Solution Overview
Problem
Conventional 4D movie theaters are costly and time-consuming to install, and existing wearable devices for immersive experiences can cause discomfort due to their structural design and special effects.
Innovation Solution
A lightweight and compact wearable device with a sensory unit that provides coolness, warmth, air flow, vibration, and bone conduction sound, designed to be hung around the neck, allowing users to experience immersive multimedia content without discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional 4D movie theaters are constructed, then immersive video viewing experience is provided, but installation cost and time consumption increase significantly
Solution Approach 1:
The patent creates a portable copy of the 4D theater experience through a wearable device that reproduces sensory effects (wind, water, vibration) in a compact form factor. Instead of requiring a full-scale theater construction, the invention copies the essential immersive functions into a wearable format that can be used at home, eliminating the need for complex theater installation while maintaining the core immersive experience
Solution Approach 2:
The patent replaces the complex mechanical infrastructure of traditional 4D theaters (large-scale wind systems, water jets, vibration platforms) with compact electronic components integrated into a wearable device. The mechanical effects are generated through small motors, fans, and pumps housed within the wearable structure, substituting the massive theater-based mechanical systems with portable electronic-mechanical integrations
2Reliability
If headphones, blower device and lamp device are worn in close contact with the user's head, then special effects are enhanced, but hair is pressed down and interferes with hairstyle
Solution Approach 1:
The patent relocates the sensory effects delivery system from the horizontal plane (head-mounted devices pressing on hair) to the vertical dimension (neck-mounted device). By positioning the blower, water spray, and vibration components around the neck area, the invention delivers immersive effects while leaving the user's hair and hairstyle unaffected, as the neck region does not interfere with typical hairstyles
3Reliability
If fan and water tank are equipped for blowing and water effects, then special effects are provided, but significant load is placed on the user's head causing strain on neck and joints
Solution Approach 1:
The patent inverts the mounting location of the sensory effects system from the user's head to the user's neck. By relocating the fan, water tank, and other effect-generating components to a neck-wearable configuration, the weight distribution changes from concentrating load on the head (causing neck and joint strain) to distributing it around the neck circumference, thereby providing the same special effects without the harmful strain on head and joints
4Reliability
If water effect device is operated, then water jets are generated, but users find it unpleasant
Solution Approach 1:
The patent applies water effects locally and selectively rather than as a general overwhelming spray. The water spray is directed specifically at the neck area through controlled nozzles, creating a localized cooling and refreshing sensation that enhances the immersive experience without causing the discomfort associated with full-head water exposure. This localized application allows users to enjoy water effects while avoiding unpleasantness
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 enhances the sense of immersion in watching videos by directly transmitting sensory effects to the user's body, allowing for a more vivid and comfortable 4D-like experience at home.
Implementation Method 1
a coolness and warmth providing unit provided on one side of the main body to provide coolness and warmth to the user's neck
Implementation Method 2
an air supply unit provided on one side of the main body to blow wind toward the user
Implementation Method 3
a touch providing unit provided on one side of the main body to create a tactile sensation on the user's neck
Implementation Method 4
a shock vibration providing unit provided on one side of the main body to provide vibration to the user
Implementation Method 5
a bone conduction vibration sensory providing unit provided on one side of the main body to transmit sound and voice through the user's back in a bone conduction manner
Data Source
AI summary
The present disclosure related to an immersive image experiencing device comprising a main body configured to be hung around a user's neck and a sensory unit configured to be provided on one side of the main body and linked to a display for outputting a video being viewed by the user and to provide a sensory effect for each screen to the user's neck according to a sensory effect code provided for each screen of the video, thereby providing a relatively simple, lightweight, and compact wearable structure to directly transmit the sense of reality of multimedia videos, including movies, to the user's body, thereby enhancing the sense of immersion in watching a video.
