Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent uses photogrammetry to create two-dimensional photographs of the fish from multiple angles, which are then processed into a three-dimensional digital model. This copying approach allows accurate replication of fish morphology without requiring complex traditional sculpting equipment or specialized artistic skills, resolving the contradiction between manufacturing precision and device complexity

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces traditional mechanical sculpting and modeling processes with computational algorithms that automatically generate three-dimensional models from two-dimensional photographs. This substitution of mechanical systems with computational systems eliminates the need for specialized skills while maintaining high accuracy in the final replica

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
