Solution Overview

Problem

Conventional low temperature treatment during marine transport of fruits like lemons and grapefruits faces challenges in maintaining a consistent cargo core temperature due to varying heat loads, making it difficult to adhere to quarantine regulations.

Innovation Solution

A set temperature calculating apparatus and system that learns from data correlations between heat load and temperature, adjusting the set temperature dynamically to maintain the cargo core temperature within the required range by using sensors and machine learning to infer and adjust the temperature settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed set temperature is used for low temperature treatment, then the temperature control system is simple to operate, but the cargo core temperature cannot be maintained within the required range due to varying heat loads

Engineering Contradiction:
Improvetemperature control reliabilityVSAvoidtemperature control system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transitioning from a fixed set temperature to a dynamic set temperature that automatically adjusts based on real-time heat load conditions. The system continuously monitors heat load parameters (ambient temperature, humidity, ventilation) and dynamically recalculates the set temperature using a learned model, ensuring the cargo core temperature remains within the required range despite varying external conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by using the learned model to predict the relationship between heat load and cargo core temperature, then using this prediction to automatically adjust the set temperature. The system continuously feeds back temperature deviation information and heat load changes to the control algorithm, enabling closed-loop control that maintains temperature reliability without manual intervention.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the set temperature is manually adjusted according to heat load changes, then the temperature control is simple, but it is impossible to realize proper temperature control because heat load changes greatly during marine transport

Engineering Contradiction:
Improvetemperature adjustment easeVSAvoidlow temperature treatment compliance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies self-service by enabling the temperature control system to automatically adjust the set temperature without manual intervention. The learned model autonomously processes heat load data and calculates appropriate set temperature adjustments, making the system self-regulating and eliminating the need for operators to manually respond to heat load changes during marine transport.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical temperature adjustment with an automated intelligent control system. Instead of operators manually changing temperature settings based on observations, the system uses a learned model (machine learning algorithm) to automatically calculate and apply set temperature adjustments, substituting human judgment with an automated decision-making system that responds instantly to heat load changes.

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

3Reliability

If a learned model is used to dynamically adjust set temperature, then the cargo core temperature is maintained within the required range, but the system complexity increases

Engineering Contradiction:
Improvecargo core temperature maintenanceVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-training the learned model with historical data before actual temperature control operations. The model learns the complex relationship between heat load parameters and cargo core temperature in advance, storing this knowledge for rapid deployment during marine transport. This preliminary learning phase separates the complex computational work from the real-time control operation, reducing the apparent system complexity during actual use.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by having the learned model process multiple heat load parameters (ambient temperature, humidity, ventilation volume) and transform them into an optimized set temperature parameter. The model dynamically adjusts the set temperature based on the combined influence of these parameters, converting complex multi-parameter input into a single actionable control parameter that maintains cargo core temperature reliability.

Inventive Principle:
Principle #35Parameter changes
