Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless configuration is performed for uplink and downlink devices individually in prior art modes, then connection security and service development are met, but coverage scope is limited and connection fails when distance exceeds signal range

Engineering Contradiction:
Improveconnection securityVSAvoidcoverage scope
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent introduces a relay device as an intermediary between the uplink device and downlink device. This relay device receives configuration information from the uplink device and forwards it to the downlink device, enabling indirect communication when direct connection is not possible due to distance limitations, thereby expanding coverage scope while maintaining connection security through controlled information exchange

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the wireless connection into multiple hops: the uplink device connects to the relay device, which then connects to the downlink device. This segmentation allows each segment to operate within its own coverage range, collectively extending the overall network coverage while maintaining secure configuration through separate management of each segment

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If distance between uplink and downlink devices increases beyond WiFi signal coverage, then network flexibility is improved, but wireless connection is disrupted and user experience deteriorates

Engineering Contradiction:
Improvenetwork flexibilityVSAvoidwireless connection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent adds a temporal dimension to the connection establishment process by introducing a configuration phase before the actual data transmission phase. During the configuration phase, the relay device collects and forwards configuration information, enabling subsequent stable connections even over extended distances, thus maintaining reliability while improving adaptability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If multiple wireless configuration modes are used for different devices, then service development and security requirements are met, but configuration complexity increases and user operation becomes more difficult

Engineering Contradiction:
Improveservice development capabilityVSAvoidconfiguration simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a universal configuration mechanism where the relay device can handle multiple types of configuration information (wireless parameters, authentication data, network settings) through a single unified process. This universal approach maintains the versatility needed for different service requirements while simplifying user operation by presenting a consistent configuration interface regardless of the specific service type

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

AI summary

The present invention discloses a wireless connection method and device, and relates to communication technologies. The method is applicable to establishing a wireless connection device between an uplink device and a downlink device, and includes: obtaining uplink wireless configuration information, and configuring a downlink with the obtained uplink wireless configuration information; and establishing a wireless connection with the uplink device based on the uplink wireless configuration information, and after successful connection establishment, establishing a wireless connection with the downlink device based on the uplink wireless configuration information. The device includes an obtaining module, a configuring module, and a connecting module. The wireless connection device configures the downlink with the uplink wireless configuration information so that the wireless connection device can be connected with the uplink device and the downlink device simultaneously. When the wireless connection between the uplink device and the downlink device goes beyond the coverage scope of signals, the wireless connection device can establish a wireless connection between the uplink device and the downlink device. Thus, the coverage scope of the wireless signals is expanded; the quality of the wireless connection is ensured; the network topology is optimized; and the user experience is improved.
