Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable devices for virtual reality (VR) systems are often bulky and complex, detracting from the user experience due to their circuitry, which can be heavy and cumbersome, limiting the immersion and interaction within virtual environments.
Innovation Solution
The use of fluidic devices, which function analogously to electronic components, are integrated into wearable devices to provide haptic feedback and control actuators, allowing for a more compact and efficient means of interacting with virtual objects by using channels with gates that regulate fluid flow based on pressure, enabling the creation of composite fluidic devices for haptic apparatuses.

Engineering Contradiction Analysis
1Ease of operation
If conventional electronic devices with circuitry are used in wearable devices for VR systems, then functional control and haptic feedback can be achieved, but the devices become bulky, heavy, and complex
Solution Approach 1:
The patent replaces electronic circuitry with a fluidic system that uses fluid pressure and flow to perform logical operations and control functions. Fluidic devices such as fluidic transistors, logic gates, and decoders manipulate fluid flow through channels and gates to achieve the same control functions as electronic circuits, thereby eliminating complex electronics from the wearable device.
Solution Approach 2:
The patent employs pneumatic and hydraulic principles by using compressed gas or liquid to power actuators and control mechanisms. The fluidic control system uses pressure differentials and fluid flow to actuate components, providing a mechanical alternative to electronic control systems in wearable VR devices.

Function Achieved in This Case
This solution enables a more immersive and interactive VR experience by reducing the bulk and complexity of wearable devices, allowing for precise haptic feedback and control, thereby enhancing user engagement and interaction within virtual environments.
Implementation Method 1
The gate includes a chamber with an adjustable volume that affects fluid flow within the channel by displacing a first wall of the channel toward a second wall of the channel that is opposite the first wall. The displacement is based on fluid pressure within the chamber exceeding a threshold pressure.
Data Source
AI summary
A fluidic device comprises a channel, a gate, and one or more additional elements. The channel is configured to transport a fluid from a source to a drain. The gate includes a chamber with an adjustable volume that affects fluid flow within the channel by displacing a wall of the channel toward an opposite wall of the channel based in part on fluid pressure within the chamber exceeding a threshold pressure. A high pressure state of the gate corresponds to a first chamber size and a first flow rate of the fluid. A low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size and a second flow rate that is greater than the first flow rate. The additional elements are configured to reduce the threshold pressure past which the chamber decreases the cross-sectional area of the channel.
