Solution Overview

Problem

Existing remote control devices for air-conditioning apparatuses do not allow users to check the operating state of the apparatus before activating a function, requiring users to look at the apparatus itself, which decreases convenience.

Innovation Solution

A remote control device with a display unit showing the operating state and a touch panel that allows users to operate custom buttons assigned with specific functions while viewing the state, enabling function activation without needing to check the apparatus directly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If functions are assigned to custom buttons in accordance with user request, then operability in selecting a function is improved, but the user cannot check the operating state of the apparatus before activating the function

Engineering Contradiction:
Improveoperability in selecting a functionVSAvoidinformation about operating state
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent combines the custom button for function activation with the display of operating state information into a single integrated interface element. When the user touches the custom button area on the display, it simultaneously shows the operating state (such as whether the air conditioner is running, temperature settings, or mode) and allows function activation, merging information display and control functions into one interaction point.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display screen acts as an intermediary between the user and the apparatus state. Instead of requiring direct visual inspection of the apparatus or separate display elements, the touch display mediates by showing operating state information in response to user interaction with the custom button, providing indirect but sufficient information about the apparatus condition.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the user needs to look at the main body of the apparatus to check the operating state, then accurate state information is obtained, but convenience is decreased

Engineering Contradiction:
Improveaccuracy of state informationVSAvoidconvenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent creates a visual copy or representation of the apparatus operating state directly on the remote control's display screen. Instead of requiring the user to view the actual apparatus, the display shows a replicated view of the operating state (temperature, mode, runtime status) that accurately reflects the apparatus condition, allowing verification without physical inspection.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If multiple functions are available on the remote control, then versatility is improved, but the complexity of selecting functions increases

Engineering Contradiction:
Improvenumber of available functionsVSAvoidcomplexity of selecting functions
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by making the custom button's function and appearance context-dependent on the displayed operating state. The button's label, icon, or visual characteristics change based on the current apparatus state (e.g., showing different information for cooling vs. heating mode), allowing the interface to adapt its local properties to the global system state and reduce selection complexity.

Inventive Principle:
Principle #3Local quality
