Solution Overview

Problem

Existing transportation machines with multiple compartments for temperature-controlled storage consume significant energy, which is undesirable from an energy consumption perspective.

Innovation Solution

A control device and method that includes a processor to move articles between compartments based on predetermined conditions, such as temperature management needs and recipient availability, and control temperature in compartments that can be adjusted, optimizing energy use by minimizing unnecessary temperature control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If temperature control is continuously performed in all compartments, then article quality is maintained, but energy consumption increases significantly

Engineering Contradiction:
Improvearticle qualityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system applies temperature control selectively to specific compartments based on their actual needs rather than uniformly to all compartments. The control device determines which compartments require temperature management by checking if they contain articles requiring temperature control, and only activates temperature control for those specific compartments, thereby reducing overall energy consumption while maintaining article quality where necessary

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts temperature control activation based on real-time conditions. The control device continuously monitors compartment contents and temperature control requirements, activating or deactivating temperature control in each compartment as needed. This dynamic approach ensures temperature control is applied only when and where articles require it, optimizing the balance between article quality maintenance and energy consumption

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If articles are moved between compartments based on temperature needs, then energy efficiency improves, but system complexity increases

Engineering Contradiction:
Improveenergy efficiencyVSAvoidsystem complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The control device performs multiple functions: it monitors article information, determines temperature control requirements, manages temperature control activation, and controls article movement between compartments. By consolidating these diverse functions into a single control device, the system achieves energy efficiency through intelligent article relocation while minimizing the increase in system complexity through functional integration

Inventive Principle:
Principle #6Universality (Multi-functionality)
