Current methods for manufacturing tooth bone graft materials are time-consuming, costly, and prone to bacterial contamination, with manual processes that fail to accurately control the ratio of organic and inorganic substances, leading to inefficient osteoconduction and osteoinduction, and the materials often lack strength and durability.

Innovation Solution

An automatic machine that processes tooth bone graft materials, capable of producing both block and powder types, with a system that includes a power supply, suction pump, vibrator, heat generator, and solenoid valves to control the supply of reagents and automate the manufacturing process, ensuring precise control over the ratio of organic and inorganic substances and preventing bacterial contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual work is used to manufacture tooth bone graft materials, then flexibility in handling is maintained, but manufacturing time becomes excessively long and bacterial contamination risk increases

Engineering Contradiction:
Improvemanufacturing timeVSAvoidautomation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables self-service automation where the machine automatically performs washing, sterilization, and processing of tooth bone graft materials without requiring continuous manual intervention. The automated sequence of operations including vacuum drying, chemical treatment, and sterilization cycles allows the system to service itself through programmed routines, dramatically reducing manufacturing time while maintaining sterility.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent employs a sealed processing chamber that creates a controlled inert environment during manufacturing. By maintaining vacuum or inert gas atmosphere during processing, the system prevents bacterial contamination while automating the manufacturing process, thus improving productivity without compromising sterility or requiring complex external intervention.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

2Reliability

If block-shaped graft materials with large organic substances are used, then osteoinduction is improved, but strength decreases and volume cannot be maintained

Engineering Contradiction:
Improveosteoinduction capabilityVSAvoidstructural strength
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The system applies local quality control by enabling selective processing of different regions of the tooth bone. Through controlled chemical treatment and vibration, specific areas can be optimized for either strength or osteoinduction properties. The automated process allows differential treatment zones within the same graft material, creating regions with high organic content for osteoinduction while maintaining structurally critical areas with appropriate strength characteristics.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes parameter changes in the processing conditions to control the organic-inorganic substance ratio. By adjusting vibration frequency, chemical concentration, treatment time, and temperature parameters during automated processing, the system can precisely control the composition of the graft material. This allows optimization of both strength and osteoinduction properties by tuning processing parameters rather than being constrained by fixed block shapes.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If powder type graft materials are used, then productivity and adaptability are improved, but control over substance content precision becomes more difficult

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidsubstance content control
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The automated system incorporates feedback control mechanisms that monitor and adjust processing parameters in real-time during powder graft material manufacturing. Sensors detect substance content, moisture levels, and processing progress, allowing the controller to adjust chemical dosing, vibration intensity, and treatment duration to maintain precise substance content control despite the challenges of powder form processing. This feedback loop ensures consistent quality while maintaining high productivity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical handling with automated vibrational and acoustic fields for processing powder materials. Through controlled vibration and ultrasonic treatment, the system achieves uniform distribution and processing of powder particles without manual intervention. This substitution of mechanical handling with field-based processing maintains manufacturing precision while enabling high-speed automated operation and improving productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Object-affected harmful factors

If vacuum processing is used, then bacterial contamination is prevented, but processing time increases due to vacuum establishment and maintenance

Engineering Contradiction:
Improvebacterial contamination preventionVSAvoidvacuum processing time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The system performs preliminary sealing and pre-vacuuming of the processing chamber before introducing materials. By establishing the vacuum environment in advance and pre-positioning all necessary chemicals and materials within the sealed chamber, the system minimizes the time required to maintain vacuum during actual processing. This preliminary preparation allows rapid vacuum establishment and prevents contamination without extending overall processing time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous processing where multiple operations (washing, chemical treatment, sterilization, drying) are performed in sequence without breaking the vacuum seal. The automated system maintains continuous useful action throughout the manufacturing process, eliminating the need to repeatedly establish and maintain vacuum. This continuous operation under vacuum prevents bacterial contamination while reducing total processing time compared to batch-wise vacuum processing.

Inventive Principle:
Principle #20Continuity of useful action
