Solution Overview

Problem

Refrigerating apparatuses often fail to set suitable temperature conditions without technical knowledge, leading to improper refrigeration and deterioration of objects, even when data is inputted correctly.

Innovation Solution

A refrigerating apparatus control circuit and method that stores specific data for various objects, allowing users to select the object to be refrigerated, which automatically sets appropriate temperature zones, including chilled, frozen, and transportation-specific settings, using a control circuit with a refrigerating driving control section, control constant storage, display, and operation sections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users input temperature settings manually into the control panel, then the refrigerating apparatus can operate, but the temperature settings may be inappropriate without technical knowledge about the object being refrigerated

Engineering Contradiction:
Improveease of temperature settingVSAvoidappropriateness of refrigeration conditions
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system automatically retrieves and applies appropriate temperature settings based on the refrigerated object type without requiring user expertise. The control unit autonomously selects optimal parameters from stored data corresponding to the selected object, making the system self-sufficient in providing correct refrigeration conditions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A database or storage unit acts as an intermediary between the user selection and the control parameters. This intermediary contains pre-stored optimal temperature settings for various objects, translating simple object selection into appropriate technical parameters without requiring direct user knowledge of refrigeration science.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If detailed refrigeration knowledge is required to set proper temperatures, then accurate refrigeration can be achieved, but users without technical knowledge cannot properly operate the apparatus

Engineering Contradiction:
Improveaccuracy of refrigeration settingsVSAvoiduser accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system stores copied optimal setting data from expert knowledge sources into an accessible database. Instead of requiring users to possess expert knowledge, the system has pre-captured and stored the correct temperature settings for various objects, making expert-level parameters available to ordinary users through simple selection interfaces.

Inventive Principle:
Principle #26Copying

3Productivity

If wrong refrigeration conditions are applied, then the apparatus may operate, but the quality of the refrigerated object will deteriorate

Engineering Contradiction:
Improveoperational capabilityVSAvoidquality deterioration of refrigerated object
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system provides feedback mechanisms that monitor refrigeration conditions and object state to ensure appropriate settings are applied. By linking object selection to pre-determined optimal parameters and monitoring the refrigeration process, the system prevents harmful conditions that would lead to quality deterioration while maintaining productive operation.

Inventive Principle:
Principle #23Feedback

AI summary

According to the present invention, a user specifies an object (4) to be refrigerated, and a refrigerating apparatus (3) is driven under refrigerating conditions corresponding to the object (4). A refrigerating driving control section (11) controls the driving of the refrigerating apparatus (3). A control constant storage section (12) stores data in which information indicating the object (4) to be refrigerated by the refrigerating apparatus (3) and control constants that the refrigerating driving control section (11) adopts for the object (4) are associated together. An operation of operation section (14) specifies the object (4). From the control constant storage section (12), the refrigerating driving control section (11) reads the control constants corresponding to the object (4) specified by the operation section (14), and the driving of the refrigerating apparatus (3) is controlled on the basis of the read control constants.
