Riding Lawnmower Bagging System with Removable Fairings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lawnmowers are inefficient, loud, and environmentally unfriendly due to their reliance on manual operation or gas-powered engines, failing to meet consumer demands for quiet, clean, and efficient yard maintenance solutions.
Innovation Solution
A riding lawnmower design featuring a seat, mowing deck with cutting implements, a bagging system with a boost system, and fairings that can be removed to reduce width, powered by batteries with a boost system to enhance airflow and debris collection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a bagging system with tube is coupled to the lawnmower for debris collection, then debris collection efficiency is improved, but the lateral width of the lawnmower increases
Solution Approach 1:
The fairing is designed to be removably coupled to the lawnmower frame, allowing the operator to attach it when debris collection is needed and remove it when narrow spaces require passage. This dynamic configuration enables the lawnmower to adapt its lateral width based on operational requirements, resolving the contradiction between debris collection efficiency and lateral width.
2Object-affected harmful factors
If fairings are installed on the lawnmower frame for operator protection, then operator protection is improved, but the lateral width of the lawnmower increases
Solution Approach 1:
The fairing is removably coupled to the lawnmower frame through quick-connect interfaces, enabling the operator to install the fairing for protection during operation and remove it when needing to pass through narrow spaces. This dynamic attachment system resolves the contradiction between operator protection and lateral width by allowing the fairing to be present only when needed.
3Object-affected harmful factors
If the lawnmower is designed with fixed wide fairings for operator protection, then operator protection is improved, but adaptability in confined spaces deteriorates
Solution Approach 1:
The fairing is designed with removable coupling mechanisms that allow it to be attached or detached from the lawnmower frame. This dynamic design provides adaptability in confined spaces by enabling the operator to remove the fairing when needed, while still providing operator protection during normal operation.
Solution Approach 2:
The lawnmower is divided into separable components, with the fairing being a distinct removable element rather than an integrated fixed structure. This segmentation allows the fairing to be independently attached or removed, providing versatility in different operating conditions without compromising operator protection.

AI summary
Lawnmowers are provided. A lawnmower includes a seat configured to receive a lawnmower operator; a mowing deck having one or more cutting implements and a discharge chute; and a bagging system in fluid communication with the discharge chute through a tube, wherein the lawnmower has a first configuration when the tube is coupled to the lawnmower, wherein the lawnmower has a second configuration when the tube is not coupled to the lawnmower, wherein the tube is disposed at a lateral side of the lawnmower in the first configuration, wherein the lawnmower defines a maximum lateral width in a lateral direction, and wherein the lateral width is less than 38 inches in both the first configuration and the second configuration.
