Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If carbon thin line probes are used for scanning probe microscopes, then high aspect ratio and atomic order measurement resolution are achieved, but durability and reliability are insufficient
Solution Approach 1:
The patent creates a composite structure by integrating metal atoms within the carbon nanotube lattice. The metal atoms are incorporated during carbon nanotube formation, creating a hybrid material that combines the high aspect ratio and measurement precision of carbon nanotubes with the durability and reliability of metal reinforcement, resolving the contradiction between measurement precision and reliability
Solution Approach 2:
The patent alters the internal structure parameter of the carbon nanotube by introducing metal atoms at specific positions within the nanotube lattice. This parameter change strengthens the nanotube structure without compromising its external dimensions or measurement capabilities, thereby improving durability while maintaining measurement resolution
2Adaptability or versatility
If metal ultrafine particles are fixed to CNT terminal end, then magnetic characteristics are imparted, but manufacturing complexity increases and batch processing becomes difficult
Solution Approach 1:
The patent incorporates metal atoms into the carbon nanotube structure during the carbon nanotube formation process itself, rather than adding them afterward. This preliminary action integrates magnetic functionality directly into the manufacturing process, enabling batch production of magnetized probes without requiring separate complex assembly steps
Solution Approach 2:
The patent merges the carbon nanotube formation process with metal atom incorporation into a single integrated process. By combining these two operations, the patent eliminates the need for separate steps to add magnetic properties, thereby reducing manufacturing complexity while maintaining magnetic functionality
3Reliability
If metal is incorporated into carbon nanotube, then durability and magnetic properties are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by selectively placing metal atoms at specific positions within the carbon nanotube structure rather than uniformly distributing them throughout. This localized incorporation method ensures that metal atoms are positioned where they provide maximum structural reinforcement and magnetic functionality, while maintaining control over their distribution to avoid excessive manufacturing precision requirements

Implementation Method 1
CNT having a high aspect ratio of several nanometers to several- ten nanometers in diameter and several μm to several-ten μm in length can now be formed using thermal decomposition or arc discharge
Implementation Method 2
CNT having a high aspect ratio of several nanometers to several- ten nanometers in diameter and several μm to several-ten μm in length can now be formed using thermal decomposition or arc discharge
Implementation Method 3
by causing a flow of C6H6 gas while maintaining a vacuum, a CNT 104 is formed on the lower end of a Ni ultrafine particle 103 by means of dehydro catalytic reaction
Implementation Method 4
when irradiated by an electron beam, is denatured and becomes a fusion bonding portion so that it is fixed by means of thermal fusion bonding to the probe of cantilever
Implementation Method 5
when an electron beam is irradiated onto the vicinity of CNT at the interior of an electron microscope where a carbon compound occurs as impurity, a coating film consisting of a carbon coat is deposited over a proximal end portion of CNT whereby CNT is firmly fixed to the probe through the coating film
