Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If conventional methods are used to prepare bone transplant material from extracted teeth, then the material can be prepared with complete demineralization, but the processing time requires about 10 days or more

Engineering Contradiction:

Improveprocessing timeVSAvoidpreparation efficiency

Core Design Contradiction:

Loss of timeVSProductivity

Solution Approach 1:

The patent applies parameter changes by modifying the physical conditions of sonication (adding vacuum pressure control) to dramatically accelerate the demineralization process. By changing the pressure parameter during ultrasonic treatment, the processing time is reduced from 10 days to approximately 2 hours while maintaining complete demineralization effectiveness.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent utilizes mechanical vibration through ultrasonic waves to enhance the demineralization process. The ultrasonic vibration creates cavitation effects that significantly accelerate the removal of mineral components from the tooth structure, enabling rapid preparation of bone transplant material without compromising the quality of demineralization.

Inventive Principle:

Principle #18Mechanical vibration

2Ease of operation

If the extracted tooth is processed using conventional methods, then the bone transplant material can be prepared, but additional transfer of the tooth to another site is required

Engineering Contradiction:

Improveon-site processing capabilityVSAvoidprocessing system requirements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent makes the extracted tooth serve multiple functions: it remains in the original extraction site and simultaneously functions as both the source material and the processing location. The tooth is processed in-situ without transfer, allowing the extraction site to serve dual purposes of material collection and material preparation, thereby simplifying the overall procedure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The extracted tooth is processed at the same location where it was extracted, eliminating the need for transfer to another facility. The processing system is brought to the extraction site, allowing the tooth to be prepared as a bone transplant material in-place, reducing logistical complexity and enabling immediate use.

Inventive Principle:

Principle #25Self-service

3Manufacturing precision

If chemical reagent treatment is applied to extracted teeth, then demineralization can be achieved, but the process requires extended time without vacuum sonication

Engineering Contradiction:

Improvedemineralization completenessVSAvoidtreatment duration

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent maintains continuous and intensive demineralization action by combining chemical reagent treatment with vacuum sonication. The ultrasonic waves continuously disrupt the tooth structure while chemical reagents simultaneously dissolve mineral components, creating a synergistic effect that maintains high demineralization intensity throughout the shortened 2-hour process, ensuring complete removal of mineral content.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The vacuum sonication is applied preliminarily and concurrently with chemical reagent treatment to pre-fragment and expose the mineral structure. This preliminary mechanical action creates numerous exposure sites that accelerate subsequent chemical demineralization, allowing the chemical process to complete rapidly and thoroughly within the shortened time frame.

Inventive Principle:

Principle #10Preliminary action
