Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication techniques that switch from a narrow to a wider communication range can lead to user inconvenience as users are unable to receive services until the connection process is completed, resulting in potential delays.

Innovation Solution

A processing device and system that switch from a first communication range to a second communication range with a smaller transmission power, allowing for mutual authentication and service provision without requiring users to wait for the wider range connection to be established.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If communication range is switched from narrow to wide, then service coverage area is improved, but user wait time increases

Engineering Contradiction:

Improveservice coverage areaVSAvoiduser wait time

Core Design Contradiction:

Area of stationary objectVSLoss of time

Solution Approach 1:

The system performs authentication and service provisioning actions in advance while the user is still in the narrow communication range. By completing the connection process beforehand, the system eliminates waiting time when the user enters the wide communication range, thus resolving the contradiction between expanded service coverage and reduced user wait time.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If communication range is switched from narrow to wide, then service provision capability is improved, but power consumption increases

Engineering Contradiction:

Improveservice provision capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between narrow and wide communication ranges based on service requirements. By using narrow range for authentication and wide range only when necessary for service delivery, the system optimizes power consumption while maintaining service provision capability, resolving the contradiction between adaptability and energy usage.

Inventive Principle:

Principle #15Dynamics

3Reliability

If connection process is completed before service provision, then communication security is improved, but user convenience deteriorates

Engineering Contradiction:

Improvecommunication securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system completes authentication and connection processes in advance while the user is still in the narrow communication range. This preliminary action ensures security requirements are met before service provision begins, eliminating user waiting time and improving convenience without compromising communication security.

Inventive Principle:

Principle #10Preliminary action
