Solution Overview

Problem

Users of advanced mobile devices with multiple sensors face burdensome selection operations to access desired sensor information, as existing systems require manual selection each time, leading to increased user burden.

Innovation Solution

An electronic device with a processor and memory that receives signals from multiple sensors, determines the user's activity state, selects relevant sensors, and communicates derived information to the user, allowing for automatic selection and notification of desired sensor data without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual selection of sensors is implemented, then users can access desired sensor information, but user burden increases significantly

Engineering Contradiction:

Improveease of accessing sensor informationVSAvoidtime for selection operations

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically determines the user's activity state using sensor data and autonomously selects and displays relevant sensor information without requiring user intervention. The electronic device serves itself by implementing the selection logic internally based on activity recognition, eliminating the need for manual sensor selection by the user.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically changes the displayed sensor information based on detected activity state parameters. When the activity state changes (e.g., from resting to exercising), the system automatically adjusts which sensor data is displayed, ensuring the information shown is relevant to the current activity without requiring user reconfiguration.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple sensors are provided, then comprehensive sensor information is available, but device complexity increases

Engineering Contradiction:

Improvecomprehensiveness of sensor informationVSAvoidcomplexity of sensor management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system extracts and displays only the relevant sensor information needed for the current activity state from the comprehensive set of available sensors. Based on the detected activity (e.g., walking, running, resting), the system selectively presents only the pertinent sensor data, filtering out unnecessary information and simplifying the user interface while maintaining comprehensive sensor capabilities.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system dynamically adjusts which sensor information is displayed based on the detected activity state. The sensor selection and information presentation are not static but change adaptively according to the user's current activity, optimizing the balance between comprehensive data availability and interface simplicity.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If automatic selection is implemented, then user burden is reduced, but system complexity increases

Engineering Contradiction:

Improveease of accessing sensor informationVSAvoidcomplexity of automatic selection system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The activity state determination unit serves multiple functions: it detects the user's activity state, selects relevant sensor information for display, and adapts the information presentation format. By consolidating these functions into a single multi-functional unit, the system reduces overall complexity compared to having separate dedicated components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges the sensor data acquisition, activity state determination, and information selection functions into an integrated processing flow. The activity state determination unit combines multiple sensor inputs and processes them together to determine activity state and simultaneously select the appropriate information to display, reducing the number of separate processing stages.

Inventive Principle:

Principle #5Merging (Combining)
