Indoor Unit Flap Marking for Outlet Identification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In indoor air conditioning units with multiple flaps at outlets, users face difficulty in identifying which flap to control, especially when the remote control is distant from the unit, making it hard to recognize the intended flap for wind direction changes.
Innovation Solution
The indoor unit incorporates distinct sign sections, such as raised or recessed portions, printed characters, or stickers on the outlets and flaps, allowing easy identification of each outlet and flap, with the option of light-emitting sections for enhanced visibility, and a controller for managing flap positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If flaps are made substantially the same shape to simplify manufacturing, then manufacturing complexity is reduced, but ease of operation deteriorates because users cannot easily identify which flap to control
Solution Approach 1:
The patent applies local quality by adding distinctive sign sections (different shapes, sizes, or patterns) to specific flaps while keeping the overall flap structure uniform. This allows users to easily identify which flap to control without requiring different flap shapes, thus maintaining manufacturing simplicity while improving operability.
Solution Approach 2:
The patent uses visual differentiation through sign sections on flaps, analogous to color changes, to provide distinctive identification marks. These signs enable users to recognize and select the intended flap for control from a distance, solving the identification problem without complicating the manufacturing process.
2Ease of operation
If remote control is placed at a corner distant from the indoor unit to provide user convenience, then ease of operation is improved, but ease of detection deteriorates because users cannot check flap movement while operating
Solution Approach 1:
The patent places distinctive sign sections on or near the flaps, creating localized visual markers that are easily detectable from a distance. This allows users to confirm flap movement and position even when the remote control is positioned far from the indoor unit, thus resolving the detection difficulty while maintaining operational convenience.
Solution Approach 2:
The sign sections act as visual intermediaries between the user and the flap mechanism. These markers provide feedback about flap position and movement without requiring the user to be physically close to the unit, enabling remote operation with visual confirmation.
3Ease of operation
If multiple flap shapes are used to differentiate outlets and flaps, then ease of operation is improved for identification, but device complexity increases
Solution Approach 1:
The patent maintains uniform flap shapes for all outlets but adds distinctive sign sections to specific flaps or their corresponding outlet regions. This approach provides clear visual identification for users while avoiding the complexity of manufacturing and assembling multiple types of flaps with different shapes.
Solution Approach 2:
The patent segments the identification function from the flap structure itself, placing distinctive signs on the flaps or near the outlets rather than making the flaps themselves different shapes. This segmentation allows identification without increasing structural complexity.

AI summary
An indoor unit and an air conditioner configured so that each outlet and each flap can be easily identified. An indoor unit (1) is provided with outlets (32a-32d) which discharge air-conditioning air toward the interior space, and also with flaps (35a-35d) having substantially the same shape, the flaps (35a-35d) being respectively disposed at the outlets (32a-32d) and capable of individually changing the discharge directions of the air-conditioning air. Sign sections (60a-60d) which are different from each other are formed either in the vicinities, respectively, of the outlets (32a-32d) or on the flaps (35a-35d), respectively.
