Riding Mower Shutter Remote Control Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing riding type mowers require the driver to leave their seat to operate the shutter for the discharge port, resulting in a significant workload and inefficiency.
Innovation Solution
A riding type mower with a shutter operating tool integrated into the operation part, allowing remote operation of the shutter moving mechanism and lock mechanism, linked through either a mechanical displacement transmitting mechanism or an electronic control system, enabling the driver to control the shutter from their seat without leaving the driver's seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shutter is operated manually by accessing the mower deck, then the shutter can be opened and closed, but the driver must leave the driver's seat which increases workload and reduces efficiency
Solution Approach 1:
The patent introduces an intermediary mechanism (shutter operating tool with linkage system) that allows the driver to operate the shutter from the driver's seat without physically accessing the mower deck. The operating tool acts as a mediator, transmitting the driver's operational input through a linkage mechanism to actuate the shutter remotely.
Solution Approach 2:
The patent replaces the direct mechanical access system with a remote-operated mechanical transmission system. Instead of the driver directly manipulating the shutter mechanism on the mower deck, the system uses an operating tool with linkage or cable mechanisms to transmit motion remotely, substituting the direct mechanical interaction with a remote-controlled mechanical transmission.
2Ease of operation
If the shutter is made operable from the operation part, then the driver can control the shutter without leaving the seat, but the system complexity increases due to additional mechanisms
Solution Approach 1:
The shutter operating tool is designed to perform multiple functions: it can both open/close the shutter and operate the lock mechanism through the same integrated tool. This multi-functionality reduces the need for separate controls and minimizes overall system complexity while maintaining ease of operation.
Solution Approach 2:
The patent merges the shutter operating mechanism and lock mechanism into a single integrated control system. The operating tool simultaneously controls both the shutter movement and the locking function, combining what could be separate complex systems into one unified mechanism.
3Reliability
If a lock mechanism is added to prevent unintended shutter movement, then shutter stability is improved, but the device complexity increases
Solution Approach 1:
The lock mechanism is designed to automatically engage and disengage based on the shutter's position and operational state. The system uses the existing operational movements and forces to activate the locking function without requiring separate complex control systems, allowing the lock mechanism to serve itself through the natural operations of the shutter system.

AI summary
A riding type mower includes: a vehicle body, a driver's seat mounted on the vehicle body; an operation part arranged around the driver's seat; a mower unit provided on the vehicle body; a shutter for closing a discharge port; a shutter moving mechanism for moving the shutter between a close position closing the discharge port and an open position opening the discharge port; and a lock mechanism for locking the shutter at the close position. The mower unit includes: a mower deck; a cutting blade installed inside the mower deck; the discharge port formed in the mower deck, through which mown grass cut by the blade is discharge from the mower unit to outside. A shutter operating tool for remotely operating the shutter moving mechanism to open and close the shutter is provided in the operation part. The lock mechanism is remotely operable from the operation part.
