Dual-Position Door Control for Farm Implement Bins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gate or door control mechanisms for farm implements are typically configured to be operated from a single position, which can be inconvenient for users, especially when they are positioned on the wrong side of the mechanism during discharge operations.
Innovation Solution
A dual position door control system with two door control assemblies mounted on a base, allowing the door to be operated from either side, featuring a controller and drive mechanism with bevel gears and a rack system that enables the door to be moved between open and closed positions from either side of the gate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-position door control mechanism is used, then the device complexity is reduced, but the ease of operation deteriorates when users are on the wrong side of the mechanism
Solution Approach 1:
The door control mechanism is segmented into two separate control assemblies mounted on opposite sides of the discharge opening. Each assembly includes its own controller and drive mechanism, allowing operators to control the door from either side independently. This segmentation resolves the contradiction by providing multiple access points without requiring a single complex mechanism that serves all positions.
Solution Approach 2:
The door control system is designed with universal functionality by providing identical control assemblies at multiple positions around the discharge opening. Each assembly can independently operate the door, making the system adaptable to operator positions on either side. This multi-functionality improves ease of operation while maintaining relatively simple individual assembly designs.
2Ease of operation
If a dual position door control system is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The dual-position control system is achieved by segmenting the control function into two identical, independent assemblies mounted on opposite sides of the discharge opening. Each assembly contains a controller and drive mechanism that can independently operate the door. This segmentation allows the system to provide enhanced ease of operation while keeping each individual assembly relatively simple in design.
3Productivity
If the control mechanism is positioned on one side only, then the device complexity is minimized, but the loss of time occurs when operators need to walk around the discharge opening
Solution Approach 1:
The control function is segmented and distributed to two separate locations on opposite sides of the discharge opening. This allows operators to access the control mechanism from either side without needing to walk around the discharge opening, eliminating time loss while maintaining simple individual control assemblies.
Solution Approach 2:
The control mechanism is positioned in multiple spatial dimensions (both sides of the discharge opening) rather than a single location. This dimensional distribution allows operators to access controls from any side, eliminating the need to walk around the discharge opening and improving discharge operation efficiency without significantly increasing overall system complexity.
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
Enables operators to control the door from either side without needing to walk around the discharge opening, improving convenience and efficiency during material discharge operations.
Implementation Method 1
each of the drive mechanisms includes a first shaft, a first gear, a second shaft, a second gear, a third gear, a third shaft, a fourth gear, and a fifth gear. The controller is coupled to the first shaft and the first gear is coupled to the first shaft. The first gear is positioned to drive the second gear and the second gear is coupled to a first end of the second shaft. The second end of the second shaft is coupled with the third gear and the third gear is positioned to drive the fourth gear. The fourth gear is coupled to the third shaft and a second end of the third shaft is coupled with a fifth gear. The fifth gear is positioned to adjust the position of the door.
Implementation Method 2
Each drive mechanism further includes a rack configured to be positioned on the door to engage each fifth gear.

AI summary
A door control system for a farm implement with a storage bin having a discharge opening and a door movable by a drive mechanism between open and closed positions relative to the discharge opening includes a dual position door control system. The system includes at least two controllers at spaced positions relative to the door and coupled to a drive mechanism for opening and closing the door.
