Mower Chassis Interchangeable Gear Plate Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mowers lack versatility and efficiency in height adjustment mechanisms, with household mowers requiring simplified operation and compact storage, while professional mowers prioritize stability and service life over operation steps, leading to differing design requirements for adjustment and operating mechanisms.
Innovation Solution
A mower design featuring a chassis with interchangeable adjustment mechanisms and handle mechanisms, allowing adaptation to different use modes with a gear plate system for height adjustment, and a battery pack configuration that optimizes weight distribution and space utilization, ensuring stability and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the push device is made foldable, telescopic, or rotatable for easy storage, then the storage convenience is improved, but the structural complexity increases
Solution Approach 1:
The push device is divided into multiple segments that can be folded relative to each other, allowing the device to be collapsed into a compact form for storage while maintaining the basic functional structure when deployed
Solution Approach 2:
The push device incorporates movable joints and articulations that allow it to transition between extended and folded states, providing dynamic adaptability for both operational and storage configurations
2Adaptability or versatility
If a complex transmission and linkage mechanism is provided for professional mower functionality, then the operational capability is improved, but the service life and usage stability deteriorate
Solution Approach 1:
The complex transmission and linkage mechanisms are removed from the chassis structure, extracting only the essential functions needed for operation while eliminating the components that would reduce service life and stability
Solution Approach 2:
The simplified chassis is designed to accommodate different types of push devices and mowing mechanisms through standardized mounting interfaces, allowing one basic chassis structure to serve multiple operational purposes without requiring complex internal mechanisms
3Adaptability or versatility
If the chassis is designed for multiple use modes with interchangeable components, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The chassis is pre-equipped with multiple mounting portions and attachment points during manufacturing, allowing different push devices and configurations to be quickly installed and removed without requiring modifications to the basic chassis structure
Solution Approach 2:
The chassis design allows for easy adjustment of mounting parameters such as height, angle, and position through interchangeable components, enabling the same chassis to adapt to different operational requirements by changing external attachments rather than internal structure

AI summary
A push power tool includes a chassis. The chassis accommodates at least part of a mowing element. An adjustment mechanism is used for adjusting the mowing height. The chassis includes a first mounting portion for mounting a first gear plate, a second mounting portion for selectively mounting a second gear plate, and a third mounting portion for selectively mounting a connection mechanism for connecting a front wheel set to a rear wheel set. The chassis of the mower and the push power tool adopting the preceding solutions have good versatility.
