Rotatable Accumulator Hatch Access for Agricultural Powertrain Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural vehicles face challenges in accessing the engine or transmission for maintenance due to the design that prohibits direct access when in operational states, requiring a method to transition between states for access without compromising functionality.
Innovation Solution
An agricultural vehicle system and method that includes a frame with a hatch, an accumulator, and a module builder that can be rotated to provide access to the powertrain by detaching the accumulator from the frame and attaching it to the module builder, allowing for access through a defined hatch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the accumulator and module builder are fixed in position to maintain operational functionality, then the vehicle can perform harvesting operations, but access to the powertrain through the hatch is prohibited
Solution Approach 1:
The accumulator and module builder are designed to be movable rather than fixed, allowing them to rotate between operational positions (blocking the hatch) and maintenance positions (providing access to the hatch). This dynamic repositioning enables the system to switch between maintaining harvesting functionality and providing powertrain access as needed.
Solution Approach 2:
The system is divided into separable components (accumulator and module builder) that can be independently positioned and rotated. This segmentation allows the components to be moved out of the way during maintenance while maintaining their functional integrity during operation, resolving the contradiction between access and functionality.
2Ease of repair
If the hatch is always accessible for maintenance, then powertrain access is improved, but the operational configuration for harvesting is compromised
Solution Approach 1:
The hatch accessibility is made dynamic by coupling it with the movable accumulator and module builder. During maintenance, the components are rotated to open the hatch; during operation, they return to their functional positions to block the hatch, ensuring both ease of repair and operational reliability are maintained at different times.
Solution Approach 2:
The system is designed in advance with the capability to reposition components before maintenance is needed. The accumulator and module builder can be rotated to accessible positions prior to repair operations, ensuring the hatch is ready for maintenance without compromising operational functionality when not in use.
3Stability of the object's composition
If the accumulator is attached to the frame to provide structural support, then stability is improved, but access to the hatch is blocked
Solution Approach 1:
The attachment of the accumulator to the frame is made dynamic through a rotatable connection rather than a fixed rigid attachment. This allows the accumulator to maintain structural support when in operational position while enabling rotation to open the hatch for maintenance, resolving the contradiction between stability and accessibility.
Solution Approach 2:
The structural support function is segmented from the access blocking function. The accumulator maintains structural attachment to the frame while being capable of rotational movement, separating the stabilizing function from the hatch-blocking function, allowing both to be optimized for their respective purposes.

AI summary
An agricultural vehicle for picking or harvesting a product includes a motor, a plurality of tires, a transmission mating the motor to the plurality of tires, an accumulator operable to store the product, a module builder operable to receive the product from the accumulator, and a frame supporting the accumulator and the module builder. The frame defines a hatch through which an operator is capable of accessing the motor and/or the transmission. The agricultural vehicle is operable to transition between a first state and a second state. In the first state, the module builder and the accumulator prohibit access through the hatch. In the second state, the module builder and the accumulator are rotated relative to the frame and provide access through the hatch.
