Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If conventional ultrasonic machining systems are used, then material removal is achieved, but the system occupies large space and requires frequent maintenance

Engineering Contradiction:
Improvemaintenance frequencyVSAvoidsystem structure
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The patent combines the ultrasonic vibration source, tool holder, and machining tool into a single integrated ultrasonic machining module. The ultrasonic converter is directly coupled to the tool holder, eliminating separate components and reducing the number of parts that require maintenance. This merging of functions into one compact module directly addresses the maintenance frequency issue while simplifying the overall system structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs a nested structure where the ultrasonic converter is housed within the tool holder assembly, and the tool is mounted within the converter. This nested arrangement allows the entire ultrasonic machining system to be contained within a compact footprint, reducing the space occupation while maintaining all necessary functional components in a space-efficient configuration.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If traditional ultrasonic machining equipment is employed, then machining capability is provided, but the equipment occupies large space

Engineering Contradiction:
Improvemachining capabilityVSAvoidequipment footprint
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

By merging the ultrasonic vibration source, tool holder, and tool into a single integrated module, the patent achieves full machining capability within a compact form factor. The integration eliminates the need for separate ultrasonic generators and tool holders that would occupy additional space, thereby maintaining productivity while dramatically reducing the equipment footprint.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from a distributed, multi-component ultrasonic machining system to a compact, three-dimensionally optimized integrated module. The nested arrangement of components in vertical and radial dimensions allows the system to maintain its functional volume while presenting a much smaller horizontal footprint, effectively utilizing spatial dimensions to reduce overall equipment area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If conventional ultrasonic systems are used, then material removal is achieved, but the system is difficult to control and maintain

Engineering Contradiction:
Improvesystem controllabilityVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The integration of the ultrasonic converter directly with the tool holder creates a unified control system where vibration generation and tool positioning are inherently coordinated. This merging eliminates the complexity of coordinating separate ultrasonic generators and tool holders, improving controllability while reducing the number of interfaces that require maintenance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated ultrasonic machining module is designed with self-aligning features where the converter, tool holder, and tool automatically maintain proper positioning during operation. This self-service capability reduces the need for external adjustment mechanisms and simplifies maintenance, as the system automatically compensates for minor positioning variations without requiring complex control interventions.

Inventive Principle:
Principle #25Self-service
