Push Mower Handle Layout for Flexible Turning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push mowers require users to stop the self-traveling function and reengage it after turning, which is inconvenient due to the poor flexibility of the palm and involves a large range of motion, making the operation time-consuming and labor-intensive.
Innovation Solution
A push power tool design with a first operating member on the handle's side facing away from the user and a second operating member on the side facing the user, allowing flexible operation during turns, along with a sensing device using magnetic elements and sensors to control the traveling mode and output power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blade trigger is placed in the front and the self-traveling trigger in the rear, then the control functions are separated, but the user must release and reengage the palm when turning, making operation inconvenient and time-consuming
Solution Approach 1:
The operating device is divided into two independent operating members: a first operating member for controlling the self-traveling function and a second operating member for controlling the blade trigger. This segmentation allows each function to be controlled independently, so the user can operate the first operating member with the palm while the second operating member remains accessible with the fingers, eliminating the need to release and reengage the palm during turning operations.
2Reliability
If the self-traveling function is stopped during turning, then the control is precise, but the user needs to release the palm and approach the trigger again, increasing labor intensity
Solution Approach 1:
By separating the control functions into two independent operating members, the system maintains reliable control during turning while reducing labor intensity. The first operating member can be operated with the palm for self-traveling control, while the second operating member with fingers handles the blade trigger, allowing continuous operation without repeated palm release and reengagement.
Solution Approach 2:
The operating members are arranged in different spatial dimensions on the handle: the first operating member is positioned on one side and the second operating member on the other side. This dimensional arrangement allows the user to operate both functions simultaneously with different body parts (palm and fingers), maintaining control precision while reducing the physical effort required during turning operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates convenient and efficient operation during turns by allowing separate control of traveling and power functions without needing to release and reengage the palm, saving time and effort.
Implementation Method 1
a sensing device disposed circumferentially relative to the mounting shaft, and the sensing device is configured to sense the operating device. In some examples, the sensing device includes a first magnetic element and a first magnetic sensor.

AI summary
Provided is a push power tool. The push power tool includes a motor, a body, a traveling device, a handle, and an operating device. The motor drives a cutting part to rotate to mow. The body accommodates at least part of the motor. The traveling device includes traveling wheels. The handle is connected to the body and configured for a user to hold. The operating device is configured for the user to operate. The operating device includes a first operating member and a second operating member. The first operating member is movable relative to the handle to control the traveling mode of the push power tool. The second operating member is movable relative to the handle to control the output power of the push power tool. In the push power tool, the first operating member includes a first operating portion disposed on a side of the handle facing away from the user, and the second operating member includes a second operating portion disposed on a side of the handle facing the user so that the first operating portion can be flexibly operated when the push power tool turns, the operation is convenient, and time and efforts are saved.
