Wind Presentation Diaphragm for Instantaneous Air Blast Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content presentation systems face challenges in providing instantaneous and responsive air blasts for simulating realistic sensations, such as explosions, due to the time required for fans to reach desired resolutions, noise issues with small diameter fans, and difficulty in arbitrarily changing wind intensity or frequency.
Innovation Solution
A content presentation system featuring a wind presenting device with a housing, diaphragm, and diaphragm drive mechanism that generates air blasts by reducing the volume of the housing and diaphragm space, using propellers to guide air flow, and a signal generating unit that creates drive signals based on content triggers, allowing for instantaneous and controlled air blasts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a fan is used to generate air blasts, then air can be presented to the user, but it takes time for the fan to reach the desired number of revolutions, reducing responsiveness
Solution Approach 1:
The system pre-charges a chamber with air before a trigger event occurs. When the trigger is activated, the pre-charged air is immediately released through a nozzle to create an instantaneous air blast, eliminating the startup delay associated with fan acceleration.
Solution Approach 2:
The invention uses a pneumatic chamber that can be rapidly pressurized and then releases air through a controlled opening. This pneumatic mechanism enables much faster response times compared to mechanical fans, as gas pressure can be built and released almost instantaneously.
2Speed
If a small diameter fan is used to improve responsiveness, then the fan can accelerate faster, but noise increases
Solution Approach 1:
The system replaces the small, noisy fan with a pneumatic chamber that stores pressurized air. The air release mechanism produces the air blast without the continuous mechanical rotation and associated noise of a small fan, achieving responsiveness without the harmful noise factor.
3Adaptability or versatility
If a fan is used to generate air blasts, then air can be presented, but it is difficult to arbitrarily change wind intensity or frequency
Solution Approach 1:
The system uses a solenoid valve that can be dynamically controlled to adjust the opening degree and duration of air release. By varying the valve control parameters, the system can flexibly adjust wind intensity and frequency without requiring complex mechanical adjustments to the fan itself.
Solution Approach 2:
The invention changes the control parameter from fan speed regulation to valve opening degree and timing control. This parameter transformation simplifies the control mechanism while enabling arbitrary adjustment of wind intensity and frequency through electronic control of the solenoid valve.

Implementation Method 1
a diaphragm drive mechanism that drives the diaphragm, reduces a volume of a space formed by the housing and the diaphragm, and causes air in the space to blast from the opening
Implementation Method 2
Two propellers with a common shaft further guide the flow of air from first to second opening
