Solution Overview

Problem

Existing motion determination devices for virtual or real spaces require users to hold peripherals and use external sensors, which are complex, skill-intensive, and costly.

Innovation Solution

A device integrated into a shoe with a tilting sole and embedded sensors, including a gyroscope and accelerometer, transmits motion data via Bluetooth or Wi-Fi to a head display unit for virtual reality, allowing motion determination without external peripherals or sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate applications (messaging, email, social media) are used to maintain social connections, then communication coverage is improved, but device complexity and time management burden increase

Engineering Contradiction:
Improvecommunication coverageVSAvoidnumber of applications
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple communication functions (messaging, email, social media updates) into a single unified application interface. Users can send messages, emails, and social media posts through one application, eliminating the need to switch between multiple separate applications and reducing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The application is designed to perform multiple communication functions universally. A single application can handle different types of communications (personal messages, professional emails, social media interactions) through a unified interface, making the system adaptable to various communication needs without requiring multiple specialized applications.

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

2Adaptability or versatility

If users manually manage multiple applications for different communication needs, then communication versatility is improved, but time consumption and ease of operation worsen

Engineering Contradiction:
Improvecommunication versatilityVSAvoidtime to switch applications
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

By merging multiple communication applications into one unified interface, users no longer need to spend time switching between different applications. The single application provides access to all communication functions, eliminating the time loss associated with application switching while maintaining communication versatility.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If conventional motion detection methods are used, then device compatibility is improved, but measurement precision and reliability in virtual environments worsen

Engineering Contradiction:
Improvedevice compatibilityVSAvoidmotion detection accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent introduces a camera as an intermediary device to detect motion in virtual environments. Instead of relying on conventional motion detectors that may not work accurately in virtual spaces, the camera captures visual data that is then processed to determine user motion, providing reliable measurement precision while maintaining compatibility with various devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces conventional mechanical motion detection systems with an optical-based camera system. This substitution allows for accurate motion detection in virtual environments where mechanical sensors may fail, while the processed data can be applied across different device platforms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
