Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods (degreasing, enzymatic hydrolysis, mechanical impact, ball milling, high-speed airflow pulverization, sieving) are used to produce bone powder, then the process can produce bone powder, but the process is complicated, takes a long time (4-30 h), and the bone powder yield is low
Solution Approach 1:
The patent utilizes high-pressure steam (phase: compressed gas) penetrating into bone tissue, followed by instantaneous pressure relief that causes steam expansion and tissue rupture. This phase transition-based approach replaces complex mechanical processing steps with a thermodynamic process that achieves rapid bone powder production in 5-20 minutes, significantly improving productivity while simplifying the process flow
Solution Approach 2:
The invention replaces traditional mechanical impact, ball milling, and high-speed airflow pulverization with a thermal-mechanical system using high-pressure steam hydrolysis. The steam under pressure penetrates and hydrolyzes bone tissue, and instantaneous pressure relief creates mechanical disruption through expansion, eliminating the need for multiple mechanical processing stages
2Reliability
If conventional methods are used to produce bone powder, then the process can be completed, but the bone powder is difficult to dissolve and the absorption rate is low
Solution Approach 1:
The patent changes the physical and chemical parameters of bone tissue through high-pressure steam treatment. The steam penetrates bone tissue at high pressure, causing protein denaturation, collagen hydrolysis, and mineral dissolution. This parameter change transforms the bone structure into a more soluble form, improving absorption rate while maintaining production efficiency
Solution Approach 2:
The invention creates a composite structure in the bone powder through high-pressure steam treatment, where organic components (proteins, collagen) and inorganic components (minerals) are integrated in a new configuration. This composite structure improves solubility and absorption rate compared to mechanically ground bone powder
3Productivity
If high-pressure hydrolysis-instantaneous pressure relief technology is used, then the process time is shortened and productivity is improved, but additional equipment for pressure control is required
Solution Approach 1:
The system utilizes the bone material itself as the pressure-containing vessel. The bone tissue's own structure contains the high-pressure steam during hydrolysis, and the instantaneous pressure relief is achieved by releasing the steam through controlled valves. This self-service approach eliminates the need for separate high-pressure containment vessels, reducing equipment complexity while maintaining high productivity
