Solution Overview

Problem

Current interactive game systems, despite advancements in computer technology, fail to provide a deeply immersive experience akin to reality, as they are limited to two-dimensional interactions and lack the realism offered by three-dimensional graphics.

Innovation Solution

An interactive game system comprising a head-mounted device, a game suit with wireless sensors, and a ground pad with wireless charging devices, which together enable virtual reality experiences by providing power to the game suit and detecting user movement to enhance interaction and immersion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless sensors and battery are integrated into the game suit for immersive VR interaction, then user mobility and interaction quality are improved, but the device requires frequent charging which interrupts gameplay

Engineering Contradiction:
Improveuser mobilityVSAvoidcharging interruption
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The ground pad performs preliminary charging actions by detecting user approach through wireless sensors and automatically initiating power transfer before the battery is depleted, ensuring continuous operation without interrupting gameplay

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements self-service charging where the ground pad autonomously detects user presence, determines charging needs based on battery status, and initiates wireless charging without requiring user intervention, maintaining immersive gameplay continuity

Inventive Principle:
Principle #25Self-service

2Reliability

If multiple wireless charging devices are arranged in a matrix on the ground pad to provide continuous power, then power availability is improved, but system complexity increases

Engineering Contradiction:
Improvepower availabilityVSAvoidcharging system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The ground pad is segmented into multiple independent wireless charging devices arranged in a matrix, with each device capable of autonomous detection and charging operations, distributing the reliability function across multiple simple units rather than one complex system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each wireless charging device in the matrix serves multiple functions: detecting user approach, determining charging needs, and executing power transfer, allowing any device in the matrix to serve the user based on position and need, simplifying individual device design while maintaining system reliability

Inventive Principle:
Principle #6Universality (Multi-functionality)

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 system offers a more immersive and realistic virtual reality experience by allowing users to interact with three-dimensional virtual environments, enhancing user engagement and immersion through the integration of wireless charging and sensor technology.

Implementation Method 1

The ground pad comprises a plurality of wireless charging devices that are arranged in a matrix and connected to a power outlet to provide power, wherein when the wireless charging device detects an approaching wireless sensor, the position information of the wireless charging device is transmitted to the wireless sensor and a signal indicating whether the battery needs to be charged is transmitted to the wireless charging device; wherein if the battery needs to be charged, the wireless charging device charges the battery via the wireless sensor.

AI summary

An interactive game system is provided. The interactive game system includes a head-mounted device (HMD), a game suit, a battery and a ground pad. The HMD executes a virtual reality program and displays video information of the virtual reality program to a user. The game suit is worn by the user and connected to the HMD. The game suit includes wireless sensors. The battery provides power to the HMD. The ground pad includes wireless charging devices arranged in a matrix to provide power. When the wireless charging device detects an approaching wireless sensor, the position information of the wireless charging device is transmitted to the approaching wireless sensor and a signal indicating whether the battery needs to be charged is transmitted to the wireless charging device. If the battery needs to be charged, the wireless charging device charges the battery via the approaching wireless sensor.
