Solution Overview

Problem

Current automatic recharging technologies for mobile devices often fail due to positioning errors, movement of the docking station, or external interference, leading to a high failure rate in locating the docking station for charging.

Innovation Solution

A docking method for mobile devices that involves navigating to a stored target location and performing a regional search by setting boundary thresholds to detect a guidance signal, allowing the device to move under guidance to the docking station, even if the actual location has deviated, thereby increasing the success rate of recharging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile device navigates directly to the stored target location of the docking station, then the navigation process is simple and fast, but the docking success rate is low due to positioning errors and docking station movement

Engineering Contradiction:
Improvedocking success rateVSAvoidsearch process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by performing a regional search in the vicinity of the stored target location before attempting direct docking. The mobile device first scans a predefined search area around the expected docking station position to detect guidance signals, ensuring it locates the actual docking station even if the stored coordinates have deviated. This preliminary search action increases docking reliability without requiring complete redesign of the navigation system.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the mobile device performs a regional search to locate the docking station, then the docking success rate increases, but the time required for docking increases

Engineering Contradiction:
Improvedocking success rateVSAvoiddocking time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies local quality by concentrating the search effort in a localized region around the stored target location rather than performing a global search. The search area is defined by boundary thresholds at predetermined distances from the target location, and the device searches along boundary lines. This localized approach significantly reduces the time required compared to exhaustive search methods while still achieving high docking success rates by focusing computational and temporal resources where the docking station is most likely to be found.

Inventive Principle:
Principle #3Local quality

3Reliability

If the mobile device uses a camera or laser-based sensor to detect identification features, then the docking station can be visually identified, but the system becomes more complex and may fail due to environmental factors

Engineering Contradiction:
Improvedocking station identification accuracyVSAvoidsensor system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies mechanics substitution by replacing complex visual recognition systems (cameras, laser sensors detecting identification features) with a simpler guidance signal detection mechanism. Instead of using optical systems to recognize patterns and features on the docking station, the mobile device uses a receiver to detect electromagnetic guidance signals transmitted by the docking station. This substitution maintains high identification accuracy while significantly reducing system complexity and eliminating vulnerabilities to environmental factors that affect optical systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A docking method executable by a mobile device is provided. The docking method includes obtaining a stored target location of a docking station, and navigating to the target location. The docking method also includes: during the navigation and/or at the target location, based on a determination that a guidance signal is not detected, performing a regional search. The docking method also includes: during the navigation, or at the target location, or during the regional search, based on a determination that the guidance signal is detected, moving, under the guidance of the guidance signal, to the docking station. Performing the regional search includes determining a basic search zone, searching for the guidance signal while moving along boundaries of the basic search zone, and based on a determination that the guidance signal has not been detected when a termination condition is satisfied, terminating the regional search.
