Solution Overview

Problem

Existing wireless communication systems lack a straightforward method to control the wireless communication function of wireless adapters, particularly in scenarios where the adapter's connection status and password settings are not consistently managed, complicating the setup and operation of devices like POS systems.

Innovation Solution

A method that determines the connection status of a wireless adapter upon device power-on, enabling or disabling the wireless communication function based on pre-set or automatically generated passwords, and recording the password for user reference, simplifying the configuration process and reducing setup complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wireless communication function is always enabled, then wireless connectivity is available, but security risks increase and power consumption increases

Engineering Contradiction:

Improvewireless connectivity availabilityVSAvoidsecurity risks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by detecting adapter connection status at device startup and monitoring for adapter connections during operation. Passwords are pre-configured or automatically generated before wireless communication begins, ensuring security measures are in place before connectivity is established.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service by automatically generating passwords when none are provided, and autonomously enabling or disabling wireless communication based on adapter detection. The recording device automatically manages the wireless communication function without requiring manual user intervention for each state change.

Inventive Principle:

Principle #25Self-service

2Object-affected harmful factors

If password setup is required before wireless communication, then security is improved, but setup complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoidsetup complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically generating passwords when users do not provide them. The password generation function operates autonomously based on detected adapter connection status, eliminating the need for manual password configuration while maintaining security requirements.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system changes the password parameter automatically based on adapter detection results. When an adapter is detected, the system either uses a pre-configured password or generates a new one, dynamically adjusting the security parameter without requiring manual user input for each scenario.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If the wireless communication function is manually controlled, then user control is maximized, but ease of operation decreases

Engineering Contradiction:

Improveconfiguration simplicityVSAvoiduser control flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The wireless communication function performs self-service by automatically enabling or disabling based on adapter detection. The system monitors adapter connection status and autonomously adjusts the communication function state, eliminating the need for manual user control while simplifying operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously monitoring adapter connection status and using this information to automatically adjust the wireless communication function. The detection result feeds back into the control logic, creating a closed-loop system that adapts to user actions without requiring manual configuration.

Inventive Principle:

Principle #23Feedback

4Ease of operation

If passwords are not recorded, then security is maintained, but user convenience decreases

Engineering Contradiction:

Improveuser convenienceVSAvoidsecurity exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system extracts the password information and records it separately in a recording unit. This allows the password to be stored securely without exposing it during normal operation, enabling user convenience through recorded password retrieval while maintaining security through controlled access to the recorded information.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A recording device 10 determines if a wireless LAN adapter AD was connected when the recording device 10 turned on; and monitors if a wireless LAN adapter AD becomes connected after the recording device 10 turned on. If the wireless LAN adapter AD is connected after the recording device 10 turns on and a password was previously set, the recording device 10 enables a wireless communication function and uses the previously set password for wireless communication through the wireless LAN adapter AD. If the wireless LAN adapter AD is connected after the recording device 10 turns on and a password was not previously set, the recording device 10 automatically generates a new password and enables the wireless communication function using the automatically generated password for wireless communication through the wireless LAN adapter AD.
