Solution Overview

Problem

Existing communication systems for cordless telephones require additional transmission and reception interfaces, increasing production costs and complexity, and do not allow for seamless call transfer without queuing, especially when using wireless connections like Bluetooth or infrared.

Innovation Solution

A method for simultaneous registration and association of communication devices with a transmitting and receiving station via a DECT interface, where the station processes registration signals to generate association signals, allowing devices to communicate directly without additional interfaces and enabling call takeover without handover confirmation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional transmission and reception interfaces are added to enable direct device-to-device communication, then communication capability is improved, but production costs and manufacturing complexity increase

Engineering Contradiction:
Improvecommunication capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transmitting and receiving station acts as an intermediary between the communication device and the communication device available for association. Instead of requiring direct interfaces between devices, the station mediates the association process by receiving readiness signals, transmitting association signals, and managing the connection state, thereby eliminating the need for additional direct transmission and reception interfaces between devices

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The transmitting and receiving station performs multiple functions: it serves as a communication node, an association manager, and a connection mediator. By consolidating these functions in a single station rather than distributing them across multiple devices, the system avoids the need for additional specialized interfaces on each device, reducing manufacturing complexity while maintaining versatile communication capability

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

2Adaptability or versatility

If call handover is implemented in existing systems, then communication transfer is enabled, but call transfer time increases due to queuing and confirmation requirements

Engineering Contradiction:
Improvecall transfer capabilityVSAvoidcall transfer time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The communication device transmits a readiness for association signal in advance, indicating its availability for call takeover before the actual handover is initiated. This preliminary action allows the transmitting and receiving station to prepare the association process ahead of time, eliminating the need for queuing and confirmation delays during the actual call transfer

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system skips the traditional multi-step handover confirmation process by using a streamlined association mechanism. The readiness signal triggers an automatic association process that bypasses conventional handover delays, allowing the call transfer to occur immediately without the time-consuming confirmation sequences required in existing systems

Inventive Principle:
Principle #21Skipping (Rushing through)
