Solution Overview

Problem

Existing communication systems for offices and contact centers using wireless headsets and cordless telephones often lack seamless integration and advanced user interfaces, limiting functionality and interoperability between headset and telephone base units.

Innovation Solution

A communication system where the headset base transceiver and telephone base transceiver are connected by a third radio link following the DECT standard, allowing the headset to be used for calls and utilizing advanced features like touch-screen displays and GAP compatibility for easy part exchange and configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the headset base station functions only as a charger with direct headset-to-telephone communication, then the device complexity is reduced, but the adaptability and advanced user interface features are limited

Engineering Contradiction:
Improveheadset base functionalityVSAvoidsystem configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The headset base station is designed to perform multiple functions: it serves as a charging cradle for the headset, acts as a DECT slave device to communicate with the telephone base station, and provides advanced user interface features through its own display and controls. This multi-functional design allows the headset base to be more than just a simple charger, enabling features like call management, contact display, and settings adjustment without requiring the headset to directly connect to the telephone base.

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

Solution Approach 2:

The headset base station acts as an intermediary device between the headset and the telephone base station. It receives DECT signals from the telephone base (including call information, contact data, and control commands) and relays them to the headset, while also providing its own user interface capabilities. This intermediary role allows the system to maintain advanced functionality without requiring direct headset-to-telephone communication, thus resolving the contradiction between versatility and complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the headset transceiver communicates directly with the telephone base transceiver, then the connection is simple, but the advanced user interface features and status information indicators are lost

Engineering Contradiction:
Improveconnection simplicityVSAvoidstatus information and interface features
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system is segmented into three functional components: the headset with its transceiver, the headset base station with its own transceiver and user interface, and the telephone base station. This segmentation allows the headset base to serve as an independent intermediary that maintains communication with both the headset and the telephone base, preserving advanced interface features while keeping the overall connection architecture relatively simple through standardized DECT protocols.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If extra handsets are provided with charging cradles only, then the device complexity is reduced, but the interoperability and advanced features are limited

Engineering Contradiction:
Improvehandset configurationVSAvoidsystem interoperability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The headset base station is designed as a universal device that can function as a charging cradle for headsets while also serving as a DECT slave device that communicates with the telephone base station. This universal design allows the same device to provide both simple charging functionality and advanced communication features, enabling extra headsets to have access to full system features without requiring complex configurations or additional components.

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