Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual determination of block-out direction is performed for each prosthesis, then the undercut effect can be reduced for that specific case, but the manufacturing efficiency decreases and retention power becomes non-uniform across multiple oral cavities

Engineering Contradiction:

Improveretention power uniformityVSAvoidmanufacturing efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent changes the parameter of insertion direction from being manually determined on a case-by-case basis to being automatically determined based on calculated undercut areas. The system calculates the undercut area for different insertion directions and selects the direction with the minimum undercut area, thereby standardizing the parameter selection process across multiple prostheses while maintaining optimal retention power for each case

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system enables self-service by automatically determining the optimal insertion direction without requiring manual intervention. The computer calculates the undercut areas and determines the best insertion direction based on the calculated data, eliminating the need for manual block-out direction determination while ensuring consistent retention power across multiple oral cavities

Inventive Principle:

Principle #25Self-service

2Reliability

If block-out direction is determined manually for each prosthesis, then the specific undercut characteristics can be addressed, but the process complexity increases and time consumption increases

Engineering Contradiction:

Improveretention powerVSAvoidtime for determining insertion direction

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical process of determining insertion direction with an automated computer-based calculation system. The computer calculates undercut areas for different insertion directions and determines the optimal direction automatically, substituting manual assessment and decision-making with computational analysis, thereby reducing time consumption while maintaining or improving retention power reliability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary computational system that mediates between the raw scan data and the final insertion direction determination. The computer acts as an intermediary by calculating undercut areas for various insertion directions and selecting the optimal direction based on these calculations, eliminating the need for direct manual determination while ensuring reliable retention power

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If different insertion directions are used for different oral cavities to address undercuts, then the undercut effect is reduced, but the manufacturing process becomes more complex and less standardized

Engineering Contradiction:

Improvestandardization of manufacturing processVSAvoidcomplexity of determining block-out direction

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent standardizes the manufacturing process by changing from manual determination of insertion direction to automated calculation based on undercut area. The computer calculates the undercut area for different insertion directions and determines the optimal direction, creating a standardized procedure that can be consistently applied across multiple oral cavities while accounting for individual undercut characteristics

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a universal method for determining insertion direction that can be applied to any oral cavity. The computer-based system universally calculates undercut areas and determines optimal insertion directions for different cases, providing a multi-functional solution that handles various undercut scenarios while maintaining manufacturing standardization

Inventive Principle:
