Solution Overview

Problem

Cellular phone ring tones often disrupt quiet or formal environments due to users' failure to silence them appropriately, as they may not be aware of the context or forget to reconfigure their phones when circumstances change.

Innovation Solution

A method using network entities like access points to detect cellular phones entering specific space time zones and send recommendations to adjust their configuration settings, such as silencing ring tones, based on the zone's characteristics, promoting appropriate alert settings through visual, audible, or tactile means.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If users manually suppress ring tones by pressing buttons or configuring settings, then ring tone disturbances are reduced, but users may forget to do so or be unaware of inappropriate environments

Engineering Contradiction:
Improvering tone disturbanceVSAvoiduser awareness of environment
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The system provides automatic feedback to the user about the current environment's appropriateness for ring tones. The access point detects the user's location and sends notifications indicating whether the environment is appropriate or inappropriate for audible ring tones, eliminating the need for users to manually remember or assess environmental context.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs automatic environmental assessment and configuration recommendations without requiring user intervention. The access point autonomously detects space-time zones, determines appropriateness, and provides guidance to users, allowing the system to serve itself in monitoring and managing ring tone appropriateness.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If users reconfigure phones frequently to match changing environments, then situational appropriateness is maintained, but user convenience decreases

Engineering Contradiction:
Improvering tone appropriatenessVSAvoidphone configuration convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system provides advance notice to users about upcoming environmental changes that may affect ring tone appropriateness. By notifying users before they enter inappropriate zones or before circumstances change, the system allows users to proactively adjust settings rather than reacting to problems after they occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors user location and environment characteristics, providing real-time feedback about whether current ring tone settings are appropriate. This automatic feedback loop eliminates the need for users to manually reconfigure phones, as the system informs them when configuration changes would be beneficial.

Inventive Principle:
Principle #23Feedback

3Loss of information

If the system automatically detects phones and sends configuration recommendations, then user awareness and appropriate use improve, but network complexity increases

Engineering Contradiction:
Improveuser awareness of contextVSAvoidnetwork entity functionality
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The access point leverages its existing multi-functionality in the wireless network infrastructure to also perform space-time zone detection and ring tone appropriateness assessment. By utilizing the access point's existing capability to detect user presence and location, the system adds environmental monitoring functionality without requiring entirely new dedicated devices.

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