Solution Overview

Problem

The construction system for heat pump devices is transported from the factory with the front surface grill detached, reducing the risk of damage and construction steps, but requires confirmation of grill attachment before operation to prevent exposure of the air-blowing fan.

Innovation Solution

A construction system with a display, input section, and controller that prompts various settings before operation, including a confirmation display to ensure the front surface grill is attached to the outdoor unit body, preventing operation if the grill is not attached.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the front surface grill is detached during transportation, then the risk of damage and construction steps are reduced, but the air-blowing fan becomes exposed during operation

Engineering Contradiction:
Improvedamage risk to front surface grillVSAvoidprotection of air-blowing fan
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The system performs preliminary verification by displaying a confirmation screen before operation that asks whether the front surface grill is attached. This preliminary action prevents the harmful effect of fan exposure by ensuring the grill is properly installed before the air-blowing fan operates, thus resolving the contradiction between transportation convenience and operational safety.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the front surface grill is attached during transportation, then the air-blowing fan is protected, but the front surface grill may be damaged and construction steps increase

Engineering Contradiction:
Improveprotection of air-blowing fanVSAvoiddamage risk to front surface grill
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The confirmation display is shown as a preliminary action before operation, allowing contractors to verify grill attachment status without requiring the grill to be permanently fixed during transportation. This resolves the contradiction by providing safety verification at the appropriate time (before operation) rather than forcing attachment during transportation.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If operation is allowed without grill attachment confirmation, then construction steps are simplified, but the air-blowing fan may operate exposed causing harmful effects

Engineering Contradiction:
Improveconstruction process simplicityVSAvoidharmful effects from exposed air-blowing fan
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The system implements feedback by displaying a confirmation screen that requires contractor input regarding grill attachment status. This feedback mechanism ensures that the harmful effect of fan exposure is prevented while maintaining ease of operation, as the confirmation process is simple and does not add significant construction steps.

Inventive Principle:
Principle #23Feedback
