Solution Overview

Problem

Public safety personnel face challenges in navigating and accessing the appropriate software applications when switching between multiple talkgroups, as each talkgroup may require different applications based on the roles of its participants.

Innovation Solution

A communication device with a graphical user interface that allows users to easily transition between talkgroups by generating screens with relevant applications for each talkgroup, including applications related to incidents associated with those talkgroups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If users manually navigate through multiple screens to access applications in different talkgroups, then application access is possible, but navigation time and operational complexity increase

Engineering Contradiction:
Improvenavigation timeVSAvoidoperational complexity
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The system pre-organizes applications into talkgroup-specific groups and prepares the navigation structure in advance. When a user switches talkgroups, the already-prepared application groups are immediately presented, eliminating the need for manual searching or multi-screen navigation during the switch.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments applications into distinct groups based on their association with specific talkgroups. This segmentation allows the system to present only the relevant application group for the current talkgroup, reducing navigation complexity and time by eliminating unrelated applications from the user's view.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the system presents all available applications regardless of talkgroup, then application availability is maximized, but interface complexity and user confusion increase

Engineering Contradiction:
Improveapplication availabilityVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system applies local quality by customizing the application display based on the current talkgroup context. Each talkgroup receives a tailored view showing only the applications relevant to that specific talkgroup, while maintaining access to all applications through the talkgroup association mechanism. This reduces interface complexity while preserving full application availability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements a universal application group structure where each application group can serve multiple talkgroups. An application group defined for one talkgroup can be automatically associated with other talkgroups, allowing the same application set to be universally applied across multiple contexts without increasing interface complexity.

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

3Productivity

If the system automatically switches applications when changing talkgroups, then navigation efficiency improves, but user control and customization options decrease

Engineering Contradiction:
Improvenavigation efficiencyVSAvoiduser control
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system implements dynamic behavior where application switching during talkgroup changes can be automatically triggered based on system rules, but users retain the ability to manually select from alternative application groups if desired. This dynamic approach adapts to user needs while maintaining efficiency, allowing automatic switching when appropriate but preserving user control when customization is needed.

Inventive Principle:
Principle #15Dynamics

AI summary

A method (300A) and device (102) for navigating between multiple talkgroups. The device (102) includes a user input interface, a display (218), and an electronic processor (205) communicatively coupled to the display (218). The processor (205) is configured to generate, on the display (218), a graphical user interface, associate the communication device (102) with a first talkgroup (110A), present, on the display (218), a first application related to the first talkgroup (110A), receive, via the user input interface, a user input indicative of a request to change talkgroups, associate, in response to the user input, the communication device (102) with a second talkgroup (110B), and present, on the display (218), a second application related to the second talkgroup (110B).
