Lawnmower Bagging Frame With Pivoting Access From the Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face difficulty in accessing and emptying the bagging system of lawnmowers, particularly riding lawnmowers, requiring them to dismount to perform these tasks.
Innovation Solution
A lawnmower design featuring a bagging frame with a first and second section pivotally coupled through a magnetic interface, allowing the bagging system to be operated from a seated position without dismounting, facilitated by a handle and a quick release mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bagging system is fixed to the lawnmower frame, then the bagging system remains stable during operation, but the operator cannot access the bagging system while riding the lawnmower
Solution Approach 1:
The bagging frame is divided into a first section that is fixed to the lawnmower frame and a second section that is movable relative to the first section. This segmentation allows the bagging system to remain stable during operation while enabling the operator to access and empty the bag from a seated position by moving the second section.
Solution Approach 2:
The bagging system transitions from a completely fixed structure to a dynamic structure where the second section can move relative to the first section through a pivot point. This dynamic capability allows the operator to access the bagging system during operation while the system remains stable when locked in position.
2Productivity
If the operator dismounts to empty the bag, then the bag can be emptied completely, but the mowing process is interrupted
Solution Approach 1:
A handle is provided as an intermediary mechanism that the operator can manipulate from a seated position to move the second section of the bagging frame. This allows the operator to empty the bag without dismounting, maintaining continuous mowing operation while still achieving complete bag emptying.
Solution Approach 2:
The bagging system is designed to be self-accessible during operation through the movable second section and handle mechanism. The operator can service the bag (empty it) while remaining seated on the lawnmower, eliminating the need to stop the mowing process for bag maintenance.
3Ease of operation
If the bagging frame is made movable, then the operator can access the bag from a seated position, but the bagging system becomes more complex
Solution Approach 1:
The bagging frame is divided into two sections connected by a pivot point, with the second section being movable. This segmentation provides the necessary mobility for operator access while keeping each section relatively simple in structure, avoiding excessive complexity.
Solution Approach 2:
A magnetic release mechanism is used to replace complex mechanical locking systems. The magnetic mechanism provides a simple yet effective means of securing and releasing the movable second section, reducing overall system complexity while maintaining ease of operation.
