Stand-On Tractor Platform and Rotating Work Function for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stand-on tractors are less stable and lack space for additional tools or accessories due to their smaller size, posing safety and operational efficiency challenges.
Innovation Solution
A stand-on tractor design featuring a rotatable work function that can switch between a use position near the ground and a service position perpendicular to the ground, with a platform for the operator and auxiliary wheels for enhanced stability and accessibility, allowing for easier tool carriage and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the tractor is made smaller to improve maneuverability and storage, then the profile and storage space are reduced, but stability and space for tools/accessories deteriorate
Solution Approach 1:
The work function is made rotatable between a horizontal working position and a vertical storage position. This dynamic configuration allows the tractor to maintain a compact profile during storage while providing full functionality during operation, effectively resolving the contradiction between size and stability.
Solution Approach 2:
The work function transitions from a horizontal plane to a vertical plane through rotation. This dimensional change allows the work function to be positioned above the operator platform when not in use, maximizing ground clearance and maintaining stability without increasing the tractor's horizontal footprint.
2Length of moving object
If the tractor is made smaller to improve maneuverability, then the profile is reduced, but space for additional tools and accessories deteriorates
Solution Approach 1:
The rotatable work function serves multiple purposes: it is the primary working mechanism and also provides mounting space for additional tools and accessories when positioned vertically. This dynamic design maximizes the utility of limited space on the compact tractor.
Solution Approach 2:
The work function structure serves multiple functions: cutting/weeding operation, tool mounting platform, and space for accessories. By making this single component multi-functional, the tractor achieves high versatility without increasing its overall size.
3Productivity
If the work function is positioned near the ground for operation, then work effectiveness is improved, but accessibility for servicing and tool carriage deteriorates
Solution Approach 1:
The work function rotates between horizontal and vertical positions, allowing it to be close to the ground during operation for effective work, and easily accessible during servicing. This dynamic positioning resolves the contradiction between operational effectiveness and maintenance accessibility.
Solution Approach 2:
The work function can be pre-positioned in the vertical service position before maintenance is needed, making tools and components easily accessible to the operator standing on the platform, thereby facilitating quick servicing and tool changes.
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
The design improves stability and operational efficiency by allowing the work function to be easily accessed and serviced, enhancing safety and versatility while maintaining compactness.
Implementation Method 1
A rear end of the platform rests atop a biasing member positioned at the tractor frame rearward end
Implementation Method 2
a rear wheel support frame is rotatably coupled to the tractor frame via a bearing coupler

AI summary
A tractor includes a tractor frame having a forward end and a rearward end. A control unit is positioned between the forward and rearward ends. A front wheel is relatively near the tractor frame forward end, and a rear wheel is relatively distant from the frame forward end. A work function extends forward of the tractor frame forward end. A platform is rotatably secured to the tractor frame and a rear end of the platform rests atop a biasing member positioned at the tractor frame rearward end. The platform has an axis of rotation higher than an axis of the rear wheel and at least as high as an axis of the front wheel.
