Engineering Contradiction Analysis
1Manufacturing precision
If ultra-high vacuum and ultra-low temperature environments are used for atomic-precision manufacturing, then manufacturing precision can be improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent changes the environmental parameters from ultra-high vacuum and ultra-low temperature to atmospheric pressure and room temperature conditions. This is achieved by using a liquid environment with controlled composition that enables atomic-precision machining without requiring complex vacuum and cryogenic systems, thereby reducing device complexity while maintaining manufacturing precision
Solution Approach 2:
The patent introduces a liquid medium as an intermediary between the cutting tool and workpiece. This liquid environment acts as a mediator that enables precise atomic-level material removal through controlled chemical reactions and mechanical forces, eliminating the need for extreme environmental conditions while maintaining atomic-precision
2Manufacturing precision
If masks are used for area selection in nanomanufacturing, then manufacturing precision can be improved, but processing time and complexity increase
Solution Approach 1:
The patent extracts and eliminates the mask component from the manufacturing system. Instead of using masks for area selection, the invention employs direct digital control of the liquid environment and cutting tool positioning to achieve precise area selection, thereby removing the time-consuming mask fabrication and alignment steps
Solution Approach 2:
The patent replaces the mechanical mask-based area selection system with a field-based control system. Through controlled electric, magnetic, or acoustic fields acting on the liquid medium, precise area selection is achieved without physical masks, significantly reducing processing time and complexity
3Productivity
If conventional material removal methods are used, then manufacturing efficiency can be improved, but subsurface lattice damage occurs
Solution Approach 1:
The patent converts the potential harm of mechanical contact into a beneficial process by using controlled liquid-mediated material removal. The liquid environment allows for extremely gentle, controlled atomic-level removal that eliminates subsurface damage while maintaining efficient material removal rates through optimized process parameters
Solution Approach 2:
The patent changes the material removal mechanism from direct mechanical contact to a controlled chemical-mechanical process mediated by the liquid environment. This parameter change enables high removal rates without the subsurface lattice damage typically associated with conventional mechanical machining methods
4Manufacturing precision
If single-point diamond turning is used for material removal, then manufacturing precision can be improved, but material removal depth is limited to nano scale
Solution Approach 1:
The patent merges chemical dissolution and mechanical removal processes into a unified liquid-mediated machining system. This combination allows the process to achieve both the precision of chemical methods and the depth capability of mechanical methods, overcoming the nano-scale depth limitation of single-point diamond turning
