Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical force is applied to deform nanometer-scale material, then deformation can be achieved, but it becomes difficult to control the deformation degree and shape due to the minuscule scale
Solution Approach 1:
The patent replaces the conventional mechanical force application system with a particle beam irradiation system. Instead of physically contacting and forcing the nanometer-scale material to deform, a particle beam (such as ion beam) is used to irradiate the material, inducing deformation through non-mechanical means. This substitution eliminates the control difficulties associated with applying mechanical force at the nanometer scale while achieving precise deformation control through beam parameter adjustment.
2Manufacturing precision
If conventional methods like milling, etching, or deposition are used to control nanometer-scale material shape, then shape control is achievable, but these methods are not truly deformation-based and have limitations
Solution Approach 1:
The patent utilizes parameter changes in the particle beam irradiation process to achieve shape control. By adjusting parameters such as beam energy, beam current, irradiation time, and scanning pattern, the deformation characteristics of the nanometer-scale material can be precisely controlled. This approach provides greater adaptability compared to conventional methods, as the same particle beam system can deform various materials and geometries by simply changing irradiation parameters without requiring different processing tools or techniques.
