Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional air circulation methods are used in bulk food processing, then the processing system maintains simple structure, but air flow efficiency is insufficient leading to poor pasteurization effectiveness
Solution Approach 1:
The patent applies asymmetry by positioning the axial fan at an angled location rather than symmetrically in the center of the processing chamber. This asymmetric placement creates optimized air flow patterns that improve pasteurization efficiency by directing air circulation more effectively across the product bed, resolving the contradiction between maintaining simple structure and achieving high productivity.
Solution Approach 2:
The patent introduces a new spatial dimension by using an angled axial fan that creates three-dimensional air circulation patterns rather than traditional two-dimensional flow. This dimensional change allows air to circulate more effectively through the bulk product, improving pasteurization efficiency without significantly increasing device complexity.
2Productivity
If air flow circulation is enhanced to improve pasteurization, then processing effectiveness increases, but energy consumption increases
Solution Approach 1:
The patent optimizes the fan's operational parameters including its angled positioning and rotational speed to achieve maximum air circulation efficiency. By carefully selecting and adjusting these parameters, the system achieves effective pasteurization while minimizing energy consumption, resolving the contradiction between processing effectiveness and energy use.
3Reliability
If air circulation is improved for better pasteurization, then food safety and quality increase, but the processing time may increase
Solution Approach 1:
The angled axial fan creates continuous and uniform air circulation throughout the processing chamber, ensuring consistent heat distribution and uninterrupted pasteurization action. This continuous effective action achieves high reliability pasteurization results without requiring extended processing times, as the optimized air flow pattern eliminates dead zones and ensures all product receives adequate treatment efficiently.
