Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The remote control unit for air conditioning apparatuses becomes increasingly complex and difficult to use as functions are added, despite efforts to reduce the number of switches and improve operability.
Innovation Solution
A remote control unit with a display unit, cursor-moving means, and confirmation means, where the controller allows users to select display modes and manage items more efficiently by varying screen outputs and displaying modes based on user needs, enabling easier operation and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functions are added to the remote control unit, then the functionality and versatility are improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent applies multi-functionality by enabling a single switch to perform multiple functions through software control. The controller executes different operations based on pressing patterns (single press, double press, long press) and contextual states, allowing one physical switch to replace multiple dedicated switches. This resolves the contradiction by maintaining versatility while reducing device complexity.
Solution Approach 2:
The patent implements dynamics by making the switch functions adaptive and changeable through software. The controller dynamically assigns different functions to switches based on operational context, pressing patterns, and system state. This allows the remote control to adapt its functionality without adding physical switches, resolving the contradiction between versatility and complexity.
2Ease of operation
If the number of switches is reduced to simplify operation, then the ease of operation is improved, but the adaptability and functionality deteriorate
Solution Approach 1:
The patent enables switches to perform multiple functions through software-based function assignment. A single switch can execute different operations depending on pressing patterns (single press for one function, double press for another, long press for a third) and contextual conditions. This maintains full functionality while reducing the physical number of switches, thereby improving ease of operation.
Solution Approach 2:
The patent changes the operational parameters of switches by introducing varied pressing patterns (duration, frequency, sequence) to differentiate functions. Instead of requiring separate switches for each function, the system uses parameter variations in switch presses to activate different functions, maintaining functionality while simplifying the physical interface.
3Ease of operation
If multiple display modes are provided to improve usability, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements multiple display modes that can be dynamically switched based on operational context and user preferences. The display unit adapts its presentation format (detailed view, simplified view, icon-based view) through software control without adding physical display components. This resolves the contradiction by providing usability benefits while avoiding additional hardware complexity.

AI summary
A remote control unit of an air conditioning apparatus includes a display unit, a cursor-moving member, a confirmation member, and a controller. The display unit displays a menu and a cursor that indicates an item among a plurality of items inside the menu and is moved by the cursor-moving member when operated by a user. The confirmation member is configured to decide that the item is to be executed. The controller controls the display unit in response to the cursor-moving member or confirmation member being operated, and stores screen display modes displayed on the display unit. Upon receiving a predetermined input from the confirmation member, the controller causes items allowing selection of the display modes to be displayed on the menu.
