Solution Overview

Problem

Existing mobile device positioning technologies lack precision and convenience in determining the position of a mobile device relative to a user, especially when the device transitions from a known to an unknown position, such as from being held to being placed in a pocket.

Innovation Solution

A method and apparatus that determine the position of a mobile device by acquiring position difference information using sensors like acceleration and gyroscope, comparing it to a known first position, and calculating the new position, allowing for precise positioning and adjustment of function states based on the device's location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional positioning methods are used to determine mobile device position relative to user body, then the positioning can be achieved, but the positioning precision is insufficient and the convenience is poor

Engineering Contradiction:

Solution Approach 1:

The patent replaces traditional mechanical positioning methods with sensor-based detection systems. Acceleration sensors, gyroscopes, and other sensing devices are used to detect device state changes and calculate position differences, achieving precise positioning without complex mechanical structures or manual operations.

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

Solution Approach 2:

The mobile device automatically detects its own position changes using built-in sensors. The device self-monitors acceleration, orientation, and state transitions, then autonomously calculates position differences and determines new positions without requiring external positioning equipment or user intervention.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If sensors like acceleration and gyroscope are used to acquire position difference information, then the positioning precision is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent makes existing mobile device sensors serve multiple functions. The acceleration sensor and gyroscope, originally designed for other purposes, are utilized for position determination. This approach achieves precise positioning measurements without adding dedicated positioning hardware, thereby avoiding increased device complexity.

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

Solution Approach 2:

The mobile device utilizes its own built-in sensors for position determination rather than requiring external positioning systems. The device's existing sensing capabilities are leveraged to detect state changes and calculate position differences, eliminating the need for additional positioning equipment.

Inventive Principle:
Principle #25Self-service
