Operation Terminal Trace Input for Multi-Unit Air Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in setting the air direction for multiple cassette-type indoor units due to the complexity of independently adjusting each vane, making it troublesome to direct airflow to intended positions.
Innovation Solution
An operation terminal with a display screen showing icons corresponding to indoor units and a room layout, allowing users to input traces for airflow settings, which are then translated into commands for setting air direction and volume, simplifying the process through communication with the indoor units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If independent air direction setting for each vane is implemented, then airflow control precision is improved, but operation complexity increases
Solution Approach 1:
The patent combines multiple individual air direction settings into a single macro-setting operation. Users can select multiple indoor units and apply air direction settings to all selected units simultaneously through one operation, rather than configuring each unit separately. This merging approach maintains precise airflow control while dramatically reducing operation complexity.
Solution Approach 2:
The patent introduces universal setting functions that allow users to apply the same air direction configuration to multiple different indoor units at once. The operation terminal provides multi-functional capabilities where a single setting operation can control various types of indoor units (ceiling-mounted, wall-mounted, floor-standing) with different numbers of vanes, making the system universally applicable across diverse HVAC configurations.
2Manufacturing precision
If multiple indoor units are controlled individually, then airflow precision for each unit is improved, but time consumption increases
Solution Approach 1:
The patent implements preliminary selection functionality where users can pre-select multiple indoor units before applying air direction settings. The operation terminal allows users to define a group of target units in advance, and then a single setting operation is applied to all pre-selected units simultaneously. This preliminary action approach maintains precise airflow control for each unit while eliminating the time-consuming sequential configuration process.
Solution Approach 2:
The patent merges multiple individual configuration operations into a single batch operation. By combining the air direction settings for multiple indoor units into one unified operation, the system maintains the precision needed for each unit's specific requirements while reducing the total time consumption from configuring each unit separately to a fraction of that time through simultaneous processing.
3Manufacturing precision
If detailed air direction settings are provided for each unit, then airflow directionality is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complex individual configuration interface and replaces it with a simplified macro-setting interface. The operation terminal separates the detailed air direction parameters from the user interaction layer, allowing users to work with high-level group selections and universal settings. The complex individual unit configurations are extracted and handled automatically by the system based on the user's macro-settings, reducing perceived device complexity while maintaining detailed airflow directionality control.
