Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mowers face inefficiencies due to the need to turn around and reposition after each charging cycle, which increases operational burden and reduces efficiency.

Innovation Solution

A control method that allows the mower to exit a charging station by a preset distance, bypass it, and operate on the opposite side, using precise positioning and magnetic induction to optimize path planning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the mower returns to the charging station for charging and then performs an in-place turnaround to resume mowing, then the mower can continue operation, but the operation efficiency is significantly reduced due to unnecessary turns and posture adjustments

Engineering Contradiction:

Improveoperation efficiencyVSAvoidtime for turns and posture adjustment

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

Instead of having the mower turn around at the charging station entrance after charging, the invention inverts the approach by having the mower exit from the back side of the charging station. This reversal of the exit direction eliminates the need for in-place turnaround maneuvers, allowing the mower to directly resume mowing operations without unnecessary rotations and posture adjustments, thereby significantly improving operational efficiency

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The invention applies preliminary action by pre-positioning the charging station such that its back side faces the working region. This preliminary arrangement allows the mower to exit the charging station in a direction that is already aligned with the mowing path, eliminating the need for post-charging repositioning and turns, thus saving time and improving efficiency

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the mower performs in-place turnaround and posture adjustment after charging, then the mower can resume mowing, but the burden on the mower is increased

Engineering Contradiction:

Improveoperational burdenVSAvoidcontrol complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

By inverting the exit direction of the charging station to face the working region, the invention eliminates the complex in-place turnaround and posture adjustment maneuvers. The mower simply exits straight from the back side of the charging station and continues mowing, significantly reducing operational burden and control complexity

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A control method for a mower. The method comprises: when charging of a mower (101) has been completed, controlling the mower (101) to exit by a first preset distance from an entrance and exit side of a charging station (102) to reach a first preset position, then controlling the mower (101) to move forward from the first preset position and bypass the charging station (102), so as to reach a back side of the charging station (102), the back side being opposite to the entrance and exit side, and subsequently, performing an operation at the back side of the charging station (102). Thus, after charging is completed at a charging station, a mower can perform an operation on the other side of the charging station, thereby improving the operation efficiency of the mower. A control device for a mower, and a storage medium are further involved.
