Solution Overview

Problem

Mobile users often become distracted and forget about parked calls, leading to callers being left on hold indefinitely, resulting in wasted time and potential frustration.

Innovation Solution

A telecommunication system that includes a processor configured to send a park reminder message to a remote device after a predetermined time, ensuring that users are alerted to parked calls and can manage them appropriately.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If mobile users park calls to handle multiple tasks, then users can multitask with PDA, email, and text messaging, but callers are left on hold indefinitely and their time is wasted

Engineering Contradiction:

Improveuser multitasking capabilityVSAvoidcaller waiting time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system implements a feedback mechanism by sending automated reminder messages to mobile users about their parked calls after a predetermined time period. This feedback loop alerts users to return to their parked calls, preventing indefinite holding and reducing caller wait time while preserving user multitasking capability.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If mobile users park calls to answer later, then users gain flexibility in call management, but users may become distracted and forget about parked calls

Engineering Contradiction:

Improvecall management flexibilityVSAvoiduser memory of parked call

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system performs preliminary action by sending reminder messages to users before they completely forget about their parked calls. The predetermined time period ensures that users are alerted in advance, maintaining awareness of parked calls while preserving the flexibility to manage calls at convenient times.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If no reminder system is implemented, then the system remains simple, but callers are frequently left on hold indefinitely

Engineering Contradiction:

Improvesystem simplicityVSAvoidcall completion rate

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system implements periodic action through automated reminder messages sent at predetermined time intervals to users with parked calls. This periodic intervention maintains system simplicity while significantly improving call completion rates by preventing users from forgetting about parked calls.

Inventive Principle:

Principle #19Periodic action
