channels for friction energy dissipation, then frictional characteristics can be regulated, but electrostatic force interferes with the regulation accuracy
Solution Approach 1:
The patent replaces electrical regulation methods with electron beam irradiation to control friction. The electron beam modifies the electronic structure of the friction pair surfaces, thereby regulating frictional characteristics without introducing electrostatic force interference that plagues electrical regulation methods.
Solution Approach 2:
The patent changes the regulation mechanism from electrical parameters (voltage, current) to electron beam parameters (accelerating voltage, beam current, irradiation time). By controlling these parameters, the electronic characteristics of the friction surfaces are modified to achieve desired friction regulation without electrostatic interference.
2Adaptability or versatility
If bias voltage is applied between friction pair to regulate friction, then electron channels for energy dissipation can be controlled, but the method complexity increases
Solution Approach 1:
The electron beam system serves multiple functions: it irradiates the friction pair to modify electronic structure, enables friction regulation, and allows control over a wide range of friction values by adjusting beam parameters. This single tool replaces complex electrical regulation systems requiring multiple components.
Solution Approach 2:
The patent utilizes adjustable electron beam parameters (accelerating voltage, beam current, irradiation duration) to achieve versatile friction control. By varying these parameters, different frictional states can be obtained, providing adaptability without increasing system complexity.
