Solution Overview

Problem

Users of short-range wireless communication devices face uncertainty when interacting with nearby devices, as they cannot reliably verify which device is intended for communication, leading to potential mistakes or confusion.

Innovation Solution

A communication device with a processing unit and user interface that receives a short-range wireless communication signal, reads the communication identifier, determines specific audio/visual media content, and prompts the user for verification before performing an action, ensuring controlled interactions with the correct device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automatic action is performed upon receiving short-range wireless communication signal, then productivity is improved, but reliability deteriorates due to user uncertainty about which device is being interacted with

Engineering Contradiction:

Improvespeed of action executionVSAvoidaccuracy of device identification

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary verification by presenting distinctive media content (visual, auditory, or audiovisual) that represents the target device before executing the action. This allows the user to confirm device identity in advance, resolving the contradiction between fast automatic execution and reliable device identification.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Distinctive media content serves as an intermediary between the received communication signal and the action execution. The media content (displayed on screen or played through speaker) acts as a recognizable representation of the target device, allowing users to verify device identity without directly interacting with the technical signal.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If verification step is added to confirm device identity, then reliability is improved, but loss of time increases due to additional user interaction required

Engineering Contradiction:

Improveconfidence in correct device interactionVSAvoidduration from signal reception to action execution

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system presents only essential distinctive media content that is sufficient for user verification without requiring complex interaction sequences. The verification is partial (just enough to identify the device) rather than excessive, minimizing time loss while maintaining reliability.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent replaces complex mechanical verification systems (multiple buttons, menus, confirmation dialogs) with sensory-based verification using distinctive media content. Users can quickly recognize their target device through visual display or auditory output, reducing verification time compared to traditional multi-step confirmation processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A communication device (100; 100a) has a processing device (110), a user interface (120), and a short-range wireless communication transceiver (130). The short- range wireless communication transceiver (130) is configured for receiving a short- range wireless communication signal (S) from another communication device (100b). The processing device (110) is configured for reading a communication identifier (CI) of the received short-range wireless communication signal (S), determining - based on the communication identifier (CI) - a particular audio/visual/audiovisual media content (140a) among a plurality of possible media contents (140), controlling the user interface (120) to present the particular media content (140a) to a user (1a) of the communication device (100; 100a), and controlling the user interface (120) to receive an input (INP) from the user (1a). Conditionally upon having received the input (INP) from the user (1a), the processing device (110) is configured for causing the communication device (100; 100a) to perform an action (ACT).
