Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blower devices do not effectively direct air flow towards a person in front of a panel, failing to provide a realistic wind experience and inefficiently manage power consumption based on the presence of individuals.
Innovation Solution
A blower device equipped with cameras for human detection and a control unit that adjusts the rotational speed and direction of fans to blow air towards the person, ensuring a consistent and directed air flow, while also optimizing power usage by stopping operation when no one is present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If air passages are provided in a window frame at both sides of a panel and air is blown out through air holes to cause collision at the center portion, then an air flow toward the front of the panel is generated, but the air flow cannot be effectively directed towards a person in front of the panel
Solution Approach 1:
The patent applies dynamics by making the blowing unit's operation adjustable and responsive to changing conditions. The control unit dynamically controls the blowing operation based on detection results from the human detector, allowing the air flow direction and intensity to adapt to the presence and position of persons in front of the panel.
Solution Approach 2:
The patent implements feedback by using a human detector to sense the presence of persons and feeding this information back to the control unit, which then adjusts the blowing unit's operation accordingly. This closed-loop control enables the system to respond appropriately to user presence and optimize air flow direction.
2Reliability
If the blowing unit operates continuously to provide air flow, then a consistent wind experience is provided, but power consumption increases
Solution Approach 1:
The patent applies periodic action by controlling the blowing unit to operate only when needed - specifically, when a person is detected in front of the panel by the human detector. The control unit activates the blowing unit during detection periods and can deactivate it when no person is present, creating an on-demand operation pattern that reduces unnecessary power consumption while maintaining air flow consistency during active periods.
Solution Approach 2:
The system uses the human detector to automatically determine when operation is needed, making the system self-regulating based on environmental conditions (presence of persons) without requiring manual intervention. The control unit autonomously decides when to activate or deactivate the blowing unit based on detection feedback.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a realistic wind experience by directing air flow towards individuals and conserves power by only operating when people are detected, ensuring efficient energy use and enhanced user interaction.
Implementation Method 1
a fan, air passages, and air holes, the air sent from the fan into the air passages is blown out through the air holes

AI summary
A blower device includes a panel, a frame member disposed to surround the panel, a plurality of fans configured to blow out air through a plurality of blow out ports of the frame member, a control unit configured to control the rotational speed of the fans, and a camera configured to detect presence of a person in front of the panel. The control unit is configured to adjust the flow rate and the flow speed of air blown out through the blow out ports to thereby change the direction of an air flow generated by mutual collision of the blown-out air so that the air is blown out toward the person detected by the camera.
