Solution Overview

Problem

Battery-operated WLAN client devices consume significant battery life due to the process of network discovery and association, especially when users frequently connect to different networks without saving connection profiles, leading to repetitive entry of connection parameters.

Innovation Solution

Implementing transient connection profiles that can be overwritten and automatically deleted after a period, allowing users to temporarily store connection parameters for networks not prioritized, thus reducing the need for explicit user action and repetitive data entry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users save persistent connection profiles for each WLAN they connect to, then connection parameters are stored for future use, but storage memory is consumed and profiles remain until explicitly deleted

Engineering Contradiction:

Improveconnection process automationVSAvoidstorage memory consumption

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent implements transient connection profiles that are automatically deleted after a predetermined period or after a certain number of uses, replacing the traditional persistent profile model. These transient profiles serve as disposable storage containers that automatically expire, eliminating the need for manual deletion and preventing permanent accumulation of connection data in memory.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the temporal parameter of connection profiles by introducing automatic expiration mechanisms. Profiles are assigned a limited lifespan (either time-based or usage-based), transforming them from permanent persistent storage to temporary transient storage, thereby dynamically managing memory consumption based on actual connection needs.

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If users frequently connect to different WLANs without saving profiles, then storage memory is preserved, but users must repeatedly enter connection parameters

Engineering Contradiction:

Improvestorage memory conservationVSAvoidrepetitive data entry time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

Transient connection profiles provide temporary storage without committing to permanent persistent storage. These profiles are automatically discarded after use or expiration, allowing the system to cache connection parameters briefly to avoid repeated user input without permanently consuming memory resources.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The system performs preliminary action by automatically caching connection parameters in transient profiles during the first connection, so that subsequent connections can occur faster without requiring full user re-entry of parameters, while still maintaining memory efficiency through automatic expiration.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If persistent connection profiles are stored for traveled WLANs, then future connections are faster, but the profiles occupy memory until explicitly deleted

Engineering Contradiction:

Improveconnection speedVSAvoidmemory occupation

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent replaces persistent profiles with transient profiles that have automatic expiration. This allows the system to maintain connection profiles for traveled WLANs to enable fast reconnection, while automatically cleaning up old profiles to prevent permanent memory occupation, thus balancing connection speed with memory conservation.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

4Ease of operation

If the client device scans for networks and presents options, then users can select networks to join, but battery life is consumed during the scanning and association process

Engineering Contradiction:

Improvenetwork selection capabilityVSAvoidbattery consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by automatically scanning for and caching transient profiles of available networks in advance. When a user needs to connect, the device can quickly present pre-identified network options with cached connection parameters, reducing the time and energy required for full scanning and parameter entry during actual connection events.

Inventive Principle:

Principle #10Preliminary action

AI summary

A wireless local area network (WLAN) client device is able to store one or more transient connection profiles. A transient connection profile of a WLAN may be overwritten by a transient connection profile of another WLAN. A transient connection profile may be automatically deleted from the client device without user action having been taken to explicitly delete the transient connection profile.
