Solution Overview

Problem

Existing air conditioner control systems can inadvertently start an emergency operation while a worker is on-site, posing safety risks.

Innovation Solution

The system includes a control unit that transmits setting information for an emergency operation after instructing to stop all indoor units, ensuring the emergency operation is only initiated when the remote controller of the indoor unit is operated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the emergency operation setting is activated in the air conditioner, then the emergency operation can be started remotely, but the emergency operation may be inadvertently started when a worker is performing operations on-site

Engineering Contradiction:
Improveremote operation capabilityVSAvoidworker safety risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system transmits a stop instruction to all indoor units before transmitting the emergency operation setting. This preliminary action ensures that the air conditioner is in a stopped state before the emergency operation can be activated, preventing inadvertent startup when workers are on-site. The sequence of operations is: receive malfunction report → transmit stop instruction to all indoor units → transmit emergency operation setting → wait for remote controller operation → start emergency operation.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If the emergency operation is started immediately upon receiving malfunction report, then the response time is reduced, but the risk of accidental activation during worker operations increases

Engineering Contradiction:
Improveresponse timeVSAvoidoperation safety
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system performs preliminary stopping of all indoor units before activating emergency operation. This preliminary action sequence (stop instruction first, then emergency operation setting) maintains rapid response by automatically initiating the stop sequence upon malfunction detection, while simultaneously ensuring safety by preventing accidental activation during the transition period.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The remote controller serves as an intermediary device that mediates between the malfunction report and the emergency operation activation. The system requires operation of the remote controller to start the emergency operation, creating an intermediate step that prevents inadvertent activation while maintaining rapid response capability. The remote controller acts as a safety intermediary that confirms intentional activation.

Inventive Principle:
Principle #24Intermediary (Mediator)
