Solution Overview

Problem

Existing particles object freezing devices suffer from uneven freezing rates leading to deteriorated appearance quality due to varying movement rates of particles objects on conveyor belts, causing coagulation and surface adhesion issues.

Innovation Solution

The device employs an air-permeable belt with an injection plate featuring first and second injection parts with different opening ratios disposed along the width direction of the belt, promoting uniform fluidization and movement of particles objects to prevent coagulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple regions with different opening ratios are arranged only in the conveying direction, then freezing rate is improved, but appearance quality deteriorates due to dominant active movement of particles with different freezing rates

Engineering Contradiction:
Improvefreezing rateVSAvoidappearance quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent transitions from arranging injection parts only in the conveying direction (one dimension) to arranging them in both the conveying direction and width direction (two dimensions). This dimensional expansion allows particles to move actively in multiple directions, preventing dominant movement patterns that cause adhesion while maintaining effective freezing rates across different particle types.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The injection plate is divided into multiple injection parts with different opening ratios arranged in both conveying and width directions. Each local region provides tailored gas flow characteristics, creating a distributed pattern of active movement throughout the particle bed. This local variation in injection characteristics prevents uniform dominant movement patterns that lead to adhesion, while collectively maintaining high freezing efficiency.

Inventive Principle:
Principle #3Local quality

2Productivity

If particles objects move actively with different rates, then freezing efficiency is improved, but surface adhesion and coagulation occur leading to poor appearance quality

Engineering Contradiction:
Improvefreezing efficiencyVSAvoidsurface adhesion and coagulation
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

By arranging injection parts with different opening ratios in both conveying and width directions, the system creates multi-directional active movement patterns. This prevents particles from following单一运动路径 that would cause them to converge and adhere to each other, thereby eliminating coagulation while preserving freezing efficiency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The injection plate employs asymmetric distribution of opening ratios in different regions arranged in both directions. This asymmetric gas flow pattern creates varied movement trajectories for different particles, preventing symmetric convergence and adhesion patterns. The asymmetric design ensures particles disperse rather than coagulate while maintaining active movement for efficient freezing.

Inventive Principle:
Principle #4Asymmetry
